Emergency vehicles from past and present will be on display in Sheffield city centre this weekend.
They will be parked on The Moor as part of a 999 Fun Day for members of the public to find about how emergency services operate and to speak to emergency workers about their roles.
A bouncy castle, maze and a climbing wall will be among the attractions on offer and fire and police cadets will be on hand to give out safety tips.
They will also show children how fingerprints are taken.
A ‘smoke house’ will also be set up to highlight the conditions firefighters face when tackling blazes.
Mountain Rescue, air ambulance, coastguard and RNLI representatives will also be at the event from 11am - 4pm on Sunday, April 19.
It has been organised for the second year running.
Sandra Barley, Retail Liaison Manager for the Moor, said: “This was such a successful event in 2014 we decided to expand it this year.
“It is an opportunity to learn more about the amazing work of our emergency services as well as to understand how we could all be safer - but in a fun and accessible way that is also suitable for children.”
