Which of the following is included but not limited to confined spaces?

Confined spaces are defined as areas that are large enough for a worker to enter and perform tasks but have limited means of entry or exit and are not designed for continuous occupancy. The correct answer encompasses various types of enclosed spaces, including vessels, tanks, vaults, and more.

Vessels are structures such as pipes or boilers that may require maintenance or inspection, and they often have specific entry and exit challenges. Tanks, which might hold liquids or gases, also pose confined space issues due to their design and accessibility. Vaults, typically used for storage or safety reasons, can create hazardous situations for individuals entering them without proper training or equipment.

The phrase "included but not limited to" acknowledges that while these specific types of spaces are recognized as confined spaces, there are many other examples not listed. Therefore, knowing that all these structures fall within the definition of confined spaces reinforces the importance of recognizing the hazards associated with any such area. Understanding the variety of environments classified as confined spaces is essential for proper safety precautions and training measures.
