Saturday afternoon in Chicago brought another challenging fire incident, marking the second significant blaze in the city within a span of just two alarms. This particular fire erupted at 6417 N Ravenswood Avenue, a location that quickly became the focal point for emergency responders. According to reports from Eric Haak, the fire originated in a single-story commercial building, primarily affecting a rear section measuring approximately 75 feet by 75 feet. The roof of this area, constructed using trusses, proved particularly vulnerable, ultimately succumbing to the intense flames.
As the situation escalated, the fire spread rapidly, eventually breaching the roof. In response, firefighters deployed Tower Ladder 23 and the newly operational Tower Ladder 21 to gain control over the inferno. Their efforts were crucial in containing the damage and preventing further spread of the blaze.
Attached are several images capturing different aspects of the firefighting operation. The first photograph, taken by Eric Haak, showcases Engine 56 as it stands ready to assist in the effort. Another image highlights Deputy Fire Commissioner Tim Sampey, providing an essential perspective on the command structure during such emergencies. Further photos document the intense flames consuming the warehouse's truss-designed roof, the relentless work of firefighters battling the blaze, and the strategic positioning of Tower Ladder 23. Additional shots capture firefighters maneuvering a 2 1/2-inch hose line and the presence of Tower Ladder 21, which played a vital role in managing the fire from above.
The resilience and dedication of the Chicago Fire Department were evident throughout the ordeal, as they worked tirelessly to mitigate the impact of this devastating fire. These visuals not only depict the scale of the challenge but also honor the commitment of those who risk their lives to protect others.
Carbon Steel Plate
A carbon Steel Plate has usually been considered as the steel that does not contain much alloy steel elements, also named as mild steel. Generally, elements are C, Mn, P, S, Si, besides these, there are no minimum limits for elements of Al, Cr, Ni, Mo, V, etc.
Carbon steel plates are available in different grades depending on the carbon content and strength.
As the content of Carbon increase, the steel plate hardness increases.
Low carbon steel plate: For carbon content 0.06% to 0.25%, also we call it Mild Steel Plate.
Medium carbon steel plate: C content from 0.25% to 0.55%.
High carbon steel plate: 0.55% to 1.0%, also called hard steel plate.
Low carbon steel is the most common form, and it's very malleable and ductile. Medium carbon steel balances ductility as well as strength for excellent wear resistance. High carbon steel is exceptionally strong, while ultra-high carbon steel can be tempered to even greater hardness but no malleability.
As the percentage of carbon gets larger, steel can become harder and stronger through heat-treating. Carbon steel is usually heated to change the mechanical properties of steel, usually ductility, hardness, strength, and resistance of impact. Increasing the carbon content of carbon steel makes it harder and stronger, but reduces the steel`s ability to be welded, making it more brittle.
Carbon steel plate is most often used for structural purposes such as buildings, yet it has the flexibility to be worked into ornate designs. Low carbon steel sheet (wrought iron) is typically used for fences, chain links, gates, and railings. Structural steel (medium carbon steel) is used in cars, refrigerators, washing machines, buildings, and bridges. The steel sheets are normally made up of medium carbon steel.
