The type of scaffold that requires three types of tie-offs is a bricklayers bracket scaffold. This scaffold is specifically designed for masons and bricklayers, offering a supportive structure that allows for the assembly and support of brickwork. It is essential in ensuring the stability of the scaffolding system, especially when working at higher elevations or where heavy loads are involved.

The three types of tie-offs are crucial for maintaining the scaffold's integrity and safety by securing it to the building at multiple points. This enhances the scaffold's resistance to lateral forces, such as wind or the horizontal push from workers and materials being handled. Such robust securing methods are necessary to prevent the scaffold from swaying or collapsing under load.

In contrast, other types of scaffolds, while they may require securement, do not typically mandate as many tie-off points. For example, platform scaffolds, guardrail scaffolds, and frame scaffolds may use fewer tie-offs depending on their design and the specific application. Understanding the distinct characteristics and safety requirements of different scaffolding types is essential for effective and safe construction practices.
