Policy

• A command supported electrical safety program
  shall be established. Activities are required to
  comply with Material Maintenance Management (3M)
  provisions, if applicable. Additionally,
  classroom spaces which are directly related to
  fleet training evolutions must comply with
  applicable provisions of OPNAVINST 5100.19
  (series) and NSTM chapter 300, as applicable.

10
(continued)

• All other spaces and non-training evolutions must
  comply with
• 29 CFR 1910 Subpart S and other related
  nationally recognized electrical standards, as
  adopted by
• OPNAVINST 5100.23 (series).

11
(continued)

• The maintenance and repair of electronic
  equipment ashore is governed by SPAWARINST 5100.9
  (series). Potential regulatory conflicts that may
  arise within the fleet-simulated training
  environments are to be resolved in favor of
  NAVSHIP/NAVSEA or
• OPNAVINST 5100.19 (series) as applicable.

12
A Electrical Safety program is...

• Designed to minimize electrical, fire and shock
  hazards

13
Poor Tension...

• Electrical receptacles that have poor tension
  increases resistance which eventually results in
  an electrical arc or fire.

14

• To protect personnel against short circuits, the
  grounding contact tension must be maintained so
  the grounding path is not breached.

15
Incorrect wiring, improper installation and worn
electrical equipment pose hazards to personnel
and equipment.
16
Poor tension on electrical conductors.
17
Ensure ALL electrical plugs have no exposed
wiring present during routine inspections...

Equipment will be checked for grounding, loose
wiring, frayed cords, intact grounding pin and
equipment damage. Electrical equipment used
around swimming pools shall be checked daily
prior to use.
36
Installations and changes to electrical wiring,
fittings, attachments, or other electrical
appliances shall be made by qualified personnel.
37
Defective electric cords, lighting fixtures,
appliances, receptacles and switches shall be
reported immediately to the BMS and the command
Safety Representative for corrective action.
38
All electrical apparatus must bear the label
of/or be listed by a testing/listing facility
(i.e., Underwriters Laboratories or Factory
Mutual).
