Which of the following is not a trait of a confined space?

A confined space is defined by several specific characteristics that help determine the safety and accessibility of that area for employees. One of the key traits is that it must be large enough for a person to enter and perform work, which actually aligns with the definition of a confined space. The other options describe conditions that may pertain to hazardous confined spaces, such as having an oxygen-deficient atmosphere or limited means of entry and exit, and being unsuitable for continuous occupancy.

A confined space is not meant to be a permanent workspace for employees, hence the aspect of it not being designed for continuous employee occupancy. Understanding the correct characteristics of confined spaces is critical for safety protocols and ensuring that proper precautions are taken when entering such areas. Therefore, option A, while apparently stating a trait, actually reflects a fundamental necessity of a confined space, making it incorrect in this context.
