More than two-thirds of the data generated by sensors that measure inertial loads during materials handling were deemed to be acceptable by researchers at , a Quebec-based research organization, according to a summary published on the IRSST . The results indicate progress toward the researchers’ goal of demonstrating the effectiveness of materials-handling principles in occupational settings. During trials, the sensors accurately estimated 68 percent of the inertial stresses on workers. Previous attempts were less successful because the sensors proved susceptible to magnetic disturbances that skewed their data. The current study indicates that disturbances are still a problem. Still, the IRSST researchers were encouraged by the results. “At first, simply passing a pair of scissors in front of the sensors produced a great deal of disturbance,” said IRSST’s Andre Plamondon. “Happily, this is no longer the case today.”
