Still & Box Alarm in Chicago, 2-11-17 (part 3)

Posted on

This message just came in from Steve Redick: --- At around 2600 W 35th Street, there were reports of heavy smoke filling a large, fire-resistant warehouse. Upon further investigation, it turned out to be a vehicle fire located deep inside the building. Firefighters quickly responded and deployed MVU 923, which helped to pressurize the structure and effectively clear out the lingering smoke. It was quite impressive to see how well it worked. I managed to capture some great shots of the firefighting equipment too. Attached are a few photos that really show the intensity of the situation. The first one shows thick smoke billowing out of the warehouse, giving you a sense of just how serious it was. There’s also a shot of Chicago FD Truck 52 on the scene, looking ready to tackle anything. You’ll notice MVU 923 in action in another image, working hard to manage the situation. Additionally, there’s a close-up of firefighter tools, highlighting their preparedness for any emergency. For those interested, here's a short video clip showing MVU 923 in operation. Watching it in action is quite fascinating—it really demonstrates the efficiency of modern firefighting technology. --- I hope this gives everyone a better understanding of what happened today. Let me know if you need any more details or additional photos! --- *Note: All images are courtesy of Steve Redick.*

Welding Electrode

WELDING ELECTRODE:


The welding rod is composed of two parts: the welding core and the coating. The welding rod is to apply the coating (drug skin) evenly and centripetally on the welding core outside the metal welding core. Different types of welding rods have different welding cores. The welding core is the metal core of the welding rod. In order to ensure the quality and performance of the weld, there are strict regulations on the content of each metal element in the welding core, especially for the content of harmful impurities (such as sulfur, phosphorus, etc.). Limits, superior to base metal.
