1-11. SAFETY, CARE, AND HANDLING.
a.
This manual is not intended to dictate safe diving operations or procedures. Diving supervisors are ultimately
responsible for conducting safe diving operations in accordance with approved regulations and instructions
b.
Always shut down and depressurize the system, using the purge valve, to carry out any work on the compressor.
Failure or observe this warning may result In injury or death to personnel.
c.
Never resolder or reweld pressure lines.
d.
Check for leakage of the complete system from time by brushing all fittings and couplings with non-ionic detergent
water solution. Remedy any leakage.
e.
Connecting hoses must be In satisfactory condition and threads undamaged. Pay particular attention to damage
on the interface from hose fitting to hose. If the rubber is scored, or wire-braided hose is frayed, the hose must be
discarded.
f.
Leave 11/2 threads or the first few threads of a fitting exposed when applying Teflon tape. This will ensure no
Teflon tape will hang down into the air or fuel system. Teflon tape should be wrapped in such a manner that when the
fitting is tightened, the tape will not loosen Incorrectly wrapped tape may result in contamination or blockage of the air or
fuel system and subsequent possible injury to the diver.
g.
Ensure that all air lines and components removed are inserted into a plastic bag and sealed, and that FMEC
(Foreign Material Enclosure Caps) are inserted into openings. Failure to do so can cause the air system to become
contaminated and could result in injury or death to the diver.
h.
Do not use trichloroethylene or methyl chloroform in cleaning operations associated with any diving system Use of
either chemical or similar contaminants can result in death when operators/divers are exposed to these contaminants
under pressure. These contaminants are not water soluble. If contamination or suspected contamination occurs,
immediately discontinue all diving equipment operations and notify Commander, U S Army Engineering Center, DSN 676-
7309 / and 7325 Commercial (314) 563-7309. The only acceptable cleaning agents are tribasic sodium phosphate and
non-ionic detergents (NID).
i.
Remove all traces of lacquer thinner with non-ionic detergent solution and rinse with fresh water Residual lacquer
thinner will contaminate atmosphere and may cause injury or death to personnel
j.
Repair or replace worn or damaged parts immediately with authorized parts. Failure of a component during
equipment usage could result in injury or death to personnel.
k.
Clean mechanical parts and softgood components in accordance with NEDU instruction 7121.A.
CAUTION
TO AVOID DAMAGE, REMOVE THE HOURMETERS BEFORE CLEANING THE
ENGINE OR COMPRESSOR UNIT WITH HIGH PRESSURE WATER/STEAM.
l.
The engine and compressor can be cleaned with a pressurized cleaning system (steam cleaner), but care must
be taken. Cap off engine and compressor intakes. Do not spray water (steam) directly into the instruments or back of the
instrument panel. If possible, dry with low pressure compressed air and run the unit immediately after washing to prevent
rust and corrosion.
