<p>The post Small things that make all the difference with safety first appeared on Pit & Quarry.</p>

It cannot be overstated that when it comes to safety, the small things you do can make the critical difference between having a normal day and a day you wish you never had.

When working on accident investigations, we often find there was not just one factor that contributed to the accident. Instead, more than one thing went wrong in the critical chain of events.

Any one of these going a different way could have prevented the accident. More often than not, one or more of those occurrences is something you might have considered to be a “small thing” prior to the accident. It was easy to do or not do, but it was also easy to overlook.

Here’s an example from life outside of work: How many of us with children have had our small child dart into the path of oncoming traffic when we assumed they would stay by us as we momentarily let go of their hand?
This happened to one of this article’s authors. Fortunately, the worst was averted because the driver hit the brakes just in time. But it was a heart-stopping moment, and you can be sure it never happened again.
Taking a moment to clasp a hand, look both ways before crossing, watch where you step so you don’t fall down the stairs – these are things we can do in our everyday lives that are simple, yet they can be critical. There are many examples of this at work.

Critical oversights

Sometimes, verbal communication can fail to adequately convey the pivotal message that there is a potential safety issue at hand.

For instance, a miner may speak with a foreman in the breakroom about how they were going to approach a task. The miner was not quite sure he would have the right tools in good enough condition, but he did not come right out and say it. He only seemed reluctant to get started.

The foreman, meanwhile, was focused on getting the work lined out quickly and not really taking the time to think about what the miner might not be saying. If he had, he would have picked up on what really was wrong with what the miner was about to do. If the foreman had slowed down and asked some questions, he might have gotten a clearer picture.

Conversation is often such a quick, small thing, but active listening is the key. A careful foreman will try to make time to look at the jobsite with the miner and talk through how he is going to do the task.

Two things we emphasize in the training we do for supervisors are the importance of follow-up and not making assumptions. These can be related concepts.

Giving someone direction to do something that is important for safety is one thing. But taking the time to check in and make sure it was done properly is the kind of follow-up that provides assurance. It does not rely on an assumption that all is well.

That kind of follow-up both serves to emphasize to others the importance the supervisor places on their safety – he took the time to check on things – and it also provides redundancy. Not one, but two people are taking responsibility to be sure the safety measure is in place.

This level of follow-up is not needed for everything. But when there is a real possibility that it could be wrong to assume conditions are good, then follow-up can be the essential small thing that prevents the worst from occurring.

Follow-up related to documentation is also so important. Taking care to properly complete required records is a prime example. It is too easy to skip steps when filling out workplace exams or pre-operation inspections in order to get work underway. Although this may seem like just paperwork to some, these records serve an important safety function to report hazards that need attention.

The same is true when it comes to Mine Safety & Health Administration (MSHA)-required training records. MSHA’s standards in 30 C.F.R. Part 46 provide considerable detail on what needs to be included in a training record. This ensures the proper level of training was provided in a timely manner. Such clarity makes it relatively easy to ensure compliance, but because so much is required in every record, it is also easy to make a mistake.

Taking a few extra minutes to check the record as you go about completing it can catch these errors before they create a much more complicated situation.

The new MSHA Information Hub aims to provide miners and operators with clearer guidance on safety standards and regulatory compliance.

<p>The post MSHA information center emerges through new government program first appeared on Pit & Quarry.</p>

The U.S. Department of Labor launched an opinion letter program that spans five of its enforcement agencies – including the Mine Safety & Health Administration (MSHA).

As part of the program, MSHA will now provide compliance-assistance resources through the new MSHA Information Hub, a centralized platform offering guidance, regulatory updates, training materials and technical support.

As the Labor Department describes, the opinion letter program illustrates its commitment to providing meaningful compliance assistance that helps workers, employers and other stakeholders understand how federal labor laws apply in specific workplace situations.

“Opinion letters are an important tool in ensuring workers and businesses alike have access to clear, practical guidance,” says Keith Sonderling, deputy secretary of labor. “Launching this program is part of our broader effort to empower the public with the information they need to understand and comply with the laws the department enforces.”

Opinion letters provide official written interpretations from the department’s enforcement agencies, explaining how laws apply to specific factual circumstances presented by individuals or organizations. By addressing real-world questions, the Labor Department says opinion letters promote clarity, consistency and transparency in the application of federal labor standards.

To support its effort, the Labor Department launched a webpage at dol.gov/opinion-letters so users can explore past guidance and have an easy way to submit new requests to the appropriate agency.

The Laber Department’s opinion letter program also applies to the Wage & Hour Division, the Occupational Safety & Health Administration, the Employee Benefits Security Administration and Veterans’ Employment & Training Service.

The U.S. Geological Survey’s latest production statistics show a 6 percent decline for crushed stone and a 5 percent drop for sand and gravel.

<p>The post Aggregate production falls for fifth straight quarter first appeared on Pit & Quarry.</p>

Aggregate production fell again in the first quarter, marking the industry’s fifth consecutive quarterly decline.

The U.S. Geological Survey (USGS) estimates that nationwide production dropped 6 percent year-over-year to 430 million metric tons. By comparison, USGS reported a 3.9 percent year-over-year decline in the first quarter of 2024.

According to the agency, the last quarterly increase in aggregate production occurred in the fourth quarter of 2023.

In this year’s first quarter, aggregate production declined across all nine geographic divisions the agency tracks. Production dropped in 32 of 40 states USGS measures, with the exceptions being Arkansas, Colorado, Idaho, Maryland, Minnesota, South Carolina, South Dakota and Tennessee

The top five aggregate-producing states by volume in the quarter were Texas, California, Florida, North Carolina and Missouri. Their combined production total was 152 million metric tons.

Minnesota had the largest percentage increase in the first quarter, producing 12 percent more aggregates versus the first quarter of 2024. Kansas experienced the largest percentage drop, down 31 percent from the prior-year period.

Crushed stone

Of the estimated 430 million metric tons of aggregates produced in the first quarter, 273 million metric tons were crushed stone.

Crushed stone production was also down 6 percent in the first quarter versus the prior-year period.

Production was down in all nine of USGS’s geographic divisions. Production decreased in 38 of the 46 states the agency measured, with the exceptions being Arizona, Arkansas, Maryland, Minnesota, North Carolina, South Carolina, Tennessee and Wisconsin.

Texas, Florida, North Carolina, Missouri and Pennsylvania were the nation’s top five crushed stone-producing states in the first quarter by volume. Their combined total was 108 million metric tons.

Minnesota led all states with a 15.3 percent increase in crushed stone production. Michigan had the largest percentage decline, producing 37 percent less than the prior-year period.

Sand and gravel

Sand and gravel production, meanwhile, dropped 5 percent in the first quarter. The nation’s quarterly production totaled 156 million metric tons.

Production declined in all nine of USGS’s geographic divisions and in 32 of the 42 states USGS estimated. The 10 states that produced more sand and gravel in the first quarter were California, Colorado, Idaho, Illinois, Minnesota, North Dakota, Oklahoma, South Dakota, Tennessee and Utah.

By volume, the top five sand and gravel-producing states in the first quarter were Texas, California, Arizona, Washington and Florida. The five collectively produced 64 million metric tons.

North Dakota had the largest percentage increase in the quarter at 84.5 percent. Montana had the largest percentage drop at 31.7 percent.

About USGS’s data

USGS collects data for its quarterly production reports based on sample surveys of aggregate-producing companies. Producers share information voluntarily.

In addition to publishing quarterly data on aggregates, the agency shares information it collects about portland and blended cement. Based on data cement producers recently shared, USGS estimates shipments of portland and blended cement decreased 8 percent in the first quarter.

Get answers to top questions on articulated haulers in quarries from an excerpt from the 2025 Pit & Quarry University Handbook.

<p>The post Hauling | P&Q University Handbook first appeared on Pit & Quarry.</p>

Editor’s note: Over the next five months, the magazine will present excerpts from the 2025 edition of the Pit & Quarry University Handbook that will be published this November. P&Q spotlights hauling this month.

Articulated haul trucks are a common sight in quarries. These robust machines play a crucial role in moving materials efficiently.

If you’re new to the industry or just want to know more about them, here are the basics.

About articulated haul trucks

Articulated haul trucks, also referred to as articulated dump trucks (ADTs), articulated haulers, off-road haul trucks or “artics” – are heavy-duty vehicles designed to transport materials over rough terrain.

The term “articulated” refers to its design: two-body sections connected by a pivoting joint. This articulation allows the truck to steer by bending at this joint, giving it excellent maneuverability and the ability to navigate uneven ground.

Think of it like a human waist, allowing the upper and lower body to move somewhat independently.

Artics in the quarry

These trucks are primarily used for hauling overburden, blasted rock and aggregates like crushed stone, sand and gravel from extraction sites to processing areas, stockpiles or loading zones. They’re workhorses that keep material flowing within quarry operations.

So, what are the advantages of using articulated haul trucks in a quarry compared to other types?

• Superior maneuverability. The articulated steering allows these trucks to navigate tight corners and confined spaces much more easily than rigid-frame trucks. This is particularly useful in quarries with challenging layouts or when working in active digging areas.

• Excellent off-road capability. Their design, which often includes all-wheel drive and robust suspension systems, allows them to travel over uneven or slippery terrain where on-road or rigid-frame trucks might struggle.

• Lower ground pressure. Compared to some rigid-frame trucks, ADTs often have a lower ground pressure due to their wider tire configurations and weight distribution. This helps minimize damage to haul roads and allows them to operate in softer ground conditions.

Articulated haulers versus on-road dump trucks

On-road dump trucks are primarily designed and built for transporting materials on paved surfaces and public roads. They adhere to regulations regarding size, weight and safety features for highway use.

Articulated haulers, on the other hand, are specifically engineered for off-road use in demanding environments like quarries and construction sites. They typically feature a more robust construction to withstand rugged conditions, all-wheel drive for better traction on loose or uneven surfaces, and a greater hauling capacity relative to their size.

Think of it this way: An on-road dump truck is like a delivery van built for city streets, while an articulated dump truck is a specialized all-terrain vehicle built to move heavy loads across rough landscapes.

Final thoughts

Articulated haulers are essential for the efficient operation of modern quarries, offering a blend of maneuverability and off-road capability that makes them ideal for the unique challenges of material transport in these environments.

Understanding their purpose and advantages demonstrates why they’re such a common and valuable piece of equipment for the industry.

<p>The post Small things that make all the difference with safety first appeared on Pit & Quarry.</p>

It cannot be overstated that when it comes to safety, the small things you do can make the critical difference between having a normal day and a day you wish you never had.

When working on accident investigations, we often find there was not just one factor that contributed to the accident. Instead, more than one thing went wrong in the critical chain of events.

Any one of these going a different way could have prevented the accident. More often than not, one or more of those occurrences is something you might have considered to be a “small thing” prior to the accident. It was easy to do or not do, but it was also easy to overlook.

Here’s an example from life outside of work: How many of us with children have had our small child dart into the path of oncoming traffic when we assumed they would stay by us as we momentarily let go of their hand?
This happened to one of this article’s authors. Fortunately, the worst was averted because the driver hit the brakes just in time. But it was a heart-stopping moment, and you can be sure it never happened again.
Taking a moment to clasp a hand, look both ways before crossing, watch where you step so you don’t fall down the stairs – these are things we can do in our everyday lives that are simple, yet they can be critical. There are many examples of this at work.

Critical oversights

Sometimes, verbal communication can fail to adequately convey the pivotal message that there is a potential safety issue at hand.

For instance, a miner may speak with a foreman in the breakroom about how they were going to approach a task. The miner was not quite sure he would have the right tools in good enough condition, but he did not come right out and say it. He only seemed reluctant to get started.

The foreman, meanwhile, was focused on getting the work lined out quickly and not really taking the time to think about what the miner might not be saying. If he had, he would have picked up on what really was wrong with what the miner was about to do. If the foreman had slowed down and asked some questions, he might have gotten a clearer picture.

Conversation is often such a quick, small thing, but active listening is the key. A careful foreman will try to make time to look at the jobsite with the miner and talk through how he is going to do the task.

Two things we emphasize in the training we do for supervisors are the importance of follow-up and not making assumptions. These can be related concepts.

Giving someone direction to do something that is important for safety is one thing. But taking the time to check in and make sure it was done properly is the kind of follow-up that provides assurance. It does not rely on an assumption that all is well.

That kind of follow-up both serves to emphasize to others the importance the supervisor places on their safety – he took the time to check on things – and it also provides redundancy. Not one, but two people are taking responsibility to be sure the safety measure is in place.

This level of follow-up is not needed for everything. But when there is a real possibility that it could be wrong to assume conditions are good, then follow-up can be the essential small thing that prevents the worst from occurring.

Follow-up related to documentation is also so important. Taking care to properly complete required records is a prime example. It is too easy to skip steps when filling out workplace exams or pre-operation inspections in order to get work underway. Although this may seem like just paperwork to some, these records serve an important safety function to report hazards that need attention.

The same is true when it comes to Mine Safety & Health Administration (MSHA)-required training records. MSHA’s standards in 30 C.F.R. Part 46 provide considerable detail on what needs to be included in a training record. This ensures the proper level of training was provided in a timely manner. Such clarity makes it relatively easy to ensure compliance, but because so much is required in every record, it is also easy to make a mistake.

Taking a few extra minutes to check the record as you go about completing it can catch these errors before they create a much more complicated situation.

The new MSHA Information Hub aims to provide miners and operators with clearer guidance on safety standards and regulatory compliance.

<p>The post MSHA information center emerges through new government program first appeared on Pit & Quarry.</p>

The U.S. Department of Labor launched an opinion letter program that spans five of its enforcement agencies – including the Mine Safety & Health Administration (MSHA).

As part of the program, MSHA will now provide compliance-assistance resources through the new MSHA Information Hub, a centralized platform offering guidance, regulatory updates, training materials and technical support.

As the Labor Department describes, the opinion letter program illustrates its commitment to providing meaningful compliance assistance that helps workers, employers and other stakeholders understand how federal labor laws apply in specific workplace situations.

“Opinion letters are an important tool in ensuring workers and businesses alike have access to clear, practical guidance,” says Keith Sonderling, deputy secretary of labor. “Launching this program is part of our broader effort to empower the public with the information they need to understand and comply with the laws the department enforces.”

Opinion letters provide official written interpretations from the department’s enforcement agencies, explaining how laws apply to specific factual circumstances presented by individuals or organizations. By addressing real-world questions, the Labor Department says opinion letters promote clarity, consistency and transparency in the application of federal labor standards.

To support its effort, the Labor Department launched a webpage at dol.gov/opinion-letters so users can explore past guidance and have an easy way to submit new requests to the appropriate agency.

The Laber Department’s opinion letter program also applies to the Wage & Hour Division, the Occupational Safety & Health Administration, the Employee Benefits Security Administration and Veterans’ Employment & Training Service.

The U.S. Geological Survey’s latest production statistics show a 6 percent decline for crushed stone and a 5 percent drop for sand and gravel.

<p>The post Aggregate production falls for fifth straight quarter first appeared on Pit & Quarry.</p>

Aggregate production fell again in the first quarter, marking the industry’s fifth consecutive quarterly decline.

The U.S. Geological Survey (USGS) estimates that nationwide production dropped 6 percent year-over-year to 430 million metric tons. By comparison, USGS reported a 3.9 percent year-over-year decline in the first quarter of 2024.

According to the agency, the last quarterly increase in aggregate production occurred in the fourth quarter of 2023.

In this year’s first quarter, aggregate production declined across all nine geographic divisions the agency tracks. Production dropped in 32 of 40 states USGS measures, with the exceptions being Arkansas, Colorado, Idaho, Maryland, Minnesota, South Carolina, South Dakota and Tennessee

The top five aggregate-producing states by volume in the quarter were Texas, California, Florida, North Carolina and Missouri. Their combined production total was 152 million metric tons.

Minnesota had the largest percentage increase in the first quarter, producing 12 percent more aggregates versus the first quarter of 2024. Kansas experienced the largest percentage drop, down 31 percent from the prior-year period.

Crushed stone

Of the estimated 430 million metric tons of aggregates produced in the first quarter, 273 million metric tons were crushed stone.

Crushed stone production was also down 6 percent in the first quarter versus the prior-year period.

Production was down in all nine of USGS’s geographic divisions. Production decreased in 38 of the 46 states the agency measured, with the exceptions being Arizona, Arkansas, Maryland, Minnesota, North Carolina, South Carolina, Tennessee and Wisconsin.

Texas, Florida, North Carolina, Missouri and Pennsylvania were the nation’s top five crushed stone-producing states in the first quarter by volume. Their combined total was 108 million metric tons.

Minnesota led all states with a 15.3 percent increase in crushed stone production. Michigan had the largest percentage decline, producing 37 percent less than the prior-year period.

Sand and gravel

Sand and gravel production, meanwhile, dropped 5 percent in the first quarter. The nation’s quarterly production totaled 156 million metric tons.

Production declined in all nine of USGS’s geographic divisions and in 32 of the 42 states USGS estimated. The 10 states that produced more sand and gravel in the first quarter were California, Colorado, Idaho, Illinois, Minnesota, North Dakota, Oklahoma, South Dakota, Tennessee and Utah.

By volume, the top five sand and gravel-producing states in the first quarter were Texas, California, Arizona, Washington and Florida. The five collectively produced 64 million metric tons.

North Dakota had the largest percentage increase in the quarter at 84.5 percent. Montana had the largest percentage drop at 31.7 percent.

About USGS’s data

USGS collects data for its quarterly production reports based on sample surveys of aggregate-producing companies. Producers share information voluntarily.

In addition to publishing quarterly data on aggregates, the agency shares information it collects about portland and blended cement. Based on data cement producers recently shared, USGS estimates shipments of portland and blended cement decreased 8 percent in the first quarter.

Get answers to top questions on articulated haulers in quarries from an excerpt from the 2025 Pit & Quarry University Handbook.

<p>The post Hauling | P&Q University Handbook first appeared on Pit & Quarry.</p>

Editor’s note: Over the next five months, the magazine will present excerpts from the 2025 edition of the Pit & Quarry University Handbook that will be published this November. P&Q spotlights hauling this month.

Articulated haul trucks are a common sight in quarries. These robust machines play a crucial role in moving materials efficiently.

If you’re new to the industry or just want to know more about them, here are the basics.

About articulated haul trucks

Articulated haul trucks, also referred to as articulated dump trucks (ADTs), articulated haulers, off-road haul trucks or “artics” – are heavy-duty vehicles designed to transport materials over rough terrain.

The term “articulated” refers to its design: two-body sections connected by a pivoting joint. This articulation allows the truck to steer by bending at this joint, giving it excellent maneuverability and the ability to navigate uneven ground.

Think of it like a human waist, allowing the upper and lower body to move somewhat independently.

Artics in the quarry

These trucks are primarily used for hauling overburden, blasted rock and aggregates like crushed stone, sand and gravel from extraction sites to processing areas, stockpiles or loading zones. They’re workhorses that keep material flowing within quarry operations.

So, what are the advantages of using articulated haul trucks in a quarry compared to other types?

• Superior maneuverability. The articulated steering allows these trucks to navigate tight corners and confined spaces much more easily than rigid-frame trucks. This is particularly useful in quarries with challenging layouts or when working in active digging areas.

• Excellent off-road capability. Their design, which often includes all-wheel drive and robust suspension systems, allows them to travel over uneven or slippery terrain where on-road or rigid-frame trucks might struggle.

• Lower ground pressure. Compared to some rigid-frame trucks, ADTs often have a lower ground pressure due to their wider tire configurations and weight distribution. This helps minimize damage to haul roads and allows them to operate in softer ground conditions.

Articulated haulers versus on-road dump trucks

On-road dump trucks are primarily designed and built for transporting materials on paved surfaces and public roads. They adhere to regulations regarding size, weight and safety features for highway use.

Articulated haulers, on the other hand, are specifically engineered for off-road use in demanding environments like quarries and construction sites. They typically feature a more robust construction to withstand rugged conditions, all-wheel drive for better traction on loose or uneven surfaces, and a greater hauling capacity relative to their size.

Think of it this way: An on-road dump truck is like a delivery van built for city streets, while an articulated dump truck is a specialized all-terrain vehicle built to move heavy loads across rough landscapes.

Final thoughts

Articulated haulers are essential for the efficient operation of modern quarries, offering a blend of maneuverability and off-road capability that makes them ideal for the unique challenges of material transport in these environments.

Understanding their purpose and advantages demonstrates why they’re such a common and valuable piece of equipment for the industry.

• Superior maneuverability. The articulated steering allows these trucks to navigate tight corners and confined spaces much more easily than rigid-frame trucks. This is particularly useful in quarries with challenging layouts or when working in active digging areas.

• Excellent off-road capability. Their design, which often includes all-wheel drive and robust suspension systems, allows them to travel over uneven or slippery terrain where on-road or rigid-frame trucks might struggle.

• Lower ground pressure. Compared to some rigid-frame trucks, ADTs often have a lower ground pressure due to their wider tire configurations and weight distribution. This helps minimize damage to haul roads and allows them to operate in softer ground conditions.

Articulated haulers versus on-road dump trucks

On-road dump trucks are primarily designed and built for transporting materials on paved surfaces and public roads. They adhere to regulations regarding size, weight and safety features for highway use.

Articulated haulers, on the other hand, are specifically engineered for off-road use in demanding environments like quarries and construction sites. They typically feature a more robust construction to withstand rugged conditions, all-wheel drive for better traction on loose or uneven surfaces, and a greater hauling capacity relative to their size.

Think of it this way: An on-road dump truck is like a delivery van built for city streets, while an articulated dump truck is a specialized all-terrain vehicle built to move heavy loads across rough landscapes.

Final thoughts

Articulated haulers are essential for the efficient operation of modern quarries, offering a blend of maneuverability and off-road capability that makes them ideal for the unique challenges of material transport in these environments.

Understanding their purpose and advantages demonstrates why they’re such a common and valuable piece of equipment for the industry.

<p>The post Small things that make all the difference with safety first appeared on Pit & Quarry.</p>

It cannot be overstated that when it comes to safety, the small things you do can make the critical difference between having a normal day and a day you wish you never had.

When working on accident investigations, we often find there was not just one factor that contributed to the accident. Instead, more than one thing went wrong in the critical chain of events.

Any one of these going a different way could have prevented the accident. More often than not, one or more of those occurrences is something you might have considered to be a “small thing” prior to the accident. It was easy to do or not do, but it was also easy to overlook.

Here’s an example from life outside of work: How many of us with children have had our small child dart into the path of oncoming traffic when we assumed they would stay by us as we momentarily let go of their hand?
This happened to one of this article’s authors. Fortunately, the worst was averted because the driver hit the brakes just in time. But it was a heart-stopping moment, and you can be sure it never happened again.
Taking a moment to clasp a hand, look both ways before crossing, watch where you step so you don’t fall down the stairs – these are things we can do in our everyday lives that are simple, yet they can be critical. There are many examples of this at work.

Critical oversights

Sometimes, verbal communication can fail to adequately convey the pivotal message that there is a potential safety issue at hand.

For instance, a miner may speak with a foreman in the breakroom about how they were going to approach a task. The miner was not quite sure he would have the right tools in good enough condition, but he did not come right out and say it. He only seemed reluctant to get started.

The foreman, meanwhile, was focused on getting the work lined out quickly and not really taking the time to think about what the miner might not be saying. If he had, he would have picked up on what really was wrong with what the miner was about to do. If the foreman had slowed down and asked some questions, he might have gotten a clearer picture.

Conversation is often such a quick, small thing, but active listening is the key. A careful foreman will try to make time to look at the jobsite with the miner and talk through how he is going to do the task.

Two things we emphasize in the training we do for supervisors are the importance of follow-up and not making assumptions. These can be related concepts.

Giving someone direction to do something that is important for safety is one thing. But taking the time to check in and make sure it was done properly is the kind of follow-up that provides assurance. It does not rely on an assumption that all is well.

That kind of follow-up both serves to emphasize to others the importance the supervisor places on their safety – he took the time to check on things – and it also provides redundancy. Not one, but two people are taking responsibility to be sure the safety measure is in place.

This level of follow-up is not needed for everything. But when there is a real possibility that it could be wrong to assume conditions are good, then follow-up can be the essential small thing that prevents the worst from occurring.

Follow-up related to documentation is also so important. Taking care to properly complete required records is a prime example. It is too easy to skip steps when filling out workplace exams or pre-operation inspections in order to get work underway. Although this may seem like just paperwork to some, these records serve an important safety function to report hazards that need attention.

The same is true when it comes to Mine Safety & Health Administration (MSHA)-required training records. MSHA’s standards in 30 C.F.R. Part 46 provide considerable detail on what needs to be included in a training record. This ensures the proper level of training was provided in a timely manner. Such clarity makes it relatively easy to ensure compliance, but because so much is required in every record, it is also easy to make a mistake.

Taking a few extra minutes to check the record as you go about completing it can catch these errors before they create a much more complicated situation.

The U.S. Department of Labor launched an opinion letter program that spans five of its enforcement agencies – including the Mine Safety & Health Administration (MSHA).

As part of the program, MSHA will now provide compliance-assistance resources through the new MSHA Information Hub, a centralized platform offering guidance, regulatory updates, training materials and technical support.

As the Labor Department describes, the opinion letter program illustrates its commitment to providing meaningful compliance assistance that helps workers, employers and other stakeholders understand how federal labor laws apply in specific workplace situations.

“Opinion letters are an important tool in ensuring workers and businesses alike have access to clear, practical guidance,” says Keith Sonderling, deputy secretary of labor. “Launching this program is part of our broader effort to empower the public with the information they need to understand and comply with the laws the department enforces.”

Opinion letters provide official written interpretations from the department’s enforcement agencies, explaining how laws apply to specific factual circumstances presented by individuals or organizations. By addressing real-world questions, the Labor Department says opinion letters promote clarity, consistency and transparency in the application of federal labor standards.

To support its effort, the Labor Department launched a webpage at dol.gov/opinion-letters so users can explore past guidance and have an easy way to submit new requests to the appropriate agency.

The Laber Department’s opinion letter program also applies to the Wage & Hour Division, the Occupational Safety & Health Administration, the Employee Benefits Security Administration and Veterans’ Employment & Training Service.

The U.S. Geological Survey’s latest production statistics show a 6 percent decline for crushed stone and a 5 percent drop for sand and gravel.

<p>The post Aggregate production falls for fifth straight quarter first appeared on Pit & Quarry.</p>

Aggregate production fell again in the first quarter, marking the industry’s fifth consecutive quarterly decline.

The U.S. Geological Survey (USGS) estimates that nationwide production dropped 6 percent year-over-year to 430 million metric tons. By comparison, USGS reported a 3.9 percent year-over-year decline in the first quarter of 2024.

According to the agency, the last quarterly increase in aggregate production occurred in the fourth quarter of 2023.

In this year’s first quarter, aggregate production declined across all nine geographic divisions the agency tracks. Production dropped in 32 of 40 states USGS measures, with the exceptions being Arkansas, Colorado, Idaho, Maryland, Minnesota, South Carolina, South Dakota and Tennessee

The top five aggregate-producing states by volume in the quarter were Texas, California, Florida, North Carolina and Missouri. Their combined production total was 152 million metric tons.

Minnesota had the largest percentage increase in the first quarter, producing 12 percent more aggregates versus the first quarter of 2024. Kansas experienced the largest percentage drop, down 31 percent from the prior-year period.

Crushed stone

Of the estimated 430 million metric tons of aggregates produced in the first quarter, 273 million metric tons were crushed stone.

Crushed stone production was also down 6 percent in the first quarter versus the prior-year period.

Production was down in all nine of USGS’s geographic divisions. Production decreased in 38 of the 46 states the agency measured, with the exceptions being Arizona, Arkansas, Maryland, Minnesota, North Carolina, South Carolina, Tennessee and Wisconsin.

Texas, Florida, North Carolina, Missouri and Pennsylvania were the nation’s top five crushed stone-producing states in the first quarter by volume. Their combined total was 108 million metric tons.

Minnesota led all states with a 15.3 percent increase in crushed stone production. Michigan had the largest percentage decline, producing 37 percent less than the prior-year period.

Sand and gravel

Sand and gravel production, meanwhile, dropped 5 percent in the first quarter. The nation’s quarterly production totaled 156 million metric tons.

Production declined in all nine of USGS’s geographic divisions and in 32 of the 42 states USGS estimated. The 10 states that produced more sand and gravel in the first quarter were California, Colorado, Idaho, Illinois, Minnesota, North Dakota, Oklahoma, South Dakota, Tennessee and Utah.

By volume, the top five sand and gravel-producing states in the first quarter were Texas, California, Arizona, Washington and Florida. The five collectively produced 64 million metric tons.

North Dakota had the largest percentage increase in the quarter at 84.5 percent. Montana had the largest percentage drop at 31.7 percent.

About USGS’s data

USGS collects data for its quarterly production reports based on sample surveys of aggregate-producing companies. Producers share information voluntarily.

In addition to publishing quarterly data on aggregates, the agency shares information it collects about portland and blended cement. Based on data cement producers recently shared, USGS estimates shipments of portland and blended cement decreased 8 percent in the first quarter.

Get answers to top questions on articulated haulers in quarries from an excerpt from the 2025 Pit & Quarry University Handbook.

<p>The post Hauling | P&Q University Handbook first appeared on Pit & Quarry.</p>

Editor’s note: Over the next five months, the magazine will present excerpts from the 2025 edition of the Pit & Quarry University Handbook that will be published this November. P&Q spotlights hauling this month.

Articulated haul trucks are a common sight in quarries. These robust machines play a crucial role in moving materials efficiently.

If you’re new to the industry or just want to know more about them, here are the basics.

About articulated haul trucks

Articulated haul trucks, also referred to as articulated dump trucks (ADTs), articulated haulers, off-road haul trucks or “artics” – are heavy-duty vehicles designed to transport materials over rough terrain.

The term “articulated” refers to its design: two-body sections connected by a pivoting joint. This articulation allows the truck to steer by bending at this joint, giving it excellent maneuverability and the ability to navigate uneven ground.

Think of it like a human waist, allowing the upper and lower body to move somewhat independently.

Artics in the quarry

These trucks are primarily used for hauling overburden, blasted rock and aggregates like crushed stone, sand and gravel from extraction sites to processing areas, stockpiles or loading zones. They’re workhorses that keep material flowing within quarry operations.

So, what are the advantages of using articulated haul trucks in a quarry compared to other types?

• Superior maneuverability. The articulated steering allows these trucks to navigate tight corners and confined spaces much more easily than rigid-frame trucks. This is particularly useful in quarries with challenging layouts or when working in active digging areas.

• Excellent off-road capability. Their design, which often includes all-wheel drive and robust suspension systems, allows them to travel over uneven or slippery terrain where on-road or rigid-frame trucks might struggle.

• Lower ground pressure. Compared to some rigid-frame trucks, ADTs often have a lower ground pressure due to their wider tire configurations and weight distribution. This helps minimize damage to haul roads and allows them to operate in softer ground conditions.

Articulated haulers versus on-road dump trucks

On-road dump trucks are primarily designed and built for transporting materials on paved surfaces and public roads. They adhere to regulations regarding size, weight and safety features for highway use.

Articulated haulers, on the other hand, are specifically engineered for off-road use in demanding environments like quarries and construction sites. They typically feature a more robust construction to withstand rugged conditions, all-wheel drive for better traction on loose or uneven surfaces, and a greater hauling capacity relative to their size.

Think of it this way: An on-road dump truck is like a delivery van built for city streets, while an articulated dump truck is a specialized all-terrain vehicle built to move heavy loads across rough landscapes.

Final thoughts

Articulated haulers are essential for the efficient operation of modern quarries, offering a blend of maneuverability and off-road capability that makes them ideal for the unique challenges of material transport in these environments.

Understanding their purpose and advantages demonstrates why they’re such a common and valuable piece of equipment for the industry.

Articulated haul trucks are a common sight in quarries. These robust machines play a crucial role in moving materials efficiently.

If you’re new to the industry or just want to know more about them, here are the basics.

About articulated haul trucks

Articulated haul trucks, also referred to as articulated dump trucks (ADTs), articulated haulers, off-road haul trucks or “artics” – are heavy-duty vehicles designed to transport materials over rough terrain.

The term “articulated” refers to its design: two-body sections connected by a pivoting joint. This articulation allows the truck to steer by bending at this joint, giving it excellent maneuverability and the ability to navigate uneven ground.

Think of it like a human waist, allowing the upper and lower body to move somewhat independently.

Artics in the quarry

These trucks are primarily used for hauling overburden, blasted rock and aggregates like crushed stone, sand and gravel from extraction sites to processing areas, stockpiles or loading zones. They’re workhorses that keep material flowing within quarry operations.

So, what are the advantages of using articulated haul trucks in a quarry compared to other types?

• Superior maneuverability. The articulated steering allows these trucks to navigate tight corners and confined spaces much more easily than rigid-frame trucks. This is particularly useful in quarries with challenging layouts or when working in active digging areas.

• Excellent off-road capability. Their design, which often includes all-wheel drive and robust suspension systems, allows them to travel over uneven or slippery terrain where on-road or rigid-frame trucks might struggle.

• Lower ground pressure. Compared to some rigid-frame trucks, ADTs often have a lower ground pressure due to their wider tire configurations and weight distribution. This helps minimize damage to haul roads and allows them to operate in softer ground conditions.

Articulated haulers versus on-road dump trucks

On-road dump trucks are primarily designed and built for transporting materials on paved surfaces and public roads. They adhere to regulations regarding size, weight and safety features for highway use.

Articulated haulers, on the other hand, are specifically engineered for off-road use in demanding environments like quarries and construction sites. They typically feature a more robust construction to withstand rugged conditions, all-wheel drive for better traction on loose or uneven surfaces, and a greater hauling capacity relative to their size.

Think of it this way: An on-road dump truck is like a delivery van built for city streets, while an articulated dump truck is a specialized all-terrain vehicle built to move heavy loads across rough landscapes.

Final thoughts

Articulated haulers are essential for the efficient operation of modern quarries, offering a blend of maneuverability and off-road capability that makes them ideal for the unique challenges of material transport in these environments.

Understanding their purpose and advantages demonstrates why they’re such a common and valuable piece of equipment for the industry.

Ogletree Deakins’ Bill Doran and Margo Lopez offer perspective based on their accident investigation work.

<p>The post Small things that make all the difference with safety first appeared on Pit & Quarry.</p>

It cannot be overstated that when it comes to safety, the small things you do can make the critical difference between having a normal day and a day you wish you never had.

When working on accident investigations, we often find there was not just one factor that contributed to the accident. Instead, more than one thing went wrong in the critical chain of events.

Any one of these going a different way could have prevented the accident. More often than not, one or more of those occurrences is something you might have considered to be a “small thing” prior to the accident. It was easy to do or not do, but it was also easy to overlook.

Here’s an example from life outside of work: How many of us with children have had our small child dart into the path of oncoming traffic when we assumed they would stay by us as we momentarily let go of their hand?
This happened to one of this article’s authors. Fortunately, the worst was averted because the driver hit the brakes just in time. But it was a heart-stopping moment, and you can be sure it never happened again.
Taking a moment to clasp a hand, look both ways before crossing, watch where you step so you don’t fall down the stairs – these are things we can do in our everyday lives that are simple, yet they can be critical. There are many examples of this at work.

Critical oversights

Sometimes, verbal communication can fail to adequately convey the pivotal message that there is a potential safety issue at hand.

For instance, a miner may speak with a foreman in the breakroom about how they were going to approach a task. The miner was not quite sure he would have the right tools in good enough condition, but he did not come right out and say it. He only seemed reluctant to get started.

The foreman, meanwhile, was focused on getting the work lined out quickly and not really taking the time to think about what the miner might not be saying. If he had, he would have picked up on what really was wrong with what the miner was about to do. If the foreman had slowed down and asked some questions, he might have gotten a clearer picture.

Conversation is often such a quick, small thing, but active listening is the key. A careful foreman will try to make time to look at the jobsite with the miner and talk through how he is going to do the task.

Two things we emphasize in the training we do for supervisors are the importance of follow-up and not making assumptions. These can be related concepts.

Giving someone direction to do something that is important for safety is one thing. But taking the time to check in and make sure it was done properly is the kind of follow-up that provides assurance. It does not rely on an assumption that all is well.

That kind of follow-up both serves to emphasize to others the importance the supervisor places on their safety – he took the time to check on things – and it also provides redundancy. Not one, but two people are taking responsibility to be sure the safety measure is in place.

This level of follow-up is not needed for everything. But when there is a real possibility that it could be wrong to assume conditions are good, then follow-up can be the essential small thing that prevents the worst from occurring.

Follow-up related to documentation is also so important. Taking care to properly complete required records is a prime example. It is too easy to skip steps when filling out workplace exams or pre-operation inspections in order to get work underway. Although this may seem like just paperwork to some, these records serve an important safety function to report hazards that need attention.

The same is true when it comes to Mine Safety & Health Administration (MSHA)-required training records. MSHA’s standards in 30 C.F.R. Part 46 provide considerable detail on what needs to be included in a training record. This ensures the proper level of training was provided in a timely manner. Such clarity makes it relatively easy to ensure compliance, but because so much is required in every record, it is also easy to make a mistake.

Taking a few extra minutes to check the record as you go about completing it can catch these errors before they create a much more complicated situation.

The new MSHA Information Hub aims to provide miners and operators with clearer guidance on safety standards and regulatory compliance.

<p>The post MSHA information center emerges through new government program first appeared on Pit & Quarry.</p>

The U.S. Department of Labor launched an opinion letter program that spans five of its enforcement agencies – including the Mine Safety & Health Administration (MSHA).

As part of the program, MSHA will now provide compliance-assistance resources through the new MSHA Information Hub, a centralized platform offering guidance, regulatory updates, training materials and technical support.

As the Labor Department describes, the opinion letter program illustrates its commitment to providing meaningful compliance assistance that helps workers, employers and other stakeholders understand how federal labor laws apply in specific workplace situations.

“Opinion letters are an important tool in ensuring workers and businesses alike have access to clear, practical guidance,” says Keith Sonderling, deputy secretary of labor. “Launching this program is part of our broader effort to empower the public with the information they need to understand and comply with the laws the department enforces.”

Opinion letters provide official written interpretations from the department’s enforcement agencies, explaining how laws apply to specific factual circumstances presented by individuals or organizations. By addressing real-world questions, the Labor Department says opinion letters promote clarity, consistency and transparency in the application of federal labor standards.

To support its effort, the Labor Department launched a webpage at dol.gov/opinion-letters so users can explore past guidance and have an easy way to submit new requests to the appropriate agency.

The Laber Department’s opinion letter program also applies to the Wage & Hour Division, the Occupational Safety & Health Administration, the Employee Benefits Security Administration and Veterans’ Employment & Training Service.

The U.S. Geological Survey’s latest production statistics show a 6 percent decline for crushed stone and a 5 percent drop for sand and gravel.

<p>The post Aggregate production falls for fifth straight quarter first appeared on Pit & Quarry.</p>

Aggregate production fell again in the first quarter, marking the industry’s fifth consecutive quarterly decline.

The U.S. Geological Survey (USGS) estimates that nationwide production dropped 6 percent year-over-year to 430 million metric tons. By comparison, USGS reported a 3.9 percent year-over-year decline in the first quarter of 2024.

According to the agency, the last quarterly increase in aggregate production occurred in the fourth quarter of 2023.

In this year’s first quarter, aggregate production declined across all nine geographic divisions the agency tracks. Production dropped in 32 of 40 states USGS measures, with the exceptions being Arkansas, Colorado, Idaho, Maryland, Minnesota, South Carolina, South Dakota and Tennessee

The top five aggregate-producing states by volume in the quarter were Texas, California, Florida, North Carolina and Missouri. Their combined production total was 152 million metric tons.

Minnesota had the largest percentage increase in the first quarter, producing 12 percent more aggregates versus the first quarter of 2024. Kansas experienced the largest percentage drop, down 31 percent from the prior-year period.

Crushed stone

Of the estimated 430 million metric tons of aggregates produced in the first quarter, 273 million metric tons were crushed stone.

Crushed stone production was also down 6 percent in the first quarter versus the prior-year period.

Production was down in all nine of USGS’s geographic divisions. Production decreased in 38 of the 46 states the agency measured, with the exceptions being Arizona, Arkansas, Maryland, Minnesota, North Carolina, South Carolina, Tennessee and Wisconsin.

Texas, Florida, North Carolina, Missouri and Pennsylvania were the nation’s top five crushed stone-producing states in the first quarter by volume. Their combined total was 108 million metric tons.

Minnesota led all states with a 15.3 percent increase in crushed stone production. Michigan had the largest percentage decline, producing 37 percent less than the prior-year period.
