Gas Hoses And Connections - Agilent Technologies 55B AA User Manual

Safety Practices and Hazards
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.
If air is supplied from a compressor, all moisture must be extracted
from the air before it is supplied to the gas control module. Moisture
can affect the internal tubing and components of the gas control
system and create a potentially hazardous situation.
Use only approved regulators and hose connectors.
Never attempt to refill cylinders.
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.
