Which location is defined by posting personnel limits?

• A. A standard blast chamber
• B. The location where personnel limits are posted
• C. A temporary outdoor staging area
• D. A security checkpoint

Answer: (B)

The key idea is that the number of people allowed in a space is defined by a posted limit and that the location of that posted limit becomes the boundary that governs occupancy. When you see a sign or placard showing the maximum personnel for a space, that sign establishes the official limit and the area within which those limits apply. In safety practice, this makes access and staffing decisions based on where the limits are published, ensuring everyone knows how many people may be present and can be managed safely during operations, especially around hazardous activities.

Spaces like a standard blast chamber, a temporary outdoor staging area, or a security checkpoint are different in purpose or structure, but they aren’t defined by the posting itself. The sign that states the personnel limit is what defines the area’s boundary for safe occupancy and access.
