what is the best fire extiguishing agent for fighting glass fiber fire?

Question

we saw a fire in a factory making baots ,the fire fighter used foam insted of water ,the argument why they are not useing only water since its solid fire ,

Answer 1

When you think of a fire there are three main components that are needed for combustion to occur - Fuel, Oxygen, Heat - with a fourth being a chemical reaction.
When a firefighter is extinguishing a fire they are atttempting to break this chain. Without one of the three components above a fire won't continue to burn. So to break the chain you either need to cool, smother or remove the fuel source.
In a situation like the one you have presented removing the fuel isn't an option. Cooling the fire is, also smothering the fire is. Using foam is the most effective and efficient use of resources in this situation. Using water alone when there are other chemicals and fuel loads available is less effective.

Answer 2

In a factory making boats, it is not just the fibre glass hulls , but also the chemicals used to make the fibre glass hulls. These are commonly epoxy chemicals which behave a lot like oil in a fire (that is, a water stream can spread the fire). Even in the case of the fibre glass hulls, the hulls will melt and the molten mass will continue to burn -- a stream of water can cause the molten mass to spread and start other hulls on fire.

Foam is generally used in chemical fires because it smothers the fire and does not allow reignition even though the chemicals are still hot enough to burn.

Answer 3

the foam is better because water can spread the fire. water is only used on paper fires. the rest use either CO2 foam or particles, or different chemicals all together.

Answer 4

I'm not a fire fighting expert, but my physics and chemistry tells me that water should work fine.
