Which term describes spaces that require a permit to enter?

• A. Open space
• B. Non-permit required
• C. Restricted area
• D. Permit-required confined space

Answer: (D)

Permit-required confined space is the term used for spaces that require a permit to enter because they have or could have hazards that make entry dangerous. These spaces are large enough to work in but have limited or restricted means of entry and exit, and they may contain toxic or flammable atmospheres, lack of oxygen, engulfment hazards, or other physical dangers. Using a permit system ensures proper safety steps before entry—isolating energy sources, testing and monitoring the atmosphere, ventilating as needed, using appropriate PPE, and having a trained attendant and rescue plan ready. In plumbing work, examples include sewer lines, manholes, septic tanks, sumps, and underground vaults, where hazardous conditions can develop or exist. Other terms describe areas that aren’t governed by this permit process — open spaces aren’t confined; non-permit required spaces lack the hazards that trigger the permit; restricted areas are about access control rather than hazard-based entry permits.
