Which term describes confined spaces that cannot contain any hazard that may cause death or serious physical harm?

Which term describes confined spaces that cannot contain any hazard that may cause death or serious physical harm?

• A. Non-permit
• B. Permit-required
• C. Hazardous
• D. Confined

Answer: (A)

This question tests understanding of how confined spaces are classified by permit requirements. If a space contains or could contain hazards that could cause death or serious physical harm, it is a permit-required confined space and requires an entry permit and specific safety controls. If a space cannot contain any hazard of that level, it does not require a permit; it's called a non-permit confined space. Therefore, the term describing spaces that cannot contain any hazard is non-permit. Other terms don’t fit this classification: permit-required describes spaces with hazards that need a permit; hazardous isn’t a formal space-typing term; confined describes a space’s size/entry but not its hazard or permit status.
