Biosafety Level 3 includes:
a. Double sets of entry doors
b. Pressurized suits
c. Showers in entryways
d. All of the above

검증된 단계별 안내

Understand that Biosafety Levels (BSL) are a series of protections designed to contain infectious agents in laboratory settings, ranging from BSL-1 (lowest risk) to BSL-4 (highest risk).

Recall that BSL-3 laboratories are designed to work with pathogens that can cause serious or potentially lethal diseases through inhalation, requiring specific engineering and procedural controls.

Identify the typical features of BSL-3, which include controlled access, directional airflow, and specialized personal protective equipment, but do not usually require pressurized suits or showers in entryways.

Recognize that double sets of entry doors are a common feature of BSL-3 labs to maintain containment and prevent contamination.

Conclude that among the options given, only 'double sets of entry doors' correctly describe a BSL-3 feature, while pressurized suits and showers in entryways are more characteristic of BSL-4 facilities.

Biosafety Levels (BSL)

Biosafety Levels are a series of protections designed to contain infectious agents in laboratories. They range from BSL-1 (lowest risk) to BSL-4 (highest risk), with each level requiring specific safety practices, equipment, and facility design to prevent exposure.

Features of Biosafety Level 3 (BSL-3)

BSL-3 labs handle pathogens that can cause serious or potentially lethal diseases via inhalation. Key features include controlled access, double-door entry, directional airflow, and specialized personal protective equipment, but do not typically require pressurized suits or mandatory showers.

Personal Protective Equipment (PPE) and Facility Requirements

PPE and facility design vary by biosafety level. While BSL-3 requires respiratory protection and controlled access, pressurized suits and mandatory showers are characteristic of BSL-4 labs, which handle the most dangerous pathogens.
