A malfunction of the PRA's primary system will automatically direct breathing air into a secondary system. When this occurs, the operating pressure will only be reduced to ___ psi and the vibralert alarm to activate. Member must notify their officer and immediately leave the contaminated area accompanied to a safe area by another member using an SCBA.
