Safety and Health Administration's (OSHA's) Hazard Communication Standard (HCS) is
based on a simple concept - that employees have both a need and a right to know the
hazards and identities of the chemicals they are exposed to when working. They also need
to know what protective measures are available to prevent adverse effects from occurring.
The HCS is designed to provide employees with the information they need.
Knowledge acquired under the HCS will help employers provide safer workplaces for their employees. When employers have information about the chemicals being used, they can take steps to reduce exposures, substitute less hazardous materials, and establish proper work practices. These efforts will help prevent the occurrence of work-related illnesses and injuries caused by chemicals.
