Warning Line Systems in Calgary

Are you looking for a warning line to protect workers on your next Calgary-based project? Then you’ve come to the right place. At Delta Prevention, we offer warning line systems in Calgary that help businesses keep their employees and workers safe. When it comes to rooftop safety, a warning line system is an important element.  

What is a Warning Line System?

A warning line system consists of a steel cable coated in yellow nylon with PVC safety flags that runs along a stretch of aluminum posts. The posts are secured by rubber bases that do not penetrate the membrane and act as a counterweight. The whole systems in pre-engineered and thus acting in compliance with the permanent warning line standards in Alberta. 

The purpose of a warning line system is to ensure the safety of rooftop workers, which is achieved by placing the line at a minimum of 2 meters from the edge of the roof, or from any place the worker is at risk of falling. Put simply: the warning line system is an easy and cost-effective way to block access to the perimeter of a roof.
