The 50 KG BC Type Fire Extinguisher (Outside Gas Cartridge) is a high-capacity firefighting system designed for medium to large-scale fire hazards, especially those involving flammable liquids (Class B) and gases/electrical equipment (Class C).
It uses BC type dry chemical powder, typically based on sodium bicarbonate (SBC), which works by interrupting the chemical chain reaction of fire and forming a smothering layer over burning fuel. This makes it highly effective for petrol, diesel, oils, LPG, and electrical panels.
A key feature of this extinguisher is the external CO₂ gas cartridge, which is activated during operation to pressurize the cylinder. This ensures rapid and powerful discharge, making it ideal for emergency situations. Similar trolley-mounted DCP extinguishers are designed with CO₂ cartridge systems for reliable performance and durability.
The extinguisher is mounted on a robust trolley, allowing easy movement across industrial areas despite its weight. It includes a long hose (approx. 3–4 meters) and nozzle for safe-distance firefighting.
Typical performance features (approx.):
- Discharge Time: 30–40 seconds
- Range: 5–8 meters
- High fire rating for liquid fires
- Operating pressure: ~15 kgf/cm²
The cylinder is constructed from heavy-duty mild steel with corrosion-resistant coating, ensuring long service life in harsh industrial environments. These extinguishers are commonly used in fuel depots, petrochemical industries, airports, tank farms, and large factories.
