The ministry’s working party stipulated also that spraying operations
should cease if the temperature rose above 80oF, a point heeded by Pest
Control whose air-conditioned cabs were kept below 76oF.
“This is eff ected by heat insulation and by trickling water over the
cab - a method often used in greenhouses in tropical countries,” said The
Engineer. “The spraying machine has to be frequently refi lled with water
and it is therefore a simple ma er to refi ll the tank on the air-conditioned
cab at the same time.
“As soon as the thermometer inside the cab registers a temperature
above 70oF, the operator turns on a tap, which sets the water-cooling
device in action.”
