Preparing the compressed-air supply
Risk of injury in the area of the gas sampling system due to moving or fall-
ing parts, hot surfaces, hot cooling water, anti-freeze, compressed air,
lubricating oil
Wear general personal protective equipment:
 Closed overalls with long trousers and long sleeves
 Safety shoes
 Safety gloves suitable for mechanical work
 Safety glasses
 Protective helmet
 If necessary, additional protective equipment if prescribed by the opera-

.
Other requirements are:
 The compressed air must be free of dirt and oil/water droplets.
 At ambient temperatures below 0 °C make sure that the compressed-air
supply cannot freeze.
