Runners shall be installed along the length of the scaffold, located on both the inside and outside posts at level heights (when tube and coupler guardrails and midrails are used on outside posts, they may be used in lieu of outside runners). True or False: Once a fall protection device has been inspected by a competent person and deemed safe for use by an employee, it is up to the employee to inspect it regularly and ensure that it still meets OSHA requirements. Each has To ensure scaffolding safety, the scaffold must be built under the supervision of a competent person; someone who has been thoroughly trained on safe work practices when working on scaffoldings.

Additional requirements applicable to specific types of scaffolds. Hardware should be included to fasten the planks into place. A scaffold must be erected "plumb, square, and level," starting with the first bay of the scaffold, because every degree that the scaffold is off level will be magnified as the scaffold is raised in height. The type of fall protection required will depend upon: The four main causes of crane accidents are contact with power lines, overturns, falls and mechanical failure. The cross braces shall be of such length as will automatically square and align vertical members so that the erected scaffold is always plumb, level, and square. Symptoms of silicosis ____________ , so workers should have a chest x-ray to see if there is lung damage. No employee is on any part of the scaffold which extends outward beyond the wheels, casters, or other supports. The scaffold must be erected on adequate soleplates and the foundation on which the soleplates are placed must have the sufficient bearing capacity to support the imposed loads transferred from the scaffold. According to OSHA standard 1926.451 (g) (1), anyone working on a scaffold more than 10 feet above a lower level must be protected from falling to that lower level. A training program to teach proper lifting techniques should cover: A.

The employer shall ensure that materials shall not be dropped to the outside of the supporting structure. When an employee is using stilts on a large area scaffold where a guardrail system is used to provide fall protection, the guardrail system shall be increased in height by an amount equal to the height of the stilts being used by the employee. Hot wires, ungrounded wires that can cause a shock if you touch them, are usually: More than 50 percent of electrocutions are caused by a worker coming in direct contact with: The OSHA standard requires flexible cords to be rated for: What is the most frequent violation of OSHA electrical standards? The poles, legs, or uprights of scaffolds must be plumb, and securely and rigidly braced to prevent swaying and displacement. Hard hats must be worn by all persons erecting, moving, dismantling or using scaffolding. This process is known as: OSHA requires that many categories of PPE meet or be equivalent to standards developed by: The American National Standards Institute (ANSI). Now customize the name of a clipboard to store your clips. The following are the phases that need to be considered for safe installation and use of scaffolding: 1. Float Scaffold. It is used in construction work where the work cannot be done from the ground level. Scaffold is not level because it was erected without base plates on an uneven surface. An employee may wear stilts on a scaffold only if it is a large area scaffold. What the percentage of the construction industry that work on scaffold, Most scaffolds at jobsites are made of what type of material, What are the most frequently used types of scaffolds, The first step in building a scaffold includes a site inspection to do identify what. a. Bearers shall extend beyond the posts and runners, and shall provide full contact with the coupler. Note: Except where . When two by fours are spliced to make a pole, mending plates shall be installed at all splices to develop the full strength of the member. each of the hazards. ", "Form scaffolds and carpenters' bracket scaffolds. When moving platforms to the next level, the existing platform shall be left undisturbed until the new end frames have been set in place and braced prior to receiving the new platforms. Crawling boards shall extend from the roof peak to the eaves when used in connection with roof construction, repair, or maintenance. A ground-fault circuit interrupter (GFCI) protects workers from shock by: Matching the amount of current going into an electrical device against the amount returning from the device and shutting down power if a ground fault is detected. Scaffolds are plumb, square, level and situated on base . Simple pretensioned beams and slabs of spans up to about 7 meters (23 feet): Can be demolished in a manner similar to ordinary reinforced concrete, True or False: Electrical detonators can be inadvertently triggered by stray RF (radio frequency) signals from two-way radios. A. SCAFFOLD BASE MUST BE SET ON AN ADEQUATE SILL OR PAD to prevent slipping or sinking and fixed thereto where required. Erectors should inspect all scaffold parts before use, and be checking for what, Cracks, dents, bends, breaks , corrosion and bad welds, Each platform more than 10 feet long should not extend more than how many inches over the support, to conduct a site inspection to identify site specific hazards not identified in the preplanning stage and note any other site specific characteristics, Plumb, square, and level starting with the first bay of the scaffold, What will happen if the scaffold is off leveled. The three main scaffold types are aerial lifts, supported scaffolds and: suspended scaffolds Because using cranes or derricks to hoist personnel poses a serious risk to the employees being lifted, any cranes and derricks that hoist personnel must: -- Be placed on a firm foundation and be uniformly level within 1 percent of level grade 7.

Independent support lines and suspension ropes shall not be attached to the same points of anchorage. To prevent their displacement, platform units shall be nailed, bolted, or otherwise secured to outriggers. Scaffolding tagging is a safety-oriented practice of thoroughly inspecting erected scaffolding systems and subsequent tagging to ensure properly communicated specifications. The use of safe lifting postures and timing a. Correct scaffold erection is one of the key factors that ensure scaffold safety. Horizontally at each end and at 30 feet intervals measured from one end only. 1926.454 By whitelisting SlideShare on your ad-blocker, you are supporting our community of content creators.

Scaffolding Injuries Approximately 2.3 million construction workers work on scaffolds regularly. Each wire rope used for securing brackets in place or as an anchorage for personal fall arrest systems shall be protected from damage due to contact with edges, corners, protrusions, or other discontinuities of the supporting structure or scaffold components. Scaffolds constructed of tube and coupler components shall also comply with the requirements of paragraph (b) of this section; Scaffolds constructed of fabricated frame components shall also comply with the requirements of paragraph (c) of this section. D. All of the above. sawhorses; others are much more complex, such as the scaffolds erected hundreds of Runners shall be interlocked on straight runs to form continuous lengths, and shall be coupled to each post.
