Be sure to properly set up traffic zones and controls when working on streets. Additional regulatory requirements may apply especially if digging up a state owned highway. Collapse of trenches can cause serious injury or death, be sure to utilize proper techniques for trenching and shoring when you are digging. Locate all underground utilities before you start to dig. The PA One Call System notifies all utilities of any excavation work to be performed enabling them to locate and mark their utility lines.
Chemical hazards are also present at wastewater treatment facilities.
Be sure to read and understand the MSDS for the chemical product you are working with. The MSDS for all products should be easily accessible to both system workers and emergency responders. Be sure to follow all recommendations for personal protective equipment when working with chemical products. Clean up all chemical spills promptly. Depending on the type and quantity of chemical spilled, you may also need to report the spill to your county Emergency Operations Center.
