How to store used engine oil and other used lubricants before authorised pickup: containers, bunds, labels, and records.
Container rules that matter in practice
Lids, labels, no food-oil drums reused, secondary containment, away from storm drains.
Time on site
Do not become a mini dump. Book pickup when you hit the recycler's minimum. Overflow is how neighbours complain.
Fire and spill
Used oil burns. Keep extinguishers and a spill kit. Train the night shift, not only the EHS officer.
Link to sale
Storage without an authorised buyer is still risk. List the oil on BioTradX the same week you label the tank.
