Since hydrofluoric acid accident has a sudden, long duration, a wide range of victims, first aid and decontamination difficult features to eliminate and control the impact and harm caused by the accident, it is bound to affect about the production, transportation and other living and normal activities. In particular, some international cities, once large chemical accident, would have strong repercussions in the international arena, with serious consequences in terms of political, economic and cultural exchanges.

Hydrofluoric acid has a corrosive effect on the human body, could easily lead to chemical burns. Fire burns burns burns and general corrosion caused by different materials, often do not feel pain at the beginning, but the organization has found burns. So to reach the skin corrosives, shall promptly take emergency measures.

Chemical skin burns should be immediately removed from the scene and quickly removing contaminated underwear, socks, etc., and with plenty of water wash the wound 20-30 minutes (strong chemicals to be longer) to dilute the toxic substances to prevent further damage and absorption through the wound. The fresh wound do not arbitrary use ointment or painted red syrup, gentian violet, do not use dirty cloth wrapped; rinse with plenty of water when phosphorus burns, soak or cover the wound with a clean, damp cloth multilayer.

Precautions:

1.Sulfuric acid, fuming sulfuric acid, nitric acid, fuming nitric acid, hydrofluoric acid, sodium hydroxide, potassium hydroxide, calcium hydroxide, hydroiodic, hydrobromic acid, chlorine acid contact with skin, immediately wash with water. As already rotting skin, rinse with water at least 20 minutes, and then escorted to hospital for treatment.

2.In the field a simple first aid, general patient should be promptly sent to hospital. Escort shall provide reasons for hospital burns or poisoning, chemical name; such as chemical composition is unknown, will have to bring a sample of the material or vomit to the hospital for testing.

3. On-site ambulance participate should pay attention to self-protection, such as the time is not long, to have a water-soluble poison (chlorine, ammonia, hydrogen sulfide, etc.), can be used wet towel over his nose and mouth for simple protection, may wear protective conditions masks and other protective equipment.

4.At the same time save the patient, we should try to stop leak, prevent the spread of hydrofluoric acid and poison.
