 CFS - NORMI Certified Formaldehyde Screener


The Certified Formaldehyde Screening program is an online or self-study course that trains the IAQ Professional in techniques to screen for and then reduce formaldehyde contamination levels in indoor environments. The class covers the sources of formaldehyde, the deleterious health affects, and the solutions recommended to lower levels and manage the indoor air quality environment. This class is based on information provided by the US Department of Health and Human Services and other resources that are included in the class online or on CD.

"Formaldehyde is a colorless, flammable gas at room temperature. It has a pungent, distinct odor and may cause a burning sensation to the eyes, nose, and lungs at high concentrations. Formaldehyde is also known as methanal, methylene oxide, oxymethylene, methylaldehyde, and oxomethane. Formaldehyde can react with many other chemicals, and it will break down into methanol (wood alcohol) and carbon monoxide at very high temperatures.

Formaldehyde is naturally produced in very small amounts in our bodies as a part of our normal, everyday metabolism and causes us no harm. It can also be found in the air that we breathe at home and at work, in the food we eat, and in some products that we put on our skin. A major source of formaldehyde that we breathe every day is found in smog in the lower atmosphere. Automobile exhaust from cars without catalytic converters or those using oxygenated gasoline also contain formaldehyde. At home, formaldehyde is produced by cigarettes and other tobacco products, gas cookers, and open fireplaces. It is also used as a preservative in some foods, such as some types of Italian cheeses, dried foods, and fish. Formaldehyde is found in many products used every day around the house, such as antiseptics, medicines, cosmetics, dish-washing liquids, fabric softeners, shoe-care agents, carpet cleaners, glues and adhesives, lacquers, paper, plastics, and some types of wood products. Some people are exposed to higher levels of formaldehyde if they live in a new mobile home, as formaldehyde is given off as a gas from the manufactured wood products used in these homes." US Dept. of Health and Human Services

Once the student completes this class, he is expected to pass a test evidencing his complete understanding of the issues surrounding formaldehyde and the techniques used to reduce formaldehyde levels on a permanent basis. After the student has completed the online quiz, he is encouraged to activate his membership (inactive membership is included in the cost of this class) by going to so that he can take advantage of the benefits offered by NORMI to ACTIVE Members. Continuing Education every week is offered at NO CHARGE to all ACTIVE Members and a listing at the website is provided so that potential customers may be able to locate a CFS in their specific area of the county.
