Vehicle Maintenance

Truck mechanics are exposed to a variety of hazardous materials. Chemicals pose a wide range of health hazards (such as irritation, sensitization, and carcinogenicity) and physical hazards (such as flammability, corrosion, and reactivity). All general industry standards apply to workers performing maintenance on all types of commercial motor vehicles, as well as all other types of trucks. These standards require conditions, or the use of one or more practices, means, methods, or processes reasonably necessary or appropriate to protect the employees on the job.

The following is an overview of the regulations, training requirements, and general hazard references:
