Danger Where / in what situa-
tion does the danger
arise?
Preventive action
Danger due to cur-
rent-carrying parts Electric components in
general, above all dam-
aged electric compo-
nents
 If you are not specialized
electrical personnel:
 Never open electric
components.
 Never touch damaged
electric components,
cables or the inside of
electric components.
 Only specialized electrical
personnel may work on the
electrical system.
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
 Never enter the danger
area around the retractor
during operation.

Do not touch these compo-
nents during and after op-
eration.
 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
a face mask against heat,
heat-proof gloves and pro-
tective welder's clothing.
Danger due to harm-
ful gases, jet flames If gases escape from the
duct opening on the
rotary kiln when the
shutter is open during
operation.
 Never enter the danger
area around the retractor
during operation.
 Ensure adequate ventila-
tion of the work place.
Risk due to hot
cooling water In the event of hot cool-
ing water escaping if an
error occurs
 Wait until the entire cooling
water has been evacuated
before approaching.
