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.
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 part, while being addressed for a specific application in another rule. When this happens, both requirements apply and should not 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 and industries (L&I) office.
