Safety Practices and Hazards
14 Agilent 55B AA Spectrometer User’s Guide
Compressed gases and cylinders
All compressed gases can create a hazard. The volatile nature of the gases used
with this equipment increases this hazard.
WARNING
Explosion Hazard, Fire Hazard, Noxious Gas
Even small leaks in gas supply systems can be dangerous.
A leak can create an explosion hazard, a fire hazard, or can result in an oxygen-
deficient atmosphere.
Such hazards can cause death, serious injury, asphyxiation, anesthetic effects,
and serious damage to equipment and property.
Cylinders must be:
Stored and handled strictly in accordance with local safety codes and
regulations.
Used and stored only in a vertical position.
Secured to an immovable structure or a properly constructed cylinder stand.
Stored in an adequately ventilated area to prevent toxic or explosive
accumulations.
Moved only on a properly constructed trolley.
Keep cylinders cool. This rule applies to every cylinder of compressed gas.
Cylinders have pressure relief devices that will release the contents of the
cylinder if the temperature exceeds 52 °C (125 °F).
Ensure that all cylinders are clearly labeled so that there can be no doubt
about the contents. If the cylinder label is not legible, do not use the cylinder—
return it to your supplier.
Always ensure that you have the right cylinder before connecting the cylinder
to the instrument.
Use only approved regulators and hose connectors.
Never attempt to refill a cylinder.
