CALCIUM CHLORIDE WHITE PAPER Optimize Your Sidewalk Ice Melting Program to Improve Winter Safety and Meet the Challenges of Today’s Business Climate By Greg MacDonnell General Manager Occidental Chemical Corporation (OxyChem) Preventing winter slip and fall accidents Floor Safety Institute, the average cost reputations among visitors who can tell has never been more important for of a worker compensation claim for a that owners and managers – and by building owners, facility managers and slip and fall accident is $4,000.
