There are hierarchies in nature (like taxonomy and the food chain) as well as social structures. For example, the Hierarchy of Medical Triage starts with the Chief Surgeon at the top, then moves down to the Attending Physician, Resident, Intern, Nurse Practitioner, and Nursing Staff.
The hope is that your organization never has contact with a medical hierarchy due to a workplace fall.
Falls from height are a significant cause of serious workplace injuries and fatalities in Canada, making effective work-at-height safety programs a critical part of any workplace safety Canada initiative. To combat these workplace fall risks, safety professionals use their own hierarchy: the Hierarchy of Fall Protection.
The fall protection hierarchy is a framework that prioritizes the most effective methods of protection before relying on personal protective equipment (PPE) and worker behavior. It helps organizations select controls that reduce risk at its source whenever possible, moving down the hierarchy only when higher-level controls are not feasible.
By understanding each level and applying the right engineered solutions, employers can design and operate safer facilities that comply with applicable Canadian safety regulations and standards.
The hierarchy of fall protection follows a progression from the most effective protective measures to those that rely more heavily on worker training and behavior.
Whenever possible, work should be redesigned so employees do not need to work at height. Can equipment be moved to the ground level for maintenance? Can remote monitors or drones be used for inspections? Elimination may not be practical, but it should be the first option considered when designing the facility.
When hazards cannot be eliminated, passive fall protection is the preferred solution because it protects workers without requiring their active participation or special training. Passive systems are physical barriers that remain in place and collectively protect everyone. They are as numerous as they are effective in mitigating workplace fall risks.
Where passive barriers are impractical or not in place, fall restraint systems use harnesses, lanyards, lifelines, and anchors to limit how far a worker can travel, keeping them safely back from a leading edge. These systems require proper design, equipment selection, and worker training to function reliably. They should also be inspected before and after every use for damage and wear.
In the event of a fall, a fall arrest system serves as the final engineered layer of personal protection. They are designed to safely stop a fall in progress, arresting it quickly while minimizing the forces on the worker’s body. Fall arrest systems require rescue planning, regular inspections, and ongoing training to perform effectively during an emergency.
At the base of the hierarchy are procedures, training, signage, and warning systems, which depend on awareness and consistent human behavior. Although they complement a strong safety culture and support overall workplace safety Canada compliance efforts, they are the least reliable controls on their own.
Instead of using PPE as a default, organizations should select the appropriate level of protection based on the task to be performed and a proper risk assessment.
The most effective workplace fall prevention strategies integrate multiple solutions. A facility might use roof guardrails around a rooftop perimeter, anti-slip walkways to route foot traffic safely, and horizontal lifeline systems with roof anchor systems for tasks that still require personal fall protection.
By applying the fall protection hierarchy and selecting engineered solutions matched to each level of risk, companies can strengthen their workplace fall prevention efforts, create safer, more productive environments, and ensure effective, long-term work-at-height safety.
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.
