TWO factory workers had to be taken to hospital following a chemical spill at a site in Holbeach St Marks.
Bakkavor Pizza on Sluice Road had to be evacuated and about 30 firefighters called in just before 9pm on Saturday.
Two staff members were left suffering from breathing difficulties from the incident, which was caused by an overconcentration of a chemical.
They were given oxygen before paramedics arrived on the scene and were later taken to hospital after showering and changing their clothes.
A spokesman for Lincolnshire Fire and Rescue said Bakkavor workers had diluted a cleaning agent down and flushed the area before fire crews arrived.
Fire crews then cordoned off the area and carried out investigations. No chemicals entered any of the drains.
Fire crews responded from Holbeach, Long Sutton, Spalding, Donington, Market Rasen, Boston and Grantham.
A spokesman for Bakkavor said: “We can confirm that there was an incident of a chemical spill on Saturday evening at the Bakkavor Pizza site in Holbeach St Marks.
“The correct procedures were followed – the factory was evacuated and the emergency services called.
“Two employees were treated at the site and taken to hospital as a precaution. Both employees were released early on Sunday morning and both are well.
“The site is currently investigating the cause of the incident to ensure this can be avoided in the future.”
