Yes because foam is less dense than burning oil so it lies on top of the oil and cuts through the air supply.
Its any fire which involves a liquid substance that can cat light i.e petrol fires are liquid fires, as is over heated cooking oil. This would be fires where the use of water to fight them would prove more damgerous as the pressure of the injected water could and does splash the ignited fired liquid over other distances and this causes more fires to fight.It these styles of fire co2 gas and or foam is normally used - in a kitching cooking oil fire a fire blanket can be used to starve the fire of oxygen.
Just as you can blow out a burning match with your breath, explosives are used to "blow out" oil well fires. The fires are so violent ind intense that normal firefighting methods will not work.
I love to start my day with a cappuccino topped with frothy foam.
No - you wouldn't want to put out an oil fire out with water, it would spread. There are also checmicals that are used to deprive the fire of air. Powders (Like your household extinguisher) fires can also be smothered with blankets etc. Explosives are used to put out very large fires like oil well fires.
Foam cups are often used in experiments because they are inexpensive, disposable, and provide good insulation for maintaining constant temperatures. Beakers are typically made of glass and may not provide the same level of insulation as foam cups. Additionally, foam cups are lightweight and easy to handle, making them convenient for various experiments.
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).
No. I forbid it!
all countries use oil stoves, cars, fires.
Water, foam, powdered chemicals like sodium bicarbonate
Yes, you can use a foam roller for oil-based paint, but it’s essential to choose the right type of foam roller. A high-density foam roller is best suited for oil paints as it can hold more paint and provide a smoother finish. However, be aware that cleaning foam rollers after using oil-based paint can be challenging, and it’s often easier to use disposable rollers for this purpose.
Liquid (oil) fires.
Foam spray extinguishers are not recommended for fires involving electricity, but are safer than water if inadvertently sprayed onto live electrical apparatus.
foam is used for fire suppression. what it does is it cools the fire and to coats the fuel, preventing its contact with oxygen, and then the fire is out.
A 'dry powder' extinguisher. Water or foam extinguishers will destroy the circuits (and shouldn't be used on electrical fires).

A cream fire extinguisher typically contains a mixture of water and foam concentrate, which is designed to combat Class A (solid combustibles) and Class B (flammable liquids) fires. The foam helps to smother the flames by forming a barrier that cuts off the fire's oxygen supply while also cooling the burning materials. The extinguisher is pressurized with air or nitrogen to allow for effective dispersal of the foam when activated. It is important to use a cream extinguisher only on appropriate fire classes, as it is not suitable for electrical or cooking oil fires.
Class K extinguishers are used on Class K fires, i.e., kitchen grease. It may use a special high-temperature foam that causes saponification of the fat and oil, causing it to be extinguished.
