That's the question OSHA chief John Henshaw posed at the annual meeting of the Voluntary Protection Program Participants Association in Orlando, Fla., Sept. 9-12.

OSHA's Voluntary Protection Program has grown impressively over 20 years, from a mere three sites in 1982 to more than 850 today in federal and state OSHA programs. But, said Henshaw, VPP sites only represent about one out of every 10,000 companies in America.
