Potentially Explosive Atmospheres
Do not charge your batteries or operate your battery charger within the proximity of any potentially explosive

but not always, clearly marked and include the following:
Gas stations
Below deck on boats
Fuel or chemical transfer/storage facilities
Areas where air may contain chemicals or particles, such as grain dust, or metal powders
Any area where you would normally be advised to turn OFF your motor vehicle
Do not bring your M1503 pager or basic dock into areas with
potentially explosive atmosphere.
