What does TLV-TWA stand for?

• A. Threshold Limit Value - Time Weighted Average
• B. Threshold Level Value - Time Weighted Average
• C. Time Limit Value - Total Working Average
• D. Time Limit Ventilation - Weighted Average

Answer: (A)

The correct answer is Threshold Limit Value - Time Weighted Average. TLV-TWA is an important concept in occupational health and safety that refers to the maximum concentration of a hazardous substance in the workplace to which a worker can be exposed over a typical 8-hour workday or 40-hour work week without adverse health effects. This standard is set by organizations such as the American Conference of Governmental and Industrial Hygienists (ACGIH) and is used as a guideline for evaluating and controlling exposure to chemicals and other hazardous substances in the workplace. The "Time Weighted Average" aspect indicates that this value takes into account fluctuations in exposure throughout a work shift, rather than a single maximum exposure point. Recognizing the correct terminology and understanding its implications is critical for maintaining compliance with safety regulations and ensuring a safe working environment. In contrast, the other options use incorrect terminology or misrepresent the concept, which would lead to confusion about the standards for workplace exposure and its management.
