In BE, which statements best describes biosafety containment for biological hazards?

• A. Higher biosafety containment, sterile technique, and specialized PPE and facilities.
• B. No special containment is needed beyond gloves.
• C. Only signage is required.
• D. Biological hazards are managed with general housekeeping alone.

Answer: (A)

Biosafety containment for biological hazards relies on layered protections that combine engineering controls, procedural practices, and personal protective equipment. The best description emphasizes using higher biosafety containment appropriate to the hazard, along with sterile technique and specialized PPE and facilities. This means you don’t just rely on gloves or signs; you implement appropriate containment levels (such as properly equipped rooms or cabinets that control aerosols and exposures), apply aseptic or sterile techniques to prevent contamination, and use PPE matched to the risk (gloves, gowns, eye protection, respirators when needed). These elements work together to prevent both exposure to workers and release to the environment. Options that mention only gloves, or signage, or general housekeeping, don’t provide the necessary combination of containment, engineering controls, and procedural discipline required for safe handling of biological hazards.
