The Hazard Communication Standard refers to a set of regulations put in place to reduce the risks associated with hazardous materials in the workplace. There are several synonyms for this term, including the Right-to-Know Law, Workplace Hazard Communication, and Material Safety Data Sheets (MSDS). Each of these terms is intended to communicate the same basic idea: that employers have a responsibility to inform their employees about the hazards of the materials they work with, and to provide them with the necessary tools and training to be safe. Whether in a chemical plant or a coffee shop, the Hazard Communication Standard is an essential part of ensuring the health and safety of workers.
