In an emergency involving smoke or chemical exposure, what is the first action to taken with an SCSR?

In an emergency involving smoke or chemical exposure, the first action to take with a Self-Contained Self-Rescuer (SCSR) is to activate and don the device. The immediate use of the SCSR is crucial because it provides a source of breathable air, allowing the user to protect themselves from toxic smoke and harmful chemicals. Quick access to clean air significantly increases the chances of survival and safety in a hazardous environment, especially since visibility and breathing can quickly deteriorate.

Activating and properly wearing the SCSR ensures that the individual is ready to move to a safer location without being incapacitated by the dangers present. While alerting nearby workers, assessing the environment, and calling for help are important considerations in an emergency response, they should occur after securing personal safety with the SCSR. This prioritization of personal safety is vital in ensuring that the individual can effectively assist others afterward or navigate to safety without further exposure to hazardous conditions.
