What is the minimum diameter requirement for G rated rope according to NFPA?

The minimum diameter requirement for G rated rope according to the National Fire Protection Association (NFPA) standards is 11mm. This specification ensures that the rope meets the necessary strength and performance criteria for rescue operations. G rated ropes are typically used for general rescue purposes, and their diameter plays a vital role in determining the load capacity, abrasion resistance, and durability of the rope. By establishing a minimum diameter of 11mm, the NFPA aims to ensure that the ropes used in rescue scenarios can reliably support the weight of both the rescuers and the victims, while also providing the necessary safety margin in various environmental conditions.

The other options represent diameters that are below the established minimum for G rated ropes, which would not meet the safety and functional standards set forth by the NFPA for effective rescue operations.
