Normally fires, and hence fire extinguishers, are divided into different categories. While foam is not necessarily the best extinguisher for all types of fires, it has a great advantage as it can be safely used with most types. For example you don't want to use water on a electrical fire as water might short-circuit the device and start another fire. Similarly, using water for combustible fluid (petrol, etc.) is also not a good idea as most of such materials are lighter than water and will rise over and continue to burn. Since it is not always possible to determine the cause of the fire at first glance, many fire extinguishers are usually contain dry powder or foam, which be used for almost any type of fire.
For a fire fuel, oxygen and heat are needed forming the fire triangle, removal of any of these will result in the removal of the fire. The fire blanket will cover the fire and prevent oxygen from getting to it so that the fire cannot burn. What little oxygen is trapped under the fire blanket will quickly turn to carbon dioxide as the fire burns out.
Foam spreads easily and can form an effective barrier between the burning object and oxygen. Combustion needs oxygen to continue, so when foam blocks it, the fire dies out.
Fire requires 3 factors to exist: Oxygen Fuel Heat If you add the foam, it take up the area around the fire, displacing the oxygen, thus causing the fire to go out.
By cutting off the availability of free oxygen, needed for fire.
The foam cuts off the oxygen supply to the fire.
BIG ones
Use a dry powder extinguisher or foam (guess)
with foam
No,it does not need sugar to foam just water and yeast to make it foam u want it to foam alot put sugar.
The Oxygen that fuels a fire, is not able to get in, and the fire is put out. Just like with a candle snuffer. You put the snuffer over the flame, and the fire gets put out.
take away the air oxyagan
put foam over the foam
Not normal foam but carbon dioxide foam from a fire extinguisher. This special foam covers the fire and takes all the oxygen out of it, and with no oxygen, no fire!!!
The foam cuts the connection of fire with air (oxygen) & thus puts out fire.
Water and foam
smother it or use a foam fire extinguisher
Well, you CAN- depending on the type of fire.
foam fire extinguisher or a fire retardant spray
It tells you the elements of a fire, therefore it will help the easiest way to put out a fire. The 3 elements are: Oxygen, Heat and fuel. An example: A chip pan fire using oil. Foam extinguisher, as the foam sits on top of the oil, cutting off the oxygen.
A foam extinguisher.
Use a dry powder extinguisher or foam (guess)
water, helium and water vapor.
The gas extinguisher that is filled with carbon dioxide and one that is filled with foam can help put out a fire.
