This was compiled to give guidance on the assessment, evaluation and control of occupational exposure to inhalable lithium and its hydride and hydroxide compounds, with an emphasis on recommending a health-based guidance occupational exposure value. Based on international toxicological data, the AIOH believes that worker exposure to lithium and its hydride and hydroxide compounds should be controlled to below 0.02 mg/m3 as a 15-minute STEL value, measured as the inhalable dust fraction. This STEL value should also protect against any irritant effects of lithium carbonate.
