What are hazard categories?

Hazard categories refer to classifications that indicate the degree of severity of hazards associated with chemicals. These categories help in identifying and assessing the potential risks posed by chemical substances. For instance, a material may be categorized based on its toxicity, flammability, or chronic health effects. By using these classifications, safety data sheets (SDS) and labels can communicate the necessary precautions and protective measures that need to be taken when handling the substance. This systematic approach enables workers to understand the risks and to implement appropriate safety measures effectively when working with hazardous materials.

The other options do not accurately describe what hazard categories entail. Indications of safe handling procedures relate more to practical steps to ensure safety rather than classification of hazards. Procedures for chemical waste disposal are focused on the management of hazardous waste rather than the identification of hazard levels. Types of protective equipment required pertain to personal safety measures rather than the categorization of the hazards themselves.
