What is a Confined Space?

Environments that require the use of confined space gear have various defining features. These tight areas offer little room to move and have very few passages through which a worker can enter or leave. The space is also not well-ventilated, likely resulting in the presence of hazardous airborne contaminants. As such, these kinds of atmospheres are not hospitable to workers, and therefore work done within such areas should be brief and intermittent.

Some examples of confined spaces are:

  • Boilers
  • Ship compartments
  • Storage tanks
  • Tunnels
  • Sewers

For more information on confined spaces, visit the Centers for Disease Control and Prevention.
