Demonstration Burns
Oklahoma, March 2024
In March 2024, HEN Nozzles partnered with Quapaw Fire Department in Quapaw, Oklahoma, to conduct five live-fire demonstration burns using modern fuel packages designed to replicate contemporary fire behavior. The evolutions evaluated nozzle performance across garage, three-room, multi-room, and hallway fire scenarios. Using the BLADE™ pattern at 160 and 265 GPM, crews demonstrated wide-area coverage, effective surface cooling, and suppression across interconnected rooms and post-flashover conditions. These burns highlighted the BLADE pattern’s versatility and water application capabilities across varying fireground conditions.
Structure Fire Demonstration
No Vent Fire Room Hallway Push with VES Implications
In this burn, post-flashover conditions in the hallway and bedroom prompted suppression with a 160 GPM wide-blade stream, covering the hallway's width and effectively cooling surfaces for safer corridor access and superior fire coverage. Bedroom #2 had no vent in front of the flow and moved to a wide-blade attack, while “simulated” VES members in Bedroom #3 opened their door in front of the push, with a window open behind them.
Floorplan
Note: In the footage between 2:40 to 2:54 clearly demonstrating searching around the Bladed pattern in this dead-end vent profile, is not only safe, but extremely effective in providing good searchable protected environments with better cooling, coating, net gas contraction, good level of positive air entrainment, creating excellent lift and dominate suppression.
Structure Fire Demonstration
Garage Fire, and Attic Suppression
The garage fire, spanning 570 square feet, showcased the efficacy of a 265 GPM flow from a 2.5” handline in full blade mode, demonstrating the HEN 265's ability to efficiently suppress fires and handle attic extension with a 160 GPM blade stream through a ceiling opening in the living room.
Floorplan
Note: In the footage between 3:00 and 3:10, the 265 GPM BLADE's pre-distributive effect on application captures surfaces orders of magnitude better than a straight or solid tight stream of similar GPM and nozzle pressure. Similarly, from 4:00 to 4:14, the BLADED stream picks up ceiling joists, rafters, and multiple rafter-bay decking easily in a couple of passes.
Structure Fire Demonstration
Three Room Fire With Vent
Using a 160GPM wide BLADE stream in a vertical orientation, this fire suppressed multiple fully flashed-over rooms, requiring an active advance from the living room to the hallway, bathroom, and bedroom to ensure complete suppression without allowing fire to develop behind the nozzle team.
Floorplan
Note: The BLADE's actions from 2:46 to 2:52 in the main room: 6 seconds to fully capture a large space, 4 sweeps to full surface interaction, and a few progressive sweeps fully lift heat, with no viable hot spots for re-ignition after advance risk visible in TIC view. At 3:19, coating, cooling, contraction, and lift with good levels of air entrainment are firmly developed for searching members, and by 3:51 initial suppression is so complete that a member of the suppression team can fully stand in the large room visible in TIC footage.

Three Room Fire, Open Floor Plan
In this demonstration of a common open floor plan, three fully flashed-over rooms interconnected without barriers allowed a large-area fire, which was suppressed effectively using a 160 GPM wide-blade stream operated horizontally from the exterior entry door until all rooms were fully suppressed.
Floorplan
Note: From 2:36 to 2:50, during entry flow, the global impact of the BLADE’s pattern is downstream along pathways in an open floor plan. The BLADE's wet center and wide arc capture most downrange surfaces with minimal effort. Global suppressive effects are clearly seen in windows that are remote from the nozzle position, with cessation of vent point ignition and an established clean neutral plane (good air in, bad air out). Perhaps the most telling of all is the kitchen TIC view, which shows lift remote from the nozzle position at the initial 2:50 flow.
