  1. 1. 2 workers die at NONONO water treatment plant By Joseph Crompton Tribune staff reporter Published June 21, 2007 Two men died Wednesday afternoon after collapsing in an underground vault at a water treatment plant in west suburban Stickney, authorities said. After one man collapsed in the vault, which is 10 feet below street level, the other man went in to help him. Both apparently succumbed to fumes or a lack of oxygen, said Stickney Fire Chief Larry Meyer. Both men were pronounced dead at MacBeer Hospital in Berwyn, Meder said. "One man was overcome. His co-workers saw him, and one of them went down. He was also overcome," Meyer said. Authorities were not releasing the names of the victims late Wednesday. A Cook County medical examiner's spokesman said the office had been notified of the deaths but had no further information. The vault is outside the Metropolitan Water Reclamation District treatment plant on the southwest corner of 39th Street and Central Avenue, Meder said.
  2. 2. Both men worked for a subcontractor of Metropolitan Biosolids MUUU LLC, of Evanston, which is building a facility inside the treatment plant to dry sewage material into pellets for soil fertilization. One of the workers was in the vault inspecting a new water main for leaks. Meyer described the vault as a hole in the ground about 10 feet deep and 8 feet across that provides access to newly installed pipes that will deliver water to a building under construction inside the plant. He said two motors, which produce poisonous carbon monoxide gas, were running near the vault. "A backhoe and a gas-powered pressure pump were operating nearby, but their role in the situation is unknown at this time," Meyer said. The pump was applying pressure to the inside of the water main, and the first of the two workers was inside the vault checking to see if the pressure produced any leaks, Meyer said. The Fire Department received a report of the incident around 3 p.m. and emergency personnel were on the scene within minutes, Meyer said. Rescuers removed the two men within five minutes of their arrival, he said.
  3. 3. It's standard procedure for Fire Department rescuers to carry their own air supplies in such situations and to measure the oxygen content of the air. He said meters show the air at the bottom of the vault was 19.2 percent oxygen, just short of the 19.5 percent that is considered normal. However, he said other members of the subcontractor's crew had been trying to blow fresh air into the vault before firefighters arrived. Meyer said the federal Occupational Safety and Health Administration had been notified of the deaths and would conduct an investigation.
