Electrical Hazards - Agilent Technologies 5800 User Manual

Safety Practices and Hazards
Gas cylinders must be stored and handled strictly in accordance with local safety
codes and regulations. Cylinders must be used and stored only in a vertical
position and secured to an immovable structure or a properly constructed cylinder
stand. Move cylinders only by securing them to a properly constructed trolley.
Use only approved regulator and hose connectors (refer to the gas supplier's
instructions). Keep gas cylinders cool and properly labeled. (All cylinders are fitted
with a pressure relief device that will rupture and empty the cylinder if the internal
pressure is raised above the safe limit by excessive temperatures.) Ensure that
you have the correct gas before connecting it to the instrument.
The primary gas used with the spectrometer is argon, which is the conductive gas
for the plasma. Argon or nitrogen can be used as the polychromator purge gas.
Other gases may be required for future options and accessories. Use only
'instrument grade' gases with your spectrometer.
If using cryogenic gases (for example, liquid argon), prevent severe burns by
wearing suitable protective clothing and gloves.

Electrical Hazards

The spectrometer system and some accessories contain electrical circuits,
devices and components operating at dangerous voltages. Contact with these
circuits, devices and components can cause death, serious injury or painful
electric shock. Panels or covers which are retained by screws on the spectrometer
and accessories may be opened only by Agilent­trained, Agilent-qualified or
Agilent­approved field service engineers (unless specified otherwise). Consult the
manuals or product labels supplied with your personal computer (PC), monitor,
printer and water-cooling system to determine which parts of those systems are
operator-accessible.
Connecting the Agilent ICP-OES to a power source that is not equipped with a
protective earth contact creates a shock hazard for the operator and can damage
the instrument. Likewise, interrupting the protective conductor inside or outside
the Agilent ICP-OES or defeating the power cord ground creates a shock hazard
for the operator and can damage the instrument.
