What containers must be used?

• A facility can store several different hazardous wastes in the same container, as long as the wastes are compatible with each other.

There are no requirements as to specific storage containers to be used, as long as the container is compatible with the hazardous waste put in it. In other words, do not put a substance that is reactive with metal in a metal container.

A facility can store several different hazardous wastes in the same container, as long as the wastes are compatible with each other. If a company is using several different solvents, the company can store them all together in one drum if they don’t react with each other. However, there are economic reasons why this mixing of different wastes may not always be a good idea.

A facility can store hazardous waste in 55-gallon drums, tanks, or other containers suitable for the type of waste generated if the facility follows certain commonsense rules that are meant to protect human health and the environment and reduces the possibility of damages or injuries caused by leaks or spills of hazardous wastes.

Owners and operators of all hazardous waste facilities that store containers of hazardous wastes must ensure the following:

• All containers are in good condition and are not leaking; if the container begins to leak, transfer the waste from the leaking container to a container that is in good condition or otherwise manage the waste to meet the regulations at 40 CFR Parts 264 and 265.
• Owners and operators must make sure the lining of the container is compatible with the materials that will be stored in it; the lining must not react with the waste to be stored.
• Store containers of incompatible wastes apart from each other.
• The container must always be closed — except during times of adding or removing waste.
• The container must not be opened, handled, or stored in any way that would cause it to rupture or leak.
• Owners and operators must inspect areas where the containers are stored at least once per week, looking for leaks and deterioration caused by corrosion or other factors.
• Ensure that if a facility is storing ignitable or reactive wastes, the containers are placed as far as possible from the facility property line to create a buffer zone. Large quantity generators (LQGs) must store ignitable or reactive wastes at least 50 feet away from the property line.
• Never store wastes in the same container that could react together to cause fires, explosions, leaks, or other releases.
