ESCAPE
Proper handling, maintenance, and other information as supplied in this manual are essential to the
effective use of the EBA-75. The user should be familiar with Instructions for Use 1-12 before
attempting to use the EBA-75.
INSTRUCTIONS FOR USE FOR USER AT REST
THE FIRST OBJECTIVE IS TO ESCAPE.
In the event escape from an oxygen deficient atmosphere cannot readily be achieved, the EBA-75
can operate for up to 6.5 hours when the user is at rest. Listed below are the steps required to extend
the oxygen supply of the EBA-75 past one hour if the unit is to be used by a man at rest. Rest is
defined as a man sitting with no activity.
(1)
Purge bag: Exhale into mouthpiece, hold breath and deflate bag by pressing on bag, then inhale
through the mouthpiece, and breathe normally.
(2)
When bag fills, close oxygen valve, clockwise.
(3)
When bag becomes low, open oxygen valve, counterclockwise.
(4)
Repeat steps 2 and 3 until no longer at rest.
Note:
Performance of the EBA-75 under the User At Rest procedure, not a requirement of 42 CFR
Part 84, Subpart O, has not been evaluated by NIOSH/MSHA.
