Which statement describes a minimum requirement for Hazardous Waste storage facilities?

• A. Be properly secured and not easily accessed by unauthorized persons.
• B. Enclosed and should not be ventilated.
• C. Have floors that are impermeable to liquids and resistant to attack by chemicals, not slippery, and constructed to retain spillages
• D. Accessible in cases of emergency and for purposes of inspection and monitoring.

Answer: (B)

The key idea here is containment to prevent exposure and spread of hazardous waste. An enclosed storage area creates a controlled space where spills, vapors, and leaks are kept within a defined boundary, which directly reduces the chance that dangerous materials reach workers or the broader environment. Saying the space should be enclosed and not ventilated emphasizes keeping releases from circulating into other areas, making it the baseline protection you want for a minimum standard.

While other features like securing access, having impermeable and chemically resistant floors, and ensuring the area is reachable in emergencies are all important safety measures, the fundamental minimum is creating a sealed environment that confines any potential releases.
