affects the central nervous system, has the annoying, cauterizing and sensitizing properties.
Symptoms and signs of poisoning
In acute inhalation poisoning: conjunctivitis, acute bronchitis, pulmonary edema until, gradually increasing signs of central nervous system (dizziness, anxiety, staggering gait, seizures).

under the action of vapors of formalin (for example, workers employed by manufacturer of synthetic resins), as well as through direct contact with formalin or its solutions are observed, especially in the first days of operation, expressed dermatitis of the face, forearms and hands, nail infections (theirbrittleness, softening).There are dermatitis and eczema, allergic nature.After suffering poisoning increased sensitivity to formalin.There is evidence of an adverse effect on specific functions of the female body.

indicated: oxygen inhalation, heart, respiratory stimulants (lobelia, tsititon), sedatives (valerian tincture, bromine).In the future, with symptoms of respiratory irritation of the mucous - alkali and oil inhalation, codeine, dionin, mustard.When eye irritation - copious water washing, cold lotions, instillation of 1-2 drops 0.5% novocaine solution with the addition of 8-10 drops epinephrine (1: 1000) at 10 ml.If laryngeal edema - intubation, tracheostomy.
If poisoning by ingestion - copious gastric lavage (probe lubricated) 2-3% solution of ammonium carbonate, acetate or chloride (the binding of formaldehyde in the form of hexamine).Drinking mixture: 2% solution of ammonium salts with 10-20% urea.Ammonia-anise drops (15-20 drops).Enveloping (raw eggs, beaten egg white, slimy decoctions).Saline laxatives, excessive administration of fluids (prevention of renal damage).Vitamin K inside.When you stop breathing - CPR.
Skin - wash immediately with water, better 5% solution of ammonia.
disability When expressed phenomena of intoxication and persistent transfer to another job - with no exposure to toxic substances.
