Weba) Criteria is based on a new edition of CSA S269.2 (scaffold design and engineering standard). Must have their lowest rung no more than 24 inches above the level on which the scaffold is supported. the tail line is guided, retained, or both, so that it does not become grounded. Have slip-resistant treads on all steps and landings. When canopies are used on suspension scaffolds for falling object protection, the scaffold shall be equipped with additional independent support lines equal in number to the number of points supported, and equivalent in strength to the strength of the suspension ropes. Hook-on or attachable ladders shall be installed as soon as scaffold erection has progressed to a point that permits safe installation and use. Unsafe scaffolding has the potential to result First, it's important to note that there are two strength requirements: 5,000 pounds per employee or maintaining a 2-to-1 safety factor. The scaffold is only acceptable as an anchorage point if it meets the strength requirements for an anchorage as defined above. What are some of the requirements for power-operated suspension scaffold hoists? Are there requirements for suspension ropes?

This provision does not preclude the use of common support members, such as "T" sections, to support abutting planks, or hook on platforms designed to rest on common supports. What materials can be used to increase the working level height of employees on supported scaffolds? Fork-lifts shall not be used to support scaffold platforms unless the entire platform is attached to the fork and the fork-lift is not moved horizontally while the platform is occupied. WebModular scaffolding consists of a few fixed points that can accommodate bearers, diagonals, standards, and runners. Wondering about scaffold guardrail height requirements?
