Emerson Rosemount CT4400 Reference Manual page 5

DANGER
FAILURE TO LOCK-OUT THE GAS HANDLING SYSTEM
Always lock out the gas handling system when shutting down the analyzer. Unauthorized operation of the gas handling system
when maintenance is being performed on the analyzer or its associated pipes/hoses may result in highly flammable gas being
released, causing fire or explosion.
Death or personal injury may result if this is not observed.
DANGER
FAILURE TO VENT SAMPLE GAS.
The sample gas in the system must be vented to prevent fire or explosion during maintenance and to prevent damage to the
analyzer during startup.
The sample gas in the pipes leading to the analyzer must be purged to prevent hazards to personnel during maintenance. Purging
the sample gas must be done in accordance with the safe working procedures for the site.
Allow the analyzer and system for returning the sample gas to run for five minutes to allow any sample gas in the system to be
returned to the exhaust.
WARNING
LASER OPTICAL RADIATION EXPOSURE HAZARD
The Rosemount CT4400 is a Class 1 laser product. The lasers are fully enclosed so that no hazardous radiation is accessible under
normal operating conditions.
Opening the analyzer and attempting to perform adjustments or procedures other than those specified in this manual may
result in hazardous optical radiation exposure to personnel.
WARNING
HAZARDOUS SUBSTANCES
The analyzer may contain hazardous substances. Always handle the analyzer assemblies and components with extreme caution.
Wear personal protective equipment (PPE) when handling the equipment.
Gas handling components within the analyzer contain particulate matter residue from the sample gases. Over the life of the
analyzer, the concentration of particulate matter will become enriched within the gas handling components. When performing
repairs and maintenance on the analyzer:
— Handle used gas handling components with extreme caution.
— Avoid direct skin contact with used gas handling components.
— Do not smoke, drink, or eat in the work area.
— Wear goggles or eye shields.
— Wear a suitable face mask to protect against inhalation of particulate matter.
— Do not wet fingers, eyes, or any exposed skin.
— Pack used gas handling components for disposal in sealed packaging and label them Contaminated.
Dispose of contaminated items as hazardous material in accordance with applicable local, national, or international health and
safety regulations and pollution regulations.
