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.

Diesel Exhaust Fluid
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.

Compost Berm
We rarely use silt fence on smaller airfield projects because: the work areas are nearly flat, are surrounded by grass or pavement, the work takes a few months, usually in the summer or fall. Compost berms are frequently used to: contain water, divert water, prevent site runoff. A secondary benefit is filtration; there is some turbidity reduction. Lastly, when done,. we spread the compost out over the disturbed soil and hydroseed it, enhancing grass growth and eliminating the waste of land-filling silt fence.
