As a plumbing or mechanical contractor, you might think the Occupational Safety and Health Administration’s proposed silica standard has nothing to do with you. But are you sure? Have you ever had to cut through concrete or tile to install pipe — or drill holes in concrete to hang ductwork? Everyone who works in the construction industry needs to be aware of potential exposure to airborne crystalline silica.
Silica is found in many materials common on construction sites, including concrete, masonry, brick, block and stone. The dust created by cutting, grinding, drilling or otherwise disturbing these materials can contain respirable crystalline silica. Inhaling this dust can result in serious illnesses, which are sometimes fatal. These illnesses include silicosis, lung cancer and other respiratory diseases. It only takes a small amount of airborne silica dust to create a health hazard.
