What defines hazardous waste, and what labeling practice is required?

• A. Waste that is ignitable, corrosive, reactive, or toxic; label with waste type and hazard codes, and follow generator status rules
• B. Hazardous waste is any unused chemical; no labeling required
• C. Hazardous waste is only radioactive; label with date only
• D. Hazardous waste is determined by container color and not labeled

Answer: (A)

Hazardous waste is defined by its hazardous properties or by regulatory listing, not by what it looks like or by color. The key properties are ignitable, corrosive, reactive, or toxic. Because of these hazards, containers must be clearly labeled with the waste type and the applicable hazard codes so anyone handling it knows what it is and how to manage it safely, from storage to disposal. The labeling also follows generator status rules, which determine how long you can accumulate waste, where it can be stored, and what additional information must be on the label. So, this option reflects the proper definition and the correct labeling practices: identify the waste by its type and hazard codes and comply with generator status rules. The other ideas—calling it just any unused chemical, only radioactive waste, or judging by container color with no labeling—don’t meet how hazardous waste is defined or how it must be communicated and managed.
