Fire extinguishers

[Old Wal]

Mudnut this is the biggest downfall of dry chem we had to fluff up our 250kgs vessels every quartely and our trucks were inside the airport .Diesel vibration will pack a dry chem in short time as well .solution invert extinguisher and give a few tapes on the corner of the tire
tread and shake like a race car winner on the podium .Winner

This too was pointed out to me when I did a dangerous goods course many years ago, We had to have an inspection list or schedule that included shaking up the powder. If you have the space an extinguisher that has a hose attached is better . If you have an under dash fire you can aim the hose up under the dash - dry powder extinguishers don't work for long upside down or on their side. Likewise if you have an engine bay fire you can just pop the bonnet ( without lifting it ) , insert the hose and give a quick blast to quell the fire a little . Saves getting a face full of flames
