Does one run risk of an explosion when pressing phone beside a gas cylinder.Is there any particle in our phone that can ignite and cause explosion when coming near a cylinder.Although i have read stories about gas explosion where it was claimed that it is caused by careless usage of phone beside a cylinder and while some say it is not because of the phone.And moreover,even at gas depot there are always warning not to on or operate phone.Please kindly enlighten me and those who may also need clarification on this.
