Devices for keeping hazardous waste containers
Hazardous waste containers
remain closed except when adding or removing
waste. Several commercially available devices
may be acceptable for closing a hazardous waste
container if the devices are properly used and
- The device must prevent the escape of vapors.
- The device must be able to contain spillage
if the container were tipped over.
The type of device used will depend on the type
of container, and the type of waste in the container.
For containers holding liquid wastes, two styles
of funnels can be installed in the bung of an
open-top drum (5, 30, and 55 gallon). These funnels
must be kept closed and sealed when not adding
waste to the container.

For containers holding solid waste, a
self-closing lid can be used.
