Question: 1 / 400

What is the minimum height to base ratio for scaffold stability according to some regulations?

2:1

3:1

A minimum height to base ratio of 3:1 for scaffold stability ensures that the scaffold is sufficiently stable to withstand various forces, including wind loads and the weight of workers and materials. This ratio suggests that for every three units of height, there should be at least one unit of base width. This guideline helps to prevent tipping and collapse by establishing a balance between the height of the scaffold and the extent of its base. By adhering to this ratio, construction safety standards aim to minimize the risk of accidents and promote a safer working environment when scaffolding is in use.

The other ratios provided do not align with general regulatory guidelines stressing stability. A higher ratio might theoretically offer increased safety, but 3:1 is widely recognized as the baseline necessary to maintain stability without being excessively conservative.
