few seconds in each direction to be sure that the
wrench and its reversible features are functioning
correctly. When you are sure the wrench operates
properly, place the suitable equipment on the impact
driving anvil and go ahead with the job at hand.
SAFETY PRECAUTIONS FOR USE WITH
PORTABLE ELECTRICAL TOOLS
When portable electric tools are used, you should
use the following procedures:
Before portable electrical tools are used they
must be inspected and approved for shipboard use by
the ships electrical safety officer.
Prior to the use of any portable electric tools,
you should make sure the tools have a current ships
inspection mark. Additionally, visually examine the
attached cable with the plug and any extension cords
for cracks, breaks, or exposed conductors and
damaged plugs. When any defects are noted, the tools
should be turned in to the ships electrical shop for
repair before use.
Before plugging in any tool, be
sure the tool is turned off.
Personnel using portable electric tools are
required to wear safety glasses/goggles.
Portable electric tools producing hazardous
noise levels in excess of the limits set forth in
OPNAVINST 5100.19 (Series) are required to be
Personnel using tools
designated as producing hazardous noise levels are
required to wear proper ear protection, as issued by
the medical department.
Only explosion-proof (class I, group D, or
better) portable electric tools should be used where
flammable vapors, gases, liquids, or exposed
explosives are present.
Hand-held portable electric tools authorized
for use on board ship shall be equipped with ON/OFF
switches, which must be manually held in the closed
ON position to maintain operation.
Rubber gloves must be worn when you are
using portable electric tools under hazardous
conditions; for example, wet decks, bilge areas,
working over the side, in boats, and so forth.
Leather glove shells should be worn over
rubber gloves when the work being done, such as
sheet metal work, could damage the rubber gloves.
SAFETY PRECAUTIONS FOR
USE WITH EXTENSION CORDS
You should use the following procedures when
using extension cords:
Only three-wire extension cords that have
three-pronged plugs and three-slot receptacles should
Because a metal hull ship is a hazardous
location, personnel who must use portable electric
devices connected to extension cords should take the
time to plug the device into the extension cord before
the extension cord is inserted into a live bulkhead
Likewise, the extension cord should be
unplugged from the bulkhead receptacle before the
device is unplugged from the extension cord.
Electrical cords shall be cared for as follows:
Cords should not be allowed to come in
contact with sharp objects.
The y should not be
allowed to kink nor should they be left where they
might be damaged by vehicle/foot traffic. When it is
necessary to run electrical leads through doors and
hatches, the cords must be protected to guard against
accidental closing of the doors/hatches.
Cords must not come in contact with oil,
grease, hot surfaces, or chemicals.
Damaged cords must be replaced. They are
not to be patched with tape.
Cords must be stored in a clean, dry place
where the they can be loosely coiled.
Cords extending through walkways should
be elevated so they do not become a tripping hazard
or interfere with safe passage.
Extension cords should be no longer than
25 feet (except repair locker and CV flight deck cords,
which are 100 feet long). No more than two such
cords should be connected together for the operation
of portable equipment.
