A supervisor wants to skip the full permit process for a sewer entry by claiming the space is 'reclassified' as non-permit. Under Cal/OSHA, when is such reclassification allowed?
a.Anytime, if the crew is experienced
b.Only if the space has never had a problem before
c.Whenever the customer signs a waiver
d.Only after testing and inspection show all serious hazards are eliminated, not merely controlled
Giải thích
Under Title 8 §5157, a permit space may be reclassified to non-permit only when all atmospheric and other serious hazards are actually eliminated (not just controlled by continuous ventilation) and testing plus inspection confirm it. If a hazardous atmosphere could return, or the hazard is only controlled by ventilation, the space stays permit-required. Reclassifying to dodge safeguards is a serious violation.
