WAC 296-307-65404. Reevaluate nonpermit confined spaces if hazards develop

(1) The employer must reclassify a nonpermit confined space to a permit-required confined space, if necessary, when changes in the use or configuration of the space increase the hazards to entrants . (2) The employer must make sure all employees exit the space if hazards develop. The employer must then reevaluate the space and determine whether it must be reclassified as a permit-required confined space.
