Maintenance and repair of electronic equipment ashore



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.



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).



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.

a electrical safety program is

A Electrical Safety program is…...

Designed to minimize electrical, fire and shock hazards

poor tension

Poor Tension…...

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

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

Incorrect wiring, improper installation and worn electrical equipment pose hazards to personnel and equipment.

electrical receptacle requirements

Electrical Receptacle Requirements

A vigorous receptacle testing program shall be conducted. Each receptacle shall be tested at least annually. Defective receptacles shall be replaced.

The Following slides describe what shall be verified:

The physical integrity (NOT CRACKED OR BROKEN) for each receptacle shall be confirmed by visual inspection.
Correct polarity of the hot, neutral and grounding connections in each electrical receptacle shall be confirmed.




The retention force of each connection (hot, neutral and grounding) of each receptacle (except locking type receptacles) shall not be LESS than four ounces.


A record shall be maintained for electrical inspections. Each receptacle need NOT be listed. Areas specific to the inspection should be noted (e.g., Building 1405, 2ud deck). List discrepancies and abatement action.

gfci receptacles shall be tested both receptacles of a duplex gfci receptacle shall be tested
GFCI receptacles shall be tested. Both receptacles of a duplex GFCI receptacle shall be tested.

A program of regular (at least annually) inspection of electrical equipment including receptacles to detect and correct unsafe conditions in all buildings, barracks, etc.


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.

Installations and changes to electrical wiring, fittings, attachments, or other electrical appliances shall be made by qualified personnel.

Defective electric cords, lighting fixtures, appliances, receptacles and switches shall be reported immediately to the BMS and the command Safety Representative for corrective action.


All electrical apparatus must bear the label of/or be listed by a testing/listing facility (i.e., Underwriters Laboratories or Factory Mutual).


Locally prepared extension cords made with handy/junction boxes with knockouts are prohibited. Multi-receptacle adapters (octopus) are prohibited.


An electrical tool issue, testing and repair program shall be instituted. Procedures governing tool control, safety and use should be promulgated at the command level.

gfci protection that is 125 volt single phase 15 20 amperage shall be present for the following
GFCI protection that is 125 volt, single phase, 15-20 amperage shall be present for the following...

Outdoors where there is direct grade level access (located not more than 6 feet 6 inches above the ground) to the receptacles.

In bathrooms, kitchens and deep sink rooms where receptacles are within six feet of sinks.

In garages


A record will be maintained and a durable tag affixed to floor buffers certifying serviceability and date of last inspection. For all other equipment, either a tag or a system of colored tape attached to the cord may be used.

Test and inspection of electrical insulated gloves will be in accordance with 29 CFR 1910.137 with records of tests being maintained.
Audio Visual personnel are responsible for maintenance and repair of government owned training aid equipment.
