An El Paso Water employee died from the toxic effects of hydrogen sulfide, or sewer gas, and possible drowning, according to findings from an autopsy done by an El Paso County medical examiner.
The hydrogen sulfide gas is biochemically oxidized in the presence of moisture to form sulfuric acid. The effect of sulfuric acid on concrete and steel surfaces exposed to severe wastewater environments can be devastating. [1] In the USA alone, corrosion causes sewer asset losses estimated at $14 billion per year. [2]
Chronic exposure to hydrogen sulfide can cause several long term health issues, though H 2 S does not accumulate in the body. [ 11 ] Repeated or prolonged exposures have been reported to cause low blood pressure, headache, loss of appetite, chronic cough, inflammation of the eye membrane, weight loss and ataxia.
The researchers also determined that people who use their stoves at home 110 days a year had exposure to nitrogen dioxide that exceeds the World Health Organization’s recommended 200 µg/m3 for ...
JE Webb addressed a number of problems with the lamps with further patents. His patent GB189408193, [2] approved 2 March 1895, stated: It has also been found that when the gases are drawn out from the sewer by the burning of ordinary gas a sudden flushing of the sewer might prevent any sewer gas from escaping, and thus momentarily cause the gas jets to be extinguished.
The sewer overflow was reported to the City of Bellingham Public Works after-hours line on Saturday afternoon, according to Public Works’ Communications and Outreach Manager Riley Grant.
