EXXON Mobil Corp says that one worker was killed and another critically injured late on Monday during maintenance work at its Singapore Jurong refinery.
Exxon Mobil said in a statement on Tuesday that two contractors were found unconscious in an enclosed space filled with nitrogen.
A 34-year-old Indian national died later at a hospital while the other worker is in critical condition.
The company said it is cooperating with authorities to investigate the cause of the incident.
Exxon Mobil said it suspended maintenance at the 605,000 barrels per day capacity plant, which manufactures a wide range of fuels, lubricants and speciality products that are sold in Singapore and exported to Asia.
