Operator Protection Overview
The majority of hazards for operating materials testing systems are associated with:
• rapid movement of the crosshead causing crush injuries
• rapid closing of pneumatic grips causing pinch injuries
Operator Protection in Bluehill
®
provides a mechanism that lets you limit crosshead jog
speed and reduce grip closing pressure while you are setting up a test.
The default conditions during test set up are:
• crosshead jog speed reduced to a maximum of 600 mm/min, and can be set lower
if your risk assessment requires it
• grip closing pressure reduced to a default of 15 psi, and can be set lower if your risk
assessment requires it.
