BARRY B-NET SYSTEM • INSTALLATION GUIDELINES rev. 5 

3. Before use 

 

These installation guidelines apply exclusively to factory assembled Barry B-Net Systems. Use of 
individual components outside of factory assembled Barry B-Net Systems, and/or any substitution or 
modification of any components may cause serious injury or death and voids product warranty. 

 

Alpine skiing is a potentially dangerous sport and the Barry B-Net System should be installed in conformity with 
these installation guidelines. Installation (in whole or in part) made outside of these installation guidelines must 
be made under the supervision of a qualified authority (see below). The efficacy of the Barry B-Net System may be 
seriously compromised if any of the basic requirements are modified. Any installation of safety net systems 
should be documented and conducted under the supervision of a qualified authority, who will be responsible for 
the entire period that the safety nets are installed and used and who shall provide ongoing instructions for 
personnel for any required adjustments to be made. 

 

 

Barry recommends that Barry B-Net Systems be installed during training and with the same standard of care and 
concern as would be given during a race. Risk of a skier fall may be greater during training as more runs are 
performed and often new equipment and techniques are tested during training and speed may be greater. 

 
 

3.1 Training 

 

Important:

 Installation situations which are not described in these pages are to be resolved and corrected by a 

qualified authority.   
 
The installation of Barry B-Net

 

Systems must only be carried out by personnel who have received and reviewed all 

of the information contained in the current version of this document. The electronic version found on the Barry 
website is the only valid version as product updates or changes may be done from time to time without prior 
notification.

 

 

Authorized person

means a person approved or assigned by the Race Organizing Committee or other entity to 

perform a specific type of duty or duties at a specific location on the race or training course. 

 

Competent person

means one who is capable of identifying existing and predictable hazards in the 

surroundings or training or race conditions which are unsafe, hazardous and/or dangerous to the skiers or 
personnel in the vicinity of the event, and who has authorization to take prompt corrective measures to eliminate 
them.

 

 

Qualified authority

means one, who, by possession of a recognized degree, certificate, or professional standing, 

or who by extensive knowledge, training, and experience, has successfully demonstrated his/her ability to solve 
or resolve problems relating to the subject matter, the work, or the project.

 

 
All installation scenarios should be documented and include a list of the personnel who participated in the 
installation.
