![]() ![]() Scaffolds may be built in proximity to overhead power lines which can put workers at risk of electrocution. Scaffold screens help to prevent debris from falling on workers below. ![]() They are required on all open sides and areas where workers pass under. Toe boards should be implemented at heights over 10’, toe boards must be implemented with a height of 3½‘’. Proactive steps must be taken to ensure proper protection from falling objects. Many individuals have been injured or killed due to being struck by materials or tools that have fallen from scaffold platforms. Replace rusted, damaged, or weakened partsĬommon falling object hazards include dropping tools, materials, or other objects.Assess the risks to develop, implement and maintain appropriate risk control measures.OSHA standard 1926.451(f)(4) “Any part of a scaffold damaged or weakened such that its strength is less than that required by paragraph (a) of this section shall be immediately repaired or replaced, braced to meet those provisions, or removed from service until repaired.” OSHA standard 1926.451(g)(1) states “Each employee on a scaffold more than 10 feet (3.1 m) above a lower level shall be protected from falling to that lower level.”Įmployees can be severely hurt from the collapse of a scaffold. Guard rails and fall arrest systems must be used when working with scaffolds. If engineering controls and policies fail, a worker losing their footing could result in catastrophe. There is always a risk for falls when working at heights. Prior to use of the scaffold there should be an inspection of the scaffold, this includes replacing rusted and weakened parts.Anchors must be manufacturer approved for use in the anchoring system.Anchorage must be tested prior to the start of work.Sound anchorages include structural members, but do not include standpipes, vents, other piping systems, or electrical conduit.”Īll scaffolding must have proper anchorage in place prior to use and: “Tiebacks shall be secured to a structurally sound anchorage on the building or structure. Lack of proper anchorage can result in a collapse. Some common hazards for all types of scaffolding include:Įmployees can be injured or killed due to a collapse. Scissor lifts are different from aerial lifts because the lifting mechanism moves the work platform straight up and down using crossed beams functioning in a scissor-like fashion. Scissor lifts are mobile supported scaffold work platforms used to safely move workers vertically and to different locations in a variety of industries including construction, retail, entertainment, and manufacturing. Typically supported by ropes on all 4 corners, these are ideal in situations where tall structures are involved. Suspended Scaffolds are platforms suspended by ropes or other non-rigid means from an overhead structure. There are many different types of supported scaffolds. Supported scaffolds are defined as platforms supported by legs, outrigger beams, brackets or similar rigid support. Supported scaffolding is primarily utilized in the construction industry, while suspended scaffolding is more often used for maintenance and cleaning. Scissor Lifts are usually vehicle mounted and are used to reach large heights quickly. Typically used for skyscrapers or when only working on upper levels. Suspended Scaffolding is hung off a building. This is the most common type because it is easier to work from the lower level to the highest. Supported Scaffolding is built from the ground up. Electrocution, due to the proximity of the scaffold to overhead power lines.Being struck by falling tools, work materials, or debris.Collapse of the scaffold, caused by instability or overloading.Falls from elevation with inadequate fall protection.Common hazards associated with scaffolding include: Scissor Lifts used to be classified and covered under Aerial Lifts standards but recently were classified as a type of scaffold. Different types of scaffolding include supported scaffolding, suspended scaffolding and more recently scissor lifts. Scaffolding is described by OSHA as any temporary elevated platform (supported or suspended) and its supporting structure (including points of anchorage), used for supporting employees, materials, etc, at elevated positions. Scaffolding was the 4 th most frequently cited OSHA violation in 2021. ![]()
