Flow Test And Overhaul Requirements - MSA FireHawk M7 Responder Operation And Instructions Manual

FLOW TEST AND OVERHAUL REQUIREMENTS

FLOW TEST AND OVERHAUL REQUIREMENTS
The Firehawk Responder Regulator and Audi-Larm Alarm
must be flow tested and overhauled at specific time inter-
vals. These Maintenance Procedures must be performed
by a trained repairperson or at a certified service center.
Contact your MSA sales representative or call the MSA
Customer Service Center at 1-877-MSA-3473. They will
supply the information needed to meet these require-
ments.
Annual flow tests are stated as a requirement in NFPA
1852, Standard on Selection, Care, and Maintenance of
Open-Circuit Self-Contained Breathing pparatus (SCB ),
2002 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 pressure demand
regulator.
Average Air Mask Usage
1 cylinder per day or greater
1 cylinder every other day
1 cylinder per week or less
*The unit of air mask use is defined as the consumption of one entire cylinder of air. Example: If three cylinders of air are
used, the air mask would be considered to have been used three times.

The required replacement/overhaul schedule for MSA air
masks is based on apparatus usage on an individual
basis. The frequency required for air mask overhaul
depends upon how often the apparatus is used. MSA air
masks must be overhauled based on the actual level of
usage of the air mask, rather than on time alone.
MSA air masks must be flow tested every year using an
MSA approved flow test device. The table below summa-
rizes MSA's required frequency for overhaul and flow
testing.
A decision to retire apparatus should be based on an air
mask's performance data and whether that data meets
the specified level of performance as defined in mainte-
nance requirements from MSA.
If an assessment of the air mask's usage cannot be esti-
mated or determined, then the air mask shall be over-
hauled every three years.
