Thanks to the bmfa for the information on this app, I highly recommend you download it to your phone and like me hope you never need it.
Our sport of model aircraft flying has a long proven track record of being a very safe sport to participate in, however accidents can happen or we or our fellow fliers may be taken ill at anytime. Would you be able to help if someone was injured or taken ill? First Aid training is very worthwhile and should be considered and it is always wise to have a personal first aid kit with you and a well stocked kit available at clubs if possible.
Having the knowledge to be able to help when these things happen could save some one life, there are now some free First Aid apps that you can download to your smart phone with lots of step by step guides explaining what to do in the event of medical emergencies. Consider adding one to your phone. Hopefully you will never need to call on them but they could prove very useful if needed.
