Who must determine hazards of chemicals produced or imported?

• A. Chemical manufacturers and importers
• B. Government inspectors
• C. Employees
• D. Safety committees

Answer: (A)

The essential idea is that the supplier of a chemical is responsible for evaluating and classifying its hazards. Under OSHA’s Hazard Communication Standard, chemical manufacturers and importers must determine the hazards of the chemicals they produce or bring into use and communicate that information to downstream users through labels and Safety Data Sheets. They gather or generate data on physical hazards (like flammability), health hazards (such as toxicity), and environmental hazards, using testing data or recognized classification methods. This makes sure workers and employers have clear, consistent information to handle and store the chemical safely. Government inspectors enforce compliance and verify the information is provided, but they don’t determine the hazards for each product. Employees and safety committees rely on the supplier’s hazard information to protect themselves, but the initial hazard determination rests with the chemical manufacturers and importers.
