durATion of The reSPirATor
The SKA-PAK AT respirator is rated and approved by NIOSH as a
combination self-contained breathing apparatus for escape and pres-
sure demand Type C supplied-air respirator.
The duration of this respirator, when used as a Type C supplied-air
respirator, is limited only by the capacity of the air-supply system.
The duration of this respirator during use as an escape only SCBA
is limited by the capacity of the self-contained air supply cylinder on
the waist belt. The cylinder's rated duration is marked on the cylinder.
The user should not expect to obtain exactly the stated duration of
breathing air during each use of the self-contained air supply cylin-
der. The user’s breathing rate may be more or less than the 40 lpm
respiration standard used in the NIOSH tests. Depending on activity
and respiration rate, the actual duration may be less than 1/2 the
rated duration of the air supply cylinder.
The length of time the self-contained air supply cylinder will continue
to provide breathing air during any one use depends on such factors
as:
1. The degree of physical activity of the user.
2. The physical condition of the user.
3. The degree to which the user's breathing is affected by excite-
ment, fear or other emotional factors.
4. The degree of training or experience the user has with this or
similar equipment.
5. Whether or not the cylinder is fully charged at the start of the use
period.
6. The possible presence in the compressed air of carbon dioxide
concentrations greater than .04% normally found in atmospheric
air.
7. The atmospheric pressure; for example, if used in a pressurized
tunnel or caisson at 2 atmospheres (15 psig gauge) the duration
will be one-half as long as when used at 1 atmosphere; and at 3
atmospheres will be one-third as long.
8. Loose or improperly fitting facepiece.
9. Whether the purge valve is open.
10. The condition of the respirator.

– Substitution of Components May Impair Intrinsic Safety. To
reduce the risk of ignition of a flammable atmosphere, batteries must only
be changed in an area known to be nonflammable. To reduce the risk of ex-
plosion, do not mix old batteries with unused batteries, or mix batteries from
different manufacturers.
The electronic end of service time indicator has not been evalu-
ated as an ignition source in explosive or flammable atmosphere
by MSHA/NIOSH.
