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.)
Excellent explanation of the procedure and the risk of entry. Lately some PSC Officers are listing as an observation if the FF take out is Glove to check the surface of the door..you are supposed to dom it with your glove on,,as per the PSC officer...solution? we got a digital laser thermometer to check whitout ouching any surface.
Thousand thanks for your positive feedback. There are different opinions on the question if you should take off the glove. In the end it depends on the situation and the risk involved. When you are inside a smoke-filled or burning compartment, you should indeed definitely leave your gloves on. However, using a laser thermometer or - even better - a thermal imaging camera is definitely the best option. Totally recommend. Best wishes, Marie from the Mayday Academy
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.
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
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

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
