OPERATION.
WARNING
The following warnings, although numerous, should be strictly adhered to for safe operation of the equipment.
When compressor unit(s) are operating, the operator(s) and other
personnel in the area should wear sound attenuators. The area must be
posted as a noise hazard.
Shut down the compressor if 3260 psi pressure in the final stage is
exceeded. Refer to the Compressor Maintenance Schedule Table 4-1.
Do not operate the compressor until the problem has been identified and
corrected.
Do not fill any cylinder if the cylinder inspection date has expired, i.e., five
years.
Charge cylinders at a slow rate to prevent excessive heat buildup. Never
perform maintenance or repair on a cylinder valve when the cylinder is
charged.
Handle cylinders carefully. Avoid having the cylinders slip or drop. Do not
lift or carry cylinders by the manifold.
Store cylinders in an upright position in a cool, shady place to prevent
overheating.
Secure cylinders properly. This includes blocking and strapping them.
The enormous potential energy of a fully charged SCUBA cylinder
necessitates that special stowage maintenance and handling precautions
be observed.
Internal inspections, hydrostatic tests, and repair work on cylinders should
be accomplished only by those trained to do so.
Have cylinders inspected for interior deterioration annually. Inspect
cylinders externally before and after each use for signs of deterioration,
corrosion, dents, cracks, or other damage. Never use a dented, welded or
scarred cylinder.
Never fill a cylinder designated for another gas or which was previously
filled with another gas. Never fill an oxygen tank. Danger of explosion
exists.
The filter adapter and recharge connection should be thoroughly inspected
prior to servicing and any trace of oil, grease, or foreign material carefully
removed. Use only those adapters and connections supplied and
designed for this equipment.
Secure the dust cap between the
handlescrew and the adapter seat when the filling adapter is not in use.
Never open filling valve when under pressure and not connected, as highly
compressed air emerging can cause serious accidents.
Check air tightness of compressor from time to time by brushing all fittings
and couplings with soapy water to detect air bubbles, indicating an air
leak. Repair all air leaks.
Filling hose must always be in satisfactory condition and threads
undamaged. Discard worn or damaged hose.
Permit only qualified personnel to use this equipment.
Complete
familiarity is a basic prerequisite to safe operation techniques. The
operator must always be in attendance when equipment is in use.
