Their culture of innovation - along with their commitment to all of their core values - drives us to constantly strive for new and better ways of serving their customers. USG has been committed to the safety of their employees, customers and the general public since 1902. They have developed and adhered to safety guidelines that exceed industry standards and regulations. In fact, 12 of their 34 U.S. manufacturing locations and three of their L&W Supply distribution facilities have applied and qualified for OSHA VPP Star status. To attain the Star designation, employees, management and OSHA work together to implement safety and health programs and processes that go beyond OSHA regulations to further protect employees and promote safe operations. Fewer than 2,500 worksites of the more than eight million in the U.S. have received the VPP Star designation. This "safety first" culture is what keeps their facilities more productive and it's why their employees are able to go home after every shift to see their families - many of whom work at USG for multiple generations.
