Where the scaffold is to be located upon a sidewalk shed, the requirements of Section 3307.6.4.2.2 shall also apply.

No hoisting equipment with a manufacturer's rated capacity greater than 2,000 pounds (907kg) will be located on the scaffold; 3. The scaffold will not be loaded, or designed to be loaded, in excess of 75 pounds per square foot (366.15 kg/m 2 ) (e.g. a light duty scaffold, a medium duty scaffold, or a heavy duty scaffold); 4. The scaffold is less than 40 feet (12 192 mm) in height; 5. Side-arm or end-arm scaffold brackets are used exclusively for the support of workers; and 6. Where the scaffold has a height-to-base ratio (including outriggers supports, if used) of more than four to one (4:1), it is restrained in accordance with Section 3314.9.1.
