Appropriate Containers for Dangerous Waste
Containers and Container Management
Select a container made of material compatible with the waste. For example, use
polyethylene containers rather than metal drums for corrosive wastes. Containers designed for food are not appropriate for chemical wastes.
The container must be:
- Intact, with no holes or corrosion
- Safe for workers
- Labeled correctly
If a waste is a powder, the material should not be able to sift out during
transport.
Label Waste describes labeling requirements.
Empty Containers
addresses the legal definition of "empty" and how to handle empty
containers.
Container Management
Keep containers of dangerous waste in a dangerous-waste-accumulation area.
Container rows should be 30 inches apart to allow for easy inspection. Keep incompatible wastes apart. Separate them by a dike, berm
or wall adequate to prevent mixing in case of leaks.
Keep dangerous waste containers closed, except when adding or removing waste. Keep
containers covered and out of the weather.
Funnels must screw in tightly. Lock all funnels and securely fasten ring
locks. Remove any non-locking funnels.
Storage and Accumulation discusses
storage time limits.
Satellite Accumulation allows some waste
to be stored near the point of generation.
Secondary Containment
offers suggestions for how to contain liquid dangerous wastes.
Check containers and the entire system at least once a week for leaks, rust,
dents, or other defects. Transfer waste out of unsafe containers. Keep
Good Records of these inspections.
Spills discusses preparedness and
responsibility for spills.
How to Report a Spill explains your notification requirements when
a spill or a severely leaking
or rusting container releases dangerous waste into the environment.
You must immediately notify the Department of Ecology and appropriate local
agencies.
