Which is a basic requirement for worker entry/exit to containment areas?

• A. Authorized access
• B. Decontamination procedures
• C. Use of PPE
• D. All of the above

Answer: (D)

All of the above is the correct choice because a safe entry and exit from containment areas hinges on a complete protocol that covers who may enter, how workers clean up before leaving, and what protection they wear. Authorized access ensures that only trained personnel with the right credentials and understanding of the hazards enter the area. Decontamination procedures remove asbestos fibers from clothing, tools, and equipment so fibers aren’t carried out of the containment. Use of PPE provides protection during work inside the area and helps reduce exposure risk. Together, these elements prevent cross-contamination and minimize exposure; relying on any single measure would leave gaps—for example, access control without decontamination could spread fibers, decontamination without authorized entry could allow untrained people in, and PPE alone cannot prevent fibers from being carried out by contaminated equipment or clothing.
