Here are the existing short-term exposure guidelines: National Research Council [NRC 1984] Emergency Exposure Guidance Levels (EEGLs):
10-minute EEGL: 30 ppm
30-minute EEGL: 20 ppm
60-minute EEGL: 10 ppm
24-hour EEGL: 5 ppm
Ass you can see lethal exposure is time and concentration dependent.
“Ass you can see lethal exposure is time and concentration dependent.”

Guess I’m lucky from my exposure as a youth. Will never forget the smell.
Mining, yes I own gold mines on 2 separate properties but they’re in California so are inactive.
