  » The Underlying Logic of Foam Fire Extinguishing   ★. Why can't water extinguish oil fires? • Density difference: Water is heavier than oil and sinks directly to the bottom, never touching the flame.   • Boiling over: The water at the bottom vaporizes instantly upon contact with high temperatures, expanding thousands of times in volume, splattering the o...

The foam fire truck is the core equipment for fighting flammable liquid fires. By precisely mixing foam concentrate with water at ratios of 1%, 3%, or 6% (accuracy ±0.5%), this foam fire truck delivers a uniform foam blanket for jet fuel fires at airports or tank fires at refineries. Its stainless steel foam tank and intelligent proportioning system ensure zero mixing errors, increasing fir...

A fire fighting water truck and an ordinary water truck may look similar. Both are large vehicles with water tanks, pumps, and hoses. However, their design, components, and intended purposes are fundamentally different. This article explains the key differences between fire fighting water trucks (also known as multi-purpose water trucks or forest fire trucks) and ordinary water trucks fr...

High-rise buildings present unique challenges for firefighting and rescue operations. Traditional ground-based equipment often lacks the reach needed to access upper floors from the outside. This is where aerial ladder fire trucks become indispensable. The YT25 aerial ladder fire truck, with a maximum working height of 25 meters and outreach of 15 meters, is specifically designed for such scenario...

Water pressure is the driving force behind every firefighting operation. Without adequate pressure, water cannot reach the fire, penetrate burning materials, or be effective. Fire fighting trucks must not only generate pressure but also maintain it consistently throughout the entire firefighting operation. This article explains how fire trucks produce, control, and sustain water pressure, covering...

A fire truck pump system is only as reliable as its components. From drawing water from a source to discharging it at high pressure, every accessory plays a critical role. This guide covers fire truck five key accessory categories: primers, ball valves, globe valves, foam proportioners, and hydraulic control systems. Understanding these components helps firefighters maintain their equipment a...

Fire trucks operate in harsh environments — humid climates, chemical spills, coastal salt spray. Without effective corrosion protection, metal components of a fire fighting vehicle rust, structures weaken, and firefighting capability drops. This article explains how rust forms, which tank materials resist corrosion best, and what coatings actually work. I. Three Common Types of Corrosion on ...

Foam fire trucks are essential for fighting flammable liquid fires at airports, oil refineries, chemical plants, and fuel storage facilities. Like all specialized equipment, foam fire trucks require regular maintenance to stay ready for emergencies. This article covers common faults and practical solutions. I. Types of Firefighting Foam Before discussing faults, understanding foam types is es...

A dry powder fire truck is a specialized firefighting vehicle designed to extinguish fires using dry chemical powder instead of water or foam. It is particularly effective for Class B (flammable liquids) and Class C (energized electrical equipment) fires, where water or foam may be ineffective or dangerous. Dry powder works by interrupting the chemical chain reaction of the fir...
