Firemen tackle chemical incident in Pensilva
Firefighters in Cornwall have been dealing with a chemical incident after containers were found to be leaking.
About 40 firefighters attended the incident at Pensilva Industrial Estate after they were alerted at about 1530 GMT on Thursday.
The fire service said the liquid has now been identified as sodium hydroxide and originated from one container.
An initial cordon of 50m (0.05km) was set up but has since been reduced to 20m (0.02km).
During the incident six firefighters wore gas-tight chemical protection suits and breathing apparatus to deal with the chemical spillage.
