3.2 Design premise

The installation scenarios illustrated herein are based on observations of an 80 kg mass travelling at a maximum

speed of 60 km/hr and/or at a maximum speed of 100km/hr, impacting the net/support pole system sideways.

Direct impacts (whether head first or sideways) into the net system, without prior sliding of the skier on the snow

surface, may cause the skier to ramp up, flip or be ejected and may result in serious injury or even death.

Typical use is during alpine ski racing or training, on courses which are wide (40 m +) and which are homologated

for slalom or giant slalom and where the minimum distance from a turning gate to the first row of netting is 6 m.

Installation scenarios which fall outside the above design premise are to be determined by the on-site qualified

authority and may require that appropriate compensatory measures be taken.

3.3 Preparation

Step 1: Inspect equipment before use (see Appendix A). Do not use if you have any doubts about the installation

of this product or if you suspect that the materials may be damaged or unfit for use, or has exceeded its service

life.

Step 2: Identify potential obstacles to the trail (snow gun, trees, tower, etc.). Both sides of the entire race course

should be protected by Barry B-Net Systems for all training and race events as the skier's probable spill zones may

not be accurately predicted. In addition, where appropriate, follow the safety recommendations provided in the

course homologation report and add nets or other protection means to account for speed, mass and skier ability

as determined by a qualified authority.

3.4 Types of configuration

The installation configurations provided herein serve as basic guidelines which have been found to be effective

under certain conditions. Other configurations are also possible and should be implemented under the

supervision of a qualified authority. The installation configuration is done further to evaluation and analysis by

the qualified authority of several factors such as the expected speed and level of the skier, the angle of impact

between the potential fall of the skier and the obstacle, etc. Barry recommends to always have spare components

or systems readily available for repair in case of loss, damage or if needed to increase safety if conditions change.
