Safety
Gloves and a long sleeve shirt (or lab coat) are required to prevent burns. Dies die nut
holders and piston rods become extremely hot. They are designed to transfer heat quickly
to the sample being tested, and unfortunately this means they will transfer heat very
quickly to you as well. Even brief contact with a hot item can cause a serious burn. The
barrel swing arm and connecting lower barrel cover may also get fairly hot. However, at
barrel temperatures lower than 350
°
C these may not cause burns if touched for a brief
period. Keep the swing arm free of items since they will fall off during opening or closing.
Plastic pens or other items may also melt! Consider where dies or the die nut holder may
fall. If they are dropped on Nylon carpet or similar materials, they can quickly form holes.
Protective mats may be needed.
Your
DYNISCO POLYMER TEST
rheometer contains high voltages inside the rheometer base.
DO NOT remove this cover unless you are instructed to do so by a
DYNISCO POLYMER TEST
representative or are experienced with high voltage devices.
Be sure the outlet used to
power the rheometer is properly grounded.
If a thermometer is used to calibrate the temperature on the rheometer, it will contain
about 8 grams of mercury. Every lab with mercury thermometers or equipment containing
mercury must be prepared for breakage. Note that mercury exposed to air "evaporates" at
room temperature, producing an invisible, tasteless, odorless and dangerous vapor.
Thermometers have been used for decades in laboratory equipment and when used
properly, they provide an accurate and effective means of calibration. Keep the
thermometer in a safe place where it will not be crushed or otherwise broken. When using
the thermometer be careful not to drop or bend the glass. Place a hot thermometer onto
cotton patches to cool. Never put a hot thermometer in contact with cold metal or cold
solvent, the thermal shock can crack or shatter the glass. Mercury is extremely toxic and
should be handled accordingly.
A material safety data sheet (MSDS) for mercury (Hg) can be found in the appendix.
Observe all local, state and federal hazards waste disposal laws when disposing of any
broken thermometers. You can find the names of mercury spill kit suppliers in the
appendix under support vendors. If packaged in a sealed plastic container and labeled with
