Basic Requirements for Confined Space

This section describes the basic OSHA requirements for employers with confined spaces. 

Employers with Confined Spaces

  1. Evaluate the workplace to determine if any confined spaces are permit-required confined spaces.
  2. Inform employees of these spaces by posting dander signs or other effective means that explain the existence of hazards and location of the space.
  3. If employees will not be entering the confined spaces, they need to be locked or otherwise secured.
  4. Evaluate confined spaces when the hazards change, and if necessary, reclassify as a permit required confined space.
  5. If contractors will be entering the space, work with the contractor to communicate hazards and coordinate operations.

Employers with Workers Who Enter Confined Spaces

In addition to the items listed above, workplaces that have permit-required confined space entry must also:

  1. Develop a written permit space entry program.
  2. Identify and evaluate hazards of permit spaces before they are entered.
  3. Develop procedures for entering permit spaces safely.
  4. Use an entry permit system.
  5. Evaluate permit space conditions while people are working inside the space.
  6. Train permit space entrants, attendants and supervisors on their duties and safe work practices.
  7. Provide a rescue plan and equipment.
  8. Consult with affected employees on the effectiveness of the confined space program.
