Define a permit-required confined space (PRCS).

Define a permit-required confined space (PRCS).

• A. A space with limited entry/exit but no hazards
• B. A space with potential hazards or configured to contain hazardous atmospheres that requires a permit for entry
• C. A space that is always safe
• D. A space used only for ventilation

Answer: (B)

A permit-required confined space is a confined space that has or could have hazards that may harm workers, especially the potential for a hazardous atmosphere, and therefore entry requires a formal permit and safety controls before work begins. A confined space is defined by limited entry or exit and not designed for continuous occupancy, but only spaces with hazards—or the potential for hazardous conditions—become permit-required. This is why the wording about potential hazards or a configuration to contain hazardous atmospheres is the right definition: it captures both the possibility of dangerous atmospheres and the need for documented precautions. If a space has no hazards or potential hazards, it would not automatically require a permit. A space that is always safe or one used only for ventilation doesn’t define a permit-required status on its own.
