Type 2 airlock allows movement between which areas?

• A. From unprotected area to protected area
• B. From protected area to unprotected area
• C. Between two protected areas
• D. From unprotected area to another unprotected area

Answer: (B)

Type 2 airlock is a controlled passage that sits between a protected (clean) area and an unprotected (hazardous or exposed) area. It uses an inner door and an outer door with the chamber in between, so you can move from the protected space into the unprotected space while keeping the protected area isolated. The airlock can be vented or pressurized as needed to prevent contamination or pressure changes from crossing over. In short, its primary function is to allow egress from a protected area to an unprotected area, not the other way around.
