Documentation
MSA recommends keeping a file for each device where the serial numbers, the dates of manufacture
and the dates and results of the inspections are recorded.
WARNING
The product must be inspected per the instructions of this section and removed from service if it does
not pass the inspection. Use of product that has not passed inspection may result in
over-pressurization of the product, an ignition danger or other condition thereby seriously
compromising the user's life.
National regulation must be observed, e.g. control interval according German Mining
Regulation.
User specific conditions may require shorter intervals.
The service life depends on the type and kind of treatment to which the device were
subjected.
The intervals below apply for devices used in a single shift operation of 8 hours during
a normal work week of 5 days. Increased use requires the intervals to be shortened.
For example, working in a double shift (2 x 8 hours per day and 5 days per week)
will reduce the expected lifetime by 50% to 5 years.
Intervals
1
1 The intervals are based on the date of manufacture [month/year] on the container.
Devices manufactured in the same year are considered as "population" and should be
combined for inspection.
Inspection
Before and after carrying
External visual check:
Check, that the seal is intact and that there are no external damages
on the device.
Damage includes dents, deformations and signs of heat, but is not
limited to. If any damage is found, immediately remove the unit from
service
for further investigation by qualified personnel
.

2 Perform the tightness check every 6 months for all devices used more than in a
single shift operation.
3 Perform a complete check of 2% of the population after 1 year, for devices exposed to
high mechanical stress, sustained vibration and/or elevated temperature (e.g. stored
next to engines).

6 If the inventory of devices is less than ten devices the inspection after 3 years is not
necessary. A complete inspection of the whole inventory of devices is necessary after
5 years.
