Effects of Carbon Monoxide (CO) on Human Body

Effects of Hydrogen Sulfide (H2S) on Human Body

Methane gas generate an explosive gas in air. Explosive Range = 5.0% ~ 15.0%

Iso-Butane generate an explosive gas in air. Explosive Range = 1.8% ~ 8.4%

Human body react to Oxygen-Deficiency is rapid breathing, headache, nausea, ear ringing...

Ballast tanks take in and expel water to maintain a ship's balance. The steel plating on the walls inside become oxidized with surprising speed.

Manholes, stormwater pits and raw water tanks at sewage treatment plants can easily cause oxygen deficiency and hydrogen sulfide (H2S) poisoning from decomposing organic matter.

Sediment in sewers contain many kinds of components such as sulfuric acid and sodium sulfide from treatment plants as well as amino acids from food processing plants.

The incinerator ash contains sulfides produced when the sulfurous compounds inside garbage are incinerated.
