Nurses at a Merseyside hospital tested their emergency plans with a special training exercise that simulated a gas explosion in the city.
The training exercise tested how staff would treat mass injuries when dozens of patients arrived at accident and emergency.
The ‘casualties’ wearing special effects make-up were played by members of the Casualties Union, a charity which supports emergency training exercises, and members of the volunteers service of Aintree University Hospitals NHS Foundation Trust.
Mike Frayne, chief operating officer, said: “It is essential that we regularly test our emergency plans. We make sure that we learn from the feedback, build on what works well and address any issues which need improvement.
“This approach of continual improvement means that our staff are as prepared as they can be should the real thing happen.”
