Which statement describes a Non Permit Confined Space?

• A. Contains no hazardous atmosphere or serious safety hazard, and workers will not perform work that could cause a hazard.
• B. May contain hazards that could cause a hazard.
• C. Is IDLH hazard.
• D. Is large enough to enter.

Answer: (A)

The main idea here is how to tell apart permit-required confined spaces from those that don’t need a permit. A non-permit confined space is one that is still a confined space (limited entry or exit, not designed for regular occupancy) but does not contain a hazardous atmosphere and does not have any other serious hazards that would require a permit.

So the statement that describes a non-permit confined space is that it contains no hazardous atmosphere or serious safety hazard, and workers will not perform work that could cause a hazard. That captures both the absence of hazards and the fact that the planned work won’t create conditions needing a permit.

Why the others don’t fit: simply being large enough to enter is a property of many confined spaces, but size alone doesn’t determine permit status. A space with an IDLH (extremely dangerous) condition clearly requires special precautions and a permit. If a space may contain hazards that could cause harm, it falls under permit-required criteria.
