Asbestos Dangers - During and After Fires

Asbestos Dangers - During and After Fires

Mesothelioma & Asbestos Cancer Resource Center

There are many factors that play into the dangers of fires. Besides being exposed to the obvious immediate hazard as the fire itself, smoke inhalation of carbon monoxide poison, and collapsing buildings, there is a less obvious factor that may be more dangerous—asbestos exposure.

What is asbestos? Asbestos is a naturally-occurring mineral that is a known carcinogen. This fiber consists of long, thin fibrous crystals and may be mixed with other substances in order to resist heat, electricity and chemical damage. Due to these characteristics, asbestos was used in many buildings and other structures throughout the 1900s. One estimation is that up to 80 percent of all buildings constructed before 1978 had asbestos within the design.

What is the risk? Asbestos was frequently used in older buildings and structures, often as insulation. It has the ability to linger in the air even after a fire has been extinguished. A victim of a fire and even anyone surrounding it is at risk of asbestos exposure. Over time asbestos exposure may lead to serious health problems including mesothelioma.
What is mesothelioma? Mesothelioma (mez-uh-thee-lee-O-muh) is a type of cancer that can be either malignant or benign. The malignant type of mesothelioma is the most hazardous form of cancer and may be deadly in most cases. This cancer affects the mesothelium, which protects the heart, stomach, lungs, and other organs by making a special fluid that allows the organs to move.

Asbestos exposure Asbestos becomes exposed as a result of the fire itself or as the structure of the building fails or deteriorates.

In the initial stages of extinguishing a fire the burning asbestos may become damaged to the point where the fibers are easily released into the air. Once exposed into the air, it is easy to breathe it, where it becomes lodged in tiny sacs lining organs, and the victim is not able to breath or cough them out. Most protective equipment that firefighters use will eliminate the exposure risk.

In the secondary stages of extinguishing a fire, some firefighters may get rid of the protective gear because it is uncomfortable. The danger here is that the remaining debris may still contain a high level of asbestos and may release it when overturned.

Less common is within the firehouses themselves. Many fire buildings are older whose infrastructure required a substance resistant to heat. Many of these older buildings have pipes and electrical fixtures that were insulated with asbestos compounds.

Measures to stay protected for fire professionals There are many measures that fire professionals can and do exercise in order to remain protected from asbestos exposure. These include:

  • » Keeping the Self Contained Breathing Apparatus (SCBA) on at all times. This piece of equipment was designed to protect the individual from gases, dust, and other toxic substances. This is also very heavy and hot and it may become tempting to take it off when the fire becomes out of control. However, asbestos levels still remain high so it is best to keep it on.
  • » Keep respirator cleaning supplies and replacement cartridges handy.
  • » Wear protective clothing.
  • » Shower and change your clothes before going home so the substances do not follow.
  • » Do not sweep or handle dry dust that may contain asbestos or other harmful materials.

Quit Smoking Another measure to stay protected is to quit smoking. Cigarette smoking alone may cause lung cancer and asbestos exposure alone may cause lung cancer. Smoking cigarettes could increase your risk of developing lung cancer after having an asbestos exposure. In this occupation it may be wise, especially since asbestos exposure is repeated and often close-up.
