Products and Locations
Asbestos was used in all types of pre-1980 residential and commercial construction, such as in floor and ceiling tiles, boiler rooms and around insulated pipes.
Part of a carpenter’s job description is remodeling commercial buildings and houses. Many of these renovations are made on structures that were built when asbestos was widely used. That means carpenters must cut away asbestos-containing molding and insulation and remove floor and ceiling tiles that may have had asbestos added to them to make them fireproof and soundproof. When these products are cut or disturbed in any way, asbestos dust is released into the air and onto the workers themselves.
Normal face masks do not protect the wearer from asbestos fibers in high concentrations. That is why regulations from the Occupational Safety and Health Administration (OSHA) mandate the use of respirators.
Carpenters who worked on construction projects before 1980 often handled asbestos sheets and were required to cut them into sizes that were appropriate for different applications. This also resulted in carpenters being covered in asbestos dust.
In a 1983 study, researchers evaluated 127 buildings throughout the U.S. and discovered that more than 50 percent of them had chrysotile-containing fireproofing insulation sprayed on ceilings.
At the start of renovation activities by various workers, including carpenters, average asbestos fiber concentrations at workers’ breathing levels were less than 2 fibers per cubic centimeter.
However, once the removal of the sprayed-on materials began, the workers were exposed to an average of 16.4 asbestos fibers per cubic centimeter when the material was left dry and removed. When the material was wetted down before removal, the airborne fiber concentrations were less than 2 fibers per cubic centimeter.
In a 2010 case study published in a Danish medical journal, physicians evaluated a 55-year-old carpenter who developed a pleural effusion (buildup of fluid) in the right lung in 2000 and in the left lung in 2003. He also developed pleurisy, an inflammation in the lining of the lungs that causes extreme pain during breathing. The physicians could not find any medical explanations for the condition.
However, they did determine that the carpenter was exposed to asbestos for six months in 1971 while working with roof sheets made of asbestos cement. The physicians concluded that the carpenter’s pleurisy and pleural effusions were caused by the exposure.
The family of deceased carpenter Searr Delcambre filed an asbestos injury lawsuit in 2008 against the A.O. Smith Corp. and 67 other companies. The family claimed Delcambre developed an asbestos-related disease from working around the products manufactured by these companies.
The lawsuit alleged the named defendants were negligent for not adequately testing their asbestos-containing products before widely distributing them and for not warning consumers of the dangers of asbestos exposure.
U.S. Gypsum Company manufactured asbestos-containing roofing, plaster, cement and adhesives. Its bankruptcy reorganization plan included an asbestos trust.
Congoleum Corporation manufactured asbestos floor products. Its bankruptcy reorganization plan also included an asbestos trust.
Georgia-Pacific Company manufactured asbestos joint compound and drywall adhesive. It has been named in a huge number of asbestos occupational injury suits.
