WHAT TO DO IN AN EMERGENCY
I've put together a simple instruction sheet for managing an accident scene. This is taken from my experience  with accident scenes on the mountain, and is based on the Universal Life Support Algorithm, with a slant towards paragliding. It is by no means the definitive authority, but it might help to simplify things if you ever have to help at a crash scene - keep the page in the pocket of your harness. 

HAZARDS? Ensure safety of rescuer and victim

HELLO? Check responsiveness by talking to victim

HELP! Call for assistance, get someone to stand by you, phone ready.

AIRWAY If no neck injury suspected, open the airway by tilting head and lifting chin. Asses breathing. If breathing, place victim in recovery position. If not, then

BREATHING Remove obstructions from the mouth, ensure adequate tilt to head / chin lifted. Administer two rescuscitation breaths.

CIRCULATION Check pulse in throat. If no pulse, send for help (see numbers below) and begin Life Support - administer 30 chest compressions, followed by 2 rescuscitation breaths. Repeat cycle until circulation returns. Then continue with Breathing until breath returns. Then place in recovery position, and monitor both breathing and circulation every minute.

BLEEDING Major bleeding must be stopped, especially if bright red in colour (arterial blood). Put gloves on. Apply direct pressure to the wound, use a dressing, elevate the injured part above the level of the heart if safe to do so, help victim to find comfortable position if no spinal injury suspected.

INJURIES After the victim is stabilised, you can assess injuries. Expect injuries to the ankles, pelvis, back, neck, skull and internal bleeding. Try not to move the patient unless the history of the accident rules out back injury completely. After your assessment, send for help if you haven't done so yet. Ask for the helicopter rescue services unless an ambulance can do a better job. Assume that injuries are critical until a doctor in the hospital confirms otherwise.

FRACTURES Find a collar in the first aid kit, or make one up from folded newspaper or a rolled towel. Stabilise the victim's neck. Make a padded splint for any fractures by binding a rigid material as a support, by strapping the arms to the body or binding the legs to each other. Be careful not to cut off circulation by tight bandages. Take care when transferring victim to a stretcher. It is usually best to wait until the paramedics arrive before trying to move the victim.

SHOCK Treat for shock with all accident victims. Elevate feet slightly, keep patient warm, give nothing to eat or drink. If a qualified person is available, put up an intravenous drip and administer oxygen.

DIAL 112 from any cellphone, even without a SIM card.
