Fan Placement

The operator of the fan should not wear lose clothes or ties that could tangle in the fan

Always be sure you understand the hand signals of the Crew Chief and/or Pilot

My preference is to place the fan on the left side of the basket
as the On/Off Switch is easily reachable by the pilot during Hot Inflation

On Final Point. The fan needs to be pulled away from the basket after inflation, if not the basket could swing into the fan by wind thus causing the fan to tip over and dump gasoline on the hot engine thus causing a fire
