Thus, in a scenario involving an eccentric load on a cantilevered portion of a platform, the qualified person's design must conform to this criteria. The use of the masonry blocks as what appear to be improvised counterweights indicates that, in the scenario you describe, the scaffold has not been adequately secured against tipping in accordance with §1926.451(c)(1)(iii).
Furthermore, under §1926.451(b)(5), unless designed and installed to support the load without tipping, the cantilevered portion of the platform is prohibited from extending beyond its support more than 12 inches (or 18 inches if the total platform length is more than 10 feet). The use of the blocks in the scenario may indicate that this requirement has also been violated.

Counterweight by: Anonymous
It acts as a counterweight for the masons. The scaffolding can tip over if it's not properly counterweighted, so they hang a block off the connection post or a jack to balance out the weight.
