7. Self-Help, first aid and other basic knowledge after a traffic accident, as well as knowledge of Common Hazardous Chemicals

I. Self-help and first aid knowledge of the wounded:

1. When rescuing the wounded, they should save their lives and then cure the injury.

2. When an injured person is under a wheel or cargo, the correct method is to move the vehicle and take appropriate ambulance measures to remove the goods.

3. When the injured cannot get off the bus on their own, try to remove them from the car and try to avoid secondary injuries.

4. When many wounded need to be taken to the hospital in case of serious or serious accidents, those in a coma should be taken to the hospital first. When handling a person who is in a coma or who is in danger of suffocation, he/she should adopt the method of lateral prone. Measures should be taken to warm up the wounded in shock relief to prevent heat loss. If the wounded do not breathe, the wounded should be given mouth-to-mouth artificial respiration immediately.

5. Stop the bleeding before rescuing the wounded. In case of emergency, the wounded must use the compression method to stop the bleeding, and then use other methods to stop the bleeding.

6. When the wounded are bleeding from the main artery, use the finger pressure method to stop the damage. Use the thumb to compress the wound's near-cardiac artery and block the arterial movement to quickly stop the damage.

7. Total carotid artery compression and damage control method, which is often used in the treatment of major hemorrhage of the wounded cervical artery, but other methods of damage control are ineffective.

8. When the wounded have bleeding in the upper extremity or lower leg, and there is no fracture or joint injury, you can use the flexion and pad method to stop the damage (fixed in the armpit or elbow ).

9. Bandage, triangle towel, and hemostatic belt are commonly used for damage control. When the wounded are bandaged and knotted with a bandage, do not be above the wound or behind the body to avoid being uncomfortable during sleep. If no bandage is available for the wounded, replace the bandage with a towel, handkerchief, bed sheet, long cylinder nylon so, etc. The hemostatic belt uses an elastic rubber hose and rubber belt to stop the damage. The upper extremity is attached to 1/3 of the wounded's upper arm, and the lower extremity is attached to the middle of the thigh. Use a hemostatic belt to stop the bleeding of the wounded. Be sure to tighten it. If it is not tight, there is still blood flow in the deep artery.

10. The correct measure for saving the wounded in the whole body is to quickly put out the flame on the clothes, spray cold water on the body, and take off the burned clothes. When the Burned Wounded are thirsty, they can drink a small amount of light saline.

11. First aid measures to help the wounded with harmful gas poisoning are to quickly move the wounded to a place with fresh air.

12. The upper and lower joints of the wounded limbs with fracture exposed on the boneless end should be exceeded when fixed with splices, wooden sticks, branches, etc. The wounded who have joint injury (sprained, dislocation, and fracture) should avoid activities. When rescuing the wounded with spinal fractures, use a triangle towel to fix the spine and keep the spine stable. When the thigh, calf, and spine of the wounded are fractured, they should be fixed on the ground and should not be moved freely. The fixed injury of the wounded with a fracture should be fixed to the two ends of the fracture and the upper and lower joints.

2. Knowledge of common hazardous chemicals:

1. hazardous chemicals are characterized by explosion, flammable, toxic, corrosive, radioactive, etc.

2. Explosives refer to substances and articles with overall explosion risks. Gunpowder, explosives, and explosives are explosives.

3. Matches, sulfur and red phosphorus are flammable solids.

4. When fighting fires that are prone to corrosive vapor or toxic gases, the saving personnel should wear gas masks and corresponding protective products, and stand in the upper hand to save.
