In hazardous waste disposal practices in an animal facility, who bears the primary responsibility?

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

Answer: (A)

The main idea is that the person who creates the waste is responsible for its proper management. This means they determine if the waste is hazardous, ensure it goes into the correct container, label and date it, store it safely and in the proper location, and arrange for disposal through a licensed hazardous-waste contractor. They must follow institutional policies and regulatory requirements, keep records, and report spills or improper disposal.

In an animal facility, this responsibility typically rests with the researchers or technicians who generate waste from cages, bedding, sharps, carcasses, and contaminated equipment. They’re the ones who decide how the waste should be handled at every step, from segregation to final disposal.

Custodial staff are essential for maintaining cleanliness and can assist with waste handling and cleanup, but the primary accountability for proper disposal rests with the waste generator. The environmental safety office provides the program, training, and oversight, and the biosafety committee focuses on containment and risk assessment, not daily disposal duties.
