SAFETY PRECAUTIONS FOR USE
WITH PNEUMATIC TOOLS GENERAL
When using pneumatic tools, you should use the
You should wear and use necessary personnel
Pneumatic tools shall not be
connected to, or driven by, air pressure in excess of
that for which the tools are designed. The wearing of
appropriate eye protection equipment is mandatory for
Navy personnel when operating pneumatic tools.
You should be authorized and trained to
operate pneumatic tools.
Pneumatic tools should be laid down in such
a manner that no ham can be done if the switch is
accidently tripped. No idle tools should be left in a
Pneumatic tools should be kept in good
They should be thoroughly
inspected at regular intervals with particular attention
given to the ON-OFF control valve trigger guard (if
installed), hose connections, guide clips on hammers,
and the chucks of reamers and drills.
Pneumatic tools and air lines may be fitted
with quick-disconnect fittings.
incorporate an automatic excess-flow shutoff valve.
This valve automatically shuts off the air at the air
lines before changing grinding wheels, needles,
chisels, or other cutting or drilling bits.
The air hose must be suitable to withstand the
pressure required for the tool. A leaking or defective
hose should be removed from service. The hose
should not be laid over ladders, steps, scaffolds, or
walkways in such a manner as to create a tripping
hazard. Where the hose is run through doorways, the
hose should be protected against damage by the doors
edges. The air hose should generally be elevated over
walkways or working surfaces in a manner to permit
clear passage and to prevent damage to it.
All portable pneumatic grinders must be
equipped with a safety lock-off device. A safety
lock-off device is any operating control that requires
positive action by the operator before the tools can be
turned on. The lock-off device must automatically
and positively lock the throttle in the OFF position
when the throttle is released.
operations by the same hand are required, first to
disengage the lock-off device and then to turn on the
throttle. The lock-off device should be integral with
the tool. It should not adversely affect the safety or
operating characteristics of the tools, and it should not
be easily removable. Devices, such as a dead-man
control, that do not automatically and positively lock
the throttle in the OFF position when the throttle is
released are not safety lock-off devices.

NAVAIROSH Requirements for the Shore
In operating or maintaining air-driven tools, take
the following precautionary measures to protect
yourself and others from the damaging effects of
Inspect the air hose for cracks or other
defects; replace the hose if found defective.
Before opening the control valve, see that
nearby personnel are not in the path of the
Never point the hose at another
Open the control valve momentarily before
connecting an air hose to the compressed air outlet.
Then, make sure the hose is clear of water and other
foreign material by connecting it to the outlet and
again opening the valve momentarily.
Stop the flow of air to a pneumatic tool by
closing the control valve at the compressed air outlet
before connecting, disconnecting, adjusting, or
repairing a pneumatic tool.
As an ABE you will be required to read blueprints
and drawings during the performance of many
maintenance actions required to maintain the
operational readiness of the catapults and the arresting
gear engines. As you advance in rating you may also
be required to make sketches and drawings, which
will assist you in the training of less-experienced
