Definition:

A confined space is a space that is all of the following:

- Large enough and arranged so an employee could fully enter the space and work.
- Has limited or restricted entry or exit. Examples of spaces with limited or restricted entry are tanks, vessels, silos, storage bins, hoppers, vaults, excavations, and pits.
- Not primarily designed for human occupancy.

Rules in Other Chapters that Cover Confined Spaces
Rules in other chapters that cover confined spaces may also apply to your work. You can find a list of these rules in the Resources section of this chapter.

Note:

  • Requirements in other chapters may apply to your work. You will find some safety and health requirements are addressed on a broad level in this chapter, while being addressed for a specific application in another rule. When this happens, both requirements apply and shouldn't conflict. When a conflict does occur, you need to follow the more specific requirement.
  • If you are uncertain which requirements to follow, contact your local Labor & Industries (L&I) office.
  • For a complete list of local L&I offices, see the Resources section of the Safety and Health Core Rules, chapter 296-800 WAC.
