Dry powder is a good allrounder and you normaly get a couple of shots from it if the fire re-ignites, only problem it's messy... but so is a fire. powder can also be a laxative :lol:
The throwable produces CO2 and ammonia, so like dry powder, there will be no cooling of the fuel so re-ignition is likely. Would you have a second one in the house, to throw again if it did flare up again or for a secondary fire in another room? They don't show it used on liquid, which could be fun :shock:
Talkin of fire extinguishers my brother inlaw and his mate thought it would be funny to set the powder 1's off in there rooms when they was in egypt with the Missus lol
