... 2 Safety
... Overview of dangers
Hot surfaces
During operation of the probe gas sampling system surfaces and
parts get hot.
This means:
• Danger of burning due to hot surfaces during and after
operation of the system.
Associated warning sign in this operating instruction:
WARNING
Hot surfaces
Danger of burning due to hot surfaces during and after
operation of the probe gas sampling system.
• Do not touch the probe gas sampling system during and
after operation.
• Do not touch the probe 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 hot sampling filter
– the entire 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.
Harmful gases at the duct opening
When the shutter is open, gases flow out of the rotary kiln duct
opening that may be harmful to health.
This means:
• Danger of poisoning due to harmful gases.
• Danger of burning due to jets of flame at the duct opening.
Associated warning sign in this operating instruction:
WARNING
Hot surfaces, hot gases, jet flames
Risk of burning due to jet flames and hot gases at the
uncovered duct opening when the rotary kiln is in operation.
• Preferably install or remove the probe when the rotary kiln
is out of operation.
• If you install or remove the probe 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.
Hot cooling water
During operation of the probe gas sampling system, the cooling
water in the cooling system gets very hot.
This means:
• Danger of scalding in the event of contact with the hot
cooling water.
• Danger of burning in the event of contact with the cooling
water tubes.
Associated warning sign in this operating instruction:
CAUTION
Hot cooling water
Danger of injury to skin and eyes in the event of contact with
hot cooling water
• Avoid contact with the cooling water as it is hot.
• In case of accidental contact with hot cooling water wash
off immediately with cold water.
• Contact medical specialist according to local regulations.
• If hot cooling water gets in the eyes despite protective
glasses, rinse them thoroughly under cold running water,
holding the eyelids open. Contact medical specialist
according to local regulations.
Anti-freeze in the cooling water
The cooling system can contain cooling water with anti-freeze in
regions experiencing below freezing point temperatures.
This means:
• Danger of injury to skin and eyes in the event of contact with
anti-freeze.
Associated warning sign in this operating instruction:
CAUTION
Harmful anti-freeze
Danger of injury to skin and eyes in the event of contact with
cooling water or anti-freeze.
• Avoid contact with the cooling water and the anti-freeze.
• In case of accidental contact of cooling water or anti-
freeze with skin, wash off the skin immediately with water
and soap. Contact medical specialist according to local
regulations.
• If cooling water or anti-freeze gets in the eyes despite
protective glasses, rinse them thoroughly under running
water, holding the eyelids open. Contact medical specialist
according to local regulations.
• Observe instructions in the anti-freeze manufacturer's
safety data sheet.
