Fire Extinguisher For Hospital

A fire extinguisher is a portable, handheld device used to control or extinguish small fires by releasing a substance to cool the fire, remove oxygen, or interrupt the chemical reaction. It consists of a cylindrical pressure vessel containing an agent like water, foam, carbon dioxide, or dry powder, propelled by a handle-operated release valve. Different types are designed for specific fire classes (A, B, C, D), and using the wrong type can be dangerous. How it works Cools the fire: Some agents, like water, absorb heat as they turn to steam. Removes oxygen: Agents like foam or steam create a barrier between the fire and the surrounding air. Interrupts the chemical reaction: Dry chemical extinguishers disrupt the chemical process that sustains the fire. Key components and features Cylinder: A pressure vessel made of high-strength steel to contain the extinguishing agent. Agent: The substance that puts out the fire, such as water, foam, carbon dioxide, or dry powder. Discharge mechanism: A valve and nozzle that are activated by a handle and a release pin to spray the agent. Pressure gauge: Indicates if the extinguisher is properly charged and ready for use. Types of extinguishers and their uses Water: Effective on Class A fires (wood, paper, textiles). Foam: Suitable for Class A and B fires (flammable liquids like grease or gasoline). Carbon Dioxide (CO2cap C cap O sub 2𝐶𝑂2): Used for Class B and electrical fires (Class C) because they leave no residue. Dry Chemical: Versatile, with multipurpose versions effective on Class A, B, and C fires. Important safety considerations Fire extinguishers are for small, contained fires, not out-of-control blazes. Always ensure you have a clear escape route before attempting to use one. Using the correct type of extinguisher for the fire is crucial to avoid making the situation worse or causing injury
