Let's be clear about this: the government advice was stupid. Maude should never have advised storing petrol at home. In an independent act of stupidity of far greater magnitude, a woman died after exposing petrol to an environment with a naked flame in it.
Should the government be criticised for the advice they gave? Definitely. Should they be blamed for this woman's tragic ignorance? No.
I thought Maudes advice was pretty sensible. I personally had no idea that a jerry can was specifically 20 litres or even that keeping 20 litres of petrol (in one can?) was illegal. Like the word "hoover" is synonymous with "vacuum cleaner" then I reckon most people just think a jerry can is a normal 5 litre can of petrol/fuel.
And if the media have such a huge problem with people putting petrol in a can (for the "strike") how do they resolve the milions of people who keep petrol in the garage for mowers etc?
Decanting your petrol into a jug by a lit cooker - that's a bit daft and I don't think Maude ever suggested doing that.
Since the last fuel strike I've always kept 3 x 20 litre cans of diesel at home... but btw it's also not sensible to keep petrol in any quantity because it actually goes "off" in time (loses it's octane rating) and could damage your engine.
