Permissible exposure limits (PEL) are the maximum allowable concentrations of hazardous substances in the workplace.
H2S: PEL is 10 ppm (parts per million) over an 8-hour workday
CO: PEL is 50 ppm over an 8-hour workday
CO2: No specific PEL, but recommended exposure limit is 5,000 ppm over an 8-hour workday
Methane: No specific PEL, but recommended exposure limit is 1,000 ppm over an 8-hour workday
Short term exposure limit (STEL) of H2S is 10 ppm.
STEL is the maximum concentration of a substance that a worker can be exposed to for a short period of time without suffering from immediate or long-term health effects.
The STEL for H2S is set at 10 ppm (parts per million) by OSHA (Occupational Safety and Health Administration).
Exposure to H2S at levels above the STEL can cause symptoms such as eye irritation, headache,...
