Michigan Residential Builders License Practice Test

A scaffold must be able to support at least how many times the maximum intended load?

1. 2 times

2. 3 times

3. 4 times

4. 5 times

The correct answer is: 4 times

The requirement for scaffolds to support a load that is at least four times the maximum intended load is grounded in safety standards to account for unexpected conditions or load variations during use. This factor of safety ensures that even in scenarios where loads exceed expectations—due to additional materials or worker activity—the scaffold remains stable and secure, significantly reducing the risk of collapse and injury. This safety margin takes into consideration various factors such as dynamic loads when workers are moving, potential movement of materials, and environmental factors like wind. By requiring a scaffold to hold four times the maximum intended load, regulations align with best practices in construction safety, making it a crucial standard for builders and contractors to follow to ensure worker safety.
