Rescue common sense electric shock injury

The electric shock accident that we usually live is caused by the energy of electric current, and it is the injury of electric current to the human body. Current damage to the human body can be divided into two types: electric injury and electric shock. Electric injury is a local injury to the human body caused by the thermal, chemical, or mechanical effects of current. The so-called electric shock accident basically refers to the shock. Electric shock is the damage caused by current passing through the body and destroying the normal functions of the heart, nervous system, and lungs. The electric shock may be caused by the human body touching live wires, the casing of the leakage device or other charged objects, and lightning or capacitor discharge. A shock that touches a normal live body is called a direct shock, and a shock that touches a faulty live body is called an indirect contact shock.

1. The on-site rescue of electric shock can be divided into the following points:

1 Cut the wire : If the switch distance is long, the ambulance personnel can use various methods to cut off the wire immediately. Such as using electrical pliers to cut off the wire, or with a wooden handle knife, ax, pick, shovel, etc. cut off the power cord, you can also take advantage of the fire line, the zero line causes a short circuit, so that the main power supply tripping and other methods to cut off the power.

2 Turn off the power switch : Once someone gets an electric shock, especially when working in wet or water, the ambulance personnel should immediately close the switch, pull the switch, pull out the plug or take out the insurance, and immediately remove the electric shocker from the power supply as soon as possible.

3 If you open the electric shocker : If the above method can not rescue the electric shocker, and the electric shocker is on the charged object again, dry ropes, cloths, etc. can be used to cover the electric shocker and pull it out. You can also pull it out with insulating gloves. Ambulance personnel should pay special attention to their own protection at this time.

Stand on insulating objects such as planks or quilts. It is forbidden to pull the electric wire or the electric shocker directly by hand to prevent the electric shock caused by the chain.

4 Pick the power cord: If you cannot use the above method, you should quickly find dry sticks, bamboo sticks, etc., and pick the power cord of the person who is getting an electric shock. Do not use metal materials or wet objects to pick the power cord. Be careful not to make the wires. Bounce to yourself.

5 Rescue points :

a. When the symptoms of electric shock injury are light or the emergency is improved, they should be allowed to rest quietly. During the journey to the hospital, attention must be paid to the observation to prevent the sudden increase in severity.

b. Give localized burn wounds a blanket dressing.

c. For the rescue of the electric shockers, we must try our best to create conditions for the rescue on the spot. Do not move the electric shockers to maximize the rescue time.

d. If there is a heartbeat from a person who is getting an electric shock, the ambulance personnel should first perform a slamming at the precordial area several times, and if it is not valid, perform a chest cardiac press.

e. If the person who is getting an electric shock stops breathing, perform mouth-to-mouth artificial respiration immediately.

f. If the person who received the electric shock is seriously injured, the heartbeat and breathing are stopped, and artificial respiration and cardiac squeezing should be performed at the same time.

g. Precaution

2. The causes of electric shock are many and can be roughly classified into the following categories :

1 As the insulation performance of the live equipment is reduced or the insulation layer is damaged, the human body will get an electric shock once it comes into contact with it;

2 Live working, not taking necessary protective measures to cause electric shock;

3 Power outage and maintenance, starting inspection without inspection of electricity or warning signs without hanging on the power line;

4 The safety distance between the human body and the conductive equipment is insufficient to cause electric shock.

3. The main symptoms of electric shock

Electric shock is an injury caused when a human body touches an electric current or close to a high-voltage electric shock when operating or using electric equipment. It is broadly divided into electromagnetic injury accidents, current injury accidents, electrostatic accidents, lightning strike accidents, and electrical equipment accidents. Electric shock injuries are common in production.

Seriously life-threatening. The main symptoms of human body after electric shock are as follows:

1 local symptoms

When the body is partially exposed to electrical current, local electrical burns may occur due to high heat and electrical sparks. There are generally more than two wounds, one for the import and one for the export. The wounds are generally small, but deeper and brownish and irritated. If you touch high voltage (1000 volts to

Top) is the most obvious.

2 systemic symptoms

a. If the current is low, the voltage is low, and the contact time is short, the person with electric shock may experience dizziness, palpitations, nausea and other symptoms.

b. If the current is strong, the voltage is high (above 65 volts AC, more than 300 volts DC), and the contact time is long, it may cause electrical shock (also known as suspended animation), that is, the person who receives the electric shock loses consciousness, pale, pupil dilation, pulse stop and breathing. stop. If not

Taking the right measures to rescue them will result in death. This is the main symptom of electric shock.

c. It is worth noting that the above symptoms may be mild at the time of the electric shock, but suddenly become worse after an hour and there are symptoms of coma, breathing, and heartbeat.
