Gas Hoses And Connections; Ultraviolet Radiation - Agilent Technologies 240 Series AA User Manual

Safety Practices and Hazards
Remember that for cylinder connections, left-hand thread fittings are used for fuel;
right-hand thread fittings are used for support gases.
When your analytical program is complete, or at the end of the working day,
always ensure that all gas supplies are turned off at the cylinders.

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

Flames, hollow cathode lamps, and deuterium lamps emit hazardous ultraviolet
radiation. 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.
