Product Information
- Name : Fire extinguisher
- SKU : BLT-43
- Category : extinguishers
A fire extinguisher is the most basic portable and fixed fire-fighting equipment. Its cylinder is typically a red pressure-resistant steel bottle, filled with extinguishing agent and propellant gas. Compact in size and easy to access, it comes in two main types: portable and cart-mounted. Common types include dry powder extinguishers, carbon dioxide extinguishers, water-based extinguishers, and foam extinguishers. They can quickly extinguish a fire in its early stages and are widely used for initial fire emergency response in homes, shops, office buildings, factories, vehicles, and other settings. They are essential basic protective equipment for fire safety.

**Working Principle**
The cylinder stores pressurized propellant gas and extinguishing agent. After removing the safety pin and pressing the handle, the valve opens, and the internal pressure forces the extinguishing agent out at high speed: dry powder suppresses combustion by isolating oxygen and inhibiting chemical reactions; carbon dioxide extinguishes fires through low-temperature cooling and displacing air to suffocate the flames; water-based and foam extinguishing agents cover the burning surface to isolate air while cooling it down, thereby rapidly stopping the combustion reaction.
**Application Areas**
1. Civilian scenarios: initial fire suppression in homes, private cars, corridors, and shops.
2. Public buildings: standard fire protection equipment in crowded places such as office buildings, schools, hospitals, shopping malls, and hotels.
3. Industrial plants: targeted fire prevention and extinguishing in workshops, warehouses, distribution rooms, computer rooms, gas stations, and chemical storage areas.
