What are the health risks of MDF?

Medium density fiberboard (MDF) is a manufactured wood product used in a variety of industries. The manufacturing process includes some chemicals that can be dangerous to humans, raising concerns about the health risks of MDF. There are two main concerns: exposure to the chemicals used to make it, and wood dust. By being aware of the potential risks, people can protect themselves when working with it.

To make MDF, a company grinds wood, softens it, and turns it into a fine powder. The powder is combined with resins and other binding agents and compacted into solid boards. A number of different woods can be used to make MDF, and the material is also sometimes treated to be fire-, water-, or stain-resistant. Many sawmills sell different types and widths for a variety of uses.

Toxic chemicals are one of the main health risks of MDF. The chemical of greatest concern is formaldehyde, which can aggravate asthma and other lung conditions, irritate mucous membranes, and cause contact dermatitis. Studies on this chemical also suggest that it is a probable carcinogen, and should generally be avoided. During the manufacturing process, personnel must be protected with respirators and suitable clothing. When cutting or working with MDF, nose, mouth, and eye protection should be worn. Finished products can also release gas, raising concerns about their use in the home. Fiberboard should never be burned except in facilities with adequate ventilation.

The second problem with MDF is wood dust, which is especially problematic for the respiratory tract, and can also be a possible carcinogen. Protective equipment will greatly reduce this health risk, and finished products rarely pose a dust risk as they must be properly sealed. MDF should always be cut and processed in well-ventilated areas to reduce the risk of dust inhalation.

The health risks of MDF should certainly be taken into account when using the material, but they should not rule out its use entirely. Especially for outdoor use, MDF can be versatile, strong and perfectly safe. However, the risks due to the possible release of gases should be a source of potential concern, especially for parents, since children are very sensitive to respiratory irritants. Employers also have a responsibility to ensure that their employees are protected on the job equipment.
