Flow Test and Overhaul Requirements

The regulator and primary low-pressure warning device must be flow tested at specific time intervals
by a certified repair technician 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 this require-
ment.
Annual flow tests are a requirement of NFPA 1852, Standard on Selection, Care, and Maintenance of
Open-Circuit Self-Contained Breathing Apparatus (SCBA), 2019 edition. Although this standard
relates to SCBA used in the fire service, MSA requires that a flow test be done at least annually on all
SCBA and combination respirators that use a regulator.
MSA recommends the routine inspection of all elastomeric materials including, but not limited to,
those given in Section 4 "Visual Inspections" and Section 5 "Functional Tests".
A decision to remove apparatus from service permanently should be based on the SCBA's perfor-
mance data and whether that data meets the specified level of performance defined in the MSA CARE
manuals.
MSA recommends overhauling the SCBA after every 600 hours of on-air usage. The SCBA service
mode provides the status of on-air usage. Only trained personnel are authorized to use service mode.

15.1 Overhaul Reminder

The G1 SCBA can be configured to show an overhaul alarm on the control module after 600 hours of
on-air usage. The overhaul alarm will show on the control module during start-up every time the SCBA
is turned on until the overhaul alarm is reset. For detailed instructions about how to activate the over-
haul alarm, refer to the Operating Manual: MSA A2
(P/N 10162374).
