Areas with a potentially explosive
atmosphere are often but not always
clearly marked. They include below deck
on boats; chemical transfer or storage
facilities; vehicles using liquefied
petroleum gas (such as propane or
butane); 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.
Failure to observe these instructions may
lead to legal action.
