Emergency treatment of chemical body surface burns
Dealing with chemicals, once the protection is not good, it will inevitably spill the clothes or the skin of the body. At this time, it should be dealt with quickly, otherwise it will burn the skin and be hurt.
Immediately take off the clothes soaked with strong alkali and strong acid.
Immediately flush the burn with plenty of tap water or water. Rinse repeatedly until it is clean. It usually needs to be rinsed for 15 to 30 minutes. It can also be rinsed with warm water. Do not use acidic (or alkaline) liquid to neutralize without rinsing, so as not to cause a large amount of heat to increase the degree of burns.
If it is burned by quicklime, electro-lime, etc., it should be partially wiped clean and then rinsed with plenty of water. Do not rinse or soak in water directly before it is cleaned, so as to avoid heat and heat and increase burns. Neutralize with a neutralizer and rinse off with water. If it is burned by a strong base, it can be neutralized with vinegar, 3% to 5% acetic acid, 5% dilute hydrochloric acid, 3% to 5% boric acid. If it is burned by strong acid substances, it should be neutralized with 5% sodium hydrogencarbonate, 1% to 3% ammonia water, lime water clear solution, etc.
First aid for chemical eye burns:
Acid or lye is splashed into the eyes. Because these two substances are highly corrosive, they cause different degrees of chemical burns to the cornea and conjunctiva, causing acute inflammation. At this time, do not rub your eyes with your hands. Rinse immediately with plenty of water. When flushing, you can blindly flush with water. You can also dip the eyes into the water, open your eyes or separate the upper and lower eyelids by hand, and swing your head. Or turn the eyeball for 3 to 5 minutes. Water should be changed frequently to thoroughly clean residual chemicals.
If granular chemicals enter the eye, wipe them off immediately and rinse with water repeatedly. Injury to eye wash should be carried out immediately, the sooner the better, the more thoroughly the better. Do not delay the timing due to excessive emphasis on water quality, thus increasing the degree of injury.
First aid in wearing chemical fiber clothing burns:
After wearing a chemical fiber clothing burn, the burning matter should be quickly and properly removed. Chemical fibers (such as vinylon, polyester, acrylic, cotton, etc.) are high molecular compounds. In the case of combustion explosion, the temperature is generally above several hundred degrees, the chemical fiber will melt immediately, the temperature of the molten material can reach 200-300 ° C or even higher, adhere to the human skin, not easy to fall off, and must cause serious injury (burn or poisoning). After wearing a chemical fiber clothing burn, it must be quickly and properly cleaned without leaving gray marks. Natural fibers (cotton, wool, hemp, silk, etc.) are different. Their melting points are higher than the decomposition point. Once they are subjected to high temperature, they will be decomposed or charred without melting. Even if the overalls are burned, they will not stick to human skin. Easy to take off or put out.
