Cornwall Blue Light Day is an annual event which helps break down barriers between individuals with learning disabilities and the emergency services.
This year marks the 11th Blue Light Day in Cornwall.
PCC Alison Hernandez said: "Events like these are so important. It is vital that vulnerable people in our communities know how to contact the emergency services if they need them.
"Our ability to reach so many people at one event and to help teach them to be safe is fantastic - and all whilst having fun!"
