You may have seen me at a service station near you. It's always a Saturday morning, and I go to the back of the car, lift out an old plastic crate (dare I say milk crate?) holding three Victa fuel cans, plonk the crate on the ground and set about filling them. I carry three at once because I need both two-stroke and four-stroke fuel and I like to minimise my trips to servos.
You won't see me do this again because I discovered yesterday that not putting the mower can on the ground while filling it can ignite the petrol, which would put paid to my mowing plans for the day. I came across this after I read that a woman caused a fire that destroyed her car at the weekend when she held a can off the ground while she filled it with petrol. She hadn't taken any notice, the article reported, of the safety sign warning her to put the petrol container on the ground.
I've discovered, in an interview with Service Station Association chief Ron Bowden, that if the mower can is not earthed to ground static electricity on the can may spark to the petrol nozzle, and whooomp. Something else I didn't know is that it is important for the same reason that we keep our hand on the nozzle handle when filling our car. The reason, Mr Bowden explains, is that the fuel-pumping process is designed to drain static electricity from the car and the person to the nozzle to the bowser to earth to prevent sparks.
Nonsense? That's my initial reaction to most warnings of this nature, but I know that often on hot windy days a spark flies between my fingers and the car as I touch it.
I've never seen a sign warning us to keep our hand on the nozzle handle, and I've never seen a sign warning me to put the mower cans on the ground. Or, if I have seen such signs I've never read them. Do sensible people read warning signs? Do they need to?
