A public organization complies with the CNESST’s Regulation on occupational health and safety thanks to Delta Prevention

Case Study

During the restoration of its building, the OMH of Saint-Hyacinthe became aware of the importance of fall protection, since more than 18% of all work accidents in Quebec are caused by a fall. 

Initial situation 

The 137-unit seniors’ apartment building has undergone a metamorphosis in order, first, to bring the building up to date, but also to bring it into line with today’s standards for fall protection. The OMH appeals the canadian manufacturer Delta Prevention for its collective, permanent and non-penetrating fall protection. 

The problem 

Delta Prevention was contacted to create a configuration of safety equipment to make the roof of the OMH in Saint-Hyacinthe conform to the CNESST’s RSST. First, several ventilation ducts are located on the first roof level. Although they are not positioned in the danger zone within 2 metres (6’6″) of the edge, these devices still need a fall protection. In addition, the access ladder to the second roof level represents a second risk that had to be protected at the exit. 

The solution 

In order to delimit a visual perimeter of protection, more than 650 linear feet of VSS SafetyLine warning line have been installed. Delta Prevention’s warning line is non-penetrating and can easily be combined with a guardrail or even converted to a guardrail if OMH wants to modify its installations at a later date. To secure the corner access ladder, Delta Prevention’s team of specialists used the access ladder fall protection guardrails designed specifically for this application. As these guardrails are the most versatile on the market, it was easy for the team to design a configuration that still complies with CNESST regulations. 

Final situation 

The fall protection manufacturer’s team accompanied the OMH project manager from the initial consultation to the installation of guardrails on the roof. During all these steps, the Delta Prevention’s team ensures that your building complies with safety standards.
