What is the main, easiest way to identify a confined space?

• A. Whether or not an operator can enter while standing upright
• B. By what surrounds the space
• C. By the space's function
• D. Checking on a plant or site map

Answer: (A)

The easiest way to tell is by entry capability. Confined spaces are those with limited or restricted means for entry or exit and are not designed for continuous occupancy. If you can enter a space while standing upright, you typically aren’t dealing with a confined space. If you must crawl, twist, squeeze through a small opening, or use special equipment to enter, that indicates restricted entry and points to a confined space. Surrounded by anything or the space’s function can help describe it, but they don’t define whether entry is restricted. A plant or site map alone doesn’t determine confinement, since it doesn’t show how easy it is to enter or exit.
