According to witnesses, the worker slipped out of his safety belt and fell three floors to a concrete walkway and injured his head. The victim was not using personal fall protection equipment, although it was available and was being used by a second painter. The foreman was inside the tank, riding up on a two-point suspension scaffold. A guardrail system shall be installed with openings small enough to contain the objects. 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. Because metal frame scaffolds are conductive, power tools, cords, etc., that suffer insulation failure can electrify the entire scaffold. This section highlights OSHA standards, preambles to final rules (background to final rules), Federal Register notices (rules, proposed rules), directives (instruction to OSHA staff), and letters of interpretation (official letters of interpretation of the standards) related to scaffolding. Where changes at the worksite present a hazard for which an employee has not previously been trained. This does not preclude the use of systems designed to function as both suspension scaffolds and emergency systems. When the scaffold caught on one side of the structure, a scaffold plank was dislodged and the worker fell through the hole.

Wire cables from each stirrup ran to a common tie-off point. This is especially critical with suspended scaffolds, because they often are operated at extreme elevations. An access ladder or other safe access must be provided. The preferred industry practice at the beginning of a shift is to raise the scaffold 3 feet, hit the brakes, then lower the scaffold and hit the brakes again. [, Counterweights must not be removed from an outrigger beam until the scaffold is disassembled. (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. Two employees were working on a two-point suspension scaffold without safety belts, lifeline, or tiebacks. 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.

At least 4 times the tipping moment imposed by the scaffold when it is operating at the rated load of the hoist. [, When screens and mesh are used, they must extend from the top edge of the guardrail system to the scaffold platform, and along the entire opening between the supports. 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. There are two kinds of falling object hazards associated with scaffolds. [, 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. One painter safely climbed back onto the roof while the other fell approximately 35 feet to his death. Therefore, ladder access is not discussed in this module.
