Throughout history, fires and wildfires caused by climate worsening have caused significant damage to artefacts, buildings, and urban landscapes. Protecting cultural heritage requires a heightened focus on fire safety.
Current protection strategies are not always effective. Scientific literature emphasises the vulnerability of historical and cultural artefacts, buildings, and sites to fire damage. Fire poses several challenges to these resources, including structural integrity and functional requirements.
Structural Vulnerability
Many historic buildings and structures are constructed of materials that are clearly susceptible to fire, such as wood and straw. However, in reality, most such buildings have a high exposure to fire risk due to the interference of various factors, which lead to, for example, compromising the structural integrity of these buildings during a fire.
Non-combustible walls but susceptible to deformation, the presence of coverings and furnishings that do not react to fire performance, systems and rooms that prevent the compartmentalisation of rooms, are elements frequently found in historic buildings and residences that pose problems that cannot always be resolved with interventions on structures.
Architectural Design
The design features of historical structures may include intricate wooden detailing, ornate decorations, and other elements that can fuel the intensity of a fire. The design complexity can also make firefighting efforts challenging.
Compartmentation
Fire compartmentation is a construction technique that divides a building into smaller sections using fire-resistant materials. Its purpose is to slow down and contain the spread of fire and smoke by creating separate, fire-resistant areas within the building. Fire compartmentation functions as a passive form of fire protection, meaning it doesn’t require external intervention like fire alarms or fire extinguishers.
While many modern buildings incorporate fire compartmentation strategies to slow down and contain the spread of fire and smoke, many cultural heritage structures lack these features, making them more vulnerable to fires.
The primary reason for this is that it can be challenging to utilize appropriate fire-resistant materials in the right areas, such as large staircases in historic buildings that cannot be separated by fire-rated enclosures without compromising their intended aesthetic and functional purpose.
Ventilation Systems
In historic buildings, a significant obstacle to installing modern fire protection measures is the lack of adequate ventilation systems. This can severely impede the effectiveness of these measures, as inadequate or outdated ventilation systems can facilitate the rapid spread of smoke and flames during a fire.
Moreover, poor ventilation can hinder firefighting efforts and increase the risk of structural collapse, making it more challenging to contain fires and minimize damage
Roofing Materials
Traditional buildings often feature combustible roofing materials, such as thatched roofs, which are highly flammable and prone to ignition. Once ignited, these roofs can accelerate the spread of a fire and pose significant challenges for firefighters due to their design and location.
Accessibility for Firefighters
Limited access points, narrow staircases, and challenging layouts can impede the swift response of firefighters. Difficulties in reaching the source of the fire can result in delayed intervention.
Heritage Conservation Measures
Conservation efforts may introduce materials or treatments that inadvertently increase fire risk. For example, the use of certain chemicals or preservation techniques may make the structure more susceptible to combustion.
Moreover, renovation work can involve the use of open flames, sparks, and other ignition sources, which can easily ignite combustible materials in these buildings.
Lack of Fire Suppression Systems
Traditional buildings may be deficient in contemporary fire suppression systems, such as sprinklers, which are essential for controlling and extinguishing fires before causing significant damage. Nevertheless, the installation of sprinklers in historic buildings is not always feasible due to factors such as age, design, or location.
Building Age and Deterioration
Aging structures may experience degradation of materials, weakening the overall integrity of the building. Deterioration can make it easier for fires to spread and increase the risk of structural collapse.
Proximity to Other Structures
Close proximity to other buildings can facilitate the rapid spread of fire from one structure to another. This is particularly relevant in densely populated historical areas.
Limited Fire Protection Measures
Historical sites may lack modern fire protection measures, such as sprinkler systems, fire-resistant materials, and smoke detection systems. Implementing these measures without compromising the authenticity of the site can be challenging.
Accessibility for Fire Service
Some cultural heritage sites are located in remote areas, making it difficult for fire services to quickly respond to emergencies. Limited accessibility can hinder the timely intervention necessary to prevent or minimize fire damage.
Lack of Comprehensive Risk Assessment
Conducting thorough risk assessments for cultural heritage sites is often complex. Identifying potential fire hazards, understanding the specific vulnerabilities of each site, and developing tailored mitigation strategies based on cost benefit analysis require expertise and resources.
Integration of Technology
Integrating advanced technologies, such as fire-resistant materials, monitoring systems, and firefighting drones, into historical sites without compromising their authenticity is a challenge. Striking a balance between preservation and the use of modern technology is crucial. Incorporating modern technologies into historic buildings can be a daunting task, particularly when it comes to traditional crafts like thatching.
The image of a roof in one of the few reconstructed Inca buildings at Machu Picchu highlights the delicate balance between innovation and preservation, as any attempt to replace this ancient technology with non-combustible materials risks compromising the authenticity of the structure.
Climate Change Impact
Climate change can contribute to an increased risk of wildfires, especially in regions prone to extreme weather conditions. In addition, it can expose vulnerable historic buildings to a greater risk of fire.
Climate change leads to extreme summer temperatures and altered rainfall patterns, resulting in increased droughts. These changes, in turn, increase the risk of wildfires, which can damage historic buildings. Higher temperatures and a lack of humidity create conditions where fires can spread more quickly and easily.
Additionally, materials used in the construction of historic buildings, such as wood and stone, may be more vulnerable to fires. Therefore, climate change increases the risk of wildfires that can damage or destroy historic buildings.
Understanding and mitigating the impact of climate change on cultural heritage sites is essential for long-term preservation.
Public Awareness and Education
Raising awareness among the public, site managers, and local communities about fire risks and preventive measures is crucial. Proper training on emergency response and evacuation procedures can help minimize the potential damage caused by fires.
Egress systems and People with disabilities safety
Safe accessibility is a crucial aspect of preserving cultural heritage buildings, but it can be challenging to implement. The following are some of the main aspects to consider when ensuring safe accessibility in historic buildings:
- Many cultural heritage buildings lack adequate emergency evacuation plans, which can endanger visitors with disabilities in the event of an emergency. Furthermore, such plans are rarely exercised, including those involving tourists.
- Insufficient fire safety measures. Cultural heritage buildings may lack adequate fire safety measures such as smoke detectors, fire extinguishers and emergency lighting, which can endanger visitors with disabilities in the event of a fire.
- Limited access to escape routes. Many cultural heritage buildings have narrow doorways, steep stairs or other barriers that can impede the access of people with mobility impairments to escape routes in an emergency.
- Inadequate signage and communication. Visitors with visual or hearing impairments may struggle to appreciate the cultural significance of a building without adequate signage or communication such as audio descriptions.
- Limited availability of accessible escape routes. Many cultural heritage buildings do not have adequate escape routes that are wheelchair-accessible or have other accommodations for visitors with mobility impairments.
- Lack of disability training for staff. Many cultural heritage institutions do not have trained staff to assist visitors with disabilities, which can lead to a lack of knowledge and understanding of how to best accommodate visitors with disabilities in an emergency.
- Limited availability of accessible first aid supplies. Cultural heritage buildings may not have adequate first aid supplies such as wheelchair-accessible first aid kits or communication devices for people who are deaf or hard of hearing.
- Inadequate lighting and contrast. Poor lighting and a lack of contrast between the building’s structure and its surroundings can make it difficult for visitors with visual impairments to navigate and appreciate the cultural heritage building.
- Limited availability of accessible storage areas. Cultural heritage buildings may not have adequate storage areas for visitors with mobility impairments or other disabilities, which can limit their ability to access exhibits or displays.
- Lack of disaster preparedness planning. Many cultural heritage institutions do not have adequate disaster preparedness or damage limitation teams.
Conclusions
Historic buildings are particularly vulnerable to fires due to several factors including combustible building materials intricate architectural designs inadequate ventilation systems flammable roofing materials the ageing and deterioration of structures and their proximity to other buildings.
Consequently implementing contemporary fire safety measures in historic buildings can be complex as it requires a careful balance between preserving the site’s authenticity and ensuring fire safety.
In the face of these risks which are exacerbated in several regions by the deliberate destruction of historical and cultural heritage as a weapon against communities or state entities and considering the new risks posed by climate change (which is increasing the risk of wildfires and presenting a growing threat to cultural heritage sites) specific actions can be initiated.actions can be initiated:
- public awareness and education about fire risks are crucial for the protection of cultural heritage.
- accessibility for people with disabilities is a major challenge in historic buildings, and the lack of adequate emergency evacuation plans, insufficient fire safety measures and limited escape routes can put visitors with disabilities at risk.
- correct assessment of fire risks and the choice of the most appropriate measures to ensure the conservation of historic buildings are essential.
