I have been looking at the use of APRS over packet radio and noted that many
Amateurs now have mobile installations in their cars both for fun and to
assist in tracking the vehicle should it get stolen.

This is quite an appealing idea however I do have one concern that I hope an
experienced mobile APRS user could assist me with.

When one visits petrol/gas stations here in Australia one sees signs saying
to switch off one's mobile phone as the electromagnetic radiation could
cause a spark and ignite fuel vapour. It has made me wonder how to make APRS
safe so that should you be filling up your car at a gas station you can be
assured that a regular APRS update from your mobile APRS setup won't run a
risk of causing a fire.

Have APRS users considered this possibility and what precaustions, if any,
are taken to deal with this problem?

This works well for me - Lean slightly forward, apply gentle pressure
with index finger to button on radio labelled PWR.
