This Ontario Public School Complies With NBC Standards.

Case Study

More than 150 linear feet of guardrails installed on Hillcrest Public School to improve the safety of its workers and contractors.

Initial Situation

The school board of Hillcrest Public School, located in Petrolia, Ontario, had issued a tender for some major renovations to be completed over the summer. As part of this tender, the Roof Consultant recognized that many HVAC units on the roof needed to be protected with guardrail & that the existing guardrails were not compliant.

The Problem

The school wanted to replace outdated guardrails with a product that would not damage the roof membrane and would also withstand the Canadian climate. The roof consultant wrote in the specification to replace the existing section of guardrail with a fall protection solution that would meet their strict requirements for an acceptable system.

The Solution

To replace non-compliant guards, Delta Prevention were approved as the replacement product since they are perfectly suited to the situation. These products are self-supporting, i.e. they are supported by counterweights made of recycled rubber. Aluminium and rubber, the main components of the products, provide resistance to rust and deterioration caused by temperature changes.

In addition, the installation of Delta Prevention products provided protection around the heating, ventilation and air conditioning elements, all located at the roof edge. This provision, which is dangerous for users, had to be protected by complying with NBC standards. Each HVAC unit is now protected by a VSS Compact guardrail. In all, eight guardrail sections totaling more than 150 linear feet were installed on the roof.

The Final Situation

Ultimately, the Delta Prevention perforation-free guardrails complement the Hillcrest Public School roof repair as well as the installation requires no perforation. Maintenance operations are now carried out safely, without the use of harnesses or other personal protective equipment (PPE), in addition to speeding up work deadlines.
