This is foam injection as part of the actual firefighting?princessme said:subsurface foam injection
Subsurface foam injection is a method of applying fire-retardant foam to the interior of an above-ground covered tank, also known as an IFR tank. It involves injecting foam solution into the bottom of the tank, which then rises to the surface and spreads to cover the entire interior surface of the tank. This creates a layer of foam that acts as a barrier between the flammable liquid inside the tank and the external fire source, preventing the fire from spreading.
Subsurface foam injection can be used on any above-ground covered tank that holds a flammable liquid. This includes tanks used for storing gasoline, diesel, oil, and other fuels, as well as tanks used in the chemical and industrial industries. It is especially beneficial for tanks located in high-risk areas, such as near airports or in densely populated areas.
While subsurface foam injection is generally considered a safe and effective method for fire protection, it is important to follow proper safety protocols and guidelines. This includes ensuring that the foam solution is properly mixed and that the injection equipment is functioning correctly. It is also important to regularly inspect and maintain the tank and foam system to prevent any potential safety hazards.
Subsurface foam injection is considered one of the most effective methods for fire protection in above-ground covered tanks. It is often preferred over other methods such as fixed roof foam systems or floating roof foam systems because it provides better coverage and requires less maintenance. Additionally, subsurface foam injection can be used in tanks with a variety of different liquids, whereas other methods may only be suitable for certain types of liquids.
The main benefit of subsurface foam injection is its ability to quickly and effectively extinguish fires in above-ground covered tanks. This can help prevent catastrophic damage to the tank and surrounding areas, as well as reduce the risk of injury or loss of life. Subsurface foam injection also requires minimal maintenance and can be easily integrated into existing fire protection systems, making it a cost-effective option for tank owners.
