Final answer:
Light trade scaffolds must be built to support loads not exceeding their weight capacity.
Step-by-step explanation:
In order to ensure the safety and stability of light trade scaffolds, they must be built to support loads not exceeding their weight capacity. The weight capacity of a scaffold depends on various factors such as the materials used and the design of the scaffold. It is important to consult the manufacturer's guidelines or an engineer to determine the specific weight capacity of a light trade scaffold.
