Controlled access to the lab environment is a notable practice in biosafety level 3 laboratories because it helps to minimize the risk of exposure to potentially harmful pathogens. In these laboratories, strict access control measures are implemented to ensure that only authorized personnel who have received specialized training are allowed entry. This reduces the likelihood of accidental exposure and maintains a secure environment for working with infectious agents that may cause serious or potentially lethal diseases upon exposure.

In addition to controlled access, biosafety level 3 laboratories make use of various safety equipment and protocols to further protect both the workers and the surrounding environment. Such measures include the use of personal protective equipment (PPE), biological safety cabinets, and specific waste disposal procedures that adhere to regulatory requirements, all of which contribute to a high level of biosafety.
