Safety instructions

Take into consideration the following safety instructions for all
actions related to operation:
DANGER
Danger to life due to live parts!
• Only specialized electrical personnel may work on the
electrical system.
• Disconnect the probe gas sampling system from the
power supply before working on the electrical
components.
• Observe national regulations pertaining to electrical
equipment.
WARNING
Mechanical, thermal and material dangers
Risk of injury in the area of the probe gas sampling system
due to moving or falling parts, anti-freeze, lubricating oil.
• Wear general personal protective equipment:
• Closed overalls with long trousers and long sleeves
• Safety shoes (preferably boots covering ankles)
• Safety gloves suitable for mechanical work Safety glasses
• Protective helmet
• If necessary, additional protective equipment if prescribed
by the operator.
WARNING
Gas sampling probe movements
Risk of crushing around the retractor due to gas sampling
probe movements.
• Before commencement any work on the probe gas
sampling system, turn the Safety switch to "Off" and
secure the service switch against unauthorized switching
(with a padlock).
• Additionally press the EMERGENCY-STOP switch before
working on the retractor or probe.
• Do not enter the danger area around the retractor until it
is at standstill and the warning lamps and buzzer are off.
• Never stand in the danger area around the retractor when
the protective installation is closed.
• When the warning lamps light up or the warning buzzer
buzzes, leave the danger area around the probe retractor
immediately as the probe is about to move at any
moment.
• Press the EMERGENCY-STOP switch immediately if anyone
is still in the danger area around the retractor after the
warning lamps light up or the warning buzzer buzzes.
WARNING
Pressurized system dangers
Risk of injury in the area of the probe gas sampling system
due to pressurized pneumatic system.
• All pneumatic equipment connected must be fulfilling local
standards for safety and usage.
• Periodic inspection/approval of installation according to
local standard.
• Any damage to a pneumatic equipment will require a
replacement in order not to compromise safety integrity
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.
WARNING
Falling or spalling hot material
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 any material
resting on the probe 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.
WARNING
Harmful gases, jet flames
Danger due to harmful gases and jet flames in the area of the
duct opening while the probe is moving in or out
• Never enter the danger area around the retractor during
operation.
