Performing tasks on rooftops and other elevated heights is commonplace for workers in several industries, notably construction, building services maintenance, telecommunications, longshore operations, energy, shipbuilding, and delivering presents on Christmas Eve.
Although the regulatory reach of the Occupational Safety and Health Administration (OSHA) does not extend to the North Pole, Santa Claus is clearly within the agency’s jurisdiction as he goes from rooftop to rooftop on his rounds. The jolly old elf clearly concentrates on the residential sector, where he is likely subject to OSHA regulations for construction. In this industry, fall protection is required when working at a height of six feet or more.
The work-at-height requirement for general industry, which covers most businesses, is four feet. Requirements differ for maritime industries, such as shipyards (five feet) and longshore operations (eight feet). Despite the variations in height requirements for construction and maritime compared to general industry, active and passive OSHA-compliant fall protection systems and equipment can be used across all industries. And if Santa did not travel so fast to make his rounds—it is possible to do this—OSHA might be able to catch up to him.
What is passive and active fall protection?
A passive system is always in place, a stationary structure that does not require the worker to use protective gear or have special training to use it. Prime examples are guardrails, fixed platforms and crossover, skylight screens & covers & railing systems, warning lines (with restrictions), and safety nets.
Active fall protection involves the user being directly attached to fall protection equipment. The worker wears a full-body harness, lanyard, lifeline, and connectors and is supported by an anchorage. There are several required administrative controls, including training and constant equipment inspections.
An active work restraint system limits a worker’s movement when tethered to an anchorage, for example, to within one foot of the roof edge. It is designed to prevent a fall to a lower level. Whereas an active fall arrest system is designed to curtail falls. A worker may go over the edge, but the fall is stopped within a short distance before hitting a lower level or the ground. An active fall arrest system also requires a rescue plan and most facilities have a policy that requires using “the buddy system” or spotters in the event of a fall.
The specific building or environment and the tasks determine the type of fall protection needed.
Primary passive fall protection systems to install.
Guardrails, widely used for flat and low-sloped roofs, provide a physical barrier between workers and fall hazards. Freestanding, modular guardrail systems with pipe-fitted components and recycled PVC counterbalance weights are corrosion-resistant. They are designed for permanent installation and do not penetrate the roof structure. Mobile guardrail sets feature modular sections that are assembled and taken apart easily. They are ideal for contractors and use in the maritime and other industries.
Rooftop Walkways
Roof walkway systems feature anti-slip, non-bounce, self-draining treads to provide a robust, stable base and secure footing as workers traverse the rooftop along designated paths. This also protects the roof from damage due to foot traffic. Walkways with integrated guardrail systems provide an added measure of OSHA-compliant fall protection.
Roof Hatch Kits
For safe egress and ingress to and from the roof, a roof hatch kit attaches to and surrounds the roof hatch with OSHA-compliant guardrails and a self-closing safety gate.
Skylight Fall Protection
OSHA considers a skylight a “hole in the roof” that needs to be protected. Skylight screens are corrosion-resistant galvanized or stainless steel and are affixed to skylights to provide a protective cover without blocking the sunlight. A skylight guardrail surrounds the skylight or roof dome. Screens and guardrails are both OSHA-compliant.

Horizontal Lifelines
An engineered horizontal lifeline system provides continuous fall protection across expansive areas. They can support up to three workers attached to stainless steel cables set between anchorages within a 39-ft. span. Horizontal lifelines protect workers from edges on rooftops and in other work-at-height applications.
Vertical Lifelines
Cable-based lifelines and self-retracting lifelines with davits provide essential and continuous fall protection for ladder use and access to work-at-height spaces.
Anchor Points
Anchors are the foundation of an OSHA-compliant lifeline system. Tieback anchors are installed directly into the roof with various mounting and attachment options. Mobile anchors are used on flat or low-slope roofs and other elevated surfaces. They feature an assembly of four deadweight bases, each with more than 100 suction cups for added grip that connect and support a central pedestal to attach the lifeline system.
