Final answer:
A self-closing door with locks is not required for a Biosafety Level 1 (BSL-1) lab as they handle agents that do not cause disease in healthy humans.
Step-by-step explanation:
False. A self-closing door with locks is not required for a Biosafety Level 1 (BSL-1) lab. BSL-1 laboratories involve minimal risk to lab workers and the environment as they handle agents that do not cause disease in healthy humans. Agents classified as BSL-1 include well-characterized organisms such as nonpathogenic strains of E. coli and Bacillus subtilis. BSL-1 labs may still have safety precautions in place, such as biohazard warning signage on doors and lab areas where agents are handled, and access restrictions.
