explain the following types of fire extinguishers are used and state their colours. i. foam, ii. vaporizing liquid

i. Foam fire extinguishers: Foam fire extinguishers are designed to extinguish fires that involve flammable liquids, such as gasoline, oil, or grease. They work by smothering the fire and cutting off the oxygen supply, which helps to prevent the fire from spreading. Foam fire extinguishers are usually identified by a cream or yellow color.

ii. Vaporizing liquid fire extinguishers: Vaporizing liquid fire extinguishers, also known as clean agent fire extinguishers, are designed to extinguish fires that involve electrical equipment or combustible gases. They work by releasing a fine mist of a chemical agent that absorbs heat and disrupts the chemical reaction that is causing the fire. Vaporizing liquid fire extinguishers are usually identified by a blue color.
