The first ninety seconds

A phlebotomist finishes a routine coagulation draw and is engaging the needle's safety shield when the needle slips and punctures the left index finger through the glove. No blood is visible on the outer glove surface; a small puncture with minor bleeding is present. The tube is already in the collection tray. Nothing else in the room has changed: no alarm, no spill, no fire. The only unusual thing is what just happened to one person's hand.

This is an exposure incident under the bloodborne pathogens standard: contact with blood or other potentially infectious material (OPIM) through the eye, mouth, mucous membrane, non-intact skin, or a parenteral route such as a needlestick or cut. The definition does not depend on whether the source patient is known to carry an infection, and it does not depend on how much blood was involved. It depends on the route.

The first moves depend on the hazard. Escape immediate danger or begin urgent decontamination or first aid before notification when delay would worsen harm; notify as soon as it is safe. A needlestick, splash, cryogenic contact, fire, spill, outage, and security event do not share one rigid sequence.

This is not a clinical judgment call: a laboratory professional does not diagnose infection risk, stage a burn, or decide whether a fire is survivable. The task is to recognize the hazard category in front of them, take the correct immediate action, and know who to notify and what gets documented, so that everything after those first minutes, testing continuity, medical follow-up, incident command, happens on the timeline the guidance and the local plan expect.

The first job in any laboratory emergency is protecting people and starting notification; deciding what it means for the specimen, the analyzer, or the shift comes after that, not instead of it.
