Safety Summary
The following are recommended safety precautions unrelated to any specific procedures in this manual and there-
fore do not appear elsewhere. Personnel must understand and apply them as appropriate during all phases of
operation and maintenance. IN ALL CASES, BE PRUDENT.
Keep Away From Live Circuits
Do not replace components or make adjustments inside equipment with power turned on. To avoid
injuries, always remove power source and discharge and ground a circuit before touching it. When
making electrical connections, the services of a qualified electrician must be employed. Contact with
live electrical circuits can cause serious personal injury or death. Be sure no circuits are energized
during installation, connection or removal of any electrical cables or lines.
Wear Protective Clothing
Wear protective clothing (gloves, apron, goggles, etc.) approved for the materials and
tools being used.
Provide Adequate Ventilation
Provide ventilation to remove heat and noxious odors and to prevent the accumulation of
asphyxiates such as nitrogen gas.
Avoid Hot Surfaces
Keep hands away from hot surfaces and materials. Contact with hot surfaces or materials can cause
blistering and third-degree burns. Wear approved, clean, thermally insulated gloves when handling
these components. Should injury occur; immerse injured area in cold water and get immediate
medical attention.
Use Gloves--It’s Very HOT!
To prevent burns, gloves and a long sleeve shirt (or lab coat) are essential. Dies and piston rods are
extremely hot and are designed to quickly transfer heat to the sample being tested. Unfortunately,
this means they will transfer heat very quickly to you as well. Even brief contact with a hot item can
cause a burn. The indexer barrel housing can also get very hot. However, at any barrel temperature,
these should not cause burns if touched for a very brief period except very near the barrel top and
bottom. Consider where dies may fall. If they are dropped on nylon carpeting or similar materials,
they can quickly form holes. Protective mats may be needed.
DYNISCO POLYMER TEST recommends keeping hot piston rod and hot die in the chamber/barrel;
this precludes someone picking it up inadvertently. Be sure to hold the piston by the top insulator.
Electrical Hazard
Your Dynisco Lab Melt Flow Indexer contains high voltage inside the housing. DO NOT remove the
housing or any part of its outer covers; there are no user serviceable parts inside. Service should
only be done by a qualified DYNISCO Service Technician. Be sure the outlet used to power the
indexer is properly grounded.
