 CONT: Darryl says that office safety training takes place once a  year, or after an accident, and that "weve never made it a full  year". However, in the episode "Boys and Girls", Mag, the female  dockworker, had erased the number 934 from a chalkboard, that had  said "Weve gone 934 days without a lost time accident". 934 days is  over 2.5 years. "Boys and Girls" takes place only about one year  before "Safety Training"
