Roads and footpaths have been closed and a cordon put up after a gas canniser fire broke out at a business unit in Daventry.
Emergency services are currently dealing with a fire at a business in Riley Close, on the Royal Oak Industrial Estate in Daventry.
The fire service has confirmed an acetylene gas canister is involved. The fire broke out at the cylinder’s valve manifold, and the contents have been left to burn off in a controlled way.
Fire crews from Daventry and Northampton are in attendance and a 200 metre cordon has been put in place, resulting in a number of road closures and evacuations.
Fire officer Warren Ellison said the 50 litre canister would take around three hours to burn out.
Thereafter checks will be made to make sure the valve is switched off and there will then be a cooling off period to ensure it does not pose a risk of explosion.
The incident could take around another three hours at the scene.
There is no access to Royal Oak Way North and the A45 Braunston Road is fully closed between Daventry and Braunston. Diversions through the village and onto the A361 are in place.
Braunston Road is open from the town centre to the Prospect Way roundabout.
It is anticipated the roads will remain closed for several hours and motorists, and pedestrians, are advised to find an alternative route.
The fire service and police say they are trying to be as flexible as possible with the closures due to the busy nature of the industrial estate and neighbouring Braunston Road.
If all goes to plan the roads should start to reopen around 6pm.
A number of business premises on the industrial estate have been evacuated as a precaution and the public are advised to avoid the area.
