Open bench work at ABSL-1 is permissible under which condition?

• A. Good microbiological techniques
• B. No special techniques required
• C. Biosafety cabinet must be used
• D. PPE alone is sufficient

Answer: (A)

Open bench work at ABSL-1 is allowed as long as you follow good microbiological techniques. At this level, the organisms are not known to cause disease in healthy people, so containment relies on standard practices rather than special containment equipment. The emphasis is on preventing contamination and exposure through proper handling, hygiene, and disinfection—things like not eating or drinking in the area, practicing proper hand hygiene, keeping work surfaces clean, using sterile techniques when handling cultures, and disposing of materials safely according to protocol. PPE such as a lab coat and gloves are used as part of the protection plan, but PPE alone isn’t enough—the procedures themselves and the maintenance of a clean, controlled work environment are essential. A biosafety cabinet isn’t routinely required for ABSL-1 unless a procedure generates aerosols or poses a higher risk, which is a condition more typical of higher containment levels.
