Verifying Safe State - Agilent Technologies Graphite Tube Atomizer GTA 120 User Manual

Safety Practices and Hazards
The safety practices described below are provided to help you
operate your instrument safely. Read these safety practices
thoroughly before attempting to operate the instrument and always
operate the spectrometer in accordance with these safety practices.
The GTA uses interlocks and covers which are designed to prevent
accidental contact with any of the potential hazards. It is good
practice, however, to develop safe working habits which do not
depend upon the correct operation of the interlocks for safe
operation. It is essential that no interlock or cover is bypassed,
damaged or removed.
Fumes generated by the GTA can be hazardous, and must be
extracted by an exhaust system. Ensure that an exhaust of the
appropriate type is fitted, as specified in the pre-installation
instructions. It must be vented to the outside air, never within the
building. Regularly check the exhaust system by smoke test to ensure
that it is functioning correctly. Always switch the exhaust fan on
before operating the instrument.
WARNING Noxious Gas
An exhaust system must be used with an Agilent AA flame and furnace
instruments to remove hazardous and toxic gases.
If the equipment is used in a manner not specified by the
manufacturer, the protection provided by the equipment may be
impaired.
