What is the Threshold Limit Value Ceiling (TLV-C) designed to protect against?

  1. Long-term exposure risks

  2. Short bursts of high concentration exposure

  3. Continuous low concentration exposure

  4. Overall environmental safety

The correct answer is: Short bursts of high concentration exposure

The Threshold Limit Value Ceiling (TLV-C) is designed to protect individuals from short bursts of high concentration exposure to hazardous substances. This value indicates the maximum concentration of a chemical in the air that workers can be exposed to at any time, without experiencing adverse health effects. TLV-C values are particularly important for substances that can cause immediate health issues if inhaled or absorbed in large amounts over a short period. In contrast, long-term exposure risks, continuous low concentration exposure, and overall environmental safety are addressed through different exposure limits and standards, such as time-weighted averages (TWAs) or other regulatory guidelines. These are aimed at protecting workers from chronic health effects associated with prolonged exposure to lower concentrations of toxic substances. However, the TLV-C is explicitly set for scenarios where high concentrations may occur briefly, emphasizing the importance of adhering to it to prevent acute toxicity.
