INSPECTION AND MAINTENANCE
Inspection guidelines are based on the deployment of the device. If the EBA-75 is carried daily it is to
be inspected daily. If the EBA-75 is stored according to an approved MSHA storage plan, it is to be
inspected every 90 days.
If the EBA-75 is stored in a protective storage container on a vehicle the inspections outlined below
are not necessary except for the 90-day inspection.
The EBA-75 is housed in a rugged transparent polycarbonate case. The case enables the user to
inspect the unit easily and in a minimum amount of time. The daily inspection as well as the 90-day
inspection should consist of the following:
(1)
Check the oxygen pressure gauge. The pressure gauge reading is normally 2250 psi at 70°F.
Remove from service if below 2000 psi or above 2500 psi at 70°F. If the case is damaged and the
gauge cannot be read, the unit must be removed from service.
(2)
Make sure that all the latch seals are not broken. Two seals are provided, one for each band. If
both seals are broken, remove the unit from service.
(3)
Inspect the apparatus for indications of abuse. If the view through the case is obstructed such that
a proper examination cannot be performed (e.g. scuff marks, stickers, and paint) the unit must be
removed from service. Indications of abuse are listed below. If any of these signs are present the
unit must be removed from service.
a. Case cracked, burned, or deformed
b. "U" seal bulged out, rolled or torn
c. Loose parts
·
Bottle strap (stainless steel)
·
Scrubber canister not in mounts
·
Screws or inserts
d. Bottle pad (red rubber) cut or displaced
e. Pressure gauge bent or indicator needle broken
f. Scrubber dented
g. Dirt, debris, or moisture inside case
h. Handle loops broken (the plastic loops that hold the handle straps)
i. One or both of the two handle straps (black nylon straps) missing or broken
(4)
Make sure that the yellow mouthpiece plug is in the mouthpiece. Remove the unit from service if
the plug is removed.
If the EBA-75 fails any of the above inspections, it should be removed from service and returned to
Ocenco, Incorporated. A summary of the inspection points is given on the next page.
