The GHS consists of several key elements, including hazard classification, standardized label elements, and safety data sheets. Hazard classification involves evaluating the hazardous properties of chemicals, such as toxicity, physical hazards, and environmental hazards. Standardized label elements include symbols (pictograms), signal words, hazard statements, and precautionary statements. Safety data sheets provide detailed information about the chemical, including its properties, hazards, protective measures, and safety precautions.
