Water will only work when the door is very hot (above 100 centigrade). Otherwise, it will not evaporate

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

Hi Richard, many thanks for the input!

Hi, sorry for the late reply. We had been super busy with the STCW courses recently. Exhaust ducts are part of machinery spaces so it should be A60

@@MaydayAcademy thank you 😄

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

Glad that you liked it ❤

Yes. Totally right. We did not show the shifter.

Yes, it will. That is why it must always be done in a coordinated attack. That means that we must put water on the fire or in the compartment immediately when we start ventilating. The advantage is that the flow path will draw our water and steam into the fire where is can take effect. It also increases our visibility. These advantages outweigh the effect of oxygen supply. Hope that reply was helpful. If you have further questions, please reach out. Best wishes, Marie

@@MaydayAcademy thank you. And what to do in enclosed spaces

Thank you so much for your feedback

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

Thank you so much. Glad you like it ❤️

I used Blender for the 3D modelling. It is free and open source but takes some time to get your head around it. Best, Marie

Hi, thank you for the question. I only counts as class a if it is tested that no flames or smoke will go through for one hour

Thanks for your response.. So to comply A-0 class division this Bulkhead or deck should require thermally insulated with non- combustible materials? That for sure for A15, A30 & A60 need to be thermally insulated with combustible materials. Can you share video showing how it's look like this A0 & A60 deck/bulkheads and B Class division...

Thank you so much for your feedback. We are glad it was helpful
