Potential impact of a 2-person security rule on BioSafety Level 4 laboratory workers

Area of Science:

• Biosafety and Biocontainment
• Laboratory Security
• Public Health

Background:

• Major US BioSafety Level 4 (BSL-4) laboratory directors convened in 2008.
• Discussions focused on biocontainment operations and a proposed two-person security rule.

Purpose of the Study:

• To review the current status of BSL-4 laboratory operations.
• To evaluate the potential impact of a mandatory two-person security rule.
• To determine the most effective security and safety measures for maximum-containment laboratories.

Main Methods:

• Consensus-building among BSL-4 laboratory directors.
• Discussion and risk-benefit analysis of a two-person security rule versus alternative monitoring systems.
• Evaluation of efficiency, economy, pathogen manipulation assurance, and safety.

Main Results:

• A consensus favored video monitoring systems over the two-person rule.
• Video monitoring was deemed more efficient and economical.
• Enhanced assurance of proper pathogen manipulation and increased employee safety and security were noted.

Conclusions:

• Video monitoring systems offer a superior standard for BSL-4 laboratory operations.
• The two-person rule may introduce undue pressure and unnecessary risks.
• Alternative security measures should prioritize efficiency, safety, and effective containment.
