Gas Hoses And Connections; Ultraviolet Radiation - Agilent Technologies AA Series User Manual

Gas Hoses and Connections

Even small leaks in gas supply systems can be dangerous. Any 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.
Use only approved regulators, connectors and fittings. If in any
doubt, consult your local gas supplier or your Agilent representative.
Ensure that all gas connectors and hoses are correctly assembled.
Arrange gas hoses so that they will not be damaged, stepped on, or
have things dropped on them.
Never use frayed or damaged hoses.
Perform leak tests at all joints and seals every day before the
instrument is used. Test for leaks with a brush and soapy water or a
proprietary leak-detecting solution. Never use a naked flame when
testing for leaks.

Ultraviolet Radiation

Hazardous ultraviolet radiation is emitted by flames, hollow cathode
lamps and deuterium lamps. This radiation can cause serious damage
to human eyes and skin.
Always wear safety glasses conforming to an approved standard, and
certified or otherwise warranted to protect the eyes from ultraviolet
radiation. Never look directly at the light emitted by a hollow cathode
lamp.
When using a flame, always operate your spectrometer with the
flame shield closed, and the sample compartment front panel and
chimney in place.
