I. Characteristics of electrocution:
Electrocution due to direct contact with the power supply to the human body, a certain amount of current through the human body, resulting in tissue damage and dysfunction or even death, the longer the time of electrocution, the more serious the damage to the organism. Low voltage current can make the heart stop (or ventricular fibrillation), followed by respiratory arrest. High-voltage current due to the central nervous system strong stimulation, the first respiratory arrest, and then followed by cardiac arrest.
Second, the emergency organization
Emergency rescue team leader
Emergency rescue deputy leader:
Emergency liaison:
Site maintenance:
Emergency rescue:
Emergency rescue:
Responsibilities: in the first instance to organize the evacuation of people, rescue electrocuted people, maintenance of the site order and other work; Promptly report the scene situation to the leadership, according to the arrangement of timely delivery of the injured to the nearest hospital.
Third, emergency rescue equipment
Fourth, emergency procedures
(a) emergency response
In the workshop electrocution accident, the first witnesses on the scene should immediately call for help, and immediately cut off the power supply.
(B) emergency contact
Emergency contact group immediately call the emergency center (120 or 999), the content is as follows:
1, the name of the alarm, address, work unit, contact telephone number;
2, the exact geographical location of the electrocution accident;
3, the current situation and the surrounding casualties of the operators
4, patiently answer the "120" ambulance personnel's inquiries;
5, at any time with the emergency center personnel to keep in touch with and report the situation;
Emergency liaison group will be the current scene with the emergency rescue team leader to explain in detail, at the same time, by the emergency rescue team leader to the workshop leadership to report the following The content of the report is as follows:
1, the name of the reporter
2, the exact geographic location of the electrocution accident;
3, the current site conditions and casualties of the surrounding workers, etc.;
4, whether or not to report the situation and the current situation of the personnel;
5, listen to the leadership of the instructions.
(C) site maintenance
Site maintenance personnel according to the site surroundings, the use of conical traffic barrels to close the site. Closed the scene when the conical traffic barrels, pull a good cordon, protect the scene.
(D) emergency rescue
Emergency rescue team will be electrocuted with the power supply isolation: the method of separation from the power supply, should be based on the specific conditions of the scene, and decisively take the appropriate 'methods and measures, there are generally the following methods and measures:
1, if the switch or button from the electrocution site is very close, should be quickly pulled off the switch, cut off the power supply, and should be prepared for adequate lighting, in order to rescue. in order to rescue.
2, if the switch is far away from the electrocution site, can be used to insulated hand pliers or dry wood handle shovels, axes, etc. to cut off the wire.
3, when the wire on the electrocuted person or pressed under the body, can be used to dry sticks, boards or other tools with insulated handle, (hand-held insulated handle) will quickly pick the wire open.
4, if the person is electrocuted at a higher place, must take protective measures to prevent cut off the power supply after the electrocution of the person from the height of the fall.
5, if the electrocuted person's clothes are dry, and not tightly wrapped around the body, the rescuer can stand on a dry board, or dry clothes, dry scarves, etc. to wrap their hands tightly, and then use this hand to pull the electrocuted person's clothes, pull him away from the charged body.
(E) emergency rescue
Emergency rescue team based on different situations to take the right way for the electrocuted person to rescue:
1, electrocuted casualties such as lucid, it should be made to trip away from the place, close monitoring, do not stand or walk around for the time being.
2, electrocuted such as delirium, should be on the ground on their backs to trip away, to ensure that the airway is open, and with a 5-second interval to call the casualty or tap his shoulder to determine whether the casualty is losing consciousness. Prohibit swinging the casualty's head to call the casualty. Insist on proper resuscitation on the spot, and contact the hospital as soon as possible for resuscitation.
3, respiratory, heartbeat judgment of the electric casualty such as consciousness loss of life, should be within 10 seconds, with a look, listen, try to determine the casualty's breathing, if neither breathing and do not arterial pulsation, it can be determined that the respiratory heartbeat has ceased, we must take artificial respiration and chest compression at the same time the two methods of resuscitation.
(F) cardiopulmonary resuscitation, artificial respiration correct practice
1, in the medical personnel did not arrive at the scene, by the emergency rescue team and emergency ambulance team to cooperate with the electrocution of cardiopulmonary resuscitation and artificial respiration:
(1) to ensure that the environment is safe.
(2) In the hard flat (ground) on the position of supine, with forehead lifting chin method to open the airway, and clean the mouth of foreign bodies.
(3) Determine whether there is breathing or not, using the method of one look, two listen and three feel for 10 seconds: 1001, 1002, 1003, 1004 .... .1010
(4) If there is no breathing, first perform artificial respiration by blowing into the airway 2 times.
(5) Determine if there is a heartbeat (touch the aorta) for 10 seconds: 1001, 1002, 1003, 1004.... .1010, and observe the circulatory signs in the last 5 seconds.
(6) Judgment of cardiac arrest, immediately chest compressions. The location of chest compression should be located 3-4 centimeters above the lowermost part of the sternum, the median area of the sternum, and secondly, the compressor should keep the upper body leaning forward, take the hip joint as the fulcrum, straighten the arms, and vertically press the sternum downward for about 4-5 centimeters, then relax, and the frequency of compression should be 100 times per minute.
(7) Thoracic cardiac compression 30 times, artificial respiration 2 times, alternating. Pressure 10, 11, 12 ....20, 21 ....31, 32 .... .39,Blow 1,2...After 4 cycles of continuous operation, check respiration and heartbeat once for 10 seconds: 1001,1002,1003,1004.... .1010, checking respiration in the first 5 seconds, checking pulse and observing circulatory signs in the second 5 seconds.
(8) Resuscitation work, once started, can not be stopped in the middle of the process until the injured person woke up or the first aiders arrived at the scene.
V. Emergency treatment precautions
1, in the rescue process every few minutes with "a look, two hear, three feel" method to determine the respiratory and pulse condition of the electrocuted again, each time to determine the time shall not be more than 5 ~ 7 seconds.
2, before the arrival of medical personnel, the scene shall not stop rescue.
3, do not move the electrocuted casualty, such as the need to move the casualty in the rescue process, rescue interruption time should not exceed 30 seconds.
4, the electrocuted should be sent to the hospital using a stretcher, and in the back of the pad on the board, do not let the body of the injured curled up to carry, transfer on the way should continue to rescue.
5, regardless of which type, which way of electrocution first to immediately cut off the power supply or insulator, the first aiders do not directly contact the casualty to prevent themselves from being electrocuted, affecting the rescue work.
6, when the casualty from the power supply, check the casualty's general condition, especially respiratory and cardiac rhythm, found that respiratory and cardiac arrest, should be immediately implemented in situ rescue.
7, night electrocution, cut off the power supply will be at the same time to make the lighting loss of power, should consider cutting off the temporary lighting, such as emergency lights, etc., in order to facilitate rescue.
8, when the rescuer's color improved, lips gradually red, pupils narrowed, heartbeat and respiration back to normal, that is, indicating that the rescue is effective
