1. INTRODUCTION
1.1 Breathable Oxygen
Oxygen used to supply or charge the
breathing apparatus must be medical or
aviation grade oxygen with moisture content
less than 50 mg/m
3
at 3000 psi (207 bar).
The composition of suitable oxygen is given
below and provides the maximum level of
contaminates in the source oxygen
acceptable for use in the BioPak.
Oxygen:
99.5%
minimum
mole
Carbon Dioxide:
300 ppm
maximum
Carbon Monoxide:
10 ppm
maximum
The purity/quality of oxygen used in the
breathing apparatus should be tested
periodically in accordance with national
regulations.
National regulations must be observed.
Personnel dealing with compressed oxygen
and compressed oxygen cylinders must be
fully trained in the use and handling of
compressed oxygen.
1.2 Apparatus Duration
The apparatus will provide the user with 440
liters of compressed oxygen and has been
rated for a 4-hour duration according to
specifications in 42CFR84. Actual duration
of the apparatus may vary due to factors
such as:
•
Workload: high work rates will
increase consumption rates of
oxygen.
•
Facemask Seal: poor seal of mask
will result in system leaks and high
consumption rates.
•
Physical Fitness of Wearer
•
System Leaks: leaks in the BioPak
system will result in high oxygen
consumption and reduced BioPak
duration.
It is important that all wearers are aware of
the above factors and take account of them
when assessing BioPak duration.
It is equally important that all wearers
understand that the BioPak 240R respirator
is a positive-pressure apparatus. Leaks in
the apparatus itself or in the seal between
the wearer’s face and the facemask will lead
to the apparatus adding additional oxygen to
maintain positive pressure.
1.3 Personnel Training
Personnel who use closed-circuit, self-
contained, positive-pressure, compressed
oxygen breathing apparatus must be fully
trained in accordance with these
instructions, local and national regulations.
These instructions cannot replace an
accredited training course provided by
qualified instructors in the proper and safe
use of
Biomarine
breathing apparatus.
