Final answer:
Central accumulation containers should be clearly marked with the contents of the waste, indicating it is hazardous, and the accumulation start date. The chemical waste should be unused and in the form of a commercial product. Different container types and proper local disposal protocols must be considered.
Step-by-step explanation:
Central accumulation containers used for holding hazardous waste on-site need to be marked with specific information to ensure the safe handling and disposal of the waste contents. At a minimum, these containers must have markings that clearly identify the contents of the container. This typically includes the name of the chemical waste and an indication that it is hazardous. Additionally, it may also be necessary to mark the containers with the date on which waste began to be accumulated in the container. Importantly, the waste must be unused and in the form of a commercial chemical product. Containers types can vary, including high-density polyethylene, steel, or glass cylindrical containers, and may be sealed with materials such as cork stoppers. It is crucial to note that not all waste categories are accepted by all local recycling authorities, and residents should be informed about proper disposal practices to avoid contamination of the recycling stream or improper waste handling.
