INTRODUCTION

H2S (Hydrogen Sulphide) is a gas that can be created by natural biological processes 

or by human activity and poses a serious threat to people or assets because of its 

extremely toxic and corrosive properties. It is important, therefore, for all personnel 

working in construction industry, sewage and water treatment plants, and oil & gas 

facilities to be competent in emergency response training. In addition become aware of 

the necessary practices to stay and work in an environment with potential exposure to 

H2S gas. This training will cover the characteristics of Hydrogen Sulphide gas and the 

potential physiological effects of exposure as well as the use of H2S detection equipment 

and escape breathing apparatus.
