Fire safety is essential in every household, yet conventional fire extinguishers can be expensive and often contain harmful chemicals. This study aims to develop a simple, cost-effective, and eco-friendly DIY fire extinguisher using safe, common household materials. The design involves a spray bottle connected via tubing to a small inner container holding vinegar and baking sod, with added dish soap. When activated, the vinegar and baking soda react to produce carbon dioxide gas, which helps to smother flames, while the dish soap forms foam that further cuts off the fire's oxygen supply. In testing, the extinguisher effectively suppressed small fires, with the foam enhancing the fire suppression duration and reducing the risk of re-ignition. The results confirm that this low-cost solution can function as a viable fire safety tool for minor household emergencies. The project concludes that environmentally friendly materials can replace chemical-based extinguishers in low-risk situations, offering a safer and more sustainable option. The broader implications include promoting environmental awareness, encouraging emergency preparedness, and supporting the development of green alternatives for public safety. This DIY extinguisher also holds potential for educational use, retail as eco-safety kits, and inclusion in awareness campaigns on sustainable living and home safety.
