H2S GAS PROPERTIES AND SOURCES

H2S GAS 

H2S gas is the invisible killer gas,and it is

• Toxic
• Highly flammable, and Corrosive

Its smell like rotten eggs. H2S is mostly found in

1. Coal pits
2. Sulfur springs
3. Gas wells.
4. Sewers,
5. Sewage treatment plants

H2S is found in

• Petroleum and natural gas extraction and refining,
• Paper and Pulp manufacturing,
• Rayon textile Production,
• Leather Tanning,
• Chemical manufacturing and 
• Waste disposal.

Others names for Hydrogen Sulphide

• H2S
• SOUR GAS
• STINK DAMP
• ROTTEN EGG GAS
• HYDROSULPHURIC ACID
• SULPHUR HYDRIDE
• SEWER GAS
• SULPHURATED HYDROGEN

PHYSICAL AND CHEMICAL PROPERTIES

• COLORLESS
• HEAVIER THAN AIR
• CORROSIVE
• HIGHLY FLAMMABLE ( EXPLOSIVE )
• SOLUBLE IN WATER
• SMELL LIKE ROTTEN EGGS
• IRRITANT
• EXTREMELY TOXIC

HYDROGEN SULPHIDE HAS A DENSITY GREATER THAN AIR

• H2S DENSITY : 1.19
• AIR DENSITY :  1.0

THIS IS IMPORTANT TO REMEMBER IT IS FOUND IN LOW LYING AREAS SO THIS INVISIBLE GAS WILL COLLECT IN

• DEPRESSIONS IN THE GROUND
• PITS
• DITCHES
• TRENCHES
• CONFINED SPACES
