![]() ![]() In this standard, OSHA says: “Guardrail systems shall be installed along all open sides and ends of platforms. Guardrail requirements are listed in the OSHA 1926.451(g)(4) standard. What Are the OSHA Specifications for Guardrails? Toe boards shall be at least 3.5” (8.9 cm) in height from top edge to floor level, and be capable of withstanding a force of 50 lbs. Toe boards shall be provided when employees below could be exposed to falling objects such as tools. If wire-rope guardrail systems are utilized, highly visible tape or flags must be placed every 6’ to increase visibility. Midrails are halfway between the top rail and walking/working surface and must stand up against a downward and outward directional force of at least 150 lbs. Guardrails should be inspected per the manufacturer’s specifications or a qualified person’s requirements. in any direction per OSHA 1910.29(b)(3)(4)(5). A guardrail consists of a top rail 42” + or – 3” no less than 39”, mid-rail at 21” and toe board 3.5” high. Guardrails need to have a minimum breaking strength of 200 lbs. To add more layers of protection, screens, mesh, or balusters could be utilized in tandem with the guardrails. any workplace with an accessible rooftop.Īlso Read: What is the difference between fall protection and fall prevention.landscaping and work areas in natural settings, and.Guardrails are used in every industry and can be seen in: The standard guardrail system features a top rail, intermediate (or mid) rail, and support posts. ![]() ![]() Guardrails serve as passive fall protection in the Hierarchy of Fall Protection. Falls from as little as 4’ to 6’ can cause long-term time away from work, and in the most severe cases, death, which means all open-sided floors and platforms 6’ or more in height must be guarded. businesses over $125 billion annually.įalls are the leading cause of death in the construction industry, and most fatalities happen when employees fall from open-sided floors and through floor openings. Also, there are 5.7 million non-fatal workplace injuries, which cost U.S. Additionally, guard rails or a combination of guard rails and toe boards may be required if risk of falls are identified such as to internal service gaps or if working above the height of the principle top guard rail.Why Is It Necessary to Have Fall Prevention Measures?Īccording to OSHA (Occupational Safety and Health Administration) Publication 2056, there are nearly 6,000 workplace fatalities in the United States and 50,000 deaths due to workplace-related illnesses each year. The principle (top) guard rail must therefore be between 950mm and approximately 1260mm above the decked platform if 225mm scaffold boards are used as toe boards.Īll board lifts or sections of board lifts must be protected with double guard rails and toe boards (to prevent risks of falls to persons or materials). An intermediate guard rail must then be connected below the principle (top) guard rail so that the gap between the two guard rails and the gap between the intermediate guard rails and any toe board used does not exceed 470mm. Guard rails must be installed so that the principle (top) guard rail height is measured at a minimum of 950mm to the top of the tube on both outer and end faces, this is measured from the decking forming the platform to the top of the guard rail. On a straight run of independent scaffold, it is permissible to fix the end guard rail with a single coupler at the outer standard position above the outer façade guard rail with the inside of the same tube fixed to the inner standard with a right angle coupler. Cantilevered end guard rails fixed at one end are unsafe and must not be used. The guard rail tubes should be connected at a minimum of two points to prevent downwards and outwards movement of the guard rail. The guard rails are fixed to the outer (façade) and end face (return) of the scaffold, the guard rail tubes are fixed to each standard of the scaffold structure using right angle coupler. The guard rails are generally constructed by fixing scaffold tubes horizontally to the inside of the scaffold standards (uprights) to create the temporary edge protection. ![]() Guard rails are required to form temporary edge protection to scaffolding structures at both board lifts working lifts and none working lifts used during the construction of the scaffolding structure. Guard rails are required to all scaffolding lifts (other than foot lifts) to prevent falls. ![]()
