Hundreds of firefighters from across the country will be in Alrewas for a ceremony at the National Memorial Arboretum.
The Annual International Service of Thanksgiving will be held on May 10.
The Firefighters Memorial Trust will host the event, which starts at 11.30am, with the support of Staffordshire Fire and Rescue Service.
Staffordshire’s Chief Fire Officer Peter Dartford will be attending the ceremony as President of the Chief Fire Officers Association.
He said: “It is once again a privilege to welcome colleagues from across the United Kingdom to Staffordshire for this ceremony of thanksgiving and remembrance.
“It is particularly pertinent at the moment with firefighters from across the UK currently in Nepal assisting their colleagues in the aftermath of the earthquake in Nepal which has claimed the lives of thousands of people.
“Firefighters risk their lives on a daily basis in order to keep the communities that they serve safe. Their courage and dedication is an inspiration as they deal with major incidents such as wildfires that can destroy entire communities to house fires and road traffic collisions which threaten the lives of those involved.
“The Annual International Service of Thanksgiving is always an incredibly moving occasion where we say thank-you to serving crew members and take the time to remember and appreciate our colleagues who have sacrificed their own lives in order to help others.”
Former and serving firefighters, their families and friends as well as members of the public are invited to attend the service.
The National Fire Cadets will provide a guard of honour and co-ordinate the laying of wreaths.
The Band of the West Midlands Fire Service will perform along with the Pipe Band of the West Midlands Fire Service. The Choir of Cheshire Fire and Rescue Service will also be performing.
