Intrinsically safe mobile phones must meet special battery design criteria in order to achieve UL, ATEX directive, or IECEx certification for use in explosive atmospheres. Only properly designed battery-operated, self-contained devices can be intrinsically safe by themselves. Other field devices and wiring are intrinsically safe only when ...

That’s like admitting to your mom all the bad things that you’ve done. I would rather know how he feels, that he feels he can be strong enough to get through this, because it’s a lifelong battle he’s going to have.
