A group known as the Rescue Riders is training bikers around the country in first aid and what to do at an accident scene. This training is for that period of time between the incident and when emergency services arrive.
This is a non profit organization that works with accident scene management. If you've ever seen someone go down on a bike you know this training is worth having.
It's at least worth a look, here is their website
