What does STEL stand for in the context of chemical exposure limits?

STEL stands for Short Term Exposure Limit, which refers to the maximum concentration of a substance that workers can be exposed to for a short period, typically averaged over a 15-minute interval. This limit is designed to protect workers from acute effects that could occur due to high levels of exposure for brief durations. The Short Term Exposure Limit is crucial in environments where workers might encounter hazardous chemicals, as it helps to minimize the risk of immediate health impacts, such as respiratory distress or other acute health problems. Understanding and adhering to STEL limits is essential for maintaining safety in the workplace when dealing with hazardous materials.
