See Personal Fall Arrest Systems in the OSHA Construction eTool. Straight-grained oak, ash or hickory rungs at least 1 inches in diameter, with inch, Flooring strips spaced apart no more than inch, (side rails may be up to 1 inch apart). When conditions warrant, the height of the top edge may exceed the 45-inch height, provided the guardrail system meets all other criteria. This defect and the victim's possible failure to release the parking brake before beginning his descent caused one end of the scaffold to drop. The co-worker stated that he saw the victim fall and jerk upward as the lanyard caught him. Adjustable suspension scaffolds are designed to be raised and lowered while occupied by workers and materials, and must be capable of bearing their load whether stationary or in motion. [, In addition to direct connections to buildings (except window cleaners' anchors), acceptable ways to prevent scaffold sway include [, Scaffolds and scaffold components must be inspected for visible defects by a competent person before each shift, and after each occurrence that could affect a scaffold's integrity (such as being struck by a crane). Therefore, ladder access is not discussed in this module. [, Makeshift devices, such as boxes and barrels, may not be used on top of scaffold platforms to increase the height of the working level. Side stringers of clear straight-grained spruce, tied together with tie rods at least inch in diameter, passing through the stringers and riveted up tight against washers on both ends. (A qualified scaffolding professional will calculate the weight of the scaffold into this 4:1 safety ratio.) Indicate the 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. Two-point suspension scaffolds must be tied or otherwise secured to prevent them from swaying, as determined to be necessary by a competent person. [, Scaffolds must be designed by a qualified person, and be constructed and loaded in accordance with that design. Hazards and Possible Solutions 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). Scissors lifts are considered by OSHA to be.Personal fall arrest is not required by OSHA. [, Provided with stop bolts or shackles at both ends. He was a member of a three-man crew engaged in the abrasive blasting and painting of the interior of a 48-foot-high, 30-foot-diameter steel water tank. [.

These factors introduce the risk of electrocution. Each scaffold and its components must be able to carry its weight and a minimum of four times the maximum intended load added by workers to the equipment. and determine which segments of the cord are moving He fell eleven floors and was killed. 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 employees were not tied off independently, nor was the scaffold equipped with an independent attachment system. = power lines must be maintained (10 minimum). A 53-year-old painting foreman and a 28-year-old painter were killed when their scaffold collapsed. Such retraining is required in at least the following situations [. Suspended scaffolds are often made of metal and sometimes used in close proximity to overhead power lines. He died from the resulting injuries. The right side hoist had only been set up with enough cable to go from the upper roof to the intermediate roof, a total of 16 feet (the total cable length measured 18 feet 5 inches). Two-point adjustable suspension scaffolds, also known as swing-stage scaffolds, are perhaps the most common type of suspended scaffold. (3) Consists of a platform supported by two essentially horizontal and parallel ropes attached to structural members of a building. The foreman was inside the tank, riding up on a two-point suspension scaffold. The trainee fell 18 feet, landed on a stored scaffold pick, and was lucky to sustain only a chipped ankle bone and a bruised calf. After approximately two feet, the right-side hoist unit stopped. He died. Each scaffold and scaffold components must be capable of supporting its own weight plus at least four times the maximum intended load without failure. Correct procedures for erecting, disassembling, etc. An employee was restoring a building's exterior. Therefore, assessing personnel abilities is a vital part of scaffold design, erection, maintenance, and use, and should not be overlooked in scaffold inspections. sunken stomata and transpiration.. a means of access must be provided to a scaffold. [, Guardrails must be surfaced to prevent punctures or lacerations to employees, and to prevent snagging of clothing, which may cause employees to lose their balance.

Two victims and a co-worker were painting the side of a building in San Francisco. They were working on a 48-foot-high tank from a two-point suspension scaffold supported by two steel outriggers. There are two kinds of falling object hazards associated with scaffolds. 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. Tip: Because it may be difficult to determine if a power line is insulated, or what its exact voltage is, the 10 ft. rule should always be applied. The frayed section of welding cable was tied around the metal guardrail of the scaffold. Two employees were sandblasting a 110-foot water tank while working on a two-point suspension scaffold 60-70 feet above the ground. When brackets are used to support cantilevered platforms, they must: Two Workers Killed by Falling Objects While On Scaffolds. Scaffold working platform is the most commonly seen structure at any This underlines the importance of inspecting ropes before every workshift. [, When outrigger beams are not stabilized by bolts or other direct connections to the floor or roof deck, they must instead be secured by tiebacks. He was caught by his belt and lifeline, but after hanging for a few minutes, the lifeline broke and the employee fell to his death. Scaffolds and their components shall be capable of supporting without failure at least four times the maximum intended load.

All scaffolds must be erected with adequate foundations.Concrete. Protecting these workers from scaffold-related incidents can prevent injuries and deaths attributed to falls from scaffolding each year. The second type is suspended scaffolds, which are one or more platforms suspended by ropes or other non-rigid, overhead support. They lowered the scaffold from the top roof some 16 feet to a small intermediate roof. As he was installing a 21-foot-long metal guardrail, it contacted a 34-kilovolt overhead power line located 8 feet from the billboard. When scaffold platforms are more than ___?___ 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 hoist, or similar surface shall be used.

The victim was not using personal fall protection equipment, although it was available and was being used by a second painter. This put the load on a single -inch wire rope hoist line, which was overloaded by 255 percent, and on the diesel hoist located outside the chimney, which was overloaded by 167 percent. When toeboards are used for falling object protection, they must be [. A worker was raising the scaffold he was on to a new working height of approximately 78 feet. 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. Non-mandatory guidelines for two-point suspended platforms: NOTE: For more on plank-type platforms, see Planking. With respect to 1926.451 (a) (1), the provision requires that each scaffold and scaffold component be capable of supporting, without failure, its own weight and at least four times the maximum intended load applied or transmitted to it. An ideal refrigerator does 150 J of work to remove 560 J as heat from its cold compartment. The scaffold consisted of an aluminum ladder used as a platform, and secured to steel "stirrups" made of steel bar stock bent into a box shape and attached to each end of the ladder. It is suspected that the cerebellum is the part of the brain that is affected. This is especially critical with suspended scaffolds, because they often are operated at extreme elevations.
