Specific warnings
The following warnings can appear in the user manuals of particular
instruments and on labels affixed to them or their component parts.
Burst warning
This warning applies to Waters instruments fitted with nonmetallic tubing.
Mass spectrometer flammable solvents warning
This warning applies to instruments operated with flammable solvents.
Warning:
(Risk of exposure to biological agents that can pose a serious
health threat.)
Warning:
(Risk of tipping.)
Warning:
(Risk of explosion.)
Warning:
Pressurized nonmetallic, or polymer, tubing can burst.
Observe these precautions when working around such tubing:
• Wear eye protection.
• Extinguish all nearby flames.
• Do not use tubing that is, or has been, stressed or kinked.
• Do not expose nonmetallic tubing to incompatible compounds like
tetrahydrofuran (THF) and nitric or sulfuric acids.
• Be aware that some compounds, like methylene chloride and
dimethyl sulfoxide, can cause nonmetallic tubing to swell, which
significantly reduces the pressure at which the tubing can rupture.
Warning:
Where significant quantities of flammable solvents are
involved, a continuous flow of nitrogen into the ion source is required to
prevent possible ignition in that enclosed space.
Ensure that the nitrogen supply pressure never falls below 400 kPa
(4 bar, 58 psi) during an analysis in which flammable solvents are used.
Also ensure a gas-fail connection is connected to the LC system so that
the LC solvent flow stops if the nitrogen supply fails.
