[A] The safety drive did not apply merely to offshore operations: employees at some British oil-company offices are now required to use handrails while walking up and down stairs, for example.

[ B] As a result, the company had to pay a huge amount of compensation to the families of the victims and law suits concerning those fires seemed to be endless.

[ C] A further complication was the rise of the internet, where hoax memos, many claiming to originate from oil companies, warned of the danger of using mobile phones in petrol stations.

[ D] This is particularly noticeable in Britain. The country that led the way in banning mobile phones at petrol stations is also the country that has taken the strongest line on the safety of mobile-phone use by children.

[E ] Despite the lack of evidence that mobile phones can cause explosions, bans remain inplace around the world, though the rules vary widely.

[ F] By the late 1990s, however, phone makers--having conducted their own research-realized that there was no danger of phones causing explosions since they could not generate the required sparks.

[ G ] This seems to have become more common as plastic car interiors, synthetic garments and rubber-soled shoes have proliferated.
