explosive atmospheres that are often, but not always, clearly
marked. Such locations include areas below the deck on boats,
chemical transfer or storage facilities, and areas where the air
contains chemicals or particles such as grain, dust, or metal
powders. Ask the manufacturers of vehicles using liquefied
petroleum gas (such as propane or butane) whether this device can
be safely used in their vicinity.
