A small auto workshop is owned by Dan, and has two employees Mick and Sam. Mick arrives at work
first one morning to discover that the drum containing waste oil that is stored out the back of the
workshop has rusted through and about 100L of waste oil has gone onto the concrete, and into the
gravel carpark. Mick panics and wants to get rid of the oil before Dan arrives, so he gets the hose out to
hose it into the stormwater drain. Luckily, Sam and Dan arrive before he does this, and clean up the oil
using absorbent material.
