FIRE chiefs investigating blasts and a raging blaze at a North Featherstone transport yard say the cause is “unknown”.
A West Yorkshire Fire service spokeswoman told the Express the damage at Welburn Transport, on Church Lane, was so severe a cause of the inferno could not be established.
She said: “The cause has been listed as unknown.”
Fireballs erupted into the sky as more than 30 firefighters from Castleford, Pontefract, Knottingley and Featherstone tackled the blaze in the evening on Thursday March 31.
Two men were taken to hospital with smoke inhalation and flash burns suffered in the incident, which forced hundreds of residents to flee from their homes.
Firefighters have previously said a half-full 4,500 litre diesel talk which was at the garage at the time is likely to have caused the explosions.
Police officers sent up a 200m exclusion zone around the blast site – closing nearby roads and the town’s All Saints’ CE J&I School – which firefighters cooled acetylene cylinders which they said were “in danger of exploding”.
Residents returned to their homes the following day.
