In the animal facility, who has the primary responsibility for the safe handling and disposal of hazardous waste?

• A. The individuals whose activities created the waste
• B. The custodial staff
• C. The environmental safety office
• D. The biosafety committee

Answer: (A)

The person who creates the waste is the one primarily responsible for handling it safely and arranging disposal. In an animal facility, that means the technician, researcher, or staff member whose activities generate the waste must identify its hazards, segregate it properly, and package it in compatible, labeled containers according to institutional policies and regulatory requirements. They should date and label contents, ensure containers are leakproof and in the correct designated storage area, and initiate the pickup process or disposal workflow, while documenting any spills or deviations and keeping training current. Others—custodial staff, the environmental safety office, and committees—play important support and oversight roles, but the generator bears the day-to-day accountability for safe handling and disposal.
