Confined Space Program

The permit space program must establish a system for preparing, using, and canceling entry permits, which are written or printed documents that allow and control entry into permit spaces. A key provision of the program is that a competent person must evaluate and identify permit spaces.

A competent person must evaluate the work site and identify confined spaces.

A permit space program must:

  • Implement measures to prevent unauthorized entry;
  • Identify and evaluate permit space hazards before allowing employee entry;
  • Provide for the atmospheric conditions in the permit space to be tested before entry operations and for the space to be monitored during entry;
  • Require appropriate testing for the following atmospheric hazards in this sequence: oxygen, combustible gases or vapors, and toxic gases or vapors;
  • Establish and implement the means, procedures and practices to eliminate or control hazards necessary for safe permit space entry operations;
  • Identify employee job duties;
  • Provide and maintain, at no cost to the employee, personal protective equipment and any other equipment necessary for safe entry, and require employees to use the equipment properly;
  • Ensure that at least one attendant is stationed outside the permit space during entry operations;
  • Implement the procedures that any attendant who is required to monitor multiple spaces will follow during an emergency in one or more of those spaces;
  • Coordinate entry operations (in consultation with the controlling contractor) when employees of more than one employer are working in the permit space; and
  • Establish procedures for summoning rescue and emergency services and preventing unauthorized personnel from attempting rescue.
