1. Two

2. Three

3. Four

4. Five

The correct answer is: Three

A decontamination unit, as required by OSHA for asbestos abatement, consists of three rooms connected in series. This configuration is crucial for effectively managing the decontamination process and ensuring that hazardous materials are contained and properly managed. The first room is typically used for the removal of contaminated clothing and equipment. This is where workers can take off their personal protective equipment (PPE) and any clothing that may have come into contact with asbestos, helping to minimize the spread of contaminants. The second room serves as the shower area, where workers can wash off any remaining asbestos fibers from their bodies. This room is vital for ensuring all potential contaminants are removed before individuals exit the decontamination area. The third room functions as the clean change area, allowing workers to put on clean clothing and gear before leaving the decontamination unit. This ensures that no asbestos fibers are carried out into uncontaminated areas. The tripartite design of the decontamination unit is essential for protecting both the workers and the environment from asbestos exposure. By including these three distinct zones, OSHA standards aim to provide comprehensive decontamination and safeguard public health.
