The basic goal of the Hazard Communication Standard is to be sure employers and employees know about work hazards and how to protect themselves, thereby reducing the incidence of chemical source illness and injuries. The standard establishes uniform requirements to make sure that the hazards of all chemicals imported into, produced, or used in United States workplaces are evaluated, and that this hazard information is transmitted to affected employers and exposed employees. The producers of chemicals have the primary responsibility for generating and disseminating information, whereas users of chemicals must obtain the information and transmit it to their own employees. The chemical manufacturers/importers determine the hazards of each product, and communicate the hazard information and associated protective measures to customers through labels and material safety data sheets (MSDSs). Employers identify and list hazardous chemicals in their workplaces; develop and implement a written hazard communication program; and communicate hazard information to their employees through labels, MSDSs, and formal training programs. The MSDS is a detailed information bulletin prepared by the manufacturer or importer of a chemical that describes the physical and chemical properties, physical and health hazards, routes of exposure, precautions for safe handling and use, emergency and first-aid procedures, and control measures. OSHA offers a variety of programs and initiatives to help employers comply with the agency’s standards or guidelines, such as consultation services and training and education.
