FLOW TEST AND OVERHAUL REQUIREMENTS
FLOW TEST AND OVERHAUL REQUIREMENTS
The air mask Regulator and alarm must be flow tested
and overhauled at specific time intervals. 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 1-800-MSA-2222. They will supply the
information you need to meet these requirements.
The required replacement/overhaul schedule for self-
contained breathing apparatus from MSA 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 breathing apparatus must be
overhauled based on the actual level of usage, rather than
on time alone.
Overhaul is covered in the Regulator Disassembly and
Repair sections and includes installation of the Regulator
overhaul kits.
MSA breathing apparatus must be flow tested every year
using an MSA approved flow test device.

The following table summarizes MSA's required frequency
for overhaul and flow testing.
Average
Air Mask Usage* Overhaul Frequency
1 cylinder per Every 3 years
day or greater
1 cylinder every Every 8 years
other day
1 cylinder per Every 15 years
week or less
*A decision to retire an air mask should be based on an
air mask's performance data and whether that data meets
the specified level of performance as defined in
maintenance requirements from MSA.
*The unit of air mask use is defined as the consumption of
one 30 min. cylinder of air. Example: If three cylinders of
air are used, the air mask would be considered to have
been used three times. If an assessment of an air mask's
usage cannot be estimated or determined, then the air
mask shall be overhauled every three years.
