Concentration of a highly hazardous mixture refers to the level of hazardous components in a mixture that is used to assess its potential risks to human health and the environment.
When the concentration of highly hazardous components exceeds specified regulatory thresholds, the mixture may be subject to stricter classification, labelling, packaging, and risk management requirements.
These concentration limits are particularly important for mixtures with acute or chronic toxic effects, where they help determine the appropriate hazard classification and safety measures.
