Protect Workers at Heights with Reliable Horizontal Lifeline Systems


Daredevils have walked across Niagara Falls on a tightrope, a tensioned horizontal rope or cable, since at least 1859 when Jean Francois Gravelet—The Great Blondin—traversed the Great Cataract.

Most recently, in 2012, Nik Wallenda crossed from the American to the Canadian side of the falls. Since guy wires could not be installed to stabilize the tightrope, he had to wear a harness with a lifeline that tethered him to the cable stretched over Horseshoe Falls.

The Wallenda stunt was unusual because the thrill of watching tightrope walkers often stems from the lack of fall protection systems.

Not having fall protection does not fly for workers who inspect, maintain, and repair building services equipment housed on the rooftop. Fortunately, they can rely on horizontal lifeline systems with secure anchor points to perform their tasks safely and productively.

The Importance of Horizontal Lifelines for Rooftop Work

Since falls from height are a leading cause of workplace injuries and fatalities, federal, provincial, and territorial agencies require rooftop fall protection solutions. Wherever guardrails are impractical, lifeline safety systems for roofs should be used to provide compliant fall protection. A horizontal lifeline with a roof anchor system will provide continuous, secure attachment points, reducing the risk of falls and injuries while allowing workers to move freely.

Engineered horizontal lifelines span a distance between two or more points, creating a flexible yet sturdy connection for the worker wearing a personal fall arrest system (PFAS), which includes a harness, lanyard, and cable or rope lifeline. The system features a tensioned stainless steel cable that runs between roof anchors. All components are made of strong, durable, and corrosion-resistant stainless or galvanized steel.

Rooftop horizontal lifelines provide both travel restraint and fall arrest. Travel restraint prevents workers secured to the system from reaching fall hazards, such as the roof edge and unprotected skylights. In case of a fall, the horizontal lifeline absorbs the forces generated and reduces the impact on the body, preventing severe injury.

Horizontal Lifelines are Ideal for Essential Uses:

  • Construction sites and large rooftops where workers need to cover an expansive area.
  • Maintenance and industrial work that requires technicians to service heating, ventilation, and air conditioning (HVAC) units, solar panels, and other rooftop equipment.
  • Telecommunications applications when installing or repairing antennas and satellite dishes.

7 Straight-up Advantages of Horizontal Lifeline Systems

  1. Adaptable: Designed for easy installation on various roof types, including metal, concrete, and membrane surfaces.
  2. Strong & Durable: Built to withstand harsh weather conditions and frequent use.
  3. Flexible & Mobile: Workers can move smoothly along the length of the line without restrictions.
  4. Continuous Protection: Workers can move safely along the entire length of the system without the need to disconnect and reconnect.
  5. Enhanced Productivity: Workers can perform tasks efficiently without being restricted by frequent attachment adjustments.
  6. Versatile: Up to three workers can be attached to the lifeline system within spans reaching 39 feet (12 meters) between anchor posts.
  7. Safety Compliance: Professionally installed horizontal lifelines meet industry and regulatory standards, ensuring compliance and worker safety.

Roof Anchors Ground Lifeline Safety

Roof anchors provide a secure connection point to horizontal lifelines, enabling workers to move about with confidence. Built from high-strength, corrosion-resistant galvanized steel, they must be designed to withstand a heavy load force applied in any direction. Federal, provincial, and territorial regulations often cite 22 kN (5,000 lbs.)

  1. Permanent Roof Anchors
    Rigid post anchors are designed for fixed, permanent installations, providing a stable attachment point for horizontal lifelines and other personal fall arrest equipment. They can be installed on underlying roof structures made of steel, concrete, or wood, on flat or low-sloped roofs, and on BUR membrane systems, single-ply membranes, modified bitumen, green roofs, and metal roofs.
  2. Mobile Roof Anchors
    Mobile roof anchors provide a portable solution on flat or low-sloped roofs when permanent installation is not feasible. They feature anti-slip counterweight bases connected to a central pedestal with a secure attachment point. Its modular design ensures easy transport and setup, and it does not penetrate the roof.

Reliability Over Drama for Fall Protection

Watching an artist walk a tightrope at the circus or a fair is dramatic and entertaining, but your maintenance workers on the rooftop are not performing for a crowd. They are conducting essential tasks and need a secure and reliable horizontal lifeline and roof anchorage system.

When combined with proper training and regular inspections, lifeline fall protection equipment enables workers to perform their tasks safely and productively.
