Safety considerations
Some reagents and samples used with Waters instruments and devices can pose chemical,
biological, or radiological hazards (or any combination thereof). You must know the potentially
hazardous effects of all substances you work with. Always follow Good Laboratory Practice
(GLP), and consult your organization’s standard operating procedures as well as your local
requirements for safety.
Safety hazard symbol notice
The
symbol indicates a potential hazard. Consult the documentation for important
information about the hazard and the appropriate measures to prevent and control the hazard.
Considerations specific to the device
Power cord replacement hazard
Warning:
To avoid electric shock, observe these precautions:
• The power cord functions as the safety disconnect device. Position the equipment
so that you can reach the power cord easily.
• Use SVT-type power cords in the United States and HAR-type power cords, or
better, in Europe. For requirements elsewhere, contact your local Waters distributor.
• Do not replace power cords with inadequately rated power cords.
• Inspect the power cords for damage and replace them if necessary.
• Connect each module of a system to a common ground.
• Power-off and unplug a system module or stand-alone device before performing
any maintenance operation on it.
Flammable solvents hazard
Warning:
To prevent the ignition of flammable solvent vapors in the enclosed space of
a mass spectrometer’s ion source, ensure that these conditions are met:
• Nitrogen flows continuously through the source.
• A gas-fail device is installed to interrupt the flow of LC solvent should the nitrogen
supply fail.
• The nitrogen supply pressure does not fall below 400 kPa (4 bar, 58 psi) during an
analysis requiring the use of flammable solvents.
The gas-fail device for the RDa Detector is the Stop Flow cable connected to the LC. If the
nitrogen pressure falls below 400 kPa (4 bar, 58 psi), the instrument sends a stop-flow signal to
