Fire crews were called at 10.30pm on Tuesday (15 December) to reports of a fire at Drayton Manor theme park.
Four water pumps, a water carrier and an aerial platform attended the blaze at a toilet block in an area of the park.
The fire, which covered an area of 30m by 10m, was fast to develop due to the wooden roof construction of the building.
Flames were approximately 25 to 30m in height at the peak of the fire.
A total of 28 fire service personnel attended the scene, with the blaze put out at approximately 2am on Wednesday 16 December.
The fire was put out after crews broke through the roof of an adjoining building and used jets to prevent the blaze from spreading.
A fire appliance remained at the site, damping down hotspots, all night and this morning, in order to support the fire investigation.
Incident Commander Stuart Ruckledge said: “When I arrived I was concerned about the embers from the wooden roof structure catching on other nearby buildings, but thanks to the quick work of the first crews at the scene, Tamworth and Mercia, we were able to stop the spread.
“The on-site theme park staff were also very helpful in allowing us to use a golf buggy to run our hose and portable pumps across the site, were on hand to isolate the electrics and also answered questions about what was in certain areas including anything hazardous to crews.”
“Fire Safety Officers will support the park management during this already stressful time to ensure that further incidents are avoided."
