A tragic incident occurred at the Choa Chu Kang Waterworks in Singapore, where a sub-contractor working for PUB, Singapore’s National Water Agency, succumbed to injuries caused by inhaling hydrogen sulphide gas. The accident took place during routine tank cleaning operations on Thursday, May 23.
Details of the Incident
The deceased, along with two other colleagues, all foreign workers, were performing tank cleaning when they collapsed due to the inhalation of hydrogen sulphide—a toxic gas commonly produced as a by-product in the water treatment process. The exposure occurred despite the routine nature of their work, underscoring the potential dangers associated with water treatment facilities.
Emergency Response and Medical Treatment
Upon discovering the unconscious workers, emergency protocols were initiated, and the Singapore Civil Defence Force (SCDF) was called to the scene. The workers were immediately transported to Ng Teng Fong General Hospital. Despite efforts to revive them, including cardiopulmonary resuscitation performed during the ambulance journey, one worker was pronounced dead. The other two workers were placed in intensive care due to the severity of their conditions.
Investigation and Safety Measures
Preliminary investigations by PUB suggest that the accident was caused by the inhalation of hydrogen sulphide gas. This incident has prompted a review of safety measures at the facility to prevent such occurrences in the future. The focus will likely be on enhancing safety protocols, ensuring proper protective gear usage, and possibly revising procedures for handling hazardous materials.
