Experiments we often contact with all kinds of chemicals, such as strong acid, strong alkali solution, strong chemical toxicity, as well as exposure to high temperature object, such as are electric stove heating vessels or molten sample taken from the muffle furnace, etc., will cause harm to the skin, light person skin is dry, peeling, tickling, followed by redness and swelling, blisters, herpes, scar, etc. However, in general, laboratory workers only use a single plastic glove and woven glove, which is not enough to protect the hand. Therefore, the correct selection and use of gloves is an important measure to prevent hand injury.

Contact with hydrofluoric acid gas, skin itching, pain, eczema and various dermatitis, petroleum hydrocarbons such as gasoline on the skin fat soluble and irritating, dry skin, cracking, some people will have erythema, blisters.
