Emergency Rescue and Toxic Atmospheres
An Unprotected Rescuer Can Become the Next Casualty
When someone collapses near a tank, vessel, drain, pit or chemical work area, the instinct to rush in can expose more people to the same invisible hazard. A rescue must begin with alarm, hazard recognition and the approved emergency response—not an unplanned entry. Protecting the rescuer is part of protecting the casualty, because a second collapse delays the competent response and increases the number of people in danger.
Controls to confirm
- Stop nearby work, raise the site alarm immediately and keep unprotected people outside the suspected hazard area while providing the location, task and known substances to the emergency team.
- Do not enter a suspected toxic or oxygen-deficient atmosphere unless the approved rescue plan is activated and authorised responders have suitable respiratory protection, monitoring, communications and backup.
- Isolate or stop the source only when this can be done from a safe location by an authorised person, then preserve access for responders and follow their instructions until the area is formally declared safe.
Today’s action
Before the first chemical, tank, drain or confined-space task today, ask the work party to point out the alarm method, safe waiting position and approved rescue route.
