The workers were wearing the available safety harnesses and lifelines but had not connected the lifelines. Scaffold incidents causing injury or death to workers is often the result of either the planking or support giving way, by the worker slipping, the absence of fall protection, or being struck by a falling object. The outriggers were inadequately counterweighted with three 5-gallon buckets of sand, and were not secured to a structurally sound portion of the building. [, Tiebacks must be equivalent in strength to the suspension ropes and hoisting rope. Therefore, ladder access is not discussed in this module. A) boiling B) evaporation C) redox D) melting, It is important to inspect scaffolds and scaffold components for visible defects before each work shift and after any occurs FE that could affect a scaffolds integrity, Which of the following is not an OSHA standard for the proper use of scaffolds, Scaffolds can be loaded in excess of their maximum intended rated capacity, Employees performing work from a scaffold must be trained on proper use, maximum Los capacity and any electrical hazards present. [, The suspension wire rope must be covered with insulating material at least 4 feet (1.2 m) above the hoist. The employees stopped painting because it started to rain. [, Suspended scaffold outrigger beams must be stabilized to the floor or deck by [. Although he had brought safety belts and lifelines to the site, this equipment had been left in the company truck. Wire cables from each stirrup ran to a common tie-off point. [, Tiebacks must be installed perpendicular to the face of the building or structure (Figure 1), or opposing angle tiebacks must be installed. [, Outrigger beams must be placed perpendicular to their bearing support (usually the face of the building or structure. All scaffolds must be erected with adequate foundations.Concrete. The co-worker stated that he saw the victim fall and jerk upward as the lanyard caught him. The number one scaffold hazard is worker falls. ( 1) Each scaffold and scaffold component, except suspension ropes and guardrail systems, but including footings and anchorage, shall be capable of supporting, without failure, its own weight and at least four times the maximum intended load applied or transmitted to that scaffold or scaffold component. The cornice hooks were not tied back with a secondary tieback system. [, The stall load of any scaffold hoist must not exceed 3 times its rated load. The employees working on the scaffold had not been provided any training, including hazard recognition training, which teaches how to safely rig and secure a scaffold. Neither painter was wearing an approved safety belt and lanyard attached to an independent lifeline. =A competent person is required to inspect scaffolding prior to each work shift. This underlines the importance of inspecting ropes before every workshift. [, Ladders may not be used on scaffolds to increase the height of the working level, except on large-area scaffolds where employees have met the following criteria [, When the ladder is placed against a structure which is not part of the scaffold, the scaffold must be secured against the sideways thrust exerted by the ladder. [, Unless it is designed and installed to support employees and materials without tipping, or has guardrails that block employee access, each end of a platform may not extend over its support more than 12 inches (for platforms 10 feet or shorter in length) or more than 18 inches (for platforms more than 10 feet long). upward and which are moving downward.

Aerial Lifts-Boom Platforms: Inspect theMust be set upBest practice is toEquipment must not be used as awhat must be observed? [, Devices whose sole function is to provide emergency escape and rescue may not be used as working platforms. 3314.3.1.2 Outrigger Scaffolds Specific requirements for one type each of supported scaffold (tubular welded frame) and suspended scaffold (two-point suspension) are included in the sections below. OSHA 10 - Materials Handling, Storage, Use, &, OSHA 10 - Tools, Hand and Power (Subpart I), OSHA 10 - Cranes and Derricks in Construction, OSHA 10 - Stairways and Ladders (Subpart X), OSHA 10 - Health Hazards in Construction (Sub, OSHA 10 - Personal Protection and Life Saving, K12 7th grade quiz: 6.07 Unit Test: Answers a. For other scaffolding guardrail requirements, see 29 CFR 1926.451(g)(4). Each scaffold and its components must be capable of supporting, without failure, its own weight and at least 4 times the maximum intended load applied to it. Unsafe/Unused Fall Arrest Systems Result in Fatalities. Frayed Insulation Causes Arc, Damages Suspension Rope. All support devices must rest on surfaces capable of supporting at least four times the load imposed on them by the scaffold when operating at the rated load of the hoist, or at least one-and-a-half times the load imposed on them by the scaffold at the stall capacity of the hoist, whichever is greater. [, If there is a tail line below the hoist, it must be insulated to prevent contact with the platform. [29 CFR 1926.452(p)(4)]. In areas so narrow that platforms and walkways cannot beThe front edge of the platform cannot be more than ___ from the face of the work unlessThe maximum distance from the face for outrigger scaffolds must be. 4. . [, Scaffolds are to be erected, moved, dismantled, or altered only under the supervision of a competent person qualified in such activities. These incidents can be avoided by compliance with OSHA standards. Hung by ropes or cables connected to stirrups at each end of the platform, they are typically used by window washers on skyscrapers, but play a prominent role in high-rise construction as well. = Top rail to be at 38 inches 45 inches. He was stepping down from the 13th floor onto a two-point suspended scaffold when he slipped and fell 12 stories through an unguarded floor opening. Each suspension rope, including connecting hardware, used on adjustable suspension scaffolds shall be capable of supporting, without failure, at least 6 times the maximum intended load applied or transmitted to that rope with the scaffold operating at either the rated load of the hoist, or 2 (minimum) times the stall load of the hoist, whichever [, Clips are to be inspected and retightened to the manufacturer's recommendations at the start of each subsequent workshift. [, Ends of rails may not extend beyond their terminal posts, unless they do not constitute a projection hazard to employees. The purifier struck the employee and knocked him from the scaffolding. [, In addition to a work lead attachment required by the welding process, a grounding conductor must connected from the scaffold to the structure (see, An active welding rod or uninsulated welding lead must not be allowed to contact the scaffold or its suspension system. Two employees were painting the exterior of a three-story building when one of the two outriggers on their two-point suspension scaffold failed. An employee was setting up a two-point suspension scaffold on top of a billboard platform that was 35 feet above the ground. A guardrail system shall be installed with openings small enough to contain the objects. Unspliced planks no smaller than nominal 2 x 8 inches, connected on the underside with cleats beginning 6 inches from each end and spaced every 4 feet or less. The victim fell five stories to his death. Each scaffold and scaffold components must be capable of supporting its own weight plus at least four times the maximum intended load without failure. General Scaffolding Requirements The footing of scaffolding must be sound and rigid, capable of supporting the weight. Investigation of the incident revealed that the two U-bolts on the loop of cable supporting the block-and-tackle had loosened enough to allow the cable ends to slip through, causing the scaffold to fall. Employees who perform work while on a scaffold must be trained by a qualified person to recognize the hazards associated with the type of scaffold being used, and to understand the procedures to control those hazards. and determine which segments of the cord are moving The type of scaffolding being used is rated as light-duty, or 25 pounds per square foot. Only ___?___ person(s) shall operate an aerial lift. (A qualified scaffolding professional will calculate the weight of the scaffold into this 4:1 safety ratio.) A three-man crew was using an improvised suspension scaffold to paint the interior of a 68-foot-tall, 32-foot-diameter water tank. (Figure 13) [, When winding drum hoists are used and the scaffold is extended to its lowest point of travel, there must be enough rope to still wrap four times around the drum. Between 20 and 30 inches above the work platform for a midrail. [, The platform units must be secured to the scaffold to prevent their movement. on that component, in There are twenty-eight OSHA-approved State Plans, operating state-wide occupational safety and health programs. Each suspension rope, including connecting hardware, used on adjustable suspension scaffolds shall be capable of supporting, without failure, at least 6 times the maximum intended load applied or transmitted to that rope with the scaffold operating at either the rated load of the hoist, or 2 (minimum) times the stall load of the hoist, whichever Because metal frame scaffolds are conductive, power tools, cords, etc., that suffer insulation failure can electrify the entire scaffold. Question: Must the generator frame also support four times the intended load, meaning the generator frame must support a 400,000-pound load? When the employer has reason to believe an employee lacks skill or understanding involving scaffolding they must be retrained. Therefore, assessing personnel abilities is a vital part of scaffold design, erection, maintenance, and use, and should not be overlooked in scaffold inspections. Fall protection consists of either personal fall arrest systems or guardrail systems, and must be provided on any scaffold 10 feet or more above a lower level (two-point scaffolds require both PFAS and guardrail systems). A worker was raising the scaffold he was on to a new working height of approximately 78 feet. building materials, paint roller extensions, scaffold components) that may be handled on them, come closer than 10 feet to the power line. A patient suffers brain damage in an automobile accident. Each scaffold and scaffold component must be capable of supporting its own weight plus at least four times the maximum intended load without failure. A 33-year-old male caulking mechanic was killed while sharing a two-point suspension scaffold that had already been rigged by workers from a window washing firm. [, When other types of hoists are used, the suspension ropes must be long enough to allow the scaffold to travel to the level below without the rope end passing through the hoist, or else the rope end must be provided with means to prevent the end from passing through the hoist. tools, scrap material, chemicals, snow, ice, etc.) (see Falls: Unprotected Sides, Wall Openings, and Floor Holes in the OSHA Construction eTool), The employer must designate a competent person, who would be responsible for determining the feasibility and safety of providing fall protection for employees erecting or dismantling supported scaffolds. [, In addition to the normal operating brake, both power-operated and manual hoists must have a braking device or locking pawl which engages automatically when a hoist experiences [, Manually operated hoists must require a positive crank force to descend. Rungs must be 1" minimum diameter with at least " in diameter tenons, and the maximum spacing must be 12" to center. They lowered the scaffold from the top roof some 16 feet to a small intermediate roof. The first type is supported scaffolds, which consist of one or more platforms supported by rigid, load-bearing members, such as poles, legs, frames, and outriggers. The number one scaffold hazard is worker falls. While the two men were working on the scaffold, their weight caused the outriggers to slip, and the scaffold, rigging, and victims fell to the ground. Instead, the equipment was kept in a common supply bin where the workers could readily obtain it when needed and return it when work was completed. [, Installed with all bearing supports perpendicular to the beam center line. Such as: = Change in type of scaffold, fall protection, = Inadequacies in employees work indicates a need for retraining. Specific requirements are described below. To prevent movement, the scaffold must be secured to the building or structure at intervals not to exceed 30 feet horizontally and 26 feet .

Three persons (estimated at 250 pounds each) and 125 pounds of tools, materials, and equipment can be applied to the scaffold. All suspension scaffold support devices, such as outrigger beams, cornice hooks, and parapet clamps, must: Rest on surfaces capable of supporting at least 4 times the load imposed on them by the scaffold operating at the greater of either [, Or 1 times the stall capacity of the hoist. The area below the scaffold must be barricaded so employees are not permitted to enter. [, Be seated with side-brackets parallel to the frames, and end-brackets at 90 degrees to the frames. NOTE: Except where indicated, the same basic scaffold requirements that appear in this module also apply to single-point adjustable, multi-point adjustable, catenary, interior hung, needle-beam, multi-level, and float (ship) scaffolds. Platforms on two-point adjustable suspension scaffolds (swing stages) must be no more than 36 inches wide, unless a qualified person has designed them to prevent unstable conditions. An "eye" formed by three wire rope clips, which connected the wire rope to the C-hook, failed to hold, and one end of the scaffold came down. There are two kinds of falling object hazards associated with scaffolds. (Figure 17) [. Training shall include [. This was done without inspecting the hoist for sufficient cable length. 2. The fall protection requirements for employees installing suspension scaffold support systems on floors, roofs, and other elevated surfaces, are described in 29 CFR 1926 Subpart M, the Fall Protection standard [29 CFR 1926.451(g)(1)]. [. persons trained in the safe use of these platforms. (Figure 16) [, Nothing that could cause a slip, trip or fall (i.e. Ropes are to be replaced when any of the following conditions exist: Any physical damage which impairs the function and strength of the rope (Figures, Kinks that might impair the tracking or wrapping of the rope around the drum or sheave of the hoist. The superintendent had ordered the scaffold's main support be disassembled before the scaffold was lowered to ground level. Three employees were spray painting a water tower that was 125 ft. high and 30 ft. in diameter. [, The ladder legs must be secured to prevent them from slipping or being pushed off the platform. [, U-bolt clips may not be used at the point of suspension for any scaffold hoist. Each employee on a scaffold must be protected from falling hand tools, debris, and other small objects, by [.

Six other boilermakers had just left a suspension scaffold when it fell about 392 feet along with the foreman, who was killed. NOTE: Except where indicated, these requirements also apply to multi-level, single-point adjustable, multi-point adjustable, interior hung, needle-beam, catenary, and float (ship) scaffolds. =Fall arrest equipment must be utilized. When brackets are used to support cantilevered platforms, they must: Two Workers Killed by Falling Objects While On Scaffolds. Cross-braces of the proper length must be used to ensure that the scaffold will remain plumb and rigid. This particular rig had been used without incident every day for two week preceding this fatal fall. Extreme weather, excessive loads, or damage to structural components can all affect a scaffold's stability. Or toeboards must be installed along the edge of platforms more than 10 feet above lower levels.
