Pennygillam Industrial Estate chemical spill
Four people have suffered minor injuries in a chemical spill at an industrial estate in Cornwall.
More than 40 firefighters tackled the spill, which happened at 06:00 BST at Kensey Foods on the Pennygillam Industrial Estate in Launceston and has since been made safe.
A 50m cordon was set up around the area and a number of roads were closed.
Firefighters believe they know what the chemical is - describing it as a cleaning fluid.
Kensey Foods is a Samworth Brothers company, which produces chilled desserts and quiche.
Cornwall Fire and Rescue Service firefighters were investigating the spill, which they believe happened after a container ruptured.
A decontamination unit was at the site and a large jet was used to wash down the spill. Officials from the Environment Agency were also in attendance.
In a statement, Kensey Foods said: "Staff became aware of a suspected chemical spill in a small section close to our waste processing area.
"Three people were taken to hospital as a precautionary measure for checks.
"The affected area is close to the waste processing area and not on the main bakery production site."
The company said it was working with the fire brigade to assess the situation.
A spokeswoman for the fire service said four casualties had been confirmed at the scene and were treated by the South Western Ambulance Service.
Devon and Cornwall Police said all those taken to hospital have since been discharged.
