Firefighters battled blazing pallets and exploding gas cylinders in Grangemouth.
Six appliances from Falkirk fire station and a water carrier from Dunblane sped to Grangemouth Pallets in Clyde Street just before 11 p.m. on Saturday after receiving 20 calls from nearby residents.
The fire, believed to have been started deliberately, was sweeping through the storage yard when fire personnel arrived and they had to deal with the added danger of gas cylinders - several of which exploded while they used hose reel jets to extinguish the blaze.
Firefighters had the incident under control and the area safe by 4 a.m. on Sunday and Central Scotland Fire and Rescue Service confirmed they were investigating the cause of the fire.
Central Scotland Police, meanwhile, arrested one man in connection with the incident.
Community police officer Sarah Whelan said: “We would like to thank the local residents for their quick actions in calling the fire brigade.”
