Frequently Asked Questions FORMALDEHYDE What is FORMALDEHYDE? Formaldehyde is a colorless, flammable gas with a distinct, pungent odor. It is also known as methanal, methylene oxide, oxymethylene, methylaldehyde and oxomethane. Formaldehyde is found in car exhaust, cigarette smoke, gas furnaces, and smoke from cooking appliances and open fireplaces. Our bodies also produce formaldehyde in small amounts by normal processes. Where can formaldehyde be found and how is it used? In the home, formaldehyde is found in food preservatives, cleaning products, cosmetic products, building materials and household products such as carpet. Newly constructed structures can release formaldehyde into the interior air for a long time after construction. Formaldehyde is used in industry to produce building materials and household products. It is also a by- product formed by burning and other natural processes. It can be present in smoke, some furniture and manufactured goods, gas stoves and kerosene space heaters. Formaldehyde is used to keep clothing and draperies from wrinkling. It is also part of some glues and adhesives, and is used as a preservative in some paints and coatings. How can people be exposed to formaldehyde? Most people are exposed to formaldehyde through vapors. In the home, formaldehyde can be present from cigarette smoke or from space heaters. Fireplaces, gas furnaces and appliances that are not vented properly can create vapors. House construction materials such as pressed wood products, hardwood, plywood paneling and fiberboard can all emit formaldehyde. Furniture can also contain this chemical. Homes without enough ventilation can have higher levels of formaldehyde. People who work with formaldehyde are at the highest risk of exposure. Exposure can be through direct contact or by working in areas where there is a moderate or high level of formaldehyde in the air. How does formaldehyde work and how can it affect my health? Breathing formaldehyde fumes causes watery eyes and burning in the eyes, nose and throat. Other symptoms are skin irritation and rashes, nausea, coughing and chest tightness, an upset stomach and trouble breathing. Breathing formaldehyde may cause an attack in people with asthma. Some people develop a sensitivity to formaldehyde. Formaldehyde causes cancer in animals. It is believed to cause cancer in humans. How is formaldehyde poisoning treated? There is no specific antidote or treatment for formaldehyde poisoning. Doctors can treat the symptoms and effects of exposure. What should I do if exposed to formaldehyde? The general public is exposed to harmless, low levels of formaldehyde daily. Persons exposed to high levels of formaldehyde, or exhibiting symptoms of exposure, should be quickly removed from the source. Seek medical attention if necessary. What factors limit use or exposure to formaldehyde? In the home, reduce exposure by having enough ventilation, especially when installing or using gas-burning appliances. During building projects, choose lumber, insulation and other products that contain only a small amount of formaldehyde. In the workplace, limit exposure by using an exhaust vapor hood, breathing equipment, gloves and goggles. Is there a medical test to show whether I’ve been exposed to formaldehyde? There is no specific test available for exposure to formaldehyde.
