What is the meaning of the acronym TLV?

The acronym TLV stands for Threshold Limit Value. This term is widely used in occupational safety and health contexts to denote the maximum concentration of a substance in the air that a worker can be exposed to without experiencing adverse health effects. TLVs are developed by organizations such as the American Conference of Governmental and Industrial Hygienists (ACGIH) and are critical for establishing safety standards in workplaces where hazardous substances are handled.

By setting these values, TLVs help in assessing risk and implementing appropriate safety measures, including ventilation, personal protective equipment, and other engineering controls to ensure worker safety. This makes it essential for those working in environments where exposure to chemicals occurs, such as tankerman assistants in the marine industry, to be familiar with TLVs for safe operation and handling of materials.
