Safety manual for the use of organic chemicals

Formaldehyde

A) physical and chemical properties and use of colorless, spicy spicy smell of gas. Density: 1.07, boiling point: -19.5 ℃, spontaneous combustion point of 300 ℃. Flash point 60 ℃. Explosive limit: 7 to 73%, its 37% aqueous solution (about 10% methanol) is "Formalin" is a colorless, irritating liquid that is volatile at room temperature. For the manufacture of phenolic resin, urea-formaldehyde resin, fur processing, medicine, Organic Chemicals paint and so on. But also as a preservative.

(B) toxic performance coagulation protein.

After contact with the skin, mucous membrane has a strong stimulating effect.

This product is suspicious human carcinogens. Maximum allowable concentration: 3 mg / m3

(C) the impact of short-term exposure to inhalation: inhalation of formaldehyde can cause rhinitis, sore throat, loss of smell, cough, chest tightness and bronchitis, severe cases of laryngospasm and pulmonary edema and other symptoms. Eye contact: Formaldehyde steam causes eye burning, tears, conjunctivitis. Skin contact: May cause contact dermatitis.

(5) fire and explosion This product is flammable, is a Class B fire hazard substances, should be prohibited fire smoking. At 600 ° C, the steam and air mixture is explosive. Fire when the water spray cooling containers, a large number of water can be used to extinguish the fire.

(6) chemical reactivity This product will be in the natural state of polymerization, so industrial formaldehyde as an inhibitor. Formaldehyde reacts with strong oxidizing agents. Organic Chemicals With hydrochloric acid reaction, sometimes the formation of very toxic dichloromethane.
