Study Notes
Fire Extinguishing Methods
- Several methods exist for extinguishing fires
- Water is effective for fires involving solids or liquids (e.g., wood, gasoline)
- Carbon dioxide is a colorless, odorless gas that reduces the oxygen available to the fire, thereby extinguishing it
- Dry chemicals, such as baking soda or powdered chalk, can smother flames and break the chemical reaction, thus extinguishing the fire
