From the Mailbag:


Do you know if there is a requirement for explosion proof cell phones and pagers. I am concerned about employees working in a Class 1, Division 1 atmosphere. Employees working in a hazardous location are required to carry either a cell phone or pager for health reasons. Thank you for your attention to this. (Jack Peckham)

Pagers and portable radios are available in "intrinsically safe" versions which can be used in Class 1 Div 1 areas. I'm not sure about cell phones.

I found this post while searching for information on cell phone use around car fuel dispensers. Anyone have any more info about this? I have heard that it (cell phone use) could cause a fire while filling, like that horror story about using a plastic container laying in the back of a pickup. Any links to the true stories here?

Thanks, Rick Miell

You might try contactacting Mine Safety & Health Administration and see if they know of a "permissible" pager & cell phone. Permissible is their wy of saying it won't ignite a methane/air mixture.
Few things are harder to put up with than the annoyance of a good example.

Oil companies are extremely concerned about cell phone use and gas pumps. I forget which company but a major oil company has had several deaths that I know of attributed to cell phones ringing. If you notice your surrondings while fueling up, you'll notice a decal telling you to shut off cell phone before fueling.
Haven't heard of a pager problem.

Boy, can you imagine how big a Class I, DivI, cellphone would be??
And, having to figure out a way to "open it up" to place a call??

I just had to add some sick humor to this thread.

Seriously, the majority of the chemical plants that I have to go to for inspections, require that you leave phones, pagers & radios at the point of entry.

Trying to picture how a pager would help in an emergency...

"Bang once on the big steel pipe if your OK, twice if you are hurt..." er, something like that.

As to the original question, posted in 2001, I'm not sure
