Why Historic Buildings are Highly Vulnerable to Fires During Renovations: Insights and Preventive Measures



A Recent Tragedy Highlights an Ongoing Risk


In a discouraging trend, the historic former stock exchange in Copenhagen, known as Børsen, has recently joined the list of heritage buildings like Notre-Dame Cathedral and Windsor Castle that have suffered severe damage due to fires during renovation. Just as it was preparing for its 400th anniversary, a fire broke out, devastating the building over several days. This incident underscores a critical challenge faced during the restoration of historic structures: managing the significant fire risks inherent in such projects (Milne, 2024).




Understanding the Fire Safety Challenges in Historic Buildings


What Makes Historic Buildings Susceptible to Fires?


Historic buildings like Børsen often combine several risk factors that make them particularly susceptible to fires, especially during renovations:


  • Old, Dry Timber: Many historic structures feature aged timber that is extremely flammable with his decreased moisture content.

  • Lack of Modern Fire Stops: Originally constructed without modern fire prevention designs, such as compartmentalization, these buildings allow fires to spread unchecked through hidden voids and across extensive areas.

  • Renovation Risks: The very nature of renovation work, which often involves welding, the use of open flames, and electrical equipment, introduces new hazards to these vulnerable environments.

Proactive Fire Safety Measures: How to Protect Our Heritage


Implementing stringent fire safety measures during renovations can drastically reduce the risk of fire in historic buildings. Here are essential strategies to consider:


  1. Comprehensive Fire Risk Assessments: Before beginning any restoration work, conduct thorough assessments to understand all potential fire risks associated with the building and the renovation activities planned. (Watts, 2008)

  2. Enhanced Fire Detection Systems: Install advanced fire detection systems tailored to the specific challenges of historic buildings, ensuring they can effectively monitor for the first signs of a fire.(Watts, 2008)

  3. Strict Hot Work Permits: Enforce a rigorous permit system for any hot work, including welding or use of open flames, and ensure constant monitoring during and after the work.(Watts, 2008)

  4. Emergency Response Plans: Develop and regularly update emergency response plans that include immediate firefighting measures and evacuation strategies tailored to the building's layout and renovation status. (Watts, 2008)

Frequently Asked Questions


Q: Why are historic buildings more at risk during renovations? A: The combination of older construction materials, the presence of extensive renovation equipment, and the lack of modern fire prevention designs significantly increases fire risks.


Q: What can be done to prevent fires in such buildings? A: Implementing strict fire safety protocols, using modern fire detection and suppression systems, and ensuring that all renovation work complies with stringent fire safety standards are critical steps.
