On January 19th, 2007 Firefighters From Richmond, California Fire Department responded to a working fire at a commercial building. In the first video below you can see firefighters from the El Cerrito Fire Department using a one cut technique on a rolling steel door. This is just another way you can quickly gain access to a rolling door without wasting time. The other video shows the same technique in a controlled training environment. Feel free to comment on how your crews normally treat rolling steel doors like this.
