Special Hazards can be declared as a room or a piece of equipment and generally occur in areas with a high concentration of technical equipment, such as data centers and testing facilities. Special hazards offer unique solutions for these areas if traditional fire alarms and sprinkler systems cannot adequately protect the designated area.
Special Hazard Systems are defined as but not limited to:
Special Hazard Fire Protection systems are:
Types of Special Hazard Fire Protection systems are:
Special Hazard Fire Protection systems include detection and control coupled with a fire suppression system. Some common fire suppression agents we use in these systems include:
Clean agents suppress fires using a waterless gaseous system. This type of system offers very effective extinguishing agents without any residual effects to the area protected. They are life-safe in design and will not disrupt normal business activities.
Inert gases extinguish fires using a compressed gas system by reducing the amount of oxygen in the area. This type of system is quite effective on all electrical equipment and difficult environments where gas systems are not ideal. They are electrically non-conductive and in most cases life-safe by design, without environmental issues. Specific systems are even effective on flammable metal fire like sodium and lithium.
CO2 Carbon Dioxide
Carbon dioxide suppresses fires using a gaseous system from local application to specific equipment, or in a total flooding system. This type of system offers an effective fire extinguisher without any residual effects to the area protected. They are not designed for occupied areas and will not disrupt normal business activities.
Water mist extinguishes fires using less than 1000 micron-sized droplets of water. This system offers effective protection with minimal mess, as compared to standard fire sprinklers. These systems are lower cost than gas systems and have no environmental impact and minimal water damage if a fire occurs.
Foam extinguishes fires by cooling and coating the fuel source. This type system is used for the protection of Class B (Flammable Liquids Polar Solvents and Hydrocarbon) fires. There are many types of foam used, including low expansion foam in fixed systems and high expansion in enclosed spaces like aircraft hangars. There are also foam systems that are effective on Class A fires by lowering the surface tension of water to better saturate the surface.
Dry chemicals extinguish fires with a chemical commonly found in portable fire extinguishers. These systems offer cost-effective protection for industrial paint spray, flammable dipping, and mixing and storage areas. These are also designed for fueling areas and off-road vehicle systems. Dry chemical systems are more affordable than sprinklers and are much more effective than water.
