Building on Fire Containing Asbestos

Risks from Fires in Buildings Containing Asbestos

When a building containing asbestos catches fire, the danger escalates. Heat and damage can cause asbestos fibers to become airborne, creating significant health risks for anyone nearby. This airborne asbestos can also contaminate surrounding land and buildings, making fire incidents in asbestos-containing structures a serious public health concern.


The Dangers of Airborne Asbestos During a Fire

During a fire, asbestos mixed with other materials can break down and release hazardous fibers into the air. The smoke carries these fibers, which then settle on nearby homes, gardens, or other structures. This increases the risk of exposure for residents, workers, and emergency responders.

A tragic example is the collapse of the Twin Towers on September 11th, 2001. Dust clouds released during the disaster contained around 2,000 tonnes of asbestos fibers. According to experts, an estimated 410,000 people were exposed to the dangerous dust. While not caused by fire, this highlights the risks posed by airborne asbestos during catastrophic events.


Buildings Most at Risk

Buildings constructed before 1999, when asbestos was banned in the UK, are more likely to contain asbestos. These include residential, commercial, and industrial properties. Older buildings also often lack modern fireproofing standards, increasing their vulnerability during a blaze.

Health Risks from Fire-Related Asbestos Exposure

Inhaling asbestos fibres released during a fire can lead to several serious health issues:

  • Asbestosis: A chronic lung condition caused by long-term exposure to asbestos.
  • Lung Cancer: A deadly cancer often linked to asbestos and compounded by smoking.
  • Pleural Plaques: Thickened areas on the lung lining that indicate asbestos exposure.
  • Mesothelioma: A rare but aggressive cancer of the lung lining or abdomen.

Firefighters are also at high risk as they work to suppress fires and manage associated dangers.


Managing Fire Risks in Buildings with Asbestos

Conduct Fire Risk Assessments

Regular fire risk assessments are crucial for identifying hazards and implementing mitigation strategies. In the UK, non-domestic properties and communal areas of rented properties require these assessments by law.

Inform Fire Services

If an asbestos survey reveals the presence of asbestos in your building, inform your local fire brigade. This allows them to take extra precautions, such as bringing a decontamination unit to the site during a fire.

Keep Asbestos Survey Reports Updated

Asbestos survey reports help fire services assess sites and implement safety measures during emergencies. These reports should be reviewed regularly to ensure they remain accurate.


Frequently Asked Questions

Q: What health risks are associated with inhaling asbestos during a fire?
A: Exposure to asbestos fibers in smoke can lead to asbestosis, lung cancer, pleural plaques, and mesothelioma. These diseases are often severe and life-threatening.

Q: How can building owners manage fire risks in asbestos-containing buildings?
A: Conduct fire risk assessments, maintain fire safety equipment, and ensure fire services are informed about the presence of asbestos in the building.

Q: Are there guidelines for managing asbestos risks during fires?
A: Yes, UK regulations require fire risk assessments for non-domestic and communal properties. Informing fire services about asbestos ensures they can take necessary precautions.
