Top 40 Plus Safety Rules for Working with Electrical Equipment

Written by Thalib Tantary

A safe work environment is not always enough to control all potential electrical hazards. You must be very cautious and work safely. Safety rules help you control your and others risk of injury or death from workplace hazards.

If you are working on electrical circuits or with electrical tools and equipment, you need to use following golden safety rules:

Rule No. 1

Because of special nature of electrical work, employees working on electrical equipment must be cautious and alerts all times, recognizing the seriousness of consequences which might result from a mishap. There are many unanticipated and unusual happenings that can lead to trouble in electrical work. Regard all electrical equipment as potentially dangerous.

Rule No. 2

Use electrical gloves while working on live lines.

Rule No. 3

All voltages should be handled properly and safely. It must be realized that relatively low voltages such as 240 V can cause injury. Very special care should be exercised when working.

Rule No. 4

A moment of neglect can result in life time of regret. Avoid working on live equipment in so far as practicable. Trouble shooting and making connections to energized 440 volts circuits or higher must be done under the supervision of an authorized  Electrical Supervisor.

Rule No. 5

When attending electrical defects, one must have permit to work on line and line should be isolated.

Rule No. 6

When it is necessary to work on or near live circuits, it is important to work on only one wire at a time and to insulate all conductors which may come in contact with the body.

Rule No. 7

Adequate protective equipment must be used when working on live circuit. Special attention should e given to rubber gloves to be sure these are good condition.

Rule No. 8

Fuses of proper amperage should be used according to the load on the lines.

Rule No. 9

Only non conductive ladders should be used by electrical works.

Rule No. 10

Insulation of electrical wire cannot always be depend upon to give protection from shock. Familiarization with the conditions at hand essential.

Rule No. 11

Treat all electrical equipment designed for 440 volts and above as though it were live, even though it is known or believed to be dead or de-energized.

Rule No. 12

Keep the area around electrical equipment dry to minimize possibility of shock. Obtain dry boards to stand on if necessary.

Rule No. 13

In so far as practicable, work shall not be performed on electrical equipment having moving parts while it is operation.

Rule No. 14

When it is necessary to work on electrical circuit or other electrical equipment or to dismantle or remove machinery driven by electrical motors, the proper switches must be opened and tagged.

Rule No. 15

As an additional precaution, fuses must also be pulled out where provided.

Rule No. 16

Never bridge a fuse or use a fuse which is heavier than the capacity of the circuits. Replaced fuses should be of the same capacity as those removed.

Rule No. 17

Every machine or electrical equipment must be properly earthed.

Rule No. 18

Never leave broken plugs, sockets, switches and worn out cable as such and thees should with electrical equipment.

Rule No. 19

Finger rings, bracelets and metal wrist should not be worn by persons working with electrical equipment.

Rule No. 20

Tags are to be used on switches when these are opened to permit work on electrical equipments.

Rule No. 21

Electrical switches must be tagged properly by authorized persons when electrical motor driven equipment is to be worked on.

Rule No. 22

Never close a switch without first having full knowledge concerning the circuit and the reason why the switch was tagged open previously.

Rule No. 23

Do not operate any oil immersed switch with the oil pan in the lowered position.

Rule No. 24

On 2,400 volts and above, make sure the disconnect switch on the line is open and tagged out before opening the enclosure or dropping the oil tank of a circuit breaker, starter, or other electrical device.

Rule No. 25

In opening disconnects, shield the eyes from a possible flash. In opening disconnects of any kind, wear rubber gloves. Use a disconnecting pole on high voltage.

Rule No. 26

Be sure the circuit breaker is open before attempting to remove draw out type circuit breaker from their voltage.

Rule No. 27

Replace cover plates on lights and power cabinets or other electrical enclosures after repairs.

Rule No. 28

Safety belts shall be a part of a line men’s equipment and shall be used whenever the lineman is supported with climbing hooks at an elevation. Lineman should check their safety belts before each use.

Rule No. 29

Ground and short circuit any line as close to the work as possible. Grounds should be clamped to pole ground wires or an overhead ground wires.

Rule No. 30

Handle telephone or signal wires with care since these any come in contact with high voltage wires, thus, becoming dangerously charged.

Rule No. 31

In working hot lines 440 volts over, two men should always work on the pole together except when changing fuses. One man must keep himself in the clear and in a position to aid his pole mate if necessary.

Rule No. 32

Personnel working elevated hot circuits from the insulated brackets ate the aerial platform truck should make certain that lose materials being handled to not ground them to the machinery.

Rule No. 33

Temporary installation shall confirm to generally excepted safety practices. It is particularly important that all electrical installation be properly grounded, sufficient clearances be provided over rail roads and roadways and proper type equipment be installed in gaseous areas.

Rule No. 34

Suitable barricades must be installed around exposed temporary high voltage electrical equipment such as filed transformer.

Rule No. 35

Never use metallic ladders in electrical work or near electrical equipment.

Rule no. 36

Inspect all electrical extensions before placing in service. Avoid wrapping cord around any part of the body.

Rule No. 37

Ground all electrical power tools. Examine electrical extension light or portable tool cables for defect before using.

Rule No. 38

Use only 24 volts for hand lamps.

Rule No. 39

Do not make loose connection. Do not insert naked wires in to the sockets. Use a proper plug for each equipment with earth connection. Never leave the earth wire unconnected.

Rule No. 40

Do not make temporary connection with loose wires hanging around.

Rule No. 41

While working with portable tools, check for worn ot wires, loose connections, or broken plug.

Since most often students find it difficult to understand their text books or even there many who can not afford such books, therefore we prepared ourselves to solve this problem faced by them.
