Environmental protection agency (eEPA)classifications

The EPA categorize automotive repair facilities as potential sources of environmental contamination due to the hazardous waste they generate. Under the resource conservation and recovery act (rBCRA) these facilities must manage:

Use oil

regulate as a special waste with specific handling requirements
Spend solvents

frequently classify as f list hazardous wastes
Lead acid batteries

consider hazardous due to lead and acid content
Antifreeze

may bbe regulatedas hazardous waste in some states
Contaminated shop rags

subject to specific management requirements

Most automotive repair facilities qualify as small quantity generators (ssags)or rattling small quantity generators ( (qsagso)hazardous waste, which determine their regulatory requirements.

Building code requirements for automotive repair facilities

Base on their hazard classification, automotive repair facilities must meet specific building code requirements:

Construction requirements

Fire-resistant construction

depend on size and proximity to other structures
Fire separation

fire barriers between repair areas and other occupancies
Means of egress

adequate exit routes and emergency lighting
Ventilation systems

mechanical ventilation to remove hazardous vapors and exhaust

Fire protection systems

Fire extinguishers

appropriate type and number base on facility size and hazards
Fire suppression systems

sprinklers or other systems may bbe requireddepend on facility size
Fire alarm systems

may bbe requiredbase on occupancy load and facility size

Specialized areas with additional hazard classifications

Certain specialized areas within automotive repair facilities may have additional or different hazard classifications:

Paint spray booths

Paint spray operations are classified as a higher hazard due to the concentration of flammable vapors and arregulatedte below:

NFPA 33: standard for spray application use flammable or combustible materials
Group h 2 occupancy classification (high hazard )under many building codes

These areas require specialized ventilation, electrical systems, and fire protection measures.

Battery charging areas

Areas dedicate to battery charge present unique hazards:

Hydrogen gas production during charge (explosion hazard )
Corrosive materials (battery acid )
Electrical hazards

These areas require proper ventilation, eye wash stations, and specific electrical classifications.

Safety management in automotive repair facilities
