Crush Zone Hazards
It is important to stay clear of any potential crush zones when the system is
operating. Know where the crush zones are in your system and protect yourself
and others from those crush zones with appropriate safety devices. The following
paragraphs describe crush zones and precautions to take while working around
crush zones.
Locations
A crush zone exists between the platen and crosshead on load units where the
crosshead and specimen move (both areas are shown).
Precautions
Keep clear of any mechanical linkage that moves within a closed area. If the
linkage should move (when the system starts or due to mechanical failure), very
high forces can be present that could pinch, cut, or crush anything in the path of
linkage movement.
Never allow any part of your body to enter the path of machine movement or to
touch moving machinery, linkages, hoses, cables, specimens, and so forth. These
present serious crush points or pinch points.
