1) SMF or synthetic mineral fiber is employed in products for sound and heat insulation. Although considerably less toxic than both asbestos and lead SMF can cause irritation to the skin, eyes, nose and throat in some people. Plus, SMF is basically made up of a mixture of fiberglass, rock wool and ceramic; fiberglass has been found to be a risk factor for lung cancer. We recommend residential contractors to wear their safety equipment like eye goggles and respirators when proceeding in a place with SMF exposure.

2) The second is commonly known but not always expected to be found.  Another exceedingly common but less potent irritating agent is wood dust that contains formaldehyde for preservation purposes. A good percentage of the population is sensitive to formaldehyde with some people more sensitive than others. This type of wood dust can, once again, irritate the eyes or more commonly the nose. It can pretty much irritate any mucosal surface. Respirators and protective gear should be adorned when dealing with wood paneling or areas where wood dust is in high concentration.

3) We already established that lead is a poisonous material which can even affect the brain if the poisoning becomes too severe. What many people don’t realize is that lead has an insidious way of finding its place in things that are apparently innocent and – in this case – colorful. That’s right: lead paint is a major health hazard that is overwhelmingly overlooked. Steel beams that have been coated with lead paint, when torched, release lead particles that can be detrimental to health.   If you anticipate being on the job site with the demolition contractor you hired, you will be required to not only wear masks but also gloves and protective clothing when torching lead-coated steel bars.
