and distribution areas, and chemical plants. In addition, adhere to restrictions in areas where blasting operations are in
progress. Before using your device, watch out for areas that have potentially 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 lique ed petroleum gas (such as propane or butane) whether this device can be safely used in their vicinity.
