Gas Can in Trash Can

Does this gas can in a trash can meet the requirements of secondary containment? I would say yes because the trash can has more volume than the gas can.

Leaky Containment

I wondered why, after several days of rain, this containment had so little water in it. It’s because there are small holes in the bottom and it’s a leaky containment. I hope the generator doesn’t spring a leak.

Diesel exhaust fluid is an additive that reduces nitrogen oxide pollution. While this is a good thing, it still needs to be in secondary containment while on the job site.

Kiddy Pool

The contractor placed this kiddy pool under the light plant motor and drip pan. Oil drips cause a petroleum sheen when rain water is present. The contractor will use spill pads to remove the sheen before discharging the water.

This light plant is sitting on the dock next to Elliot Bay. If the motor leaks, oil will wash into the bay. Many contractors place equipment like this in kiddy pools to contain drips.

Secondary Containment Fail

I told the contractor and the contract specifies that all chemicals and gas-powered tools remain in secondary containment when not in use. So, either they aren’t telling all of the workers and sub-contractors, they aren’t inspecting their site, or maybe they don’t care.
