More than 150 firefighters have taken part in a chemical attack exercise across Hampshire and the Isle of Wight.
The exercise at the weekend included suspected terrorist activity, a ship fire, a VIP visit, and 50 casualties suffering from exposure to an unknown substance.
It was held to test aspects of the forces operational effectiveness, command and resilience.
Mock scenarios and incidents took place in a number of locations, to help emergency crews practice for a real situation.
Hampshire Fire and Rescue Service Group Manager, Brian Rudman, said:
“Crews responded extremely well to a challenging and complex scenario that they had limited prior knowledge of.
“Exercises like this are hugely valuable and give a sense of realism it is impossible to replicate in a class room or drill yard.
“I would like to thank all those involved for their help, especially our on-call firefighters for making themselves available, to ensure this happened and their contribution to making life safer.”
Some pictures of the major exercise have been released by Hampshire Fire and Rescue Service.
