Wastes can be stored in fume hoods or near the sink.

• A. True
• B. False
• C. Not sure
• D. Not applicable

Answer: (B)

Wastes should be stored only in designated waste containers within a proper waste storage area, not in fume hoods or near the sink. Fume hoods are built to exhaust volatile vapors from active experiments, not to hold waste. Placing waste inside a hood can obstruct airflow, complicate containment, and increase the risk of vapors escaping or leaking when containers are moved or when airflow changes. Storing waste near the sink creates chances of spills, splashes, or drainage contamination, and it can lead to reactions if incompatible wastes come into contact with water or are flushed improperly. For safety and regulatory reasons, hazardous waste must be kept in clearly labeled, closed containers with secondary containment in an approved storage area, away from drains, ignition sources, and areas of active work.
