OCOSH facility closing, moving to Columbus BWCs Ohio Center for Occupational Safety and Health (OCOSH) is moving from Pickerington to downtown Columbus at the end of October. This will not change the way you call or email us. Remote services during the COVID-19 pandemic will continue. However, OCOSHS address will change to the 25th floor of the William Green Building, 30 W. Spring St., Columbus, OH 43215.OCOSH houses our Division of Safety & Hygiene. Were bringing the center to our headquarters to foster greater collaboration with our other divisions, fill the available space we have in the William Green Building, and save on costs, all of which leads to better service for our customers.
