On December 22, 2018, Chicago experienced its second significant fire of the day at 6417 N Ravenswood Avenue. This incident followed an earlier fire earlier that same afternoon, making it the second 2-11 Alarm callout within hours.
The initial dispatch for this fire was to Engine 43, which was initially called to address what was reported as rubbish fire. However, upon further assessment, the fire was upgraded to a full structure fire. As I was already at another fire location on Clark Street, I quickly moved over to this site. When I arrived, the scene was dominated by thick, billowing smoke emanating from a single-story auto body shop. The firefighters were visibly overwhelmed as smoke poured out from every possible opening.
Upon entering the building through a forced door on the side B, the crew encountered intense smoke conditions. They tried to advance but were soon ordered to withdraw by the Incident Commander due to the severity of the blaze. At that point, the decision was made to transition to a more defensive strategy. The fire proved to be particularly tenacious, with minimal progress being made despite the efforts of multiple teams. Eventually, additional resources were brought in, including several box companies, but due to limited staging areas, a second alarm was called. Despite the challenges, the firefighters managed to contain the fire, preventing it from spreading to neighboring structures. Over 8 handlines and 2 aerial master streams were utilized during the peak of the firefighting operation.
The fire ultimately breached the roof, but thanks to the relentless efforts of the Chicago Fire Department, adjacent buildings were spared from extensive damage. Engine 43, along with other units like Engine 71 and Tower Ladder 21, played crucial roles in containing the blaze. Images from Chi-Town Fire Photos capture the intensity of the situation, showing firefighters fully engulfed in smoke, battling flames, and working tirelessly to extinguish the inferno.
This fire serves as a stark reminder of the dangers faced daily by our brave firefighters and the importance of having well-trained emergency responders ready to handle such emergencies.

Alloy Steel Pipe
Alloy pipe is a kind of seamless Steel Pipe, its performance is much higher than that of general seamless steel pipe, because this type of steel pipe contains more Cr, its high temperature resistance, low temperature resistance, corrosion resistance performance is much better than other Steel pipe, so the alloy pipe is widely used in petroleum, aerospace, chemical, electric power, boiler, military and other industries.
Alloy steel is steel that is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties. Alloy steels are broken down into two groups: low-alloy steels and high-alloy steels. The difference between the two is somewhat arbitrary: Smith and Hashemi define the difference at 4.0%, while Degarmo, et al., define it at 8.0%.Most commonly, the phrase "alloy steel" refers to low-alloy steels.
Strictly speaking, every steel is an alloy, but not all steels are called "alloy steels". The simplest steels are iron (Fe) alloyed with carbon (C) (about 0.1% to 1%, depending on type). However, the term "alloy steel" is the standard term referring to steels with other alloying elements added deliberately in addition to the carbon. Common alloyants include manganese (the most common one), nickel, chromium, molybdenum, vanadium, silicon, and boron. Less common alloyants include aluminum, cobalt, copper, cerium, niobium, titanium, tungsten, tin, zinc, lead and zirconium.
