The event was supported by Gloucestershire Fire and Rescue Service, Avon Fire and Rescue Service, SWASFT's Hazardous Area Response Team, Gloucestershire Hospitals NHS Foundation Trust, Gloucestershire Managed Services, representatives from the Cheltenham and Gloucester Casualties Union, and the Gloucestershire Local Resilience Forum.

Al Sheward, trust deputy chief executive and chief operating officer, said: ‘This exercise highlights the strength of our partnerships and the commitment of the clinical staff who volunteered their time to take part. Their willingness to engage so fully in a challenging scenario has given us invaluable insight into how real events might unfold on a busy ward.

‘I am hugely grateful to every member of staff who supported the day, as the learning gained will directly strengthen clinical preparedness and confidence. Taking part in exercises like this helps teams build resilience, refine their decision making under pressure and deepen their understanding of how emergency responses work in practice. It is an excellent example of how training together, across specialties and organisations, leads to safer care for the people who rely on our hospitals.'
