A blaze at an industrial unit in Pimlico, Hemel Hempstead, has sparked an investigation.
Six fire crews were called to the incident at Kenwood Farm in Harthall Lane in the early hours of this morning.
Firefighters from Hemel Hempstead, Kings Langley, Garston, Watford and St Albans tackled the blaze for almost five hours after concerns about gas cylinders and overhead electricity power cables. An incident support team from Rickmansworth was also called in.
The building affected contained a car body repair shop and a metal fabrication unit, but no-one was hurt.
There is to be an investigation to confirm whether or not the fire was accidental. Another check of the area was made this morning.
Commander Greig Bescoby of Hemel Hempstead fire station’s green watch team said: “We had 16 firefighters in breathing apparatus and used about four jets, which is quite a big response, really.”
The initial call came in at 1.01am and the stop message was received at 4.45am.
> UPDATE: Herts Police visited the scene of the fire earlier today. At 2.20pm it was decided not to conduct a police investigation and the fire was recorded as non-suspicious.
Police spokesman Olivia Finucane said: “Police were required to close off both sides of the road and we conducted house-to-house enquiries. It was quite a violent blaze as there were thought to be solvents in the building which accelerated it.
“However it was decided this afternoon not to treat the fire as suspicious. Herts Fire and Rescue Service may still conduct their own investigation as to the cause of the fire.”
