There are several questions developers, building owners, and project managers should ask before hiring a contractor: experience, licenses, insurance, references, warranty, timelines, and what is your safety record?
Likewise, commercial, institutional, and industrial contractors have many of their own questions about safety, specifically, “What fall protection is required on construction sites?”
Construction workers face fall hazards on rooftops, elevated platforms, ladders, unfinished building edges, open pits, and other jobsite areas. So, there is never a single answer.
The right solution depends on the hazard, surface, working height, and task. But also on the jurisdiction. Contractors need practical answers for each application.
This guide discusses the most common construction fall hazards and the fall protection solutions that address them, from exposed edges and roofs to platforms, lifelines, anchors, and ground-level exposures.
Although there are federal standards, construction fall protection requirements in Canada are set at the provincial and territorial level. All Canadian jurisdictions require protection when workers are exposed to a fall of three metres (approximately ten feet) or more. Each province and territory also has requirements for heights less than 3 metres when workers could fall into hazardous substances, machinery, or other dangerous conditions.
Due to possible differences, employers should consult the applicable Occupational Health and Safety (OHS) regulations and relevant Canadian Standards Association (CSA) guidelines, notably the CSA Z259 series for “active” fall-arrest systems.
Site-specific hazard assessments are then needed before selecting appropriate safety systems. For anyone responsible for construction safety in Canada, confirming which rules apply to each project is the first step.
There are fall hazards on a construction site wherever workers are exposed to unprotected sides, edges, holes, or openings. Common locations include:
Construction site fall protection starts by identifying every one of these exposures before work begins, then applying the Hierarchy of Controls: (1) eliminate the hazard where possible; (2) use passive protection (e.g., barriers) where feasible; (3) rely on active fall arrest when other options are not practical; (4) include administrative controls (e.g., signage, training, warning lines).
Passive fall protection in construction, such as guardrails, covers, and other barriers, requires no action from the worker to be effective. Workers do not need to connect a harness or lanyard, and a passive system can protect multiple people in the elevated work area at once.
Active systems, including personal fall arrest systems (PFAS), require proper training, inspection, and consistent use. They are often necessary where guardrails would interfere with the work or are not practical.
Since passive systems reduce human error, they are usually preferred when possible.
Exposed edges on elevated floors, mezzanines, loading areas, rooftops, and unfinished structures create serious fall exposures. Where workers need frequent, unrestricted access to an edge, use aluminum or galvanized steel guardrails, which are strong, durable, and corrosion-resistant. With a modular design, they install without welding or drilling.
Although the provinces and territories set their own requirements, Canada Occupational Health and Safety Regulations (SOR/86-304, Sections 2.12 & 2.12) provide a benchmark of standards to follow:
Roof fall protection in construction planning addresses perimeters, roof access openings, and inspections. Workers inspecting equipment or performing maintenance will face these same hazards long after construction ends, so the system must suit both the roof structure and the anticipated work.
Roof Inspection Areas: For roof inspection fall protection, review areas with passive protection, including access routes, walkways, and platforms. Where passive systems are impractical, or areas are accessed infrequently, use fall restraint and fall arrest. A restraint system uses a fixed-length lanyard to keep the worker from reaching the fall hazard. Fall arrest stops a fall in progress and requires a rescue plan. Inspect personal protective equipment (PPE) before each use, and ensure the system is recertified per the manufacturer’s recommendations.
Lifeline systems used in construction can extend protection across expansive work areas and can provide either travel restraint or fall arrest. Steep roofs generally require personal fall arrest, including a full-body harness, connecting components, a deceleration device, and an anchor point rated for the application. All components must be compatible with one another.
Horizontal Lifelines are engineered systems that can be configured for travel restraint or fall arrest. They let multiple workers move along rooftops or other elevated surfaces while remaining continuously connected. They have 316 stainless steel cables with inline energy absorbers.
Fall Protection Anchors are the foundation of any personal fall arrest system. Anchors must be rigid and rated for the intended system, supporting structure, loading, and number of authorized users. In general, anchor strength must be rated at 5,000 pounds (22 kN) per attached worker, though the regulations of the individual jurisdiction must be consulted.
When workers must reach elevated equipment, overhead installations, building services, or areas that are difficult to access safely from the ground, construction platforms provide a stable work surface for recurring tasks. They feature anti-slip, self-draining treads set in secure, stable aluminum or galvanized steel frames with integrated guardrails. These modular systems can be configured to address the fall hazard and the tasks to be performed.
Both platform types improve access and reduce the temptation of workers to use portable ladders, makeshift scaffolding, or improvised work surfaces.
Construction safety extends beyond rooftops. Ground-based fall protection may be necessary around pits, excavations, loading platforms, elevated walkways, and changes in floor elevation. It also supports roof-level work by providing safe access points.
Guardrails, barriers, and properly designed access platforms help separate workers from hazards without requiring personal protective equipment for every task.
How do We Assess a Risk on Your Rooftop?
Kee Safety Fall Protection Experts perform a critical analysis of the entire rooftop surface to identify the hazards where workers are exposed to the greatest risk. This ensures that the most dangerous areas are protected immediately with state-of-the-art fall protection systems and OH&S compliant solutions.
