Notes: | 1. Controlling atmospheric hazards through forced air ventilation does not eliminate the hazards. 2. The employer should evaluate the use of lockout-tagout, as covered in WAC 296-307-320, to determine if using it fully eliminates the hazard. 3. The employer is allowed to use alternate entry procedures covered in WAC 296-307-652, if the employer can demonstrate that forced air ventilation alone will control all hazards in the space. |
Note: | This certification must be completed every time a permit-required confined space is reclassified as a nonpermit space. |
