Confined Space Safety

What is a confined space?

  • Confined spaces present some of the most challenging environments for health and safety professionals. From potentially toxic atmospheres, to physically hazardous conditions such as extreme temperatures, unstable materials, or the potential for falls, confined spaces often present unseen challenges. Creating and maintaining a safe jobsite with confined spaces can depend on having correct, current information.

    Confined spaces are areas that are:

    • Large enough for workers to enter and perform certain jobs AND​
    • Limited or restricted means for entry or exit AND
    • Not designed for continuous occupancy (not necessarily designed for people)

How do I plan and prepare to enter?
