The plaque depicts nude male figure, striding left, bearing torch and palm frond; behind him, rearing Pegasus and disc with SAFETY legend. Around top, ROHM & HAAS SAFETY AWARD; in exergue, AWARDED TO THE EMPLOYEES OF THE / BRIDESBURG PLANT / INTERLPANT SAFETY CONTEST / 1954; signed above exergue at right, RENE CHAMBELLAN SC.
The company was founded in Esslingen, Germany, by Dr. Otto Röhm and Otto Haas in 1907. Haas moved to Philadelphia and began the American side of the business on September 1, 1909, from an office on Front Street, while Otto Röhm remained in Germany to run a company that would eventually become Röhm GmbH. The American side of the business grew rapidly and its annual revenue in 2008 reached almost $9 billion. In 2009, the Dow Chemical Corporation acquired Rohm & Haas, ending its independence.
The plaque was awarded to Rohm & Haas plants that had achieved outstanding results in attaining the company's objectives in industrial safety. Usually, this meant an entire year of operations without an accident that caused the loss of work time due to injury. The plaque depicted is dated 1954 and that is the earliest mention of the award I could find. While I can't know for sure, I would date the plaque to the early 1950's. Any additional information would be appreciated.
The plaque is cast in coppery bronze and measures 273mm x 395mm. No mintage is reported though it was still being awarded in the 1970's, so there must be quite a few of them around.
