Two contract workers died after inhaling toxic gas while cleaning a 15-foot-deep stormwater drain sump maintained by the Greater Chennai Corporation in Thendral Nagar, Kodungaiyur, on Monday afternoon, according to a report by Times of India – Chennai.
The deceased have been identified as Naveen and Ahmed Basha. The workers were carrying out cleaning work inside the sump when they were exposed to the gas, the report said. The available account did not provide details about the contractor responsible for the work or the safety equipment used at the site.
Fire and Rescue Services personnel from Madhavaram were called to the location after the incident. They recovered both bodies from the sump and sent them for postmortem examination. The report did not specify the time taken for the rescue operation or whether any other workers were present at the site.
The sump is part of the stormwater drainage infrastructure maintained by the Greater Chennai Corporation. Such underground and enclosed municipal structures can pose serious risks during cleaning and maintenance because gases may accumulate in confined spaces. The circumstances of this incident, including the nature of the toxic gas and how exposure occurred, have not been established in the information available.
The deaths bring the safety of workers engaged in essential urban maintenance into focus. Stormwater drains, sumps and related infrastructure require regular cleaning to remain operational, particularly in a city where drainage capacity is closely linked to flood management. The incident occurred during work on a civic drainage asset, but the report did not state whether the activity was part of routine maintenance or an emergency operation.
The Greater Chennai Corporation maintains the sump, while the deceased workers were identified as contract workers. The report did not include a statement from the corporation, the contractor, the police or the workers’ families on the incident. It also did not provide information on possible compensation, responsibility for the worksite or any immediate changes to cleaning operations.
Further investigation is under way. The postmortem examinations are expected to form part of the inquiry into the deaths, while authorities are yet to release additional details about the incident or the safety procedures followed during the cleaning work.
