Occupational Safety and Health in the Automotive Workshop

Domain 1: Occupational Safety and Health in the Automotive Workshop

This section covers the hazards a Level 2 mechanic meets daily and the controls expected before, during and after work. The exam tests legal duty, hazard identification, safe work systems, PPE selection, fire and chemical safety, and safe lifting.

Core rules

  • Under Malaysia's OSHA 1994, employers and workers share duties: provide a safe workplace, follow safe systems, report hazards and accidents.
  • Use HIRARC (hazard identification, risk assessment, risk control) before a job. Eliminate or substitute first; engineering controls next; PPE last.
  • Support every raised vehicle with rated jack stands on a hard, level surface. A hydraulic jack alone is not a support.
  • Ventilate exhaust gas; carbon monoxide is odourless and fatal. Do not run engines in closed bays.
  • Store fuels and solvents in approved containers away from ignition. Use Class B extinguishers for fuel fires; never water.
  • Read the SDS before handling chemicals. Use gloves, eye protection and respiratory protection as specified.
  • Lock out and tag out electrical, hydraulic and compressed-air energy before maintenance. Release stored pressure.
  • Keep walkways clear, clean spills immediately, and store tools so they cannot fall.

Worked example

A technician charges a lead-acid battery in a corner bay. Hydrogen gas is produced near the end of charging. The safe reasoning: move the charger to a ventilated area, remove ignition sources, wear goggles and acid-resistant gloves, keep the vent caps in place, and have an eyewash nearby. Do not smoke or create sparks when connecting or disconnecting clamps; connect the positive first and disconnect the negative first to reduce spark risk at the battery.

Traps

  • Treating PPE as the only control.
  • Using water on a petrol or solvent fire.
  • Working under a vehicle held only by a jack.
  • Assuming a battery is safe because it is sealed.
  • Ignoring silica dust, paint mist or refrigerant exposure.
