Safety Methods Of Electrical Work


Safety procedures

Safety is the process of doing electrical work by practicing safety conditions properly, that is, the method by which electrical work can be solved efficiently by keeping oneself safe is called the safe work method.

Possible causes of accidents

1. Violation of electrical laws.

2. If you do not use controlling equipment.

3. If you use defective goods and equipment.

4. If you are inattentive to work.

5. If there is a lack of common sense.

6. If there is eternal faith in the subject matter.

Safety terms and precautions

1. It is very easy to get an electric shock. Again, it can be easily resisted. Therefore,

caution should be exercised.

2. If you see someone sticking to a running line and have no main sewer on hand, place yourself on a piece of dry wood or thick paper, grab the affected person’s clothes, if the clothes are dry or a piece of wood, bamboo or Will hit by national objects and will arrange artificial respiration if necessary.

3. A septic belt must be used when a person is working on a pole or a tower.

4. Where there is electricity running, he will not catch it unnecessarily. Find out if the electrical machine or equipment or running appliance has been earthed properly.

5. Do not run electricity until you are sure that a person is working on an electric machine or on an electrical line.

6. It is a bad habit to open the plug holding the plug. This must be avoided.

7. The main switch must be turned off when replacing the fuse.

8. Never connect the connecting device without safety measures.

9. Plenty of light and air should be provided in the battery charging room.

10. Will always connect the phase wire switch.

11. When sulfuric acid or caustic soda is mixed with water, it is always dangerous to pour acid or

soda gently into the water.

12. If at any time the electric wire catches fire, do not put water in it. It will be dangerous for you.

13. When using a fire hose, make sure that the water does not touch any phase wires.

14. If the electrical wire catches fire, the supply will be cut off immediately.

15. Before using electrical wires, make sure that the wires have insulation.

16. It is strictly forbidden to work on overhead lines when lightning strikes in the sky. Because, if it is not earthed, then electricity can flow

in that line and cause death.

17. When riding on a traveling crane and working on an overhead line, the crane driver must be told not to operate the crane voluntarily.

18. When working with a ladder, the ladder must be placed properly and, if necessary, one must hold the ladder for safety.

19. Never touch the overhead line wire until you are sure that the line supply is off or well-grounded.

20. The handle of the Molten solder must be held tightly. Don’t fall, because if you fall, there is a fear of getting burnt.

21. Always wear rubber gloves, rubber boots, rubber apron, septic helmet, septic belt, septic goggles, etc. while doing electrical work.

22. Do not move any electrical machine or controlling device without permission.

23. Never pull the flexible wire apart. Because it is very dangerous.

Electrical work equipment to avoid accidents

(1) Fire Extinguisher.

(2) Carbon dioxide extinguisher.

(3) Carbon Tetrachloride Extinguisher.

(4) One bucket of water, one bucket of water.

(5) Dry wood or thick paper.

(6) National hand gloves for insulation.

Safety First aid

Accidents can happen inside or outside the factory. First aid is the first treatment of such an accident victim.

The need for first aid

In the absence of a little treatment, the patient’s condition may become critical or even death. This is why first aid is needed. Therefore, it should not be neglected at all.

Ways of first aid

1. The injured person should never be intimidated.

2. The person with the accident should be carried to a convenient place and should be rushed to a doctor.

3. Check if the injured person’s breathing is working properly and check as much as possible if there is an injury, cut, or broken.

4. If the injured person stops breathing, then artificial respiration should be done immediately. And sterile dressing-bandaging should be given.

5. Appropriate measures should be taken to stop the bleeding as soon as possible as the condition of the person injured due to bleeding may be alarming.

6. If consumed by electrical flashes or flames of hot liquids, apply sterile dressing-bandage and if burnt by acid or alcohol, rinse thoroughly with water.

7. If it breaks somewhere, the injured person must be carried carefully and never use force on the broken part – until the

injured person moves.

8. Never let an unconscious person drink water or liquids. But if you are aware, you can drink water.

9. Never surround the person involved in the accident, because the injured person needs free air. The injured person should never be informed of how much has been injured or damaged.

10. Nothing more or less should be done.

11. Arrangements should be made to send the injured person to the hospital as far as possible.

Safety Electric shock

(1) If a sufficient amount of current flows in the body of the injured person.

(2) If current flows in the body for a long time.

(3) The vibration of the current when struck by the waves of the heart of the body.

(4) If the physical and psychological condition of the injured person is very deplorable.

The name of the equipment for first aid

Such as- scissors, cotton, bandage, dissecting forceps, sulfanilamide powder, tincture iodine, tincture benzene, leucoplast roll, Dettol or Savlon lotion, needle, needle holder, yarn, etc.

The amount of current flowing in the human body

The amount of current flowing through the body depends on the body’s earth resistance (especially on the condition of the skin inside and outside the body) and the voltage at which a person’s body is dry,

If that is the case, the resistance in his body is 10 to 600 kilo-ohms h. And if it is wet, it is 1 kilo-ohm. The wet body easily connects with the soil. Because there are only a few hundred resistances. When a current of 2 mA to 10 mA of current flows through the human body, the flesh of

the human body contracts and the muscles are injured.

It is very painful when the current flows from 5 mL to 25 mL (mA) and the injured person cannot be completely disconnected from the electric wire. If a current of 25 mA current flows through a person’s body for more than three seconds, then there is a possibility of death.

And if more than 25 milliamperes of current flows, then the muscles will contract severely. If the current flows from 50 to 200 milliamperes, it will close the heart. If the current flows more than 100 milliamperes, breathing may stop.

And if that person is connected to a 120-volt conductive wire, that person can still die. (If the resistance in his body is 1 kilo-ohm) then 50 volts is more deadly than 250 volts at that time.

The way electricity flows

The amount of electricity flowing through the body and the amount of damage will depend on the way the electricity flows. If the electricity goes from the body to the ground with the help of the feet, then there may not be much fatal damage.

But if a small amount of current flows through the human heart, it will be severely injured. It can even lead to death.

People can get electric shock due to various reasons

1. If a person is standing on the ground, touching any part of the body that is hot can cause injury.

2. If anyone stands on the ground due to electrical insulation or touches the body with the ground, he will be injured.

But if it is connected to two or more conductors, and if there is a potential difference between those conductors, then it must be

sufficiently injured. Safety

3. If a person comes in contact with the frame of an electrical device or appliance, that person will also be injured for a poor insulation or poor earthing.

4. If the rescuer did not protect himself before going to rescue the person who received the electric shock, then that person will also be injured.

Electric Shock Treatment

For a person whose heart is weakened and his breathing stops due to an electric shock, this method of artificially rescuing a dying person is as follows:

(1) The method of treatment by uprooting. (2) The method of treating the head. (3) The method of treating the head. Safety

Reverse treatment method

Reverse treatment method

There are different types of artificial treatment. The Holger Nelson method is used in it. The injured person should lie down on the ground in a convenient place and keep his left hand on the stoma and his right hand under the head. This time the doctor will treat the injured person, he will place the left leg on the ground with the left leg facing the injured person and the right leg near the injured person’s elbow on the ground according to

Figure 1.

The doctor will touch him with the fingers of both hands and hold his hand upright and apply pressure for two seconds. Just when that pressure is applied, air will come out of the lungs,

This is shown in

Figure 1.

Then the doctor’s hand should be gently placed on the elbow of the electrically injured person according to Figure 2 and the electrically injured person should be placed on the shoulder and gently held above the elbow according to

Figure 3.

The physician should place the left leg on the ground like a needle and try to pull the injured person out. In this case, lightning will blow air out of the injured person’s lungs quickly. The above process should be completed within two seconds. Then the power should return to its previous state in three seconds without putting any pressure on the injured person’s body. That is to return to the state according to Figure 1. This process should be done 10/12 times per minute. Safety

Straightforward treatment

Straightforward treatment

(1) If the mouth of the injured person is closed, then the mouth should be opened by hand.

(2) If the head of the injured person is tilted, then the head should be kept straight.

(4) Then the air should be drawn in and out of the lungs of the injured person. That is to say, you have to run the way you breathe.

(5) This process should be done 10/12 times per minute.

Provision for treating a person who is in shock while at the head of a pole

electric pole

A person is shocked when he is on top of an electric tower or electric pole. If he can be artificially inhaled over a pole or tower, In that case, he should not be demoted. Because, if he goes down, his condition may get worse. This method of artificial respiration is called pole therapy. When the injured person can breathe on his own, there is no difficulty

in lowering the injured person from the top of the pole.

The way the head of the pole is treated is shown in the figure. If a person is shocked at the head of a pole, then the condition of the injured person should be immediately known.

If possible, the supply line should be switched off, if it feels safe.


Fire is extremely necessary for practical life and again extremely dangerous. Various fires can occur. For example, cigarettes, bidis, electrical sparks, and flammable substances can cause fires due to misplacement. Without it, due to lack of maintenance, fires can occur due to excessive load and electrical fire. However, in case of fire, it is necessary to always be careful. If possible, notify the fire brigade by telephone and use a fire extinguisher if you have one. The following are the types of fire extinguishers:

Extinguisher mixed with soda-acid

This type of extinguisher is hollow. It contains soda mixed water and a small glass flask containing sulfuric acid. Carbon dioxide is produced when water mixed with soda reacts with acid. This gas is supplied by the hose pipe. This type of extinguisher

can be used from a distance of 10 meters. It is commonly used to light fires on wood,

paper, and cloth. But it is not used for petrol, oil and electrical fire.

Carbon dioxide extinguisher

This type of extinguisher has a deer type tube. As a result, liquid carbon dioxide is easily released. It contains liquid carbon dioxide. When carbon dioxide comes out of the flux, it comes out in the form of vapor and it extinguishes the fire. It is commonly used in electrical fires.

It is also used where liquids catch fire. One of its disadvantages is

that it cannot be used in the open. But can be used in closed places.

Foam extinguisher

This type of extinguisher is used in combustible liquids. Apart from that, it can also be used in case of fire. But cannot be used in electrical fires? Such extinguishers contain water and sodium carbonate. Aluminum sulfate powder is used in it to make it stronger. It reacts to form foam and releases carbon dioxide in the form of bubbles.

Carbon Tetrachloride Extinguisher

It has a cylindrical flux. It contains carbon tetrachloride in a liquid state. When carbon tetrachloride comes out of the flux, it comes out in the form of vapor. It is heavier than air. So it is very effective in extinguishing a fire in an electrical fire. But it cannot be used indoors. Because its vapor is highly toxic.
