4.6 Verification and validation
The validation step is very important and is to be carried out by qualified authority or by competent persons prior
to the use of the systems. Inspect carefully the following to confirm that the systems are ready to be used.
Stopping distance: The distance between the rows of nets and obstacles must be at minimum as per the
distances established. All efforts should be made to increase this distance whenever it is possible. Ideally a 5-6
meters minimum distance is preferred. Each additional meter provides an increased factor of safety.
Base of Nets and Support Poles: The base of the nets should skirt over the snow surface and drape towards the
race course side. There should be no gaps between the bottom of the net and the snow surface. The base of nets
and the support poles should not be buried under and/or frozen in the snow or ice.
Net tension: Netting should hang not too tight or too loose.
Assembly: The uphill net must be on the race course side. All connecting loops must be well assembled.
During the period of time from initial deployment of the system, throughout the duration of the race or training
event, continuously monitor the system and ensure to account for varying conditions such as snow
accumulation/ablation, snow density, and impact from skiers, etc.
Constant re-evaluation and making the necessary adjustments and/ or repairs as detailed herein, is essential to
account for these variations.
