The Hanford Building Trades' Communication Center If you are eligible for the Hanford Building Trades Medical Screening Program and want further information, please use our e-mail page to contact us. Be sure to include your area code, telephone number, and the best time to call. Additionally, we welcome any and all comments and encourage you to come back often to see our continual improvements. Our site serves as an important educational and public resource. Because of this diverse user group, we have designed our new communication center to facilitate direct inquiry for users of our site.
