Areas with potentially explosive atmospheres include fueling areas
such as below decks on boats, fuel or chemical transfer or storage
facilities, areas where the air contains chemicals or particles such as
grain, dust, or metal powders, and any other area where you would
normally be advised to turn off your vehicle engine. Areas with poten-
tially explosive atmospheres are often posted, but not always.

Nearly every electronic device is susceptible to electromagnetic
interference (EMI) if inadequately shielded, designed, or otherwise
configured for electromagnetic compatibility.
