What should a user do during an SCBA malfunction in an emergency?

In the event of an SCBA malfunction during an emergency, the appropriate course of action is to exit the hazardous area and switch to a backup SCBA. This action ensures the user's safety by prioritizing immediate removal from the dangerous environment where compromised breathing apparatus could lead to inhalation of hazardous substances.

Exiting the area minimizes exposure to toxic gases or smoke and allows the user to regain control of their breathing by utilizing a properly functioning SCBA. The availability of a backup SCBA is a critical component of emergency preparedness, allowing for a quick response to gear failures without delaying or jeopardizing the safety of the individual.

This response is essential not just for the individual's immediate health and safety, but also to maintain situational awareness during high-stress scenarios, enabling them to focus on reaching a safe location without further complications.
