Debrief: what this framework supports, and what stays local

At the bench, the first action matches the hazard: wash a needlestick, flush a chemical exposure, move away from cryogenic danger, evacuate a fire, or isolate a spill when safe. Do not delay escape from danger or urgent decontamination and first aid just to notify someone; notify as soon as it is safe.

Your local plan supplies phone trees, alarm codes, assembly points, shelter rooms, downtime procedures, spill resources, and the people who direct the broader response. Learn those site-specific actions before an event.

After the immediate response, capture the gap, assign an owner, and document what must change before routine work resumes.
