It is suspected that the cerebellum is the part of the brain that is affected. They were working on a 48-foot-high tank from a two-point suspension scaffold supported by two steel outriggers. The welding current passed through the wire rope supporting the scaffold, and the wire rope separated. The frayed section of welding cable was tied around the metal guardrail of the scaffold. Two of the rope clips were still attached to the end of the rope after the incident. His assistants were outside. =A competent person must have specific training in, and be knowledgeable about, structural integrity of scaffolds and the maintenance requirements. Because the platform is the work area of a suspended scaffold, an inspection requires safety checks of both the platform structure and how the platform is used by the workers. See Personal Fall Arrest Systems in the OSHA Construction eTool. =be plumb and braced to prevent swaying and displacement. Proper Scaffold Construction Mudsills Base plates Crossbraces Access Guardrails All scaffolds must be erected with adequate foundations: Casters Base plates [, Devices whose sole function is to provide emergency escape and rescue may not be used as working platforms. The employee was hospitalized for his injuries. [, 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). Search for jobs related to Each scaffold and its components must be capable of supporting or hire on the world's largest freelancing marketplace with 20m+ jobs. Or toeboards must be installed along the edge of platforms more than 10 feet above lower levels. 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. Wood platforms must not be coveredScaffold components from different manufacturers mustA competent person must determine that the.. Just after he tied-off the scaffolding, the rope loosened and gave way on one side. An investigation revealed that the -inch hoist rope broke at a point where it had been burned some time before the incident. Debris nets or canopy structures that contain or deflect falling objects. [, Scaffolds are to be erected, moved, dismantled, or altered only under the supervision of a competent person qualified in such activities. (Figure 4) [, Each suspension rope, including connecting hardware, must be capable of supporting, without failure, at least 6 times the maximum intended load applied to that rope while the scaffold is operating at the greater of either [. Connecting device (lanyard with shock absorber/retractable lifeline, snap hooks) C. Anti-jerk cord D. Any of the above [, Outrigger beams must be placed perpendicular to their bearing support (usually the face of the building or structure. The employee and the scaffold fell 50 feet to the ground. The plan was to lower the scaffold an additional 20 feet to the main roof. [, Scaffolds shall be altered only under the supervision and direction of a competent person. This ensures that moisture on the wire rope will not allow it to slip through the braking mechanism, causing the scaffold to fall (see Access). The top edge height of toprails on supported scaffolds must be between 36 inches and 45 inches. sunken stomata and transpiration.. a means of access must be provided to a scaffold. 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. The number one scaffold hazard is worker falls. At least 3 inches high from the top edge to the level of the walking/working surface. [, 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. So a 10 foot span (120 inches) cannot deflect more than: 2 inches Although he had brought safety belts and lifelines to the site, this equipment had been left in the company truck. 1. There are two kinds of falling object hazards associated with scaffolds. block is an..Supported scaffold poles, legs, posts, frames, and uprights must be.. = Mud sills must be used in soil, asphalt. 4 A means of access must be provided to a scaffold platform if there is no existing access within ___ feet of the platform 2 Repaired wire rope is acceptable for use on suspended scaffolds Scaffolds and their components shall be capable of supporting without failure at least four times the maximum intended load. =Fall arrest equipment must be utilized. [, Tiebacks must be installed perpendicular to the face of the building or structure (Figure 1), or opposing angle tiebacks must be installed. [, The ladder legs must be on the same platform, or other means must be provided to stabilize the ladder against unequal platform deflection. According to witnesses, the worker slipped out of his safety belt and fell three floors to a concrete walkway and injured his head. 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). One worker managed to hold on, the other two fell with the scaffold, resulting in one worker dying and the other being hospitalized for extensive injuries. [, Set and maintained with the web in a vertical position. [, Outrigger beams must be restrained to prevent movement. The block-and-tackle supporting the system was secured to a vertical steel pipe on top of the tank by a cable, which was fashioned into a loop by U-bolting the dead ends of a piece of wire rope. A cable from this common tie-off was rigged to a block-and-tackle used from ground level to raise and lower the platform. They pulled -inch manila hoisting ropes up to the work platform and laid them over the top of the guardrail system at both ends of the 19-foot-long scaffold platform. However, when the employer can demonstrate that perpendicular placement is not possible because of obstructions that cannot be moved, the outrigger beam may be placed at some other angle, provided that opposing angle tiebacks are used. [, No more than three employees should occupy suspension scaffolds designed for a working load of 750 pounds (non-mandatory). [, Be seated with side-brackets parallel to the frames, and end-brackets at 90 degrees to the frames. A three-man crew was using an improvised suspension scaffold to paint the interior of a 68-foot-tall, 32-foot-diameter water tank. The correct procedures for dealing with those hazards. Employees must be able to safely access any level of a scaffold that is 2 feet above or below an access point. 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. [, The stall load of any scaffold hoist must not exceed 3 times its rated load. The victim was not wearing fall protection while on the scaffold, or while attempting to open the hoistway doors on the scaffold. Scissors lifts are considered by OSHA to be.Personal fall arrest is not required by OSHA. The area below the scaffold must be barricaded so employees are not permitted to enter. Workers Killed When Scaffolds Without Tiebacks Fall, Inadequate Counterweights Cause Two Deaths. Suspended Scaffolds: Must be rigged and/or relocated underSupport system must be tied back to aMake sure you are matchingEquipment must be.. [, Any part of a scaffold that has been damaged or weakened so that it no longer meets OSHA strength requirements must either be repaired, replaced, braced, or removed from service. The work lead on the welder had frayed insulation in one place, and the bare conductor was exposed. [, Be used only to support personnel, unless the scaffold has been designed and built to withstand the tipping forces caused by other loads. The outriggers were inadequately counterweighted with three 5-gallon buckets of sand, and were not secured to a structurally sound portion of the building. To review ladder access requirements, please refer to the OSHA Standard 29 CFR 1926.451(e) or the Supported Scaffolds module. Suspended scaffolds are often made of metal and sometimes used in close proximity to overhead power lines. [, Gasoline-powered hoists may not be used on suspension scaffolds.

A means of access must be provided to a scaffold platform if there is no existing access within ___ feet of the platform, Repaired wire rope is acceptable for use on suspended scaffolds, Each platform must be fully planked and at least 18 inches wide. [, If there is a tail line below the hoist, it must be insulated to prevent contact with the platform. This does not preclude the use of systems designed to function as both suspension scaffolds and emergency systems. [, Scaffolds are to be erected, moved, dismantled, or altered only by experienced and trained employees who have been selected for that work by the competent person. Specific requirements are described below. [, Counterweights must not be removed from an outrigger beam until the scaffold is disassembled. 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. An ideal refrigerator does 150 J of work to remove 560 J as heat from its cold compartment. Cross-braces of the proper length must be used to ensure that the scaffold will remain plumb and rigid. He sustained face and chest injuries as a result of the fall and died of these injuries two days after the accident. Frayed Insulation Causes Arc, Damages Suspension Rope. 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. Three workers were on a two-point suspension scaffold rated at 500 lbs.

[, Wire suspension ropes must not be joined together except through the use of eye splice thimbles connected with shackles or coverplates and bolts. [, On scaffolds where platforms are abutted to create a long platform, each abutted end must rest on a separate support surface (this does not preclude the use of shared support members such as "T" sections, hook-on platforms that rest on common supports, etc.). He was killed. [, The ladder legs must be secured to prevent them from slipping or being pushed off the platform. Tip: When a suspended scaffold sits overnight, water condensation may form on the wire ropes, making them slip through the braking device and cause the scaffold to fall. [, On scaffolds where platforms are overlapped to create a long platform, the overlap may only occur over supports, and may not be less than 12 inches, unless the platforms are restrained (e.g., nailed together) to prevent movement. The employer did not control inspection or distribution of this fall protection equipment. Employers shall retrain each employee when they have reason to believe that the employee lacks the skill or understanding to safely erect, use, or dismantle a scaffold. One employee fell to the ground, and the second employee at the other end was catapulted through an open window, where he was pulled to safety by office workers.

[, Each hoist must be covered with insulated protective covers. Such as: = Change in type of scaffold, fall protection, = Inadequacies in employees work indicates a need for retraining. =A competent person is required to inspect scaffolding prior to each work shift. After approximately two feet, the right-side hoist unit stopped. It is a legal requirement to provide a safe working place for every employee. This poses a risk of electrocution not just to the worker holding the tool, but to everyone who contacts the scaffold. When the brake was released, the three inches of cable left on the drum ran out and the hoist fell, causing the right side of the scaffold to drop. No more than a 12 foot span between hangers. Too much material being stored on the platform. Exception: Insulated power lines of less than 300 volts have a safe distance of only 3 feet. Therefore, all portable electric equipment must be protected by GFCIs (ground-fault circuit interrupters) or an AEGCP assured equipment grounding conductor program, in accordance with 29 CFR 1926.404(b)(1)(i) (see Electrical Incidents: Lack of Ground-Fault Protection in the OSHA Construction eTool). Two employees were sandblasting a 110-foot water tank while working on a two-point suspension scaffold 60-70 feet above the ground. Or between 38 and 48 inches above the work platform for a toprail. No personal fall protection equipment was being used by either worker. 4. . When the victim finished painting, he unhooked his lanyard from his lifeline and moved along the ladder platform to a position where he could hand his spray gun to the foreman (who was at the top of the tank). (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.

Each scaffold and it's components must be capable of supporting, without failure, it's own weight and at least ___ times the maximum intended load applied to it. When the left scaffold rope broke and the scaffold collapsed, one employee was killed and another fell to a nearby roof and broke both arms. (Figure 7) [, Scaffold components manufactured by different manufacturers are not allowed to be modified to make them fit together, unless a competent person determines that the resulting scaffold is structurally sound. As the employees went up in the scaffold, the right side fell to the ground from an elevation of 20 feet. [, Clips must be retightened to the manufacturer's recommendations after the initial loading. The co-worker was left hanging on to the remaining scaffold rope. [, 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. The intent of the standard is for the scaffold and its components .
