A Birmingham cannabis factory went up in flames on Sunday injuring two people.
The two-storey, semi-detached house was being used to grow the plants.
A total of three appliances were called to the property, in Ward End, at 9.15 am.
The two individuals rescued from the house are now in comas, according to the West Midlands Fire and Rescue Service.
Sean Tomkins, fire investigation officer, told info4fire that the biggest fire safety risks in cannabis factories was the unusually large amount of heat and electricity running through a property.
“The normal electricity metre in a house is bypassed so that electricity is not metered or regulated,” he said.
Firefighting in these properties can also be very dangerous, he said, because fire spread can be unpredictable.
“[Growers] may also have destroyed a building’s integrity by removing doors and putting holes in ceilings and walls so that cables and huge ventilation tubes can run through. They use the tubes to control odours from the plants.”
In the past year, there have been more than 50 cannabis factory fires in the West Midlands area alone.
A joint police and fire service investigation is ongoing.
