Understanding TLV: The Threshold Limit Value for Workplace Safety

TLV stands for "Threshold Limit Value". It is a measure of the maximum amount of a substance that can be present in the air before it becomes hazardous to human health. The TLV is usually expressed as a concentration of the substance in parts per million (ppm) or milligrams per cubic meter (mg/m3).

For example, the TLV for a certain chemical may be 100 ppm, which means that if the concentration of that chemical in the air exceeds 100 ppm, it can cause adverse health effects. The TLV is used as a guideline by occupational safety and health professionals to determine safe exposure levels for workers in various industries.
