I REFER to The Star report, “Two Indian nationals die after inhaling poisonous gas in Cyberjaya”, published on Aug 21 (online at bit.ly/star_poison). The two workers died while installing cables in a manhole.
Fatal accidents from working in confined spaces are often reported in the media. The cause of such deaths is often the presence of hazardous gases in a confined space where ventilation is inadequate. Among the common gases are methane, hydrogen sulphide and carbon dioxide, sometimes oxygen deficiency is also one of the causes. The presence of hazardous gases in confined spaces is mainly due to the decay of organic wastes seeping into the space.
