How to Deal With Hydrogen Sulphide Gas

Hydrogen Sulphide (H2S) is known as the "silent killer". It's an insidious and invisible gas that smells a bit like rotten eggs at low concentrations. It quickly paralyzes the olfactory nerves (sense of smell) at about 100 parts per million (ppm). Many times, upon an investigation of major incidents/fatalities, the concentration didn't go from zero to toxic but simply hit the victim with a deadly concentration immediately. Confronted with increasing legal and social pressures, no tanner can afford the luxury of not being familiar with the main issues and principles of occupational, safety, and health protection pertaining to tannery operations. Hydrogen sulphide gas present in tanneries and effluent treatment plants has proven fatal to workers exposed to it many times. It is, therefore, necessary that the owners and managers of tanneries and effluent treatment plants are fully aware of the dangers posed by this poisonous gas and take all preventive and precautionary measures to protect the workforce from exposure to this gas. In the event of accidental exposure of a worker, they should know how to deal with the situation. The lessons that follow are to help tanners, tannery managers, and operators to acquaint themselves with the basic principles of how to deal with hydrogen sulphide gas.
