Case Study | This exclusive feature was priceless for ALCOA

Case Study


Recently acquired by Alcoa, Canadian leaders in fabrication and assembly of aluminum and titanium components, this business has health and safety standards as rigorous as the quality control it uses on its products. Located in Laval, Quebec, Canada, the company supply the aeronautic industry worldwide.


It’s the health and safety manager that started the process to properly secure the roof of this impressive factory. Like most business of this level, hazard identification and prevention is a top priority to keep accident as low as possible.


As on most industrial buildings, the roof host multiple HVAC units and chimneys. Consequently, visits on the roof for maintenance are frequent and lead to constant fall safety issues. Because individual protections don’t insure the safety of everyone visiting the roof, a freestanding guardrail was chosen as the best fall protection solution for this building.

The Delta Prevention advantage

But here is the feature that really sealed the deal: Since the budget for this project didn’t allow the complete protection with freestanding guardrails, the experts at Delta Prevention suggested the use of the VSS SafetyLine in certain areas. Less pricey than the guardrail, they create a visual perimeter and share every component of the VSS system. Therefore VSS SafetyLine will be converted to VSS Classic guardrail with very limited waste as soon as additional funding is made available. This is an important and exclusive feature of Delta Prevention.


The product used is the VSS Classic freestanding guardrail and the VSS SafetyLine permanent warning line. Totally safe for the roof membrane, both products can be installed on a roof ballasted with pellets like this one. Additionally, the two roof ladders leading to the roof’s lower level are protected by self-closing ladder safety gates.


This project is a complete roof perimeter protection. A total of 620 linear feet of freestanding guardrails and 1150 linear feet of warning lines were used on this building. This project is set apart by its innovative use of two different products to protect areas of different hazard level.
