- H2S is a colourless, flammable, toxic, and corrosive gas which is heavier than air.
- Both black and clean cargoes may contain it.
- It is found naturally in crude petroleum, natural gas, and hot springs. It is generated from decomposing organic materials.
- Only reliable method of determining the gas concentration is by testing it with the proper instruments.
- It can be smelled at low levels (smells like rotten eggs), but with continuous low-level exposure or at higher concentrations, you lose your ability to smell it even though it is still present. At high concentrations ability to smell the gas can be lost instantly.
These are the properties of H2S and it is the most dangerous and deadly gas that is found in the crude oil, oil products, and natural gas. Extra safety procedures to be followed when carrying cargoes with high H2S content. Check out our Learning Engagement Tool CBT trailer for “H2S Exposure” which is an interactive training, prepared with problem-based learning methodology, based on scenarios and triggering discussion questions.
