Who is responsible for determining if a material is hazardous according to OSHA HAZ Com?

1. The employer

2. The worker

3. The manufacturer or importer

4. The government agency

The correct answer is: The manufacturer or importer

The manufacturer or importer is responsible for determining if a material is hazardous according to OSHA's Hazard Communication (HazCom) Standard. This responsibility stems from the requirement that these entities evaluate the physical and health hazards of the chemicals they produce or import. They must conduct thorough assessments and ensure that safety data sheets (SDS) are created to convey this information effectively to downstream users, including employers and workers. The proper classification of hazards is critical, as it directly influences how these materials must be handled, stored, and used in the workplace. By assigning this responsibility to the manufacturer or importer, OSHA ensures that those who have the most knowledge about the chemical—its properties, usage, and potential dangers—provide accurate information to help protect workers and the environment. While employers also play a significant role in communicating and implementing safety measures, their duty hinges on the information provided by manufacturers or importers. Thus, the primary responsibility for determining a substance's hazardous nature correctly lies with the manufacturer or importer.
