Automatic Nozzles: Another tool in the toolbox
Through the years, the most debated piece of equipment and the one that draws more passion from firefighters than anything else has been the nozzle. This article focuses on probably the most controversial nozzle-the automatic nozzle. It will cover what the automatic nozzle is designed to do and how it can be used.

UL Air Entrainment Testing
As part of the 2013 DHS Grant to study the “Impact of Fire Attack utilizing Interior and Exterior Streams on Firefighter Safety and Occupant Survival” testing was conducted at the Delaware County Emergency Services Training Center in Sharon Hill, PA to measure the amount of air being entrained into the structure by Fire Attack operations. Each test was designed to evaluate differences in entrainment, if any, by looking at different nozzle types, stream types, application patterns, as well as different compartment and ventilation configurations. These tests were conducted over a four day period where more than 150 tests were performed resulting in tens of thousands of data points as well as hours of video and hundreds of still images.
