Forty firefighters have tackled a blaze at a paint production factory in Cheslyn Hay.
"This was a large scale incident which involved approximately 40 firefighters from across Staffordshire and the West Midlands."
Cannock Station Manager Neil Pederson
The fire broke out shortly before 12.30pm yesterday in the yard of Cheslyn Dispersions Ltd, Landywood Lane.
Crews from Cannock, Chase Terrace, Penkridge, Bloxwich and Walsall attended the fire along with the incident response unit from Newcastle and the welfare vehicle from Rugeley.
Firefighters wore breathing apparatus and used main jets to tackle the blaze.
It started accidentally when dry paint powder which was being stored in a 40 foot long shipping container overheated and caused a chemical reaction.
The subsequent build-up of pressure created was so powerful that it burst a wall of the container, enabling the fire to spread to piles of nearby pallets.
Cannock Station Manager Neil Pederson, who led the incident, said: "This was a large scale incident which involved approximately 40 firefighters from across Staffordshire and the West Midlands.
"It took over five hours to put the blaze out and due to the chemicals involved, it was a delicate operation which could have had a far worse outcome. Thankfully, no-one was hurt as a result of this incident.
"Our business support and fire safety teams will be working closely with the owner of the company to look at ways of improving site safety in order to avoid further incidents occurring in the future."
