Four Workers Dead in Japan After Manhole Fall
Four workers have died in Japan after falling into a manhole near Tokyo as they inspected sewage pipes, authorities said Sunday. The incident comes after a huge sinkhole swallowed a truck driver near the capital in January after a road collapsed because of corroded sewage pipes, sparking a nationwide inspection. The workers -- all men in their fifties -- were checking pipes in the city of Gyoda north of Tokyo on Saturday when one fell down the manhole, followed by three more who tried to save him, the local fire department told AFP. The department said rescuers detected hydrogen sulfide -- a gas toxic in high concentrations -- coming out of the manhole. But city officials refused to be drawn on the cause of the initial fall. "Detailed circumstances leading up to the accident are still unknown, so it's too early for us to say anything about our responsibility," a Gyoda city official said on condition of anonymity. The four workers were retrieved and taken to the hospital where they were pronounced dead, according to local media reports. Around 10 workers were at the scene of the inspection, ordered to clean the pipes of wastewater and sludge if necessary. In May Japanese rescuers recovered the body of the dead 74-year-old truck driver months after he was swallowed by the road collapse in the city of Yashio.

Four dead after falling into manhole in Saitama
Four male workers were confirmed dead after falling into a manhole in Gyoda, Saitama Prefecture, on Saturday morning, fire authorities said. The four, all in their 50s, fell into the manhole around 9:25 a.m. during a sewage pipe inspection. Their bodies were recovered but they were later pronounced dead. According to the Saitama Prefectural Police, hydrogen sulfide was detected inside the manhole. The police suspect that the workers may have inhaled the gas. Police and other sources said that, of the seven people involved in the inspection, four fell into the manhole, which is about 60 centimeters in diameter and 12 meters deep. One of the four fell into the manhole first for an unknown reason, and three workers who tried to rescue him also fell, according to the sources. Gyoda officials said that the inspection was part of a nationwide special survey of sewage pipes. The central government asked local governments across the country to carry out the survey following a road collapse incident in Saitama's Yashio in January, which was likely caused by a sewage pipe rupture. The manhole was installed on the sewer line, which was built in fiscal 1981. The inspection was conducted by a company commissioned to do the work by the Gyoda city government. The company was making preparations to visually check the conditions of sewage pipes when the accident happened.
