I agree to most. Few things though, If I may. It's better to close the door after a shot of water. Close the door, let the steam do it's work in stead of escaping through the opened door. Wait 30 seconds or so, and repeat if needed . Chances are that the fire is already extinguished after second/third attempt. Then a minor detail: Watertight doors open when dogs or handles are lifted. Pushing them down closes the door. (But that is of less importance for an otherwise beautifully made video. My compliments.)
Just a quick reminder to all shipboard firefighters. The dogs should be opened hinge side first in the order of top, bottom, middle. Then latch or opening side in the same order top, bottom, middle. Control the door while opening away from you thus protecting you from a pressurized compartment/backdraft.
The platinum solution is to have a Thermal Imaging Camera to check the door for hotspots, if applicable open the door and take a screenshot to ascertain where the neutral plane lies. Then get in and crack on with gas cooling
I’m interested in the origins of the concept of using a spray pattern for the indirect attack. I have been taught in more than one training centre to use a straight stream, aiming for the deck head directly over the fire. The straight steam is intended to not disturb the thermal layering. For sure, any kind of a spray pattern moves a lot of air, which is feeding the fire. is there a reference material for not using the straight stream?
Hi Jeff, thank you for your comment. In case you do an external indirect attack, you can use a straight stream for a window impulse. In an interior attack, however, we never use a straight stream. In the video, we talked about gas cooling. Gas cooling is most effective with a wide spray pattern due to the larger water surface. Moreover, a straight stream could penetrate through the gas layer, hit the deck head, evapourise and push the hot gases down in the fire team. That is why we recommend a spray pattern. Will look up references and Postboten here these days. Hope this answer is helpful. Best, Marie

Hi Richard, many thanks for the input!
Why place the back of the hand on the door when you can paint the door with water?
Water will only work when the door is very hot (above 100 centigrade). Otherwise, it will not evaporate
