GHS classifies chemicals into different categories based on the type and severity of the hazard. This involves a thorough assessment of available data on the chemical's properties and its potential effects on health and the environment. The classification process considers various endpoints, such as:
- Acute toxicity: Evaluates the adverse effects that result from a single or short-term exposure. - Skin corrosion/irritation: Assesses the potential for chemicals to cause damage to the skin. - Carcinogenicity: Determines the likelihood of a chemical causing cancer. - Reproductive toxicity: Examines the impact on sexual function and fertility.
Each hazard class is further divided into categories, which reflect the severity of the hazard. These categories aid in determining the appropriate hazard communication elements, such as pictograms, signal words, and hazard statements.
