ResumoOccupational exposure limits (OELs) are useful for health professionals to identify toxic substances and their toxic risk in case of human exposure. The value of an OEL depends on the outcome of the risk assessment and the risk management processes for a substance. The common OEL duration categories include mean OEL, time-weighted average (TWA), threshold limit value (TLV), TLV-TWA, short-term exposure limit, ceiling limit, derived no effect levels. Most published OELs are derived from adverse effects arising from occupational exposure to contaminant concentrations in the air. Skin-penetrating compounds may exert systematic toxic effects. Assessing exposure to physical agents is important for protecting worker health.
