I have spoken with both OSHA and with NIOSH and they have not offered ANY such empirical information...having referred me to the BLS website where a search turned up NOTHING useful related to powered industrial truck operator training and its affect on injuries. So, if theNational Safety Council has an article that addresses my question, I'd like to know how to get the reprint. If you have the author's contact information, that would be most helpful, too. Thank you for your help.
