Police have closed a main road near a pyrotechnics factory where a man was killed in a huge explosion last month.
Part of the building was completely demolished in the explosion
The A343 at Middle Wallop, near Andover in Hampshire, will be shut on Saturday and Sunday to allow for a clear-up at the Wallop Defence Systems factory.
It follows a blast at the building on 26 June, which killed factory worker Anthony Sheridan, 37, of Over Wallop.
A 500-metre ground exclusion zone and a 1000-metre air exclusion zone will be in place around the factory.
Residents living in four properties within the exclusion zone are also being evacuated.
The explosion took place in a building used to produce explosive flares.
Police said the closure is a precaution in the unlikely event that any unexploded materials are found at the seat of the explosion.
Local diversions will be in place and people driving in the area are being advised to allow extra time for their journey.
Work at the factory, which has been closed since the explosion, is expected to return to normal from next week.
A joint investigation by Hampshire Constabulary and the Health and Safety Executive (HSE) into the cause of the blast continues.
