OPERATIONAL WARNINGS

WARNING: Turn off your Two-Way radio when you are in any area with a potentially explosive

atmosphere, unless it is a radio type especially qualified for use in such areas. Sparks in a

potentially explosive atmosphere can cause an explosion or fire resulting in bodily injury or

even death.

WARNING: To avoid possible interference with blasting operations, turn off your radio when

you are near electrical blasting caps. In a "blasting area" or in areas posted "turn off two-

way radio", obey all signs and instructions.

NOTE

The areas with potentially explosive atmospheres referred to above include fuelling 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

potentially explosive atmospheres are often but not always posted.
