well I did get a look at him and when the police came after the FD did I gave it to them he left came back with a picture of a guy sitting on the ground but I couldn't fully ID him it looked allot like him but I wasnt totally sure and apologized to there RCMP but when I left to head home I spotted him just down the road and it was the same guy in the picture who I recognized allot easier because of his Body language which you dont get from pictures plus he was on the same mountain bike there I think might be some street justice happening because the other homeless in the area where getting rousted while searching for him plus I told the officer to tell my place I work to give them access to there security cameras it would show the person for a few seconds turning around close to the gate.Typical fire extinguishers will empty in about 1 min. I would expect a larger extinguisher, in weight, would last a bit longer, but I wouldn't count on it. I hope you got a picture or a good look at the dickhead, and reported him to the police. Some people need to be jailed before they kill someone, and this person sounds like a candidate.
90% of fire extinguishers are rated ABC. They cover most fire issues. Most regular size extinguishers should last 1-2 minutes of constant spray. Bigger 2' ones should last 3-5 minutes.shoot at base of fire and use correct class of fire extingusuer of fire
You did it all perfectly in a time when most would panic.I am pretty sure I know how to use a fire extinguisher it was very windy and it was powder I wasn't about to run around the whole building looking for liquid because there probably wasn't one inside the building they are all chemical and the base of the fire was about 4 metres across in about 10 seconds and spreading rapidly then factor in the trees around with sap seeping from them which is also fuel plus the 1metre+ tall grass across the street just waiting for the wind to shift and catch a spark hehe I just needed to contain it long enough for the fd to get there and was extremely lucky that for some strange reason the wind stopped almost exactly when the extinguisher ran out but picked up again to it 60-70Km\h gust when the fd arrived it was one of those you dont think you do moments just react like a ball being thrown at your face and without thinking you catch the ball ( or at least I do some duck others just get hit in the face) .
I really dont get how people can do such things
