nicor gas
As Illinois’ largest natural gas distributor, and owner and operator of one of the largest natural gas aquifer storage systems in North America, NICOR has added the Prospan PRO-Lite trench shields to its arsenal. With 2,000 employees constructing, operating, maintaining, and inspecting a nearly 34,000-mile distribution system, the safety of their employees is their highest priority. Whether it’s the Prospan air shores or our lightweight trench boxes, compliance has never been easier.
