Perform Housekeeping, Waste Disposal, and Quality Control Documentation
This domain tests the back end of the job: keeping the work area safe and clean, disposing of waste legally, and documenting quality control so the work can be traced and accepted.
Core rules
- Apply 5S or a comparable housekeeping routine: sort, set in order, shine, standardise, sustain. Keep aisles, exits and fire equipment clear.
- Segregate waste at the point of generation: hazardous waste (waste paint, solvent, sludge, contaminated rags, empty containers with residue), recyclable packaging, and general waste. Label containers clearly.
- Store hazardous waste in closed, compatible containers with secondary containment, away from ignition and drains. Never pour paint or solvent into a storm drain or soil.
- Treat solvent-soaked rags as a fire risk: place them in a self-closing metal bin or spread them to dry under control; do not pile them in a corner.
- Follow the waste manifest and licensed-transporter requirements under RA 6969 and local rules. Keep delivery receipts, SDS, mixing logs, inspection reports and disposal records.
- QC documentation should be contemporaneous: date, location, product, batch, ratio, film thickness, weather, inspector and result.
Worked example
At the end of a solvent-based spray job, the crew has half a litre of mixed paint, thinner washings and rags. The wrong move is to pour the washings down the drain and put rags in the general bin. The correct move is to let solids settle, decant clear solvent into a labelled hazardous-waste container, keep sludge in a closed container, place rags in a self-closing metal bin, and record the quantities on the waste manifest.
Traps
- Mixing hazardous and general waste, which makes the whole load hazardous.
- Leaving containers open or unlabelled.
- Back-filling documentation after the client complains.
- Using a drain or open ground as a disposal route.
