Formaldehyde Poisoning is a disorder brought about by breathing the fumes of formaldehyde. This can occur while working directly with formaldehyde, or using equipment cleaned with formaldehyde. Major symptoms may include eye, nose, and throat irritation; headaches; and/or skin rashes.
The severity of the signs of formaldehyde poisoning depends on the amount of formaldehyde inhaled or ingested by a person. Proper identification of formaldehyde poisoning symptoms should be done to treat it at the earliest.
