About Formaldehyde

Formaldehyde is commonly used in fertilizers, glues, plywood, fibrewood, particleboard (used in sub-flooring, shelving, cabinetry and furniture) and certain types of insulation. It is also a by-product of combustion (gas stoves and kerosense space heaters) and certain other natural processes.

 

The dangers of Formaldehyde

The Environmental Protection Agency (EPA) has classified formaldehyde as a probable human carcinogen.
Formaldehyde is a colorless, strong smelling gas. Exposure to formaldehyde vapours (above 0.1 parts per million) can cause irritation to the eyes, nose and throat. It can also damage the skin of anyone who comes in close contact with the chemical. Its level of irritation is such that it can cause asthma attacks in especially sensitive people.
The chemical has also been linked to respiratory allergies in children.

 

Preventing Formaldehyde exposure

Be vigilant when buying wood products. Try and buy exterior-grade wood when using wood in the home. The formaldehyde coating in exterior-grade is often more stable than its interior equivalent.
When buying wood furniture that use particle board (and many do) make sure it is coated or laminated.
Homes with significant amounts of pressed wood products can have formaldehyde levels of 0.3 parts per million.
To prevent formaldehyde vapours from circulating in the air currents of your home, make sure you ventilate your surroundings adequately.
