Make sure it's mounted nicely, I've had one of these discharge in my face whilst I was driving along a dual carriageway, I **** myself. There was a massive bang (the thing falling over lol) and then the whole cab filled with what I thought was smoke lol I thought a petrol mower on the back had blown up. Given I knew how many gas canisters and litres of petrol were on the van I have never run so fast in my life LOL.
p.s. never let someone else load your van lol
