Which of the following defines a Permit Required Confined Space?

• A. Spaces that potentially contain a hazardous atmosphere; contains material for potential engulfment or entrapment; contains any other serious safety or health hazard
• B. Spaces easy to access with no hazards
• C. Spaces that require a permit regardless of hazards
• D. Spaces only for storage

Answer: (A)

A permit-required confined space is defined by the presence or potential of hazardous conditions that could injure someone entering. The best choice describes spaces that could have a hazardous atmosphere, could engulf or trap a worker, or have any other serious safety or health hazards. That combination is precisely what makes a confined space “permit-required” under OSHA, triggering the need for a formal entry permit, atmospheric testing, isolation, and rescue procedures before entry. In contrast, spaces that are easy to access and have no hazards are not permit-required; spaces that require a permit regardless of hazards overstate the rule; and spaces that are only for storage do not fit the definition of a permit-required confined space.
