Apply Safety Practices and Environmental Protection
This domain tests whether you can work without harming yourself, the customer, or the surroundings. Expect items on PPE selection, shop hazards, fire response, waste handling, and the Philippine laws that govern emissions and hazardous waste.
Core rules
- Match PPE to the task: goggles when grinding or handling solvents, nitrile gloves for fuel and oil, steel-toe boots for heavy components, ear plugs near air tools, respirator when spraying paint.
- Fuel is a Class B fire hazard. Store it in approved containers away from sparks and grinders, and never use water on a fuel fire - use dry chemical or foam.
- Carbon monoxide is invisible. Never run an engine in a closed shop; route exhaust outdoors.
- Battery charging releases hydrogen. Charge in a ventilated area, keep flames away, and handle electrolyte with goggles and acid-resistant gloves.
- Keep guards fitted, remove the ignition key before touching rotating parts, and avoid loose sleeves, rings, or lanyards near a chain or shaft.
Environmental requirements
- RA 8749 (Clean Air Act) sets emission limits; correct jetting and a functioning exhaust reduce visible smoke.
- RA 9003 requires segregation - used oil, filters, batteries, and solvents are hazardous and go to an accredited hauler or recycler, never to a canal or open trash.
- RA 6969 classifies used oil and lead-acid batteries as hazardous waste.
- Use a drip tray under the drain pan, keep a spill kit, and practice 5S so leaks are spotted early.
Worked example
A technician drains 800 mL of used oil. He places a drip tray, drains into a sealed container labelled "used oil", funnels it into the shop drum, and logs the quantity in the hazardous-waste manifest. The empty oil bottle is punctured and segregated as recyclable plastic. Reasoning: the oil cannot go down the drain, the container must be closed and labelled, and the log proves proper turnover if inspected.
Traps
Water on a fuel fire; dumping oil or coolant into drains; running engines indoors; wearing gloves near a rotating chain or shaft, where they can be pulled in.
