March 16: Study Looked at Repair Work on Running Machines

A new study assessed workers carrying out maintenance or repairs on industrial machines operating in reduced speed and force mode. The researchers found that machines aren’t always designed on the basis of the requirements of the OHS law and that workers who enter hazardous zones don’t always use a hold-to-run control or an inching/jogging advance mode. And although most machine speeds observed in factory settings are equal to or lower than the standards, some maintenance or repair jobs are done at production speeds. So compliance with the OHS requirements is an integral part of the risk assessment and reduction process for tasks where workers have no alternative but to enter the zone when machine parts are in motion.
