10 Questions You Should to Know about Mining dump truck

Dump truck drivers are tasked with the important duty of safely transporting paving materials, construction supplies, dirt, or garbage. They operate trucks with open beds designed for the easy transport of rocks, sand, gravel, and more to various job sites.

When interviewing potential dump truck drivers, ideal candidates are those who exhibit reliability, flexibility, and a thorough understanding of road safety regulations. It is prudent to avoid candidates lacking energy, good customer service skills, and clear communication abilities.

Unloading a dump truck can pose significant dangers, especially if the ground is uneven or if the load is being deposited into a pit - a frequent scenario in mining areas. For example, dump trucks carrying loads like coal may encounter higher risks; the load can freeze in cold weather, stick to the bed, and tip the truck over when raised. These risks and preventive measures were highlighted by the Mine Safety and Health Administration (MSHA) in a Safety Alert. Employers across various venues, including coal mines and highway projects, should regularly review safety protocols, especially regarding frozen loads, and ensure drivers receive adequate training to handle such situations correctly.

Driver Incident

In an incident reported by MSHA in February 2017, a driver tragically lost his life when his tractor-trailer coal truck tipped over while attempting to dump a frozen load of coal. The raised bed caused the trailer to tip and the driver was fatally injured trying to jump from the cab. MSHA points out that a raised truck bed can easily tip over due to its size and weight. Factors like uneven ground, an unbalanced load, and underinflated tires can elevate risk. Proper training and adherence to best practices can mitigate these hazards.

Best Practices

MSHA offers several best practices for dump truck operations:

• Maintain properly inflated tires and ensure they are in good condition.
• Use antifreeze in cold climates to stop materials from freezing and sticking. Ensure even load distribution.
• Avoid overloading the upper portion of the truck bed.
• When reversing, keep the truck and trailer straight and move at walking pace.
• Stay in the cab with the seatbelt on throughout the dumping process and never jump from an overturning truck.
• Only dump on level, well-compacted surfaces.

Operators should:

• Install thermometers at dump sites to inform drivers of freezing conditions.
• Comply with MSHA's regulation at 30 CFR 77.1708 to establish and maintain a training program on safety regulations and procedures, ensuring this information is distributed and posted prominently at the mine.

Quantifying Risks

Employers can delve deeper into the topic of dump truck safety through the 2001 National Institute for Occupational Safety and Health (NIOSH) report, "Haulage Truck Dump Site Safety: An Examination of Reported Injuries."

NIOSH emphasizes, "The level of risk is influenced by several factors, including site layout, site stability, truck performance, lighting, equipment operator decision-making, and weather conditions. Essential safety tasks involve assessing work site risks, establishing guidelines for identifying excessive risks, and determining risk reduction measures."

The report details different dump types (e.g., edge dumping, short dumping) and associated risks, along with tailored safety precautions.
