The biggest hazard faced by a commercial roof worker is falling off the roof, which can often lead to permanent injuries as well as death. It is, therefore, necessary to protect these workers from this danger and fall protection should be implemented according to the building’s design.


Guardrails are a type of roof safety system that is passive and after they get installed, the rails provide a physical barricade to prevent the workers from falling off the roof. OSHA calls for these rails to have a top rail that is at least 39 to 45 inches high, a mid rail, as well as a toe board to prevent objects from slipping down the roof and posing a danger to the workers below. A guardrail should be able to endure a minimum weight of 200lb acting in any direction, at any spot along the top edge. These safety rails are generally placed in the hoisting area and the system often relies on the nature of the edge of the roof to be suitable for anchoring the barricades.


As a guardrail ensures that fall hazards are completely eradicated, there is no requirement for a safety monitor or employees to follow the requisites of fall protection.

Generally, guardrails are used along with another system of fall protection, such personal fall arrest system.

In order to use this fall protection system in a safe way, a good training and installation regarding this system and following the requirements of fall protection while anchoring the rails, as well as removing them are important.

Arranging the safety of commercial roofing projects is extremely vital. It is important that the site is visited in order to plan and work out the safety measures and ensure that the workers are provided with all the tools, guidance, and assistance that they require to protect themselves from fall hazards.
