On Tuesday 21st June 2022, Greater Manchester Fire and Rescue Service hosted Exercise Mitchell, a large-scale training exercise at their Bury Training and Safety Centre. The exercise focused on testing the multi-agency operational response to a CBRNE incident by working with partners and volunteers. Volunteers were on hand to play the part of casualties following a chemical incident on a tram. Greater Manchester Police (GMP), Greater Manchester Fire and Rescue Service (GMFRS), North West Ambulance Service (NWAS), Transport for Greater Manchester (TFfG) and other partners responded to the incident. The exercise commenced with joint working between emergency service control rooms in the early stages of the incident, with several calls being made on 999 calls reporting an incident had occurred on the tram. It took the form of a multi-agency response to the incident in the morning, working with GMP and NWAS. Later in the afternoon crews also set up and tested the Mass Decontamination Unit, helping volunteers through the process. This training helps to reinforce understanding of different agencies roles and responsibilities during the response to such an incident and validate learning from the response to previous Major Incidents in Greater Manchester. The exercise also reinforced JESIP principles and procedures to help embed multi-agency working amongst Greater Manchester and regional partners. Further elements of the exercise will take place later in the year, focusing on the Strategic Coordinating Group (SCG) and Tactical Coordinating Group (TCG) elements of a Major Incident. The overall exercise helped to test the multi-agency response at the Strategic, Tactical and Operational levels including looking at the operational response, Local Resilience Forum procedures and interoperability between organisations.
