Design, Installation, and Maintenance of Permanent Rooftop Anchors in Saskatchewan

The emphasis and scrutiny on safety in the workplace is increasing every day, and although significant advancements have been made in the field of fall protection, Canada (and specifically, Saskatchewan) still lags behind our neighbors in the US and significantly lags behind many European countries. One area of fall protection that is often misunderstood and overlooked is the design, installation, and maintenance of permanent roof top anchors.

Saskatchewan OH&S regulations require fall protection to be present anytime a worker could fall 3m or more. This means that most buildings could benefit from having permanent roof top anchors for workers to tie to while working near the leading edge. Furthermore, many multi-story buildings require rooftop anchors to allow for window washing and maintenance. It is important to consider the need for these anchors during the design phase of new buildings. The cost of installing these anchors during a new build, when structural members are exposed and accessible is significantly lower than having to open up a sealed roofing system to install them once the building is completed. So, what do designers, owners, and users need to know about permanent rooftop anchors?

According to the Saskatchewan OH&S regulations, a permanent rooftop anchor must have an ultimate load capacity of at least 22.2 kN (5000 lbs). Given this requirement, most of the anchors on the market are rated for at least 5000 lbs, so why is it even important to be aware of this requirement? Although the anchor itself might be rated for 5000 lbs, the substrate that it is fastened to and the fasteners themselves must also be capable of supporting a 5000 lb load. With the ever increasing liability placed on owners and designers, this means that it is always a good idea to have a professional engineer review the design prior to installation. The best resource for fall protection engineers is the CSA standards, and any engineer who is designing a permanent rooftop anchor should have in-depth knowledge of CSA Z259.16 (“Design of Active Fall Protection Systems”). For anchors intended for suspended access, CSA Z271 (“Safety Code for Suspended Platforms”) is a terrific resource.

In regards to installation, permanent rooftop anchors should be installed as per the manufacturer or supervising engineer’s instructions and should always be installed by competent workers who have experience with fall protection systems. CSA fall protection standards are unique in that they require sealed as-built drawings, which is meant to ensure that the certifying engineer is involved throughout the entire project and properly reviews the installation once completed.

Once the anchors are installed, it is important that they are maintained properly. All permanent roof top anchors should be inspected at least annually by a professional engineer or a qualified person under the supervision of an engineer. It is important for building owners to ensure that these inspections are carried out each year to keep users safe and to limit liability.
