For secondary lengths longer than 25 feet what are the risk or hazards associated with this scenario? Some lengths found are up to 700 feet, but are not accessible to the public and on site there is 24/7 maintenance staff.
The risks and hazards are no different than when limited to 25'. However, the probability of an undesired event will be factored by the multiple of that distance... perhaps a bit more if we consider the less obvious, such as line of sight, communicability, structural changes, etc.
Even in a supervised industrial installation you are limited to 100' for compliance.
