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, etc. These present serious crush points or pinch points.
