Utilities like this wallet card because it's a safety reminder that contractors can keep with them on the job site, as well as a phone number reference to call the utility and 911 in the event of a utility contact. Consider giving out wallet cards at the end of your safety presentation or tailgate meeting with contractors, or mail them out. Also available: Worker Beware Power Line Safety Wallet Card (#86310), and customized versions such as a combined overhead and underground.
