Firefighters occasionally deal with fires in compartments where it is too dangerous to enter. There may be pressurized containers, flammable liquids or gases, acids, radioactive materials or other dangerous goods. In some cases, the safest practice is to simply let the building burn down and protect exposures. However, in other cases, that may not be an option; therefore, a safe way to handle the situation is required.
Fognails provide a solution to suppress a fire inside a compartment without immediately assigning firefighters inside. By cooling the smoke through the floor, walls or ceiling, Fognails can limit fire spread and conceivably prevent further heating of dangerous materials such as pressurized containers. The Fognails can be put in place and then remotely controlled to minimize the firefighters time and exposure to potentially dangerous locations. If the smoke is cooled and rendered incombustible, firefighters can then proceed to ventilate the compartment. The ventilation may increase visibility and provide an opportunity to better assess the situation inside. When the compartment is deemed safe, the firefighters can then enter for final extinguishment and overhaul.
