Machine Stop Time Measurement â Did You Know? Current OSHA regulations and ANSI standards requires that a machine's stop time be measured to determine how long it takes a machine to stop after a stop signal is given. (OSHA 1910.217, ANSI B11.19-2010 (6.2). Most accidents occur as a result of a reflex action or simply not paying attenti on to one's surroundings. Often a machine operator will instinctively reach for something when there is a problem. Or they will be focused on a task and enter a hazardous area without thinking about it. Tripping towards a hazard is another common occurrence. In these situations, it is necessary that the machine's safet y devices stop the machine before the hazard is reached. Stop-time measurement readings taken on individual machines are used to determin e the minimum safety distance required for placement of the machine's operating controls or safeguarding devices used during production. This is critical when u sing presence sensing devices like light curtains, pressure mats, laser scanners , etc. Location of a safety component, whether hard guarding or electronic, is based up on the machine's stopping time. Simply stated, a safety component should be plac ed far enough away from the risk area that it is not possible to reach the hazar d before the machine has stopped. Safety devices are then installed using the mi nimum safe distance. See OSHA Safety Distance Calculator. Stop time measurement should be performed on an annual basis in order to insure that the machine stop time has not changed. Machine maintenance, brake wear, mac hine alterations and other factors can extend the machine's stopping time. If th e machine stops slower than it once did, then the current safety components will need to be adjusted to continue providing the correct level of safety. For thes e and other reasons it is important to perform an annual stop time analysis. Not sure how to get started? Lovegreen can provide stop-time measurement reading s for various types of industrial machines, including mechanical and hydraulic p ower presses, press brakes and on machines that utilize rotational movement like conveyors, indexing tables, and production line drive shafts. Experienced Loveg reen personnel conduct the inspections using a stop-time measurement device to t ake the stop-time readings. Lovegreen uses the same stop time analysis Saftimete r as OSHA to assure consistent results. Inspections include details on each machine as to its compliance to current safe ty regulations (OSHA) and current safety standards (ANSI). Stop-time measurement readings taken on individual machines are used to help determine the minimum sa fety distance required for placement of the machineâs operating controls or safeguar ding devices used during production operations, such as safety blocks and die bl ocks.
