What is the STEL (short-term exposure limit) for hydrogen sulfide, and how does it differ from the TWA (time-weighted average) exposure limit?

The short-term exposure limit (STEL) for hydrogen sulfide is 10 parts per million (ppm) for a 15-minute period, according to OSHA. The time-weighted average (TWA) exposure limit for hydrogen sulfide is 1 ppm for an 8-hour workday. The STEL represents a concentration that should not be exceeded during any 15-minute period, while the TWA represents the average exposure over an 8-hour period. Hydrogen sulfide is a highly toxic gas that can cause respiratory irritation, loss of consciousness, and even death at high concentrations. Employers should implement controls to minimize hydrogen sulfide exposure and ensure that workers' exposure levels are below both the STEL and TWA limits.
