What type of chemicals require SDSs as mandated by HCS?

The requirement for Safety Data Sheets (SDSs) under the Hazard Communication Standard (HCS) applies to all hazardous chemicals. This includes a wide range of substances that may pose physical or health hazards in the workplace. The HCS defines hazardous chemicals broadly; it encompasses not only toxins but also flammable materials, corrosive agents, and any other chemical that could pose risks such as reactive properties.

The purpose of the SDS is to provide detailed information about the hazards associated with a chemical, as well as safe handling, storage, and emergency measures. By ensuring that SDSs are available for all hazardous chemicals, the HCS aims to promote safer workplaces by giving workers and employers access to critical safety information. This comprehensive approach helps to ensure that individuals are equipped to manage chemical risks in various environments, not just those that pertain to a specific subset of chemicals like toxins or flammable materials.
