Guardrails shall be installed along the open sides and ends before releasing the scaffold for use by the employees, other than erection or dismantling crews. Separation of frames can occur in high winds (uplift), or when workers climb endframes, overload the platform, Employees doing overhand bricklaying from a supported scaffold must be protected by a guardrail or personal fall arrest system on all sides except the side where the work is being done. Before erecting a scaffold, the first step is to: a.Perform a site evaluation. d.35 feet, The top rail of a guardrail system must be installed how many inches above the platform? Should he use those planks? Any damaged or weakened component of a scaffold must be repaired or replaced immediately. c.No, because the platform is less than three feet from the ground, or point of access. Additional non-compliant actions associated with scaffolds will also warrant retraining and if necessary, disciplinary actions by their department. Direct access is acceptable when the scaffold is not more than 14 inches (36 cm) horizontally and not more than 24 inches (61 cm) vertically from the other surfaces. Outriggers must be used on narrow frame type scaffolds (i.e. a.5 feet b.20 feet Scaffold planks should extend over their end supports not less than 6 inches nor more than 18 inches. 1.Climb the cross braces. the forklift is not moved horizontally while the platform is occupied. a.15 feet \text { Advertised } 2.

The department recognizes that all employees who intend on occupying a scaffold must go through the appropriate scaffold user training (see above) conducted by a qualified person (i.e. Scaffolds must be plumb, level, and squared. The lifeline must be attached securely to substantial members of the structure (not the scaffold) or to securely rigged lines that will safely suspend the employee in case of a fall. This scaffold is overloaded and planks are strained. The ground where he needs to place the footing is dry but uneven in spots. Access must be provided when the scaffold platforms are more than 2 feet (0.6 m) above or below a point of access. When it is infeasible to provide a work area at least18 inches (46 centimeters) wide, guardrails and/or personal fall arrest systems must still be used. What should be Jayden's next step? Each worker on a suspended scaffold must be protected by a personal fall arresting system attached to an independent lifeline.

Select the correct answer and then click DONE. Only authorized scaffold erectors can erect scaffolds on campus. %PDF-1.4 % In its simplest form, a scaffold is any temporary elevated or suspended work surface used to support workers and/or materials. There are many types of scaffolds, both supported and suspended. This includes (but is not limited to): mudsills, screw jacks, frames, braces, planks, access ladders, brackets, etc. Work shall not be permitted during high winds. Refusing to occupy a scaffold prior to the Competent Person providing documentation indicating that the scaffold has been inspected and deemed safe. Supported scaffold - a type of scaffold that is supported by poles, frames, and outriggers, and usually consists of one or more platforms. This scaffold has no guardrails and is not fully planked. uuid:1f2371a8-90ab-42b0-a1cd-a86bdbf5cef5 \end{array} & \begin{array}{l} front-end loaders and similar pieces of equipment are not used as support scaffold platforms, unless they have been specifically designed by the manufacturer for such use. Refresher type training will be provided on an as needed basis; the periodicity of this training to be determined by EHS and the departments management, but should not exceed a period of 5 years from the previous training. Then this must be inspected when conditions change, such as sunny conditions, warming temperatures, etc. Make sure scaffold components manufactured by different manufacturers are not intermixed, unless they fit together without being forced and the scaffold's structural integrity is maintained. Standard guardrails (e.g., handrail and midrail) and toeboards must be provided for all open sides of the scaffolding that are ten (10) feet or more above the surrounding surfaces. The competent person is responsible for determining the safety and feasibility of installing and using safe means of access, based on site conditions and the type of scaffold involved. Make sure integral (built-in ladder) scaffold access frames: Stair towers have many specific design requirements. Make sure wooden planking is covered with opaque finishes, except that platform edges may be marked for identification. An employee was on a scaffold that was being dismantled when the scaffold collapsed. The end points at each upright shall be no more than 48 inches. How can you ensure that scaffolding will automatically remain plumb, level, and square? Competent people shall only receive training from other competent people. d.Five times, Which would provide a more stable foundation?

Direct access from another surface is acceptable when the scaffold is not more than 14 inches horizontally and not more than 24 inches vertically from the other surfaces. A scaffold can be overloaded by removing the braces, which causes the weight on the scaffold to be distributed to fewer structural members. Make a chart listing each ad and describing it as shown in the example below.

Ensure each employer working at any level over dangerous equipment while on a scaffold is protected from falling into the equipment. Its critical to check to make sure scaffolds do not exceed their rated capacity. Inspecting all scaffold components prior to assembly to insure that components used are of similar material and in good repair before becoming a part of the completed scaffold. Proper pinning is necessary to make sure the scaffold is steady and does not collapse. 1.Use gravel to fill in the uneven spots. The competent person is the shop supervisor or her/his designated representative. \text { discount; pink or silver; } \\ The height of the scaffold in relation to the minimum base width, wind loads, the use of brackets or cantilevered platforms and imposed scaffold load determines the need for stability bracing. Scaffold should not be occupied while moving unless a competent person has determined it is safe to do so. or strike the scaffold with tools, materials, etc. When scaffold platforms are more than 2 feet (0.6 m) above or below a point of access, portable ladders, hook-on ladders, attachable ladders, stair towers (scaffold stairways/towers), stairway-type ladders (such as ladder stands), ramps, walkways, integral prefabricated scaffold access, or direct access from another scaffold, structure, personnel What are integral (built-in) access frames specifically designed for? 4.Ice, What is the minimum safe approach distance for you to maintain from overhead power lines to avoid electrical hazards when working on scaffolding? 3.Maintain three points of contact while on a ladder.

Two tiebacks installed at opposing angles are required when a perpendicular tieback cannot be installed. Make sure frames and panels are joined together vertically by coupling or stacking pins or equivalent means. to prevent falls. All planking or platforms must be overlapped a minimum of twelve (12) inches and secured from movement. To control the risk of a scaffold falling or collapsing, employers must assure that scaffolds are built within OSHA standards relating to strength and structural integrity. b.18 inches d. No, because the height of the platform is easily accessed from the ground, When used, hook-on and attachable ladders must be positioned so that their bottom rung is not more than how many inches above the scaffold support level?

Scaffolding is widely used during construction and renovation activities. Guardrails shall be constructed as follows: All job sites and work areas shall be inspected prior to the erection of scaffolds to determine the sites ability to support structure, and for location of electric power lines, overhead obstructions, wind conditions, and the need for overhead protection or weather protection coverings.
