Washington's safety rules for confined spaces in general industry workplaces mirror federal rules (WAC 296-809-100 to 296-809-800), and the state has adopted requirements that are stricter than federal rules for the written confined space permit program, and for alternate entry procedures for spaces with a hazardous atmosphere.
The Washington Department of Labor and Industries (DLI) administers and enforces workplace safety and health rules.
WRITTEN PERMIT-REQUIRED CONFINED SPACE PROGRAM
In addition to identifying the safety procedures and equipment to protect workers from the hazards of permit spaces, the written program must include, where applicable:
ALTERNATE ENTRY PROCEDURES
- Documentation of permit entry procedures
- Documentation used for alternate entry procedures
- How to reclassify permit-required confined spaces to nonpermit spaces
- Designation of employee roles, such as entrants, attendants, entry supervisors, rescuers, or those who test or monitor the atmosphere in a permit-required space
- Identification of designated employee duties
- Training employees on their designated roles
- How to identify and evaluate hazards
- Use and maintenance of equipment
- How to prevent unauthorized entry
- How to coordinate entry with another employer
- How to rescue entrants
When using alternate entry procedures instead of permit entry procedures, and if a hazardous atmosphere is detected during entry, comply with the federal procedures and the following state-specific requirements:
- Implement measures to protect employees from the hazardous atmosphere before continuing the entry operation.
- Verify the space is safe for entry before continuing the entry operation.
