A Mining Contractor Safety Manual provides the written safety programs, policies, procedures, and employee responsibilities needed for contractors performing construction, maintenance, repair, installation, excavation, electrical, mechanical, welding, equipment, transportation, and other services at mine properties.
Mining contractors may work at surface mines, underground mines, quarries, sand and gravel operations, aggregate facilities, processing areas, crushing and screening plants, maintenance facilities, and other locations subject to mine-safety requirements. Depending on the mine, work performed, and employee exposure, contractors may be subject to requirements enforced by the Mine Safety and Health Administration (MSHA) as well as OSHA requirements applicable to work outside MSHA jurisdiction.
A properly developed Mining Contractor Safety Manual should reflect the contractor’s actual work, equipment, employees, mine environments, and customer requirements. It should also recognize that mine-specific rules, hazards, training, and procedures may differ from one mine property to another.
The safety programs needed by a mining contractor depend on the work performed and the mine environments where employees work. A comprehensive manual may include programs covering:
Programs that do not apply to the contractor’s operations can be removed, while additional programs should be included when specialized mining or contractor activities create additional hazards.
Independent contractors performing services or construction at mine properties may have responsibilities under MSHA regulations.
The contractor should determine which requirements apply based on:
The contractor should not assume that compliance with its normal OSHA construction or general-industry programs automatically satisfies requirements applicable at a mine.
Mining contractors should coordinate safety responsibilities with the mine’s production operator before beginning work.
Coordination may address:
Contractor employees should understand both their employer’s safety procedures and applicable mine-specific requirements.
Training requirements depend on the type of mine and the work employees perform.
30 CFR Part 46 generally applies to miners working at shell dredging, sand, gravel, surface stone, surface clay, colloidal phosphate, and surface limestone mines.
30 CFR Part 48 applies to training at other covered mines, including underground mines and other surface mining operations subject to Part 48.
Contractors should determine the applicable training requirements before assigning employees to mine work.
Training obligations may include:
