Safety Practices and Hazards

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) can result in an oxygen-
deficient atmosphere which can cause asphyxiation. The storage area
must be adequately ventilated and must comply with the rules and
regulations imposed by the local authorities responsible for such use
in the workplace.
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.
If gases are to be plumbed from a remote storage area to the
instrument site, ensure that the local outlets are fitted with stop
valves, pressure gauges and suitable regulators that are easily
accessible to the instrument operator. The gas outlets must be
provided within 1.5 meters (5 feet) of the Agilent 4100 MP-AES.
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 cylinder before connecting it to the MP-AES.
If using cryogenic (liquid) gases (for example, liquid nitrogen or
argon) prevent severe burns by wearing suitable protective clothing
and gloves.
