| These values are approximate and vary as to the individual’s state of health and his physical activities. Although the foul odor (rotten eggs) of hydrogen sulfide is easily detected at low concentrations, it is an unreliable warning because the gas rapidly desensitizes the olfactory (sense of smell) nerves and leads to a false sense of security. In high concentrations of hydrogen sulfide, a worker may collapse with little or no warning. *PPM – Parts Per Million – volume measurement of gas concentration. |
