SCBA Tip 029 (Updated  FEB 2012)
USN SCBA Configurations

Print Version PDF


 There are six SCBA configurations authorized for shipboard use.  All SCBA configurations are National Institute for Occupational Safety and Health (NIOSH) approved and National Fire Protection Association (NFPA) compliant.  Configuration changes are highlighted in red with callouts.

·         Damage Control SCBA Configuration 1

·         Damage Control SCBA Configuration 2

·         Damage Control SCBA Configuration 3

·         Damage Control SCBA Configuration 4

·         Damage Control SCBA Configuration 5

·         Damage Control SCBA Configuration 6

SCBA Configuration 1 – This is the original SCBA configuration when Fleet Modernization Program was initiated.

SCBA Configuration 2 – This configuration added of a secondary end-of-service time indicator (EOSTI) bell alarm onto configuration 1.  Configuration 1 SCBA are not required to backfit with the bell alarm.

SCBA Configuration 3 – The cylinder material was switched from fiberglass to carbon fiber for configuration 3.  This extended the periodicity of hydrostatic testing from 3 years to 5 years while reducing overall weight.  Service life of the cylinder remains unchanged at 15 years

SCBA Configuration 4 – Multiple changes occurred with configuration 4 over older models.  First, the secondary end-of-service time indicator switched from bell alarm to a visual Heads-up Display (HUD) of relative cylinder pressure remaining.  This SCBA configuration is NIOSH approved for Chemical, Biological, Radiological, and Nuclear (CBRN) and can be distinguished by the red background label on the mask mounted regulator (prior configurations had white background).  This configuration also consolidated the quick charge connection previously found on the quick charge adapter into the RIC UAC connection near the cylinder valve.  Finally, the AV2000 facepiece was replaced by the AV3000 with Kevlar head harness.

SCBA Configuration 5 – Changes that occurred for configuration 5 are minor compared to the prior configuration changes.  The main difference is the visualert electronics that drives the HUD was moved from the primary pressure reducer and consolidated into a console with the remote pressure indicator on the wearer’s right shoulder strap.  The voice amplifier model changed to the epic voice ampand the AV3000 facepiece has an improved nose cup design (grey in color). Finally, the HUD also includes a light sensor to reduce HUD brightness in low light conditions.

SCBA Configuration 6 – The major changes in the latest configuration are the carbon fiber cylinder service life changed from 15 years to 30 years. The cylinder band is replaced with a Kevlar strap and the wireframe is changed to stainless steel.  There are also minor changes to hose routing through the back frame.
