What are the three categories of a load on scaffolding?

The correct answer identifies the three categories of loads on scaffolding as live load, dead load, and environmental load.

Live load refers to the weight of individuals, equipment, or materials that are on the scaffolding at any given time, which can fluctuate as people move and as materials are added or removed.

Dead load, on the other hand, is the permanent weight of the scaffolding itself along with any fixtures and materials that are not intended to move, providing a constant load that must be supported at all times.

Environmental load encompasses additional forces that can act on the scaffolding, such as wind, snow, or rain, which can affect its stability and safety.

Recognizing these categories is crucial for the design and engineering of scaffolding systems, ensuring they can safely support various real-world conditions and usage scenarios. The breakdown of these loads helps in assessing potential risks and making necessary adjustments in scaffolding design and usage to ensure worker safety.
