... some photos from the Fox Lake fire that took place on April 8th, 2013, in the 38000 block of Hillandale, located in unincorporated Spring Grove. Engine 223 was the first on scene and found a two-story house fully involved in flames. Due to the severity of the fire, command called for additional resources, including an engine from Antioch and a tender from Spring Grove. A second alarm was then dispatched, bringing in more tenders and chief officers, as well as specialized squads from McHenry and Newport.
The terrain around the home was steep and difficult to navigate, making access challenging for both firefighters and equipment. Tenders had to backtrack several blocks along narrow, winding gravel roads to reach the scene. At first, there was concern that a resident might still be inside the burning house, but that turned out to be false—when the homeowner returned from the store, he found firefighters already working to save his home.
Firefighters worked late into the night, battling the flames and conducting a thorough overhaul of the remains. Fortunately, no injuries were reported. These images capture the intensity of the fire and the effort required by the responding crews.

### 1. **Classification by Filler Metal Composition:**
- **Pure Iron-Based Brazing Alloys:**
These alloys consist primarily of iron, with small amounts of other elements added for specific properties such as improved flow, wetting, or corrosion resistance.
- **Iron-Nickel (Fe-Ni) Alloys:**
These alloys contain significant amounts of nickel, which enhances the alloy's strength, ductility, and resistance to corrosion. They are often used in high-temperature applications.
- **Iron-Chromium (Fe-Cr) Alloys:**
Chromium is added to improve the oxidation resistance and hardness of the brazed joint. These alloys are suitable for applications requiring high wear resistance.
- **Iron-Manganese (Fe-Mn) Alloys:**
Manganese is added to increase the strength and toughness of the brazed joint. These alloys are often used in structural applications.
- **Iron-Silicon (Fe-Si) Alloys:**
Silicon is added to improve the fluidity and wetting of the filler metal. These alloys are commonly used in electrical and electronic applications due to their good electrical conductivity.
### 2. **Classification by Brazing Temperature:**
- **Low-Temperature Iron Base Brazing:**
This involves brazing at temperatures below 900°C (1652°F). It is suitable for joining materials that have lower melting points or are sensitive to high temperatures.
- **High-Temperature Iron Base Brazing:**
This involves brazing at temperatures above 900°C (1652°F). It is used for joining materials that can withstand higher temperatures and require stronger joints.
Iron base brazing is a category of brazing processes that use filler metals with iron as the primary element. This type of brazing is widely used in various industrial applications, particularly where high strength and good corrosion resistance are required. Below is a classification and brief introduction to iron base brazing:
