What is a proper way to mark containers holding hazardous waste?

Marking containers holding hazardous waste accurately is crucial for safety and regulatory compliance. The correct approach involves using hazardous waste labels, which must clearly identify the type of waste contained within and provide necessary information regarding its hazards. This labeling is not only a legal requirement under the Resource Conservation and Recovery Act (RCRA) but also aids in ensuring that anyone who handles or comes into contact with the containers understands the risks involved and can take appropriate safety measures.

Hazardous waste labels typically include specific designations such as the accumulation start date, health hazard symbols, and the type of waste, aiding in proper handling, storage, and disposal. This systematic approach ensures that hazardous materials are managed responsibly and helps prevent accidents or contamination.

Other options may not provide sufficient clarity or details needed for the safe handling of hazardous substances, which is why they do not fulfill the necessary requirements for marking hazardous waste containers.
