The event at Gloucester South Fire Station on Tuffley Road, Gloucester will feature a host of fun activities from fire truck demonstrations to go karts and face painting, as well as bringing home an important safe summer holiday message.
Visitors can also take a tour around the newest safety centre in the country, Skillzone, and children can take part in a safety treasure hunt with the centre's Staysafeatron robots.
In addition, the Gloucestershire Road Safety Partnership will host a mini Level 1 Bikeability session, designed to help youngsters develop the skills and confidence they need to ride their bikes safely on the road. They will be joined by the Glos Bike Project who will be offering free bike safety checks and free bike marking.
Will Windsor-Clive, cabinet member responsible for community safety, said: "Summer is the time when people are out and about more; hitting the roads for their holidays, playing water games in the garden and lighting the BBQs. We want to make sure that everyone is having fun but at the same taking simple steps to stay safe. The Safe Summer Fun Day is a perfect way to demonstrate that message."
Exhibitors on the day also include the Police, the Office of the Police & Crime Commissioner, Royal National Lifeboat Institution, British Red Cross and The Gloucester Bike Project.
Stewart Edgar, Chief Fire Officer for Gloucestershire Fire & Rescue Service, said: "As well as being a fantastic day packed full of fun activities to keep you entertained, the flagship event will send out a really important summer safe message. We will also be using Twitter and Facebook in the weeks leading up to the event to promote top safety tips covering road safety, fire safety and water safety."
