The Occupational Safety and Health Administration’s (OSHA) revised Hazard Communication Standard (HCS) compliance deadline of Monday, June 1, 2015, is fast approaching. The revised standard was effective in 2012, but it has staggered compliance deadlines for various aspects of the regulations over the years. Employers were required to train their employees on the new labeling elements as well as the new standardized safety data sheets by Dec. 1, 2013. The deadline for chemical manufacturers, importers and distributors to comply with new hazard classifications and the classifications of chemical mixtures on their labels is June 1, 2015. However, distributors may still ship chemicals labeled by manufacturers under the old systems until Dec. 1, 2015. Read more about the revised HCS and its requirements.
