Giải thích
Cal/OSHA hot-work rules require appropriate fire-extinguishing equipment, such as a suitable portable fire extinguisher or charged hose, to be present and ready for instant use whenever open-flame or spark-producing work is done. The equipment must match the likely fire type and be maintained. Having it steps away, not across the building, can stop a small ignition from becoming a structure fire.
