The cause of a blaze at the West Cumberland Hospital site last weekend has been discovered by investigators.
Cumbria Fire & Rescue Service and Cumbria led the investigation after the three-storey portable building, near the main entrance of the Whitehaven hospital, caught fire on Saturday.
A spokesman for Cumbria Fire and Rescue Service said: “The investigation concluded that the cause of the fire was due to an electrical defect of equipment resulting in the accidental ignition of flammable material and the spread of the fire.”
A spokesman for the Health and Safety Executive said: “We are aware of the incident but the investigation has been carried out by the fire service rather than ourselves.”
Several fire crews from across the county were called to tackle the blaze just after 7pm on Saturday.
At least five fire engines, an aerial ladder platform and joint incident command unit attended the scene.
The fire was extinguished at around 3am on Sunday.
The portable buildings are part of the redevelopment of the hospital site.
They were being used as office space by contractor Graham, which is managing the multi-million-pound redevelopment.
Roads were closed around the hospital and the North Cumbria Integrated Care NHS Foundation Trust said there was no risk to patients. A spokesman thanked its teams and said Graham would assess the damage.
