What does TLV-TWA stand for?

TLV-TWA stands for Threshold Limit Value-Time Weighted Average. This term is crucial in occupational health and safety as it represents a concentration of a substance in the air that workers can be exposed to over a typical 8-hour workday and 40-hour workweek without experiencing harmful effects.

The "Threshold Limit Value" indicates the maximum allowable level of exposure, while "Time Weighted Average" means that this exposure is measured over time, accounting for variations in concentration throughout the work shift. This average gives a more accurate picture of a worker's exposure and helps ensure their safety and health in the workplace.

Understanding TLV-TWA is important for compliance with safety regulations and for implementing appropriate controls to minimize risks related to hazardous substances.
