• Use protective gear (such as gloves) if it is necessary to handle hot objects. Hot objects can include
specimens tested at elevated temperatures or furnace surfaces.
• When using an environmental chamber or furnace, be aware of possible crush points between the grip
and any attachment fixture and the chamber or furnace.
Hazard Placard Placement
Hazard placards contain specific safety information and are affixed directly to the system so they are plainly
visible.
Each placard describes a system-related hazard. When possible, international symbols (icons) are used to
graphically indicate the type of hazard and the placard label indicates its severity. In some instances, the
placard may contain text that describes the hazard, the potential result if the hazard is ignored, and general
instructions about how to avoid the hazard.
The following labels are typically located on the grips.
Part # 47-081-201
Part # 47-469-701
Each label contains the following information:
• Model number
• Part number
• Serial number
• Revision level
• Temperature range
• Force capacity
• Maximum pressure
Note:
The two versions of this label have different pressure and force ratings.
