Name three classes of hazardous waste and a BEA-specific handling principle.

• A. Acute hazardous waste, toxic waste, corrosive waste; segregate, label, and store per regulations; use secondary containment
• B. Biological waste, chemical waste, inert waste; store anywhere
• C. Radioactive waste, incinerable waste, recyclable waste; mix before disposal
• D. Solid waste, liquid waste, gas waste; dispose in regular trash

Answer: (A)

Understanding how hazardous waste is categorized and handled helps you see why this option fits best. Hazardous waste is grouped by the type of danger it poses: acute hazardous waste presents immediate danger to health or the environment, toxic waste is poisonous and can cause long-term harm, and corrosive waste can damage skin, eyes, or materials and often reacts with other substances. In a BEA setting, the handling principle emphasizes keeping wastes separate by type (segregation) to prevent dangerous interactions, clearly labeling every container so everyone knows what it is and what hazards it carries, and storing wastes in designated areas with secondary containment to catch leaks or spills. This combination helps ensure safe storage, regulatory compliance, and quick response if something goes wrong.

The other options don’t fit because they either groups wastes in nonstandard or inappropriate categories (for example, biological, inert, or a broad “solid, liquid, gas” framing) or suggest unsafe practices (storing anywhere, mixing before disposal, or disposing of hazardous wastes in regular trash).
