It’s hard to find safety lessons that are ready mixed concrete-specific, self-directed, measure individual retention and include an automatic proof-of-training for your compliance records. That is until June 1, when NRMCA launched its 20- 25 minute lessons on its safety e-learning Web site. Available 24/7 from any computer, the first two lessons cover backing accident prevention for both rear and front discharge mixers. Watch the lessons’ preview clip and take advantage of the special introductory price during June.
