Burst warning
This warning applies to Waters instruments fitted with nonmetallic tubing.
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: 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.
