MUST sponsors on-line safety training through Pure Safety. Eighteen safety awareness modules must be completed by each craft working on MUST job sites. The modules expire and must be retaken every four years. After completion of MUST Safety Modules or hands-on safety training, an on-line report card, showing all completed training can be found for each user. Access to report cards is available to construction users and contractors. Safety-trained men and women are also reminded on their report cards, when to update their training.
