Ensure you are safe on the slopes and warn other skiers/boarders on the piste. You can do this by using your skis to make a cross slightly further up the piste, warning other skiers making their way down that there is a potential hazard.
Contact the Emergency Number you receive in your departure email (on your E.Ticket). Inform the team which resort you are in, and they can help explain what you need to do or who to call next.
You can also contact the Resort Emergency number on the resort piste maps too.
