Preventive action
Danger due to cur-
rent-carrying parts
When working on elec-
tric components
 Only specialized electrical
personnel may work on the
electric system.
 Disconnect the gas sam-
pling system from the pow-

the connection and terminal
box.
 Observe national regula-
tions pertaining to electrical
equipment.
Risk of burning due
to hot surfaces
The following compo-
nents are very hot during
and after operation of
the gas sampling sys-
tem:
 the cooling module
 the heated sample
gas lines
 the connection box
for the heated sample
gas line on the retrac-
tor
 the heated sampling
filter
 the entire gas sam-
pling probe
 the metal structure of
the retractor
 the shutter of the duct
opening
 Do not touch these compo-
nents during and after op-
eration.
 Do not touch these compo-
nents until they have
cooled down to less than
50 °C.
 If it is unavoidable to touch
hot components, wear a
face mask against heat,
heat-proof gloves and pro-
tective welder's clothing.
Risk of burning due
to falling or spalling
material.
After the probe moves
out of the rotary kiln, hot
material may fall or spall
off the probe.
 Never enter the danger
area around the retractor
during operation.
 Do not approach the re-
tracted probe until it has
cooled down.
 If it is unavoidable to ap-
proach the hot probe, wear
