School children from across the Borders have taken part in a series of workshops, teaching them about the everyday hazards that everyone faces.
Everything - from dangers in the countryside to railway safety - is covered as part the event that more than 1000 children have taken part in.
Rescuing someone from a fire is one of the staged scenarios children are responding to at an event in the Borders.
Also high on the agenda is rural safety.
It's hoped by involving these primary 7 pupils in real life situations they might remember what they have been taught.
It's the 20th year that a 'Crucial Crew' event has been run in the Scottish Borders.
This year, rail safety is a new addition.
Superintendent Andrew Allan, Lothian and Borders Police told ITV Border:
"It makes it much more memorable for them and we know from what kids have told us in years past and from some things adults have told us that the kids remember these incidents, and they have been able to use the knowledge in real scenarios to help save lives of themselves and others."
