Understanding Asbestos
Asbestos refers to a group of minerals that were commonly utilized in acoustic ceilings, roofing materials, vinyl flooring, plaster walls, and duct insulation due to their beneficial properties. The regulated types of asbestos include Anthophyllite, Crocidolite, Tremolite, Chrysotile, Amosite, and Actinolite. Asbestos deposits are found worldwide, with active mining operations in Australia, South America, Canada, and South Africa.
Due to concerns over the health effects of exposure to carcinogenic asbestos fibers, the Environmental Protection Agency (EPA) banned asbestos in the mid-1970s. Asbestos exposure has been linked to serious health conditions, including asbestosis, mesothelioma, and lung cancer. Asbestosis is a lung disease characterized by scarring, leading to reduced lung function. Mesothelioma, a cancer affecting the lining of the lungs, chest, and abdominal wall, has a latency period of 15-50 years. Asbestos exposure can also increase the risk of lung cancer and gastrointestinal tract cancers.
Hazards of Asbestos
Asbestos consists of microscopic fibers that can become airborne when disturbed, whether through renovation construction or more catastrophic events like fires. Inhaling these fibers can lead to severe health problems. Although researchers have not determined a safe level of exposure, the concentration of fibers and duration of exposure directly impact the risk of asbestos-related diseases.
Asbestos-containing materials, such as vinyl floor tiles, do not pose a hazard when in good condition. However, if these materials are damaged or disturbed, the asbestos fibers can separate and become airborne, posing a significant health risk.
The Impact of Fire on Asbestos
When exposed to high heat, such as in a fire, asbestos becomes brittle, breaks apart, and can be released into the air, intensifying the health hazard. Therefore, it is crucial to rely on experienced professionals for asbestos cleanup after a fire. Licensed fire damage asbestos removal professionals possess the necessary training and equipment to safely and correctly handle such situations.
During a fire, asbestos fibers may be inhaled by coworkers, employees, first responders, cleanup workers, and anyone else exposed to the site, further increasing health risks. The smoke from fires is already hazardous due to its composition of carbon dioxide, carbon monoxide, water vapor, fine particulate matter, and various organic and non-organic substances. The addition of asbestos fibers to this mix significantly compounds the dangers.
Proper Steps for Asbestos Cleanup
If you suspect or discover asbestos after a fire, it is essential to maintain a safe distance, especially if the site is still smoldering and producing smoke. While wearing protective gear can mitigate risks, handling asbestos requires specialized training. Therefore, it is recommended to leave the cleanup to professionals.
Professional cleanup crews, like our experts at CRC, should be called in once the fire has been extinguished. These professionals will thoroughly examine the site, paying close attention to roofing materials, ceiling tiles, insulation, asphalt, and flooring, as these areas are most likely to contain asbestos after a fire.
Discovering asbestos after a fire can be a challenging situation, but by relying on professionals like CRC, you can rest assured that your commercial space will be safely restored and free of asbestos. If you find asbestos after a fire, do not hesitate to contact CRC for expert assistance.
