Hydrogen Safety 
March 5, 2016

When a metal is corroded by sulphuric acid one of the products formed is hydrogen gas.

M + H2SO4 -> MSO4 + H2

When corrosion is rapid and severe a large quantity of hydrogen gas can accumulate in the equipment and quickly reach the lower explosive limit.  The amount of energy required to ignite the gas mixture is small and the result is an explosion that will damage equipment.

The sulphuric acid industry has recognized this hazard and have collaborated to investigate these incidents and bring the hazards of hydrogen explosion to the attention of the industry.  Many papers have been published and presented at conferences to ensure that all operating companies are aware of the issue.
