Thank you RKS! Real science at work here. I was hoping someone would find a report that was better than my anecdotal links. That IEEE PCIC paper should put the whole subject to bed.

“Concern about cellphone safety at gas stations
arose from anecdotal reports circulated on the internet and by the media.” cite: “Cell Phones Pose No Gas Station Hazard”, IEEE Spectrum Magazine, p6, dated April, 2004

Also see 2007 IEEE PCIC Paper Abstract, “Additional testing and analysis of the high risk mobile phone components indicated a very low probability of ignition even under ideal conditions. A Monte Carlo simulation of the probability model estimated the odds of a mobile phone causing a fire or explosion in a Category 3 -Zone 2 Explosive Gas Atmosphere as being 1.16E-06; or one in a million”

Battery powered equipment such as mobile phones, pagers, and cameras represent a potential ignition source.

Shell takes the safety of its customers and retail staff very seriously. For this reason, although the risk associated with mobile phone use at retail sites is very low, Shell was the first in the oil industry in Malaysia to put up notices at pump islands to request motorists to switch OFF their mobile phones when refuelling at the station.

I don’t think they’d admit to the problem if it wasn’t a possibility.
