Fire disasters have become common in the 21st century due to several reasons and extensive industrialization and urbanization have added to this plight. According to the Times of India (daily) dated 22nd of December 2019, there were 27,027 fire-related deaths in India in the year 2017 and, every fifth fire-related death in the world took place in India during that year. These numbers have increased considerably in the preceding years and is a matter of concern. Firefighters face high-risk while dealing with fire in human settlements especially because of the difficulty in finding out the major spot of fire, accessing the areas affected and also due to the presence of trapped-individuals. Human presence in buildings with fire slows down firefighting considerably. The use of an Unmanned Aerial Vehicle (UAV) equipped with a thermal-camera can help identify the location of the fire and trapped individuals, and this could also be highly helpful in the case of fire in thickly populated colonies or high-rise buildings. To lower the direct involvement of firefighters with fire, through this paper, a specially designed attachment, coated with fireproof material that can hold and deploy fire-extinguisher balls, and which can be attached to existing UAVs is proposed. The attachment is made of Aluminum alloy 5052H-32 and it can hold four fire-extinguisher balls at a time which contain ABC dry powder each of 400 g and can extinguish 20,000 sq. cm. of fire in one use. The attachment can be operated using a remote control, thus avoiding direct contact of firefighters with fire and can be used to fight A, B and C class fire. The design of attachment proposed in this paper can be attached to any quadcopter with minimal modifications.
