Containers for accumulating unwanted hazardous materials must be of good quality and compatible with the waste being collected. Examples of unsuitable containers are food containers, such as milk jugs and soft drink bottles, and the use of metal containers for acidic materials. The use of metal safety cans for accumulating halogenated solvents is sometimes overlooked; this practice is unacceptable because halogenated solvents can dissociate to produce acids, which in turn corrode metal.
All containers holding liquids must have a screw-top cap.
Leftover hazardous materials in original containers do not need to be transferred to another container for disposal unless the original container has deteriorated to the point that spills are likely.
Plastic or plastic-coated glass containers are preferred due to potential breakage hazards of glass containers. However, EHS has no plans to prohibit the use of glass containers for collection of unwanted hazardous materials. EHS generally discourages the use of metal cans for accumulation of unwanted hazardous materials.
