Principles of Operation
When used as an emergency breathing system (EBS), the ExtendAire
System enables a firefighter with depleated air supply to breathe from
the air cylinder of a fellow firefighter. By coupling the system's
40-inch rescue hose between SCBA, both firefighters can receive
intermediate pressure air for emergency escape.

The ExtendAire System also doubles as a Dual-Purpose device to allow
firefighters to quickly and easily connect to an air-line.
Approvals & Standards
An MSA MMR Air Mask equipped with the ExtendAire System is jointly
approved by the Mine Safety and Health Administration (MSHA) and the
National Institute for Occupational Safety and Health (NIOSH), and is
NFPA-compliant even when used in the Dual-Purpose mode. However,
during use of the EBS component, NIOSH/MSHA Approvals are voided, due
to the users being connected during escape. Users must excercise care
while maneuvering during escape. Failure to do so can result in
serious personal injury or death.
