| Note: | • Controlling atmospheric hazards through forced air ventilation does not eliminate the hazards. |
| • You should evaluate the use of lockout-tagout, as covered in chapter 296-803 WAC, to determine if using it fully eliminates the hazard. | |
| • You are allowed to use alternate entry procedures covered in WAC 296-809-600, if you 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. |
