Compressed Gas Hazards
All compressed gases (other than air) can create a hazard if they leak
into the atmosphere. Even small leaks in gas supply systems can be
dangerous. Any leak (except that of air or oxygen) can result in an
oxygen-deficient atmosphere, which can cause asphyxiation. The
area in which cylinders are stored and the area surrounding the
instrument must be adequately ventilated to prevent such gas
accumulations.
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.
