going back to the opening post---
in the 2000s till 2015 i was a volunteer at the local heritage steam railway.
As the steam railway played host to 1000's of visiting children every year ( familes, school parties, special events including santa claus ), all members of staff had to undergo a police check (DBS) as we were in close proximity to children. We were specifically instructed NOT to touch the children.
I often wondered what would happen in such an emergency as post # 1
