Fires in buildings are not just destructive due to flames and heat; they can also unleash hidden dangers such as asbestos, once a common building material known for its durability and fire resistance.
This article delves into the often-overlooked hazard that arises when asbestos-containing materials are compromised by fire. Asbestos, once deemed safe and used extensively in construction, can become a silent but deadly hazard when disturbed.
What Fire Can Do to Asbestos
When a fire engulfs a building containing asbestos, the high temperatures and structural collapse can compromise asbestos-containing materials. This damage often causes asbestos fibres to become airborne, creating a significant health hazard.
Asbestos, which may be present in insulation, floor tiles, roofing and other building materials, is relatively harmless when intact. However, once these fibres are disturbed by the fire and subsequently released into the air, they pose a critical risk.
Health Risks of Asbestos Exposure
Asbestos exposure is linked to a range of serious health issues, predominantly affecting the respiratory system. When asbestos fibres are inhaled, they can embed themselves deep within the lung tissue and the pleural lining, leading to chronic and often fatal diseases. These conditions do not manifest immediately but can develop over years or even decades.
Asbestosis
Asbestosis is a progressive, fibrotic disease of the lungs caused by the inhalation of asbestos fibres. Symptoms include shortness of breath, persistent dry cough, chest tightness and fatigue. The scarring of lung tissue impairs the ability to breathe and is irreversible.
Lung Cancer
Exposure to asbestos significantly increases the risk of lung cancer, particularly among smokers. This cancer forms in the lung tissue, usually in the cells lining the air passages. Symptoms are not always noticeable until the cancer has progressed and may include coughing, weight loss, chest pain and difficulty breathing.
Mesothelioma
Mesothelioma is a rare and aggressive cancer that primarily affects the lining of the lungs (pleura) but can also occur in the lining of the abdominal cavity or the heart. It is directly linked to asbestos exposure, with symptoms often not appearing until many years after exposure. These can include chest pain, abdominal pain, weight loss and fluid accumulation, which may not appear until the disease is in its advanced stages.
Lesser-Known Effects
In addition to the major diseases, asbestos exposure can also lead to pleural abnormalities such as pleural plaques, thickening and effusions. These conditions can cause discomfort and are indicators of significant exposure, potentially leading to more severe health issues over time.
What You Can Do: Mitigating Asbestos Exposure Post-Fire
In the aftermath of a fire, particularly in older buildings where asbestos-containing materials are present, it is crucial for employers, property managers and other responsible persons to take proactive steps to limit asbestos exposure. Here are several key strategies and responsibilities to consider:
1. Conduct a Thorough Risk Assessment
Before allowing anyone to re-enter the premises or begin cleanup, conduct a thorough risk assessment to identify areas and materials that may contain asbestos. This assessment should be performed by a certified asbestos professional.
2. Secure the Area
Restrict access to the affected area to prevent unauthorised entry and potential exposure. Set up clear signage and physical barriers to secure the site until professional cleanup has been completed.
3. Engage Professional Asbestos Removal Services
Employ licensed asbestos removal contractors to handle the cleanup and disposal of asbestos materials. These professionals have the necessary equipment and training to safely manage asbestos without causing further exposure.
What You Can Do: Preventing Post-Fire Asbestos Exposure
To effectively prevent asbestos exposure after a fire, especially in buildings constructed with asbestos-containing materials, specific preemptive and responsive actions are necessary. Employers, building managers and other responsible parties play a crucial role in initiating these measures:
1. Implement Asbestos Management Plans
For buildings known to contain asbestos, maintain an updated asbestos management plan that includes locations of asbestos, conditions of the material and procedures for dealing with asbestos disturbances. Ensure that this plan is readily accessible to all employees and contractors.
2. Training and Awareness
Regularly train employees about the dangers of asbestos and the safety procedures to follow if they suspect they are dealing with asbestos-containing materials. Responsible Persons of buildings should also receive fire stopping training to reduce the risk of fires.
3. Regular Monitoring and Inspections
Schedule regular inspections and air quality tests in areas known to contain asbestos to ensure that no asbestos fibres are present in the air. These checks should increase in frequency following any incident that might disturb asbestos.
4. Adhere to Health and Safety Regulations
Familiarise yourself with and adhere to local, national and industry-specific health and safety regulations regarding asbestos. Non-compliance not only risks health but can also lead to legal consequences.
5. Documentation and Record Keeping
Keep detailed records of asbestos presence, abatement, employee training and health monitoring. Documentation can be crucial for legal protection and compliance audits.
6. Open Communication Channels
Maintain open lines of communication with employees, tenants or any other stakeholders about the presence of asbestos and steps being taken to manage risks. Transparency can prevent panic and promote cooperative safety practices.
7. Provide Support for Health Monitoring
Offer medical surveillance programs for employees who have been potentially exposed to asbestos. Early detection of asbestos-related diseases can significantly affect outcomes.
Your Legal Responsibilities to Prevent Fire and Asbestos Hazards
In the UK, the legal responsibilities of a Responsible Person are clearly defined under various health and safety regulations. These regulations are designed to protect individuals from the risks associated with fire and asbestos in commercial, public and residential buildings. Understanding and fulfilling these responsibilities are crucial to ensure safety and compliance with the law.
Control of Asbestos Regulations 2012
The Control of Asbestos Regulations 2012 stipulates that the duty holder (often synonymous with the Responsible Person) must manage the risk from asbestos in non-domestic premises. This includes conducting a detailed asbestos survey where necessary and maintaining an up-to-date record of the location and condition of asbestos-containing materials (ACMs).
The duty holder is required to prepare and implement a robust asbestos management plan that outlines the measures and procedures to prevent exposure to asbestos fibres. This plan must be reviewed and updated regularly, particularly following any disturbances to ACMs.
It is crucial that all workers and contractors likely to come into contact with or disturb asbestos during their work have taken an asbestos training course and understand how to avoid risks.
Fire Safety Order 2005
The Regulatory Reform (Fire Safety) Order 2005 mandates that the Responsible Person must carry out a thorough fire risk assessment in all non-domestic premises, including common parts of multi-occupancy residential buildings. This includes identifying fire hazards, assessing the risk of fire and implementing appropriate fire safety measures.
It is also the duty of the Responsible Person to ensure that all fire safety equipment (like fire alarms, extinguishers and emergency lighting) is maintained in good working order and regularly checked.
Moreover, adequate procedures must be established to ensure that emergency routes and exits are suitable for all occupants and are kept clear at all times.
