I noted how difficult it was to relight the foam smothered fire. However i also noted that the second time it took much longer and the fire might have burned a great deal of the fuel by that point. Especially as fuel had been burned two times already from both of the tests. Not to mention evaporation or possible drainage into the ground. I'm sure the point was valid it's just that the lack of control in the experiment/test could have made the test look more effective that it should have been when it came to trying to relight the fire. Generally it's just me having a problem with holes in statistics. Good video, very informative.
Looks like a combination of powder and foam is the optimal choice. Powder for fast extinguishing the fire and than cover the area with foam to prevent reignition.
M.AKASH IQBAL Most foam extinguishers are AFFF (aqueous film forming foam) - they use surfactants in a water base to float above the fuel and suffocate it.
@@andison627 but those chemicals cause health problems ( it was named in a lawsuit !)at this point if the foam concept was belived to be a good idea so they are trying to designed safer version it seems
@@wcresponder lets see if I can find a link : here an an examply but you probably should seek out addtional youtube links : ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-FIU9luFuwSI.html
@@wcresponder of course the reason I switched to cold fire is it is a surfactant type that is advertised as an alternative to halon I think we are pretty sure that cold fire is a great product is why Nascar and the irl like it because it does not damage engine parts like dry chem will so its probably also easier in my home to clean up a liquid than a powder even if the powder it seems does not stick it still seems it can be diffcult to clean
*Before you do anything to FIGHT or extinguish a fire, call 000 for the fire brigade and evacuate everyone.* *Do NOT* breathe the by product fumes from the fire. *Do NOT* breathe Dry Chemical powder dust. *Do NOT* tackle a fire without first evacuating personnel.* If the fire is too large, *Evacuate.* *DO NOT* attempt to tackle a large fire. *If using a CO2 extinguisher, Evacuate the space - Danger of Asphyxiation. Do not hold the horn or cylinder - Danger of frostbite.* *If using a HALON extinguisher, Do not use in a confined space and evacuate at once as soon as the fire is out - Risk of poisoning.*
