High wall climbing is done on a wall 8’ (2.5 m) or higher, possibly to the ceiling which may incorporate many features such as slant back inclines. High walls have a belay bar at the top for “top rope climbing” or “top roping”. Each climber wears a climbing harness and helmet (recommended) and works with a belayer wearing a harness and helmet (recommended) and uses a belay device (GRI GRI).

Supervision

• Indoor MOCK-LEAD climbing instructors must be certified with a minimum of a current Association of Canadian Mountain Guides (ACMG) Indoor Climbing Gym Instructor LEVEL 2 (CGI2) and follow industry standards as outlined in the CGI Tech Manual.
• Ensure participants have completed waivers and belay tests when required.
• Ensure participants manage their personal safety while climbing
• Ensure rules are followed.
• Respond to accidents and provide first aid if required.
• Ensure participants utilise equipment in accordance with manufacturer guidelines.
• Constant, active supervision is required.
• Suggested 1:8 ratio of certified instructors to student climbers. 
• Safety and emergency procedures should be well established and rehearsed and known by all participants in all climbing settings.

Instructional Considerations

• All students must receive formal instruction including wall safety, and movement and climbing techniques. 
• Teacher / instructor should be familiar with the climbing facility. 
• Students should be allowed to select the challenge of their choice, as long as they do not exceed their own limits.
• Prior to each climb, student climbers and belayers must be checked by the instructor.
• Protection placement by students must not be allowed - pre-clipped quickdraws must be present.

Equipment / Facilities

• Ropes and associated climbing equipment designed specifically for indoor wall climbing must be used. 
• A correct base anchor plate belay system or belay off the harness, incorporating a mechanical belay system must be used. A Gri Gri is the preferred belay device for all school activities.
• A climbing helmet certified by UIAA, ASTM or CE is highly recommended for  climbers and belayers. 
• 2 1/2” mats should extend approximately 6 feet from the base of the climbing wall.
• High wall facilities should be inspected daily, monthly and annually by certified staff and on a minimum 3 year basis by a Professional Engineer.
