Some fires cannot be put out with water. If water is sprayed
onto an oil fire, the oil will float to the top of the water and
continue to burn. This can be very dangerous because water
can flow quickly, carrying the burning oil with it and
spreading the fire. Water should also not be used on fires
caused by electric appliances . The person spraying water
might receive an electric shock and be killed. A carbon dioxide extinguisher is the best thing to fight an electrical
fire. Pick out synonyms from the above passage- perilious,
persist

Answer:
Oil being lighter than water floats over it, so water cannot be used to extinguish oil fires. Moreover, as the water spreads it carries along the oil with which in turn extends the fire.
APWs are designed for Class A (wood, paper, cloth) fires only. Never use water to extinguish flammable liquid fires. Water is extremely ineffective at extinguishing this type of fire, and you may, in fact, spread the fire if you try to use water on it. Never use water to extinguish an electrical fire.
Water cools and smothers the fire at the same time. It cools it so much that it can't burn anymore, and it smothers it so that it can't make any more of the oxygen in the air explode. ... Water and oil do not mix, so throwing water on a grease fire only splatters the burning oil. Always use a lid to put out a stove fire.
