Final answer:
Suspension ropes on a non-adjustable suspended scaffold must support at least six times the maximum load applied to ensure safety.
Step-by-step explanation:
The question pertains to the safety requirements for suspension ropes on a suspended scaffold. According to safety regulations and engineering standards, suspension ropes on a non-adjustable suspended scaffold must be capable of supporting at least six times the maximum load applied or transmitted to the rope, thereby ensuring a significant safety margin. This safety factor accounts for potential dynamic loads, the age of the materials, wear and tear, and other unforeseen factors that can affect the scaffold's performance and stability.
