Workers on the mobile scaffold must not attempt to move the scaffold by pulling from one location to another while standing on the platform. If a power system is being used to move the mobile scaffold, the propelling force should be applied directly to the wheels and should not produce a speed in excess of 1 foot per second.ĭuring mobile scaffold movement, no worker can be on any part of the scaffold which extends beyond the wheels, casters, or other supports. When moved, the scaffold must remain on level ground (or within 3 degrees of level) and the area must not have any pits, holes, or obstructions. Only move a mobile scaffold if the workers standing on the platform are aware and ready for the movement to happen. Unlike ladders, mobile scaffolds can be moved while workers are standing on the platform, if the move is conducted safely. The best thing about a mobile scaffold is the versatility and ease of movement. OSHA Standard 1926.452(w)(5) Scaffolds shall be stabilized to prevent tipping during movement. If workers are manually moving the mobile scaffold the force applied should be as close to the base of the scaffold as possible, but definitely not more that 5 feet above the supporting surface. Do not use a forklift, a truck, other motor vehicles, or an add-on motor to propel a mobile scaffold (unless the scaffold in use is specifically designed for such propulsion systems). Power systems used to propel mobile scaffolds must be specifically designed for that use. All locking pins must be engaged before using the scaffold.Īlways follow the manufacturer’s allowable load for the casters, scaffold components and platforms, along with recommended bracing to ensure a rigid and structurally sound scaffold. If outriggers are installed, deploy installed outriggers on both sides of the scaffold. Platforms must not extend outward beyond the base supports of the mobile scaffold unless outrigger frames or equivalent devices are used to ensure stability. OSHA Standard 1926.452(w)(1) Scaffolds shall be braced by cross, horizontal, or diagonal braces, or combination thereof, to prevent racking or collapse of the scaffold and to secure vertical members together laterally so as to automatically square and align the vertical members. Lock scaffold wheels with positive wheel and/or wheel and swivel locks to prevent movement while in use. If the mobile scaffold must be leveled, use screw jacks or the equivalent. Mobile scaffolds in use must be plumb, level, and squared. Keeping the mobile scaffold stable and secure is critically important to worker safety. OSHA Standard 1926.451(h)(1) In addition to wearing hardhats each employee on a scaffold shall be provided with additional protection from falling hand tools, debris, and other small objects through the installation of toeboards, screens, or guardrail systems, or through the addition of debris nets, catch platforms, or canopy structures that contain or deflect the falling objects. Workers on scaffolds must wear hard hats. Heavier objects on the mobile scaffold must be moved away from the edge and secured to prevent falling. To protect employees from falling hand tools, debris, and other small objects, falling object protection is required on or around the scaffold. Before work begins, also assess the work area, the job site conditions, and review the work to be performed.Įven though mobile scaffolds may be smaller than other types of scaffolding systems, falling object protection is still required. Never use a mobile scaffold if it is incomplete, broken, or has missing or ill-fitting parts which need replacement. OSHA General Industry Standard 1910.27(a) Scaffolds used in general industry must meet the requirements of the OSHA Construction Standard 1926, Subpart L (Scaffolds).Ĭonduct a pre-operation inspection to verify that the mobile scaffold is assembled correctly and that all of the scaffold components are functioning properly. OSHA Standard 1926 Subpart L provides the construction industry guidelines for Scaffolds. Narrow frame scaffolds, also known as Baker/Perry style scaffolds, have wheels and are often used as mobile scaffolds with the end frame measuring 3 feet or less in width.Ĭommon hazards that workers must be aware of when using mobile scaffolds include falls from an elevated level, tip-overs, electric shocks, structural failures or collapse, and falling objects. Scaffolds can often be a safer choice than ladders. They are designed to be easily moved and are commonly used for things like painting, plastering, drywall installation, or other jobs where workers must frequently change position. Mobile scaffolds are a type of supported scaffold set on wheels or casters.
