You are driving your vehicle, and a large fire starts burning under the hood. you have a portable fire extinguisher. you should stop your vehicle and

The first step towards putting that fire out would be to stop the car and use the fire extinguisher to put the fire out.

Further Explanation:

Having necessary fire safety measures is absolutely essential as we do not know when a fire might start due to a technical failure, worn out parts or simply due to overheating issues. During such cases, having a fire extinguisher becomes necessary as a preventive measure. The fire extinguisher, however, works for small fires and provides a temporary reprieve. Most fire extinguishers work on the principle of spraying jets of water at high pressure, or they mostly use dry ice or carbon dioxide to put out the fire. They can be easily bought on the market, and do not require an elaborate installation procedure. They can be found in various sizes, that depend on their volumes. You can use a small fire extinguisher that can be fitted in your car for use, in case of any fire hazards. However, fire extinguishers come in different types and are equipped to deal with different kinds of fires. Thus, you cannot use one fire extinguisher for all kinds of fires.

A fire extinguisher can be used only in case of an emergency small fire, but in case of a fire outbreak, it is always imperative to inform the fire brigade, for their expertise and skills could be utilized best in such life-threatening situations. Fire extinguishers are available for different types of fires, which are usually categorized from Type A fires which may originate from paper and wood to class F fires, involving fires from inflammable cooking oil and fat. Fire extinguishers are available in two types- the store pressured and the cartridge operated, out of which the former is more widely used. Small fire extinguishers use nitrogen or dry ice, while water and foam extinguishers typically require air to function. The best recommendation for a portable fire extinguisher is to use an ABC dry powder extinguisher, which can be used safely on fires from flammable liquids, combustible solids or even electrical wires. However, the residue is known to have a corrosive effect on metal, which is why it is essential to wipe away the residue after the fire is put out.

Explanation:

The term extinguisher means to stop or to repose. Fire extinguisher is tools which help in putting out the fire as they contain either water or ice or carbon dioxide gas in it.

There are colour codes set for different fire extinguisher, the colour tells what kinds of fires the fire extinguisher is useful for.

The four classes of fire extinguisher are A, B, C, and D.

•Class A puts out fires in normal combustibles such as paper and timber. It has a green triangle on it.

•Class B puts out fire caused by the inflammable liquids like gasoline, grease, and oil. It has a red square on it.

•Class C extinguishers are used only on fires caused by electrical equipment.  It has a blue circle on it.

the direction of the magnetic field produced by an electric current will change when the direction of the electric current changes. for example : if a current is flowing in a straight length of wire, the magnetic field is described by a concentric circle (using right-hand rule).
