arrived on / at the scene
Eight people were injured in an early morning fire at a flat at Tah Ching Road in Jurong.The Singapore Civil Defence Force (SCDF) said it received a call at 4.30am about the fire at Block 337B.
The fire was confined to the living room of the affected unit on the 15th floor.
SCDF said the unit’s six occupants had self—evacuated by the time SCDF personnel arrived on the scene. The other two are neighbours.
The fire was put out within eight minutes.
The above is from a local newspaper. I wonder if 'on' is correct. In my opinion, 'at' should be used.
Re: arrived on / at the scene
Both 'on' and 'at' are fine.
