Protecting Your Investment: The Importance of Temporary Fire Suppression Systems During Building Construction

Fires can happen at anytime and whilst few and far between, they do start on construction sites during the construction phase prior to handover.

According to the Home Office, there were 375 fires in buildings under construction and 300 fires in buildings undergoing major renovation in England alone during the 2019/2020 period.

The primary causes of construction site fires in the UK include:

The average cost of a fire on a construction site is estimated to be around £1.7 million, taking into account property damage, project delays, and additional expenses.

A large proportion of construction site fires occur outside of regular working hours, typically between 6 p.m. and 6 a.m., highlighting the importance of temporary 24/7 fire detection and suppression systems and the importance of fire training for site security staff.

Fires on construction sites can lead to significant project delays, with some estimates suggesting that major fires can delay project completion by several months.

Insurance premiums for construction projects can be significantly higher if adequate fire safety measures, including temporary fire suppression systems, are not in place.

The UK has stringent safety regulations for construction sites, including the Construction (Design and Management) Regulations 2015 (CDM 2015), which mandate risk assessments and fire safety measures during construction.

These statistics underscore the significant risk of fires on construction sites in the UK and the potential benefits of implementing temporary fire suppression systems to mitigate these risks.

There are numerous benefits of installing temporary fire suppression systems during building construction or renovation, these include:

The Importance of Fire Protection During Construction

Fires on construction sites can be devastating. They not only pose a severe risk to life but also lead to significant financial losses, project delays, and long-term reputational damage. Several factors contribute to the heightened fire risk during the construction phase:

Exposed Combustible Materials: During construction, building materials like wood, insulation, and plastic are often left exposed, creating an environment where a fire can easily ignite and spread rapidly. Incomplete Fire Safety Features: A building under construction lacks the complete fire protection systems that would typically be in place in a finished structure. Without these systems, a fire can go undetected and unchallenged until it's too late. Hot Work: Construction activities often involve "hot work," such as welding, cutting, and grinding, which are common sources of ignition. Sparks from these activities can easily ignite nearby combustible materials. Temporary Electrical Systems: Construction sites rely on temporary electrical systems, which can be prone to faults and short circuits, further increasing the fire risk. Limited Access and Egress: The layout of a construction site is constantly changing, and access routes may be obstructed or incomplete, making it difficult to respond to a fire quickly and evacuate personnel safely.

Given these factors, it's clear that comprehensive fire protection must be considered a priority from the very beginning of the construction process. Temporary fire suppression systems offer a highly effective solution to mitigate these risks.

Understanding Temporary Fire Suppression Systems

Temporary fire suppression systems are designed to provide robust fire protection during the construction phase. These systems are adaptable, allowing them to be reconfigured and expanded as the building progresses. One of the most effective and versatile options for temporary fire protection is a temporary water mist system.

What is a Water Mist System?

A water mist system uses fine water droplets to suppress fire. Unlike traditional sprinklers that release large volumes of water, water mist systems create a mist of tiny droplets that quickly absorb heat and reduce oxygen around the fire, effectively suppressing it. The system is easier to install and requires less water, making it ideal for temporary applications.

Key Benefits of Water Mist Systems

  1. Efficient Fire Suppression: The fine mist produced by the system can rapidly cool flames and the surrounding area, effectively controlling or extinguishing the fire before it can spread.
  2. Reduced Water Damage: Since the system uses a lower volume of water compared to traditional sprinklers, there is significantly less water damage to the building materials, reducing cleanup and repair costs.
  3. Adaptability: The system can be easily adapted and expanded to cover different areas of the site as construction progresses. This flexibility ensures that fire protection is always in place, regardless of the project's stage.
  4. Quick Installation and Removal: Temporary fire suppression systems are designed for easy installation and removal, making them perfect for the dynamic environment of a construction site. They can be set up quickly and reconfigured as needed without disrupting the construction process.
  5. Cost-Effectiveness: Protecting a construction site with a temporary system is far more cost-effective than dealing with the aftermath of a fire. The system’s adaptability and reusability also add to its economic appeal.

Why Every Construction Project Needs a Temporary Fire Suppression System

The implementation of a temporary fire suppression system is not just a precaution—it is a vital component of risk management on any construction site. Here’s why every construction project should include one:

1. Protection of Life and Property

The primary goal of any fire suppression system is to protect lives. Construction sites are bustling environments with a high turnover of workers, contractors, and inspectors. In the event of a fire, a well-placed temporary fire suppression system can mean the difference between a minor incident and a catastrophic loss of life. By containing or extinguishing fires quickly, these systems also prevent significant damage to the property, preserving the investments made by stakeholders.

2. Compliance with Safety Regulations

In many regions, regulations mandate the implementation of fire safety measures on construction sites. Temporary fire suppression systems can help ensure that a construction site complies with these regulations, avoiding costly fines and legal complications. More importantly, adhering to these standards demonstrates a commitment to safety, which is crucial for maintaining a good reputation in the industry.

3. Mitigation of Financial Risks

The financial impact of a fire on a construction site can be enormous. Beyond the immediate costs of damage and rebuilding, fires can lead to project delays, increased insurance premiums, and potential lawsuits. By investing in a temporary fire suppression system, construction companies can significantly reduce these risks. The cost of installing a temporary system is negligible compared to the potential financial losses from an uncontrolled fire.

4. Adaptability to Changing Risks

Construction sites are dynamic environments where fire risks can change daily. As the building takes shape, different areas will require different levels of protection. For instance, the installation of electrical systems or the use of flammable materials in certain phases of construction can introduce new risks. A temporary fire suppression system, especially a low-pressure water mist system, can be adapted to address these evolving risks. The system can be repositioned, expanded, or scaled down as needed, ensuring that all areas of the site are adequately protected at all times.

5. Protection of Building Integrity

Beyond the immediate threat to life and property, fires during construction can compromise the structural integrity of a building. Even if a fire is contained, the heat and smoke can weaken materials, leading to long-term issues that may not be immediately apparent. By preventing fires or minimizing their impact, temporary fire suppression systems help preserve the quality and safety of the building in the long term.

Real-World Examples: The Consequences of Inadequate Fire Protection

There are numerous examples of construction projects that have suffered significant losses due to inadequate fire protection. Understanding these examples underscores the importance of implementing a robust temporary fire suppression system.

Case Study 1: The Glasgow School of Art Fire

The Glasgow School of Art, designed by the famous architect Charles Rennie Mackintosh, is a tragic example of the consequences of insufficient fire protection during renovation. In 2014, the building suffered a major fire that caused extensive damage. Four years later, while still under renovation, the building was engulfed by a second, even more devastating fire. This disaster highlighted the critical need for robust temporary fire suppression systems during construction or renovation of historic buildings. The lack of adequate protection during the renovation process led to the near-total destruction of one of Scotland’s most important cultural landmarks.

Case Study 2: The Notre-Dame Cathedral Fire

The Notre-Dame Cathedral fire in 2019 serves as another stark reminder. Though the fire occurred in a nearly completed renovation, the absence of an active fire suppression system during the construction work allowed the fire to spread rapidly, causing extensive damage. While the cathedral is now being restored, the incident emphasized the necessity of having temporary fire protection systems in place during any phase of construction, particularly in historic and valuable structures.

Choosing the Right Temporary Fire Suppression System

Selecting the appropriate fire suppression system for a construction site requires careful consideration of several factors:

1. Type of Construction Project

The nature of the construction project plays a significant role in determining the type of fire suppression system required. For example, a high-rise building under construction might require a more extensive and adaptable system compared to a smaller, single-story project.

2. Site-Specific Risks

Every construction site has its unique set of risks. A thorough risk assessment should be conducted to identify areas where fires are most likely to occur. This assessment will guide the placement and configuration of the temporary fire suppression system.

3. Regulatory Requirements

Local building codes and fire safety regulations must be considered when selecting a fire suppression system. These regulations may dictate specific requirements for fire protection on construction sites, such as the use of certain types of systems or the need for regular inspections.

4. Budget and Timeline

While cost is always a consideration, it should not be the only factor driving the decision. Investing in a reliable and effective temporary fire suppression system will save money in the long run by preventing costly fires and associated delays. Additionally, the timeline of the project should be factored into the decision, as the chosen system must be able to be installed and operational within the required timeframe.

5. System Flexibility

Given the dynamic nature of construction sites, the flexibility of the fire suppression system is crucial. The system should be easily reconfigurable to adapt to the changing layout and fire risks as construction progresses.

The Future of Temporary Fire Suppression Systems
