SAFETY SUMMARY
GENERAL SAFETY NOTICES
The following general safety notices supplement the specific warnings and cautions appearing elsewhere
in this manual. They are recommended precautions that must be understood and applied during operation and
maintenance of the equipment covered herein. Should situations arise that are not covered in the general or
specific safety precautions, the commanding officer or other authority will issue orders as deemed necessary to
cover the situation. No work shall be undertaken on energized equipment or circuits until approval of the
commanding officer is obtained, and then only in accordance with Naval Ships’ Technical Manual (NSTM)
S9086-KC-STM-010/Chapter 300.
DO NOT REPAIR OR ADJUST ALONE
Under no circumstances shall repair or adjustment of energized equipment be attempted alone. The
immediate presence of someone capable of rendering first aid is required. Before making adjustments, be sure
to protect against grounding. If possible, adjustments should be made with one hand, with the other hand free
and clear of equipment. Even when power has been removed from equipment circuits, dangerous potentials
may still exist due to retention of charges by capacitors. Circuits must be grounded and all capacitors
discharged prior to attempting repairs. Equipment should be deenergized and properly tagged out according to
the ship’s Standard Operating Procedures.
TEST EQUIPMENT
Make certain test equipment is in good condition. If a metal-cased test meter must be held, ground the
case of the meter before starting measurement. Do not touch live equipment or personnel working on live
equipment while holding a test meter. Do not ground any measuring devices; these devices should not be held
when taking measurements.
INTERLOCKS
Interlocks are provided for safety of personnel and equipment and should be used only for the purpose
intended. They should not be battle shorted or otherwise modified except by authorized maintenance personnel.
Do not depend solely upon interlocks for protection. Whenever possible, disconnect power at the power
distribution source.
MOVING EQUIPMENT
Personnel shall remain clear of moving equipment. If equipment requires adjustment while in motion, a
safety watch shall be posted. The safety watch shall be qualified to administer CPR, have a full view of the
operations being performed, and have immediate access to controls capable of stopping equipment motion.
FIRST AID
An injury, no matter how slight, shall never go unattended. Always obtain first aid or medical attention
immediately, and file an injury report in accordance with OPNAVINST 5102.1 series, subj: Mishap
Investigation and Reporting.
