Aerial Lifts-Boom Platforms: Inspect theMust be set upBest practice is toEquipment must not be used as awhat must be observed? Two-point adjustable suspension scaffolds, also known as swing-stage scaffolds, are perhaps the most common type of suspended scaffold. Tip: Almost all incidents that involve scaffold failure would not lead to fatality or serious injury if proper personal fall-arrest systems were in use. (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. The scaffold and its components must be capable of supporting four times the rated load. A worker was on a two-point suspension scaffold that was suspended by cornice hooks at the top of a parapet wall (approximately 42 ft.). This is one more reason for always using fall protection. [, The suspension wire rope must be covered with insulating material at least 4 feet (1.2 m) above the hoist. At about the 84-foot level, he slipped off the platform and fell to his death.

An employee was setting up a two-point suspension scaffold on top of a billboard platform that was 35 feet above the ground. Before allowing workers onto the platform, a good safety practice is to raise the scaffold 3 feet, then lower it and hit the brakes to clear the moisture (see Support). The employer did not control inspection or distribution of this fall protection equipment. 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. [, Scaffolds must be designed by a qualified person, and be constructed and loaded in accordance with that design. This does not preclude the use of systems designed to function as both suspension scaffolds and emergency systems. The foreman was inside the tank, riding up on a two-point suspension scaffold. Fabricated Frame Scaffold Fall Protection. Suddenly, the victim's end of the scaffold dropped to a vertical position, and the victim fell from the scaffold to the ground 60 feet below.
