A.1.1
Specific warnings
The following warnings (both symbols and text) can appear in the user manuals of particular
instruments and devices and on labels affixed to them or their component parts.
A.1.1.1
Burst warning
This warning applies to Waters instruments and devices fitted with nonmetallic tubing.
A.1.1.2
Biohazard warning
The following warning applies to Waters instruments and devices that can process material
containing biohazards, which are substances that contain biological agents capable of producing
harmful effects in humans.
Warning:
(Risk of exposure to a toxic substance.)
Warning:
(Risk of personal exposure to laser radiation.)
Warning:
(Risk of exposure to biological agents that can pose a serious health threat.)
Warning:
(Risk of tipping.)
Warning:
(Risk of explosion.)
Warning:
(Risk of high-pressure gas release.)
Warning:
To avoid injury from bursting, nonmetallic tubing, heed these precautions when
working in the vicinity of such tubing when it is pressurized:
• 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 compounds with which it is chemically incompatible:
tetrahydrofuran, nitric acid, and sulfuric acid, for example.
• Be aware that some compounds, like methylene chloride and dimethyl sulfoxide, can
cause nonmetallic tubing to swell, significantly reducing the pressure at which the tubing
can rupture.
Warning:
To avoid infection with potentially infectious, human-sourced products,
inactivated microorganisms, and other biological materials, assume that all biological fluids
that you handle are infectious.
Specific precautions appear in the latest edition of the US National Institutes of Health (NIH)
publication,
Biosafety in Microbiological and Biomedical Laboratories
(BMBL).
Observe Good Laboratory Practice (GLP) at all times, particularly when working with
hazardous materials, and consult the biohazard safety representative for your organization
regarding the proper use and handling of infectious substances.
