Police said staff were replacing the cylinder when it fell down from its position due to an insecure valve, and caused the fatal blast.
“We have received reports of casualties,” Provincial Police Region 1 chief Pol Lt-General Ampol Buarabporn said.
Police said the blast occurred at a service corner between Zone 2 and Zone 3 of the airport at a spot close to the Airport Link’s station.
The blast scene has been cordoned off. There is no report of the incident affecting the airport’s operations.
