According to the general situation at the scene of the explosion, the explosion shock wave caused injuries to glass, gravel, etc., and the heat wave caused the most burns, scalds and burns.
How can friends at the scene give first aid? How can friends who are not injured protect themselves?
Step 1 Rest
No matter what kind of trauma, no matter whether it is serious or not, you should let the injured person lie down or sit down to rest.
Step 2 Raise the wound
Let the injured area be above the heart level, It can reduce the outflow of blood. If the wound is dirty, You can take clean cold water or warm water and rinse it gently, or you can take bottled water to rinse it, or you can use normal saline to clean the wound. Never use hot water, alcohol, iodine, mercurochrome, hydrogen peroxide or similar things to treat the wound. These potions will stimulate the wound and are really painful.
3. Direct oppression
Before stopping the bleeding, You need to wash your hands, This can prevent infection. If you don’t know the health status of the injured, It is best to wear gloves to prevent any possible infectious diseases. Hold the wound tightly for at least five minutes with sterilized gauze or clean cloth. If the bleeding slows down or stops, use a belt to fix the hemostat on the wound. If there are any signs of shock, stop the bleeding while calling 120.
4. Wound Foreign Bodies
If something is stuck in the wound or even stuck in the body, Don’t take it out, pulling it out may make the bleeding more serious. At this time, you need to cover the injured area with sterilized gauze, and be careful not to make the foreign body deeper. Bypass the foreign body, wrap the wound back and forth with a bandage in a  shape, and immediately see a doctor to remove the foreign body and treat the wound.
According to Tianjin residents, the nearest TEDA Hospital is overcrowded and the injured can go to Tanggu Hospital in the port for medical treatment and give necessary on-site first aid.
1. Do not tear off burning clothes and trousers forcefully: Quickly extinguish the flame and leave the fire scene. Clothes and trousers soaked in hydrothermal solution can be cut off after being washed with cold water, but do not tear off forcefully to avoid secondary damage.
2. Do not immerse large-area deep burns in cold water, so as not to cause sharp drop in body temperature and blood pressure and shock.
3. Pay attention to observe whether the injured person has shock manifestations (breathing, cough or exercise). If the injured person stops breathing or heartbeat, cardiopulmonary resuscitation should be implemented urgently.
4. Raise burned limbs as high as possible above the heart level.
5. To cover burn wounds, breathable and moist aseptic bandages, clean wet cloth or wet towel can be used.
Special reminder, if it is hand burn, must take off accessories such as rings while cooling down, otherwise swelling may cause finger necrosis.
Tap water or bottled water can be used to rinse, cold compress and soak the wound surface, or cold compress can be used with towels wrapped with ice cubes (ice cubes cannot be directly applied to the wound surface).
The duration of cold therapy is preferably 10 to 15 minutes or until the wound surface does not feel pain or the pain is significantly relieved.
Cold therapy can reduce temperature, relieve pain and relieve local swelling.
Cotton or other dressings that can stick to open wounds on the affected part should not be used, and the covering should not be too tight. Covering with aseptic gauze can keep wounds clean, reduce pain and protect skin blisters.
Superficial burns are generally cured without further treatment.
After healing, the affected part may have pigmentation, that is to say, there will be differences in color with the surrounding skin. Attention should be paid to observe whether there are signs of infection on the wound surface. If the wound surface pain intensifies, redness, fever, swelling or exudation, seek medical treatment as soon as possible.
A. Do not squeeze the affected part and tear the blister by yourself. Because you have bacteria on your hands, you cannot perform aseptic operations like a doctor. Squeezing or tearing the blister is more likely to cause wound infection.
B. Do not smear egg white, butter or ointment on the affected part to avoid infection;
C. Do not directly apply ice to the wound surface! Directly placing ice cubes at the wound surface can cause further damage to the wound surface due to a sharp drop in temperature.
If it is serious, or injuries to hands, feet, face, groin, buttocks or major joints, etc., it must be treated as deep burns and emergency medical treatment is required.
Injection of tetanus vaccine: Whether burn patients are complicated with tetanus depends not on the size of the burn area, but on the depth of the burn and the condition of the injury. Any person with deep burn or serious pollution during injury must take preventive measures against tetanus.
It is suggested that nearby residents should not join in the fun and close the doors and windows, because the nature of the explosion has not been determined and whether there is any dispersion of harmful gases is unknown. Therefore, everyone should reduce going out and maintain road traffic while protecting their own safety.
