Exposure to asbestos wall board can lead to serious health risks, including respiratory issues such as lung cancer, mesothelioma, and asbestosis. It is important to handle asbestos-containing materials with caution to prevent inhalation of asbestos fibers.
No, modern gypsum board does not contain asbestos.
Older cement board may contain asbestos, and then it is properly called "asbestos cement board." Cement board more recently manufactured should not contain asbestos. The only way to know whether a particular cement board does or does not contain asbestos is to ask the manufacturer (if you know who made it) or have a sample collected from it by a qualified sampling technician and have the sample analyzed by a qualified laboratory.
No, gypsum has a natural fire resistance due to the combined molecules of water which it contains. National Gypsum has never used asbestos in its wallboard products. However, it did at one time use asbestos in some of its sprayed-on fire proofing products. That ingredient was removed from their formulation several decades ago.
Some fibrous cement board contains asbestos and some does not. It depends on when and where it was manufactured. The only way to be certain is to have it tested by a qualified laboratory.
Yes, Villaboard, a type of fibrous cement board used in construction, commonly contained asbestos in its formulation during the early 1970s. Asbestos was widely used in building materials for its fire-resistant properties until its health risks became more widely recognized. Consequently, many older buildings using Villaboard may still pose asbestos exposure risks if the material is disturbed or damaged.
Using a warped cutting board in the kitchen can pose risks such as uneven cutting surface leading to accidents, difficulty in chopping food properly, and the potential for bacteria to accumulate in the crevices.

MDF board is made from wood fibers and resin, which can release formaldehyde gas. Prolonged exposure to formaldehyde can be harmful to human health, causing respiratory issues and irritation. It is important to use MDF board in well-ventilated areas and consider alternatives if concerned about potential health risks.
Asbestos-cement wallboard looks like any other cement board product. Only analysis by a qualified lab can tell the difference.
