STOP   Potential danger ahead. This signal means that you must stop. You should then walk along the shore to the lead canoe and inspect the rapids. The first people to see the signal must reproduce it for those behind. Hold your paddle horizontally above your head and then raise and lower it. If you are outside your canoe, raise and lower both arms simultaneously. Wait for the next signal before continuing on your way.

HELP/ASSISTANCE REQUIRED Provide assistance as soon as possible. Remember that even though you must reach the site of the emergency as quickly as possible, you should keep calm and not endanger the lives of the rescuers. If you have a whistle, blow three long blasts to signal others. As a visual signal, raise your arm over your head and wave it from side to side. For a clearer signal, use a highly visible object such as a personal flotation device or throw bag. If you are in your canoe, raise your oar vertically and wave it from side to side.

ALL CLEAR This signal can also mean “permission requested” if it is given by someone about to proceed into a certain section of the route (in other words, “is it safe to go on?”). At that time, the leader must raise his/her arm or paddle vertically and hold it still. This will clearly signify “all clear” or “permission granted”.
