Hello, I'm an expert in fire science and safety. Let's address your question about the effects of adding water to a fire.
Adding water to a fire can have different outcomes depending on the type of fire and the amount of water used. Here's a breakdown:
1. Ordinary Combustibles: For fires involving ordinary combustibles like wood, paper, or cloth, water is generally effective in extinguishing the fire. It works by cooling the material below its ignition temperature and by wetting the material to prevent re-ignition.
2. Grease or Fat Fires: Water should never be used on grease fires. Water can cause the fire to spread rapidly because it sinks and vaporizes, turning into steam and causing the hot oil to splatter and increase the fire's size.
3. Electrical Fires: Water should not be used on electrical fires because it conducts electricity, which can lead to electrocution or further spreading of the fire.
4. Chemical Fires: Some chemical fires react with water and can become more intense or even explosive. It's crucial to know the specific chemical involved before deciding on the appropriate extinguishing agent.
5. Metal Fires: Water is not effective on metal fires, such as those involving sodium or potassium, because it can react violently with the metal, producing hydrogen gas and potentially causing an explosion.
In summary, while water can be effective for some types of fires, it can indeed make other types worse. The key is to understand the nature of the fire and to use the appropriate fire extinguishing technique.

Not only could water destroy your electrical equipment making it unusable, but the water could also conduct electric shocks harming the people trying to put out the fire. In addition, did you know that adding water to a Class D fire fueled by combustible metals can actually make the fire worse?
