Occupational Safety and Health (OSHA) and Environmental Compliance

What this domain tests

This domain tests whether you can set up a safe bay and keep workshop waste lawful. In Malaysia the main duties are under the Occupational Safety and Health Act 1994 (Act 514) and the Environmental Quality Act 1974 (Act 127). Used lubricants, solvents, oily filters and lead-acid batteries are controlled wastes, not general refuse.

Core rules

  • Complete a HIRARC before the job: identify the hazard, rate the risk, then apply controls in order - eliminate, substitute, engineer, administrate, and PPE last.
  • Support a raised vehicle on stands at the specified jacking points. Never work under a vehicle held only by a jack or by air suspension.
  • Keep fuels and solvents in approved, labelled containers with secondary containment; remove ignition sources; use Class B extinguishers for oil/fuel fires and CO2 or dry powder for electrical fires.
  • Segregate waste streams: spent oil, filters, oily rags, solvent, coolant and batteries each go into a labelled container with a lid. Scheduled waste must go to a licensed collector with a manifest.
  • Never discharge oil, coolant or wash water to the drain. Recover refrigerant; do not vent it.
  • Read the SDS before handling a chemical and use the specified gloves, eye protection and ventilation.

Worked example

An apprentice drains 4.5 L of engine oil into the parts-washer drain because the waste drum is full. The oil is a scheduled waste and the drain leads to a grease trap and stormwater. The correct action is to stop, close the drain valve, transfer the oil to a labelled drum with a lid and spill tray, record the quantity, and book collection by a licensed contractor. The full drum should have been exchanged before the job. The job card should show the waste-oil quantity and the manifest number.

Traps

PPE is the last line of defence, not the control. Mixing solvent with waste oil makes the whole load harder to dispose of. Water on a fuel fire spreads it. A missing manifest or unlabelled drum is a compliance failure even if no spill occurred.
