Fire fighting foam is used to smuther fires. The foam will work as a blanket on the fire to prevent oxygen and flames from re-igniting the area. Foam is best used on oil or gas spills but my fire department uses it for anything on fire to get the job done right and fast. Fire fighting foam is used to smuther fires.

we have to distinguish between firefighting and fire alarm system. fire fighting is mechanical work (either sprinkler system or Foam or CO2 or FM200) and there is fire alarm or detection system this is an electrical thing that includes ( detectors an fire alarm system) for electrical control building we use FM200.
they both work together 4 movement and protection of the boby

A siemens fire system is more of a upscale fire system it is different than using heat of smoke to detect fire which can be a hassle it uses gases. It is very efficient and works well.
Foam nozzles work by mixing water and a foaming agent under high pressure to produce foam. The foaming agent creates bubbles in the water stream, which expands the volume of the foam. This foam is then used for firefighting or cleaning, as it is more effective at smothering fires or clinging to surfaces.
A Class A, B, C, or ABC fire extinguisher works wonders on several different types of fires. A is good for wood, paper, etc. B is good for liquids. C is good for electrical fires. Do not use a Class D, for these are best on metals (such as magnesium).
Football helmets typically use expanded polystyrene (EPS) foam as a primary material for impact absorption. This lightweight foam is effective at dissipating energy during collisions, reducing the risk of head injuries. Additionally, some helmets incorporate other foam materials, such as polyethylene or polyurethane, to enhance comfort and fit. These combinations work together to provide both protection and player safety on the field.
