Be careful what the signs of electric shock are Beware of the electric shock signs

The <>Beware of Electric Shock" sign is a safety sign.

one. Safety signs are used to express specific safety information signs, which are composed of graphic symbols and safety colors.

Geometric shapes (borders) or text compositions.

Safety signs are signs that warn workers of dangerous conditions in the workplace or surrounding environment and instruct people to behave appropriately. Safety signs can alert staff to prevent hazards and thus avoid accidents; When danger occurs, people can be instructed to flee as soon as possible, or people can be instructed to take correct, effective and effective measures to contain the hazard.

The type of safety sign should not only be consistent with the content of the warning, but also the correct and reasonable position, otherwise it will be difficult to give full play to its warning role.

Setting of safety signs:

1) Safety signs should be set up in conspicuous places related to safety and ensure that people have enough time to pay attention to what they indicate.

2) When safety signs are placed on walls or other existing structures, the background color should contrast with the main color on the signs.

3) Safety signs set up in a specific location should be firmly installed to ensure that they do not pose a danger themselves, and all signs should have a solid structure.

4) Safety signs that display information that is no longer useful should be removed immediately from the installation, which is especially important for signs that warn of special temporary hazards that would otherwise lead to observers.

Ignoring and interfering with other useful signs.

5) When multiple signs are set up together, they should be arranged in the order of warning, prohibition, instruction, and prompt type, first left and then right, first up and then down.

It generally consists of black characters on a yellow background and black **. The black lightning bolt sign in the sign will have a large black triangle around it, and there will be a warning sign beneath it that says watch out for electric shock. When an electric current is passed through the body, it causes damage to tissues and organs.

Pay attention to the use of electricity.

This kind of sign is usually placed or hung in transformers, distribution rooms, high-voltage line towers, distribution cabinets and other places, reminding people to prevent electric shock, due to the lack of knowledge of safe electricity, the installation and maintenance of electrical appliances and wires are not carried out in accordance with the regulations, is one of the causes of electrical injury, in daily life, hang clothes on the wires, with high temperature, high humidity ** surface contact wires, sweating, may cause electric shock.

Risk of electric shock.

Electric shock accidents can occur when the human body touches a live body, the enclosure of a device that is live due to insulation damage, or when it is close to a high-voltage live body. Due to the special working conditions in the underground, coupled with poor management, untimely maintenance, and even illegal operations, the possibility of electric shock is greater.

The injury of electric shock to the human body can be roughly divided into two situations: electric shock and electric injury. Electric shock refers to the electric current passing through the human body after electric shock, which causes damage and destruction to the respiratory organs, heart and nervous system under the action of thermochemical and electrical energy, and in most cases electric shock can cause death.

The sign of being careful of electric shock is generally composed of black letters and black pictures on a yellow background, and there will be a large black triangle around the signBlack lightningsign, below which there will be a slogan text reminder to be careful of electric shock. When the current passes through the human body, it will cause damage to tissues and organs, and attention should be paid to the use of electricity

Such signs are usually placed or hung in transformers, distribution rooms, and high-voltage lines.

Towers, distribution cabinets and other places remind people to prevent electric shock. Due to the lack of knowledge of safe electricity use, the installation and maintenance of electrical appliances and wires are not operated according to the regulations, which is one of the causes of electrical injuries.

Hanging clothes on wires in daily life, high temperature, high humidity and sweating ** surfaces touching wires may cause electric shock.

Manifestations of electric shock.

When the human body is exposed to electric current, the mild person immediately appears panic, sluggishness, paleness, muscle contraction at the contact site, dizziness, and tachycardia.

and malaise. In severe cases, coma, persistent convulsions, ventricular fibrillation, and arrest of heartbeat and breathing may occur.

Some people with severe shocks have symptoms that are not severe at the time but suddenly worsen after 1 hour. Some patients have extremely weak heartbeats and breathing after being electrocuted, or even temporarily stopped, in a state of "suspended animation".

As shown below:

Such signs are usually placed or hung in transformers, distribution rooms, and high-voltage lines.

Towers, distribution cabinets and other places remind people to prevent electric shock, due to the lack of knowledge of safe electricity use, the installation and maintenance of electrical appliances, wires do not operate according to the regulations, which is one of the causes of electrical injury.

In daily life, hanging clothes on wires, high temperatures, high humidity and sweating surfaces touching wires may cause electric shock.

Electrocution method:

First of all, single-phase electric shock usually refers to the fact that when a person comes into contact with a certain phase conductor in a live device or line, the current flows through the human body through the earth to the neutral point.

Secondly, biphasic electric shock means that a person comes into contact with two phase wires at the same time.

or phase voltage.

and phase voltage, the risk of electric shock is greater than that of single-phase electric shock.

Thirdly, the contact voltage is electrocuted, and electricians, especially maintenance electricians, will be electrocuted when the human body comes into contact with the live equipment shell due to factors such as the electrical grounding protection device is not standardized, or due to factors such as zero fire connection error.

Finally, it is the step voltage electrocution, which is the electrocution that occurs within 8 10 meters of the high-voltage power line landing point. If you accidentally enter the landing range of the high-voltage line, you should put your feet together and jump away from the scene like a zombie.

Beware of the electric shock sign:

Electric shock often refers to the direct contact of the human body with a power supply or high voltage.

Tissue damage and dysfunction caused by the transmission of electric current through air or other conductive media through the human body, and in severe cases, cardiac and respiratory arrest occur. High voltages above 1000 V (volts) can also cause burns. Lightning damage (lightning strike) falls under the category of high-voltage electrical damage.

There are many causes of electrical injuries, mainly due to lack of knowledge of safe electricity use, installation and maintenance of electrical appliances, wires not operating according to regulations, and hanging clothes on wires. High temperature, high humidity and sweating make the ** surface.

The solution is to turn off the power; Pick up the wires.

1) Turn off the power If the electric shock occurs at home or near the switch, it is the simplest, safest and most effective way to quickly turn off the power switch and pull the main switch knife of the power supply.

2) Pick up the wire, use a dry wooden stick, bamboo pole, etc. to pick the wire from the person who is electrocuted, and fix the wire to avoid electrocution by others.

3) If the cutting circuit is in the field or away from the power switch, especially in rainy days, it is inconvenient to approach the electrocuted person to pick up the power cord, you can use insulated pliers 20 meters away from the site.

or a shovel with a dry wooden handle.

Axes, knives, etc. cut off the wires.

4) "Pull away" the electrocuted personIf the electrocuted person is unfortunately lying on the iron-clad machine, the rescuer can put a dry wooden board or plastic board under his feet, and use dry and insulating cloth strips, ropes or clothes to wrap them around the electrocuted person in the form of ropes and strips to pull them away from the power supply.

Electric shock often refers to the direct contact of the human body with a power source or high voltage.

Tissue damage and dysfunction caused by the transmission of electric current through the human body through air or other conductive media, and in severe cases, cardiac and respiratory arrest. High voltages above 1000 V (volts) can also cause burns. Lightning damage (lightning strike) falls under the category of high-voltage electrical damage.

There are many reasons for electric shocks, mainly lack of knowledge of safe electricity use, installation and maintenance of electrical appliances, wires not operating according to regulations, and hanging clothes on wires. High temperatures, high humidity and sweating make **surfaces.
