A non-permit confined space by OSHA standards means a confined space that:

A non-permit confined space, according to OSHA standards, is defined primarily by the presence or absence of certain hazards. Specifically, a non-permit confined space is a location that does not contain any hazards that could pose a risk to life or health. Therefore, it is correct to conclude that a non-permit confined space is one that does not contain any hazard capable of causing death.

This indicates that there must be no potential for hazardous atmospheres, such as toxic gases or oxygen deficiency, which would typically require a permit for entry. While the other options mention specific hazards or conditions, they do not encapsulate the complete definition of a non-permit confined space as effectively as the option regarding the absence of life-threatening hazards. A space may have limited accessibility or contain materials, but if it is free from hazards that could cause death, it remains classified appropriately within OSHA’s guidelines as a non-permit confined space.
