Which statement best describes a confined space?

• A. A confined space has a limited number of exits, is large enough to enter & perform work, and is not designed for continual occupancy.
• B. A confined space has multiple exits and is not large enough to enter
• C. A confined space is always well-ventilated
• D. A confined space is never hazardous

Answer: (A)

A confined space is defined by restricted means of entry and exit and by not being designed for regular, continual occupancy. It must be just large enough for a person to fit inside and perform work, but it isn’t meant for people to stay in for long periods. That combination is what the best description captures: a space with a limited number of exits, large enough to enter and work, and not designed for continual occupancy. Ventilation quality or whether hazards are present do not define a confined space, and spaces with multiple exits can still be confined if access is restricted and not intended for ongoing occupancy.
