Flow Test and Overhaul Requirements

15 Flow Test and Overhaul Requirements
The regulator and primary low pressure warning device must be flow tested at specific time intervals.
These maintenance procedures must be performed by a certified repairperson or at an MSA service
center. Contact your MSA sales representative or call the MSA Customer Service Center at
1-877-MSA-3473 for more information about these requirements.
Annual flow tests are stated as a requirement in NFPA 1852, Standard on Selection, Care, and Main-
tenance of Open-Circuit Self-Contained Breathing Apparatus (SCBA), 2013 Edition, which further
emphasizes their importance. Although this standard relates to SCBA used in the fire service, MSA
requires that a flow test be performed at least annually on all fire service and non-fire service SCBA
and combination respirators that use a regulator.
MSA recommends the routine inspection of all elastomeric materials including, but not limited to those
in the Visual Inspection and Functional Check section of this manual.
A decision to retire apparatus should be based on an SCBA's performance data and whether that data
meets the specified level of performance as defined in maintenance requirements from MSA.
MSA recommends overhauling the SCBA every 600 hours of on air usage. The amount of on air
usage can be found in the service mode of the SCBA.
Overhaul Reminder
The G1 SCBA can be configured so that an overhaul alarm will appear on the control module after
600 hours of on air usage have elapsed. The overhaul alarm will appear on the control module during
startup every time the SCBA is turned on until the overhaul alarm is reset. For detailed instructions on
how to turn on the overhaul alarm, refer to the A2® Accountability Control Software Operating
Manual, 10162374.
