What Is The Idlh For Hydrogen Sulfide
Hydrogen sulfide's immediate life-threatening and health concentration (IDLH) refers to the concentration at which it is immediately life-threatening or has irreversible or delayed effects on health. Hydrogen sulfide is highly toxic, and its IDLH concentration is usually set at 100 ppm. In this concentration environment, people may suffer serious health damage or even life-threatening short-term exposure.
If the human body is exposed to hydrogen sulfide at or above this IDLH concentration, it will quickly develop serious symptoms such as breathing difficulties, confusion, convulsions, etc. Because it can quickly paralyze the olfactory nerve, people will lose the perception of its odor for a short time. Even if the smell of rotten eggs can be smelled at the beginning, as the exposure time increases and the concentration increases, the olfactory perception will weaken, increasing the potential danger.
When operating in sites where hydrogen sulfide may be present, the concentration of hydrogen sulfide must be strictly monitored to ensure that it is well below the IDLH value, and effective personal protective equipment, such as self-contained respirators, must be provided to the operator to ensure the safety and health of personnel.
