danger of burning due to hot surfaces during and after operation of the gas
sampling system.
 Do not touch the gas sampling system during and after operation.
 Do not touch the gas sampling system until it has cooled down to 50 °C.
Specifically, do not touch
 the cooling module,
 the heated sample gas line,
 the connection box for the heated sample gas line on the retractor,
 the heated sampling filter,
 the entire gas sampling probe,
 the metal structure of the retractor,
 the shutter of the duct opening.
 If it is unavoidable to touch hot components, wear a face mask against
heat, heat-proof gloves and protective welder's clothing.
Danger of burning due to material falling or spalling off the retracted probe
 Never enter the danger area around the retractor during operation.
 Do not approach the retracted probe until it has cooled down.
 If it is unavoidable to approach the hot probe, wear a face mask against
heat, heat-proof gloves and protective welder's clothing.
Danger due to harmful gases and jet flames in the area of the duct opening
while the gas sampling probe is moving in or out
 Never enter the danger area around the retractor during operation.
 Ensure adequate ventilation of the work place.
Risk of scalding when hot cooling water escapes from the cooling system in
the event of a malfunction
 Wait until the entire cooling water has been evacuated before approach-
ing.
