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
The crush zones exist between the test table and lower crosshead, and the lower
crosshead and upper 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.
Fixture mounting
