Danger Where / in what situa-
tion does the danger
arise?
Preventive action
Risk of burning due
to falling or spall-
ing 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
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.
Risk of burning due
to hot surfaces, hot
gases, jet flames
At the duct opening
when inspecting and
cleaning the wall tube
 Preferably inspect the
wall tube when the rotary
kiln is out of operation.
If you check or clean the wall
tube when the rotary kiln is
in operation:
 Wear a face mask against
heat, heat-proof gloves
and protective welder's
clothing and respiratory
protection against toxic
gases.
 Keep the time in which
the duct opening is open
as short as possible.
Danger due to
harmful gases, jet
flames
Due to gases escaping
from the duct opening
of the rotary kiln

Ensure adequate ventila-
tion of the work place.
 Only enter the danger
area around the retractor
when the shutter is
closed.
 Lock the shutter before
commencing work, if this
is indicated.
 If work is unavoidable in
the area of the duct open-
ing, wear respiratory pro-
tection.
Risk of scalding
due to hot cooling
water
When working on the
cooling water system,
particularly:
 ventilation open-
ings

screw connections
 Do not perform work on
the cooling water circuit
until the gas sampling
system has cooled down.
