Combustible materials played a role in Tver high-rise fire spread

Initial findings from the Tver fire incident

According to an article from the National Fire Protection Association (NFPA), the fire that engulfed a high-rise building under construction in Tver, Russia, on 14 March, showcases the potential dangers of combustible façades.

The blaze, which rapidly consumed the structure, has prompted experts to consider the building’s exterior and its construction phase as key factors in the fire’s swift spread.

The NFPA’s perspective on combustible exterior wall assemblies

Following the tragedy of London’s Grenfell Tower, the fire and safety industry has been vocal about the risks associated with combustible exterior wall assemblies.

These façades, which have gained popularity for their modern appearance and energy efficiency, often include materials that can expedite fire propagation.

In light of the Tver incident, the NFPA joins other experts in drawing comparisons to previous fires exacerbated by similar materials.

Dr. Ankit Sharma of NIST, reflecting on the event, stated: “This is one of the craziest fire spreads I have ever seen.

“Using combustible façades is akin to wrapping your entire building in gasoline and waiting for disaster to happen.”

Construction sites identified as a fire risk by the NFPA

The NFPA highlights that buildings under construction are inherently at a higher risk for fires.

The absence of fire barriers, sprinkler systems, and the presence of combustible construction materials create a prime environment for fire outbreaks.

Speculation around the Tver blaze suggests that construction practices, such as the use of mesh netting for temporary enclosures, might have contributed to the rapid spread of the fire.

The NFPA’s standards, such as NFPA 241, address these risks by setting forth requirements for materials used in temporary enclosures to enhance fire safety on construction sites.

NFPA’s global concern over combustible materials

The Tver fire is part of a concerning trend of high-rise fires linked to combustible materials, a reality that the NFPA has been addressing through standards like NFPA 285.

However, as Robin Zevotek of the NFPA explains, enforcement of these standards poses challenges: “Codes, standards, and testing are vital components of the Fire & Life Safety Ecosystem™.

“However, without a unified authority for code enforcement and a commitment from building owners to prioritize safety, our efforts face significant hurdles.”

NFCC outlines safety considerations for new high-rise residential buildings

New safety measures proposed for high-rise residential buildings

The National Fire Chiefs Council (NFCC) has issued an opinion paper, highlighting crucial considerations for fire and rescue services in the design of new high-rise residential buildings.

This move follows the Government’s announcement in July 2023, mandating that all new residential buildings over 18 metres must include at least two staircases to ensure safer evacuation routes and firefighting operations.

Staircase independence and safe egress a priority

The NFCC’s paper stresses the importance of designing stairways that are independent of each other, ensuring that a single fire does not jeopardise multiple escape routes.

It emphasises the necessity of providing safe egress for all occupants, including those who may find it challenging to use stairs.

The Council also calls for designs to incorporate sufficient resilience and redundancy, particularly in access facilities for firefighters.

Gavin Tomlinson, Chair of the NFCC’s Protection Committee, reflected on the objectives of these recommendations: “We want to be sure these buildings are safe places to live and NFCC is committed to supporting fire and rescue services as they take on these new checks.

“We are expecting Government to issue new guidance shortly, but we have a clear view of what we think are the key priorities for fire and rescue colleagues when reviewing the design of new high-rise buildings.

“What we’re proposing is common sense, such as making sure that stairways are independent from one another so that a fire does not impact on multiple exit routes, making sure there are safe routes of escape for people with additional needs, and ensuring firefighters have the appropriate access and facilities.

“This is what we are advocating for in our discussions with partners in government.”

Transition period and consultation with fire services

The Government’s proposals will be formally integrated into statutory guidance following a 30-month transition period.

During this time, developers will have the option to adhere to either the new or existing guidelines.

The NFCC’s publication aims to offer clarity and uniformity in firefighting considerations for the design of escape routes in these buildings.

It also acknowledges that fire and rescue services are increasingly being consulted by building designers on how to implement multiple escape pathways effectively.

IFSJ Comment

The National Fire Chiefs Council’s initiative to outline key safety considerations for the design of new high-rise residential buildings marks a proactive approach to enhancing fire safety standards.

By advocating for independent stairways, inclusive escape routes, and adequate facilities for firefighters, the NFCC underscores the importance of a comprehensive safety strategy that protects all building occupants.

This initiative, aligned with forthcoming government guidance, represents a significant step towards preventing tragedies similar to past incidents.

As the construction industry adapts to these new requirements, the emphasis on collaboration between fire services, government, and developers is essential for creating safer living environments in high-rise buildings across the country.
