3.2. 1. People fall from the sky during the maintenance of tower crane;
1). Lie the injured person on his back in a proper position at the scene. If he stops breathing, he should be given heart massage and artificial respiration immediately, and then stop bleeding and bandage the wound. It is believed that when the heart stops beating, hold the chest of the injured person's heart with your hands and keep pressing the heart until the heart beats. In case of limb fracture, the fracture site should be leveled, and the main fracture site should be tied and fixed with a rope, and then sent to the hospital for treatment.
2) Injuries caused by falling objects during tower crane maintenance: First, stop bleeding and bandage the wounded, such as respiratory asphyxia, and give artificial respiration until breathing is normal. If the injury is caused by head vibration (wearing a helmet is easy to cause concussion), the head should be iced or wrapped with a wet towel to keep the wounded awake. According to the feelings of the wounded, do a good job of nursing and send them to the hospital.
3.3. The tower crane accident emergency rescue measures in use:
3.3. 1. Tower crane collapse and personal injury accidents caused by natural disasters:
1). Generally, construction is not carried out during typhoons and snowstorms, and there are no personnel activities in buildings with personnel activities within the radius of gyration of tower cranes, mainly due to equipment loss. When cleaning up the equipment wreckage, pay attention to the injury caused by the collapse accident. Check whether there are any dangerous tower components first, and then cut and dismantle the dangerous components after reinforcement. In case of earthquake during construction, first evacuate the people around the tower crane, turn off the power switch, and inform the driver to protect himself with the walkie-talkie. First, protect his head from impact. Protect his head with safety helmet, clothes and sanitary napkins. Then observe the falling direction of the tower crane, and keep the body in an elastic state when the tower falls to the ground to reduce the harm to the body. After the tower crane landed, the wounded were rescued first and sent to the hospital after nursing.
2) Collapse of the tower crane in normal use: once the personnel present find that the tower crane may collapse or is about to collapse (the tower crane collapses slowly at first, and the center of gravity changes with the decrease of the inclination angle, and the collapse speed is accelerated), the witnesses should immediately call the personnel present to avoid danger and hide, inform the project manager and the general manager of construction in time, and rescue the operators who fall, fall and scratch.
3) Falling objects injure people: Falling objects injure people mainly. To rescue the wounded, first check the injured part, treat the bleeding and fracture wounds according to the treatment method, and then send them to the hospital.
4). Emergency rescue after group crane collision: The incidents caused by tower crane collision include boom damage and wire rope damage. In severe cases, hanging objects are scattered and hurt people, and tower crane collision accidents hurt people. First rescue the wounded, and then send them to the hospital according to the treatment method. Equipment accident is to check the boom and wire rope, repair the boom and replace the wire rope according to the damage, so that the tower crane is in a safe state before use.
3.4. On-site care of the injured:
3.4. 1. Injury accidents during installation and use of tower crane mainly include traumatic bleeding, fracture and internal injuries. According to different nursing methods, and then sent to the hospital.
3.4.2. Stop bleeding on site:
1). Compression hemostasis method: first raise the injured limb, please clean the wound, apply hemostatic drugs externally, and then cover the wound with sterile gauze or cotton pad. Clean handkerchiefs, towels or other cotton cloth can be used instead, and then bandage or cloth can be used to stop bleeding.
2) Hemostasis near the heart due to acupressure artery bleeding: According to the bleeding site, the acupressure facial artery, common carotid artery, subclavian artery, temporal artery, femoral artery, anterior tibial artery and posterior tibial artery were used to stop bleeding.
3) Elastic tourniquet hemostasis method: When the arterial wound of the limb bleeds, and the general hemostatic dressing can't achieve the hemostasis effect, first raise the limb to make the venous blood fully return, then place an elastic tourniquet near the wound site, and place a sterile gauze cotton pad between the tourniquet and the skin. The tourniquet must be fastened, and the arteries in this place should be pressed and fastened, so that they can be sent to the hospital as soon as possible in a short time.
4) Bandage and fixation: Cover the wound with sterilized cotton products, and then bandage it with bandages or cloth strips.
3.4.2. On-site treatment of fracture, respiratory arrest and cardiac system beating: according to Article 3.2. 1. 1 of this plan.
3.4.3. Treatment of the wounded:
1). After on-site hemostasis, dressing and fixation, the wounded should be transported correctly and transferred to the hospital for emergency treatment as soon as possible. It should be noted that local pain, swelling, dysfunction or abnormal changes occur after limb injury, suggesting the existence of fractures. It should be transported after the tourniquet is bandaged and fixed, so as to avoid the displacement of the broken end of the fracture due to handling vibration and aggravate the trauma.
2). When transporting the wounded with severe trauma accompanied by massive hemorrhage and shock, transport them on their backs, with ice packs or ice caps on their heads, and avoid shock as much as possible on the way.
3). When dealing with the wounded who fall from a height, it is necessary to make the wounded lie flat on the hard board for processing because of the possibility of spinal injury. It is forbidden to carry the wounded only on the shoulders and legs or carry the wounded on one shoulder to transfer the injured spine.
3.5. On-site accident inspection and aftermath:
3.5. 1. If the tower crane collapses and falls, the structural strength of the damaged part shall be tested by a qualified testing unit.
