1 Facilities Management Plicy Number: Title: Chemical Hygiene Plan Implementatin Date: 2002 Last Audit: May, 2018 Last Revised: June 20 th, 2018 Intrductin The U.S. Department f Labr and the Occupatinal Safety and Health Administratin (OSHA) prmulgated the final rule (29 CFR ) titled Occupatinal Expsures t Hazardus Chemicals in Labratries n 31 January Tennessee Occupatinal Safety and Health Administratin fficials have adpted this standard verbatim. This new standard differs frm many OSHA health standards in that it des nt establish new expsure limits, but sets perfrmance prvisins designed t prtect labratry wrkers frm ptential hazards in their wrk envirnment. Purpse The primary purpse f the East Tennessee State University Chemical Hygiene Plan (CHP) is t prtect emplyees and t reduce the risk f injury frm chemical hazards assciated with particular labratries. This is accmplished by establishing respnsibilities, plicies and prcedures fr handling hazardus chemicals and thrugh the develpment and implementatin f wrk practices and cntrl measures expressly tailred t the varius labratries present at the University. Additinally this plan serves as a guide fr the varius University Divisins as they develp their specific Chemical Hygiene Plans. Definitins Chemical Hygiene Officer - The designated emplyee wh is qualified by training r experience t prvide technical guidance in the develpment and implementatin f the Chemical Hygiene Plan. Chemical Hygiene Plan - A written prgram which sets frth plicy and prcedures t prtect emplyees frm the health hazards assciated with their wrk place. Plicy Number Chemical Hygiene Plan Page 1 f 9
