Scaffolding at a building site has collapsed, injuring three workers.  What should your priority be:

Assess the scene for danger - you don't want to get hurt.  If you're injured you can't help anyone else.

What should you do next:

Assess the casualties you want to start helping.  It's now safe to assess the casualties and decide who to help first.

Of the three casualties on the ground, which should you help first:

The quiet casualty who's laying face up - you can’t even tell if he's breathing.  A quiet casualty may be an indication that the person is unconscious.  Such casualties should always be the first priority.  A casualty who's bleeding heavily or is obviously in pain is upsetting but a quiet casualty could be in the most serious condition and should always be attended to first.
