The method makes use of the toxic nature of the gas hydrogen sulfide (H2
S) and it’s ease of generation from readily available
(unrestricted) household chemicals. Hydrogen Sulfide (commonly known as ‘rotten egg gas’) is extremely toxic when inhaled.
The mechanism of action is similar to that of hydrogen cyanide where the gas binds with and destroys the function of mitochondria within living cells. The gas is as toxic as hydrogen cyanide, but accidental exposure is uncommon because of the strong and unpleasant smell noted with even the smallest concentrations of the gas.
Concentrations of over 0.1% (1000ppm) will lead to immediate loss of consciousness and rapid death. Production of the gas in a confined space (with levels in excess of 1%) will cause certain death.
