Automotive workshop safety, environment and 5S practices
Domain focus
This section covers workshop safety, environmental control and 5S in an automotive service bay. The exam checks hazard recognition, correct PPE, safe lifting and jacking, fire and chemical safety, waste handling, and whether you can apply 5S as a system rather than a cleaning drive.
Core rules
- Wear safety glasses, gloves and safety footwear for the task; use a respirator for brake dust or paint mist and ear protection near air tools.
- Support a raised vehicle on stands rated for the load; never work under a vehicle held only by a hydraulic jack.
- Keep guards in place, disconnect power before servicing electrical equipment, and treat wet floors as slip hazards.
- Store fuels, solvents and used oil in labelled closed containers; keep MSDS available and segregate used oil, filters, batteries, tyres and metal.
- Use the right extinguisher: CO2 or dry powder for electrical and fuel fires; never water on burning fuel or live electrical equipment.
- 5S means Sort, Set in order, Shine, Standardise and Sustain; each tool has a marked location and each bay has an owner and checklist.
Worked example
A technician spills about 1 L of used engine oil near a drain. The correct reasoning is: stop the source, warn others, contain the spill with absorbent, prevent entry to the drain, collect the contaminated absorbent as hazardous waste, clean the floor with detergent, and record the incident. Water washing the oil into the drain is wrong because it spreads pollution and may violate consent limits.
Traps
Using compressed air to blow brake dust; placing a jack alone under a car; mixing used oil with solvents; choosing water on a fuel fire; treating 5S as a one-day cleanup rather than a sustained standard.
