Principles of Operation
MSA’s ExtendAire Systems are Emergency Breathing Supply System (EBSS) accessories that use intermediate pressure air
to provide firefighters with a source of
emergency breathing air. The ExtendAire system allows firefighters to
quickly and easily connect to and breathe from a fellow firefighter’s air
cylinder. ExtendAire Systems are tightly integrated with the SCBA to provide unrestricted mobility and easy access
during critical situations. The system uses a quick connect with an integrated check valve that prevents the
breathing air pathway from being contaminated by ambient air.The ExtendAire I System is integrated to the FireHawk® Second Stage Regulator’s intermediate pressure line. Coupling the system's 40-inch rescue hose between SCBA, provides both firefighters with intermediate pressure air for emergency escape. MSA’s new ExtendAire II System offers an integrated rescue hose used with the PR14™ First-Stage Regulator that features both male and female quick-connect fittings. The system is stowed in a waist pouch that mounts on the carrier assembly and is designed to prevent snagging and accidental opening. The ExtendAire II System also connects to the ExtendAire I System for additional system flexibility. Approvals & Standards This air mask
is approved by the National Institute for Occupational Safety and Health
(NIOSH) and is NFPA-compliant without interconnection of two users to one
apparatus. NIOSH does not certify respirators for use as buddy breathers;
therefore, attachment of a donor’s emergency breathing hose to a receiver’s
emergency breathing hose voids NIOSH/MSHA approvals for both apparatus. Users
must exercise care while maneuvering during escape; failure to do so can result
in serious personal injury or death.
