Petrol pump stopping

mikey72

I never follow the no parking in cycle lanes, if that helps.

A dropped cigergette will not ignite a pool of petrol because the liquid dissipates the heat too quickly. A cigergette will ignite petrol VAPOR. Which is why it's not a good idea to smoke near the pumps.

Petrol vapor is much more flammable than the liquid itself.

If I had an actual problem I can assure you I wouldn't be seeking advice on the MoneySavingExpert Moroning forum :rotfl::rotfl::rotfl::rotfl::rotfl:

Pulled in at Shell this morning to get some petrol and was checking flight time on my phone while fuelling.

get a life and put the dam. phone down for 5 minutes !

It hasn't been proved or disproved

you offering to be a test dummy ?
I can see the headlines next week

Man using mobile phone at petrol station sues after catching fire whilst on the phone filling his car with petrol !

The outcome would be nil pounds as he ignored the warning signs :T

Well you always seem to be asking after the fact. I ran a red light, should I not do this? I had my phone at petrol pump... d'oh.

I'm sure most of the people you class as morons wouldn't be so moronic as do some of the things you've done

The fuel to air ratio for a stable burn (in a car engine) is 14.7 to one in favour of air..... It is therefore oxygen that is the primary component.

Quoting this doesn't make an iota of difference to the basic chemistry of combustion - oxygen still doesn't burn.

Just in case you're interested, let me have one quick stab at explaining. If you light a match in a room with a higher concentration of oxygen than normal the match will burn more vigorously (it is the match that burns, not the oxygen). If on the other hand you light a match in a room containing, for example, a high enough concentration of methane (mixed with air containing oxygen), you'll end up with a room full of burning methane (a fireball if you like), albeit a brief one. In both cases oxygen in used up, but it is the fuel (the match in the first example and the methane in the second) that burns.

so basically you are saying dont go in a room full of old farts and light a cig:D

Just want to add my tuppenceworth here. Perhaps I can shed some light on the subject generally. Usually, any electrical equipment to be used in a hazardous area, would have to be explosion proof. This would mean that the casing of any item would not allow ingress of flammable vapour, and therefore, would not expose a spark to any vapour. Torches used by the fire services are marked ex for explosion proof. Similarly, all the electrics of a forecourt fuel pump would be sealed to prevent any spark.

Petrol has a flashpoint of around -40C. Paraffin would be around +40C. At normal temperatures, petrol will vaporise rapidly if exposed to open air, and will travel along the ground because it is heavier than air. It will also pool in low areas, i.e. pits and basements. When petrol vapour is mixed with oxygen, (air), it will form an explosive mixture. This mixture is more explosive at lower concentrations, i.e. weaker petrol to air mixtures. This is what makes it work in car engines. When I say it is an explosive mixture, I mean just that. A little petrol with a lot of air will go off like a bomb with just a spark.

Finally, regarding dropping a lit cigarette onto a pool of petrol, well, if it lands in the middle of the pool it will go out, but if it lands on the edge, or if the fuel has spread nice and thinly, then it will most definitely ignite the petrol. I don't much care for the opinion of the university of kent guy. I will rely on my own experience of 27 years in a fire service.
