Installing Foam Fire Suppression Systems in Industrial Areas

Installing Foam Fire Suppression Systems in Industrial Areas: A Comprehensive Guide

As industries continue to grow and expand, fire safety has become a top priority for facility managers and owners. One effective solution to prevent or mitigate fires is through the installation of foam fire suppression systems. These systems are designed to extinguish Class B and Class C fires involving flammable liquids and gases, as well as electrical equipment.

Foam fire suppression systems work by releasing a thick, soapy-like substance that smothers the fuel source, preventing re-ignition. They are particularly effective in areas where water or dry chemical agents may not be suitable due to the risk of contamination or damage to sensitive equipment.

Before installing a foam fire suppression system, its essential to assess the facilitys fire hazards and identify potential risks. This includes evaluating the type and quantity of flammable liquids stored on site, as well as any electrical or gas-powered equipment present.

Here are some key factors to consider when selecting a foam fire suppression system:

  • Type of Foam: There are several types of foams available, each with its own characteristics and applications. These include:

  • Aqueous Film-Forming Foam (AFFF): A popular choice for suppressing Class B and Class C fires involving flammable liquids and gases.

    Film-Forming Fluoroprotein (FFFP) Foam: Effective against Class B fires, but may not be suitable for areas with high temperatures or humidity.

    Protein Foam: Suitable for extinguishing Class B fires in environments where water is scarce or where the risk of contamination is high.

  • Foam Concentrate: The foam concentrate is a critical component of the system, responsible for producing the foam when mixed with water. Its essential to select a concentrate that matches the specific type of foam being used.


  • Here are some key considerations when selecting a foam fire suppression system:

  • System Design and Configuration: The system should be designed to meet the specific needs of the facility, taking into account factors such as the size of the area, number of potential ignition sources, and available water supply.

  • Pipe Sizing and Layout: Proper pipe sizing and layout are crucial to ensure that the foam can reach all areas of the protected space in a timely manner.


  • In addition to selecting the right type of foam and system configuration, its also essential to consider other factors such as:

  • System Maintenance: Regular maintenance is critical to ensuring the system operates effectively. This includes checking for leaks, testing the system annually, and replacing the foam concentrate as needed.

  • Training and Testing: Facility personnel should receive training on how to operate and maintain the system, including testing procedures and emergency response protocols.


  • Heres an example of a potential installation scenario:

    1. Assessing Fire Hazards: Conduct a thorough risk assessment to identify potential fire hazards, including flammable liquids, electrical equipment, and gas-powered appliances.
    2. Selecting the Right System: Based on the results of the risk assessment, select a foam fire suppression system that meets the specific needs of the facility.
    3. System Design and Configuration: Work with a qualified engineer to design and configure the system, taking into account factors such as pipe sizing, layout, and available water supply.
    4. Installation and Testing: Install the system according to manufacturers instructions and test it annually to ensure it operates effectively.
