Hazard Communications
A standard set of rules were developed by OSHA to facilitate workplace chemical safety. The HazCom Standard (HCS) ensures workers are provided with information about the chemical hazards in their workplace. Chemical suppliers are required to evaluate the hazards of their chemicals and supply Material Safety Data Sheets (MSDSs) to communicate those hazards. It requires that all hazardous chemicals be labeled and that the MSDS sheets are readily available to all exposed workers. The MSDS sheets are located in the Grice Conference Room (Room 106). It also requires that employers train their workers in HCS and how to safely handle chemicals.
