Use of skis and poles.—When putting on skis on a high-angle slope, put the lower ski on first. It will then serve as a barracade for the other ski and other equipment which might otherwise escape.
Do not put the hands through the pole straps. In a fall one must be able quickly to slide the hand down the shaft in order to use the pole to brake the fall.
In falling, the skier should become adept at swinging the skis below the body and across the slope. A slide can seldom be stopped otherwise.
When standing upon or traversing a hard and steep surface, insert the lower pole in the snow beside the lower ski to prevent a surprise slip.
