What does TLV-STEL stand for?

The term TLV-STEL stands for Threshold Limit Value – Short Term Exposure Limit. This concept is used to define the maximum concentration of a hazardous substance that workers can be exposed to for a short duration, typically 15 minutes, without experiencing harmful effects. This limit is important because it helps ensure that workers are protected from potential acute health effects that could occur from brief periods of intense exposure to certain chemicals or hazardous materials.

In occupational safety and health, the TLV-STEL is particularly relevant for substances that may cause immediate or acute health issues when exposure occurs at high levels, even for short durations. Understanding this concept allows safety professionals and incident commanders to assess and manage risks in environments where hazardous materials are present.

The other options do not accurately represent the established terminology or do not correspond to accepted safety concepts in occupational health.
