Staff at businesses in a Fife industrial estate were evacuated after a second fire to hit the site in just over a fortnight.
Fire crews were called to Gray Fabrication on the Cupar Trading estate at 11.30am on Thursday.
The heavy steel fabrication company is just a stone’s throw from Aberhill Metals, a scrap metal company which went up in flames on July 21.
Firefighters spent three days battling the Aberhill blaze, during which eyewitnesses reported hearing explosions and plumes of smoke could be seen as far afield as Angus.
Crews from Cupar, Auchtermuchty and Methil were called to today’s incident, which involved a cylinder of highly flammable gas.
They spent three hours cooling the cylinder to bring the fire under control.
A spokeswoman for the Scottish Fire and Rescue Service said: “We attended at Gray Fabrication in the Cupar trading estate at 11.33am due to a report of an acetylene cylinder alight in a workshop.
“Crews from Cupar, Auchtermuchty and Methil attended an applied cooling water to the cylinder to allow the rest of the acetylene gas to burn off from the valve. It was monitored using a thermal imaging camera.
“Those in nearby properties were asked to evacuate.”
