The TLV-STEL (Threshold Limit Value-Short-Term Exposure Limit) corresponds to which exposure duration?

Explanation:
TLV-STEL is the maximum concentration a worker can be exposed to for a short period without acute health effects. That short period is defined as 15 minutes. This is different from TLV-TWA, which applies to an 8-hour workday (or 40-hour week) average. So the 15-minute duration is the correct answer for the STEL.
