AC voltage exceeding 65 volts can harm the human body, and high-voltage wires falling to the ground can cause electric shock within a 10 meter radius. The voltage of lightning can reach 100 million volts, hitting the human body can immediately cause carbonization and blackening.
The first aid for electric shock victims should be done every second. Patients who experience respiratory or cardiac arrest are in a very critical condition. At this time, emergency treatment should be carried out and emergency contact should be made to send the patient to the nearest hospital for further treatment; During the process of transferring patients to the hospital, rescue work cannot be interrupted.
1. Turn off the power switch, cut off the power, and then rescue. When the power cannot be turned off, you can use wooden sticks, bamboo poles, etc. to lift the wires away from the person’s body. If the electric wire or other live electrical appliances that cause electric shock cannot be separated, a dry rope should be used to wrap the person who has been electrocuted and drag them away to remove the current. It is best for rescuers to wear rubber gloves, rubber sports shoes, etc. Do not use your hands to pull an electric shock victim, and do not forget your own safety just because you are eager to save someone.
2. If the injured person is conscious and breathing and heartbeat are autonomous, they should be placed on the ground, closely observed, and temporarily not stand or walk to prevent secondary shock or heart failure.
3. When the injured person loses consciousness, immediately call an ambulance and try to wake them up. For those who have stopped breathing and have a heartbeat, lie down on the ground, loosen the buttons, clear the airway, and immediately engage in mouth to mouth artificial respiration. If the heartbeat stops and breathing is present, immediate chest compressions should be performed.
If it is found that the heartbeat and breathing have stopped, resuscitation measures such as mouth to mouth artificial respiration and chest massage should be taken immediately (except for a few confirmed electrocuted victims), and the general rescue time should not be less than 60-90 minutes. Until the person who has been electrocuted is restored to breathing and heartbeat, or until it is confirmed that there is no hope of survival. It is best for two people to perform mouth to mouth artificial respiration and chest compressions separately during on-site rescue, in a ratio of 1:5, that is, one artificial respiration and five heart compressions. If there is only one person being rescued on site, perform chest compressions and artificial respiration in a ratio of 15:2, that is, perform chest compressions 15 times first, and then mouth to mouth artificial respiration 2 times, alternating in this way. The rescue must be persisted until the end.
Attention:
When dealing with electric injuries, attention should be paid to the presence of other damages. If an electric shock causes it to bounce off the power source or fall from high altitude, it often leads to complications such as traumatic brain injury, hemopneumothorax, visceral rupture, limb and pelvic fractures, etc.
2. Do not apply ointment or unclean dressings to the wound or surface of electric burns, but wrap it with clean dressings or wait for a doctor’s treatment after being sent to the hospital.
During on-site rescue, do not move the injured person randomly. If it is necessary to move, the rescue interruption time should not exceed 30 seconds. When moving an injured person or taking them to the hospital, in addition to lying flat on a stretcher and placing a flat and hard wooden board on the back, rescue should continue. For those who have stopped breathing and heartbeat, artificial respiration and chest compressions should continue. Treatment cannot be stopped until medical staff at the hospital take over.
When encountering lightning or thunder, quickly go to the nearest building to avoid it. When there is no place to hide in the wild, take off metal items such as watches and glasses, find low-lying areas to hide, and never take shelter under large trees. Do not stand on high walls, under trees, near electric poles, or near antennas.
