Who is responsible for classifying chemicals under the HCS?

The correct response highlights that both employers and chemical manufacturers/importers share the responsibility for classifying chemicals under the Hazard Communication Standard (HCS). This dual responsibility ensures that all chemicals presented in the workplace are properly assessed for hazards, allowing for accurate communication of that information.

Chemical manufacturers and importers must classify the hazards of the chemicals they produce or import. They are responsible for conducting the necessary assessments to determine the potential risks associated with each chemical, including evaluating its physical and health hazards. Once classification is complete, they must provide labels and Safety Data Sheets (SDS) with detailed hazard information.

Employers, on the other hand, have the duty to ensure that the chemicals used in their workplaces are appropriately labeled and that employees have access to information regarding the potential hazards. This involves training workers on how to interpret labels and SDS, as well as implementing proper safety measures based on the classifications provided by the manufacturers.

This co-responsibility enhances workplace safety, as it ensures that all parties are aware of chemical hazards and can take appropriate actions to protect employees from those hazards.
