What is the maximum load defined by NFPA 1983 for a one-person load?

The correct answer, which is 1.33 k/N, represents the maximum load defined by the NFPA (National Fire Protection Association) 1983 standard for a one-person load in rope rescue applications. This standard is crucial as it establishes safety parameters for the materials and equipment used in rescue scenarios, ensuring they can support the necessary weight without compromising safety.

When determining loads in rescue operations, it's important to account for not just the weight of the person being rescued, but also for any additional equipment that might be utilized during the rescue process. The choice of 1.33 k/N aligns with the standard's criteria for assessing the strength and reliability of the rescue gear when managing individual loads under varied conditions.

Understanding the significance of this load limit is essential for rescue teams, as it helps in the proper selection and use of rescue gear, ensuring the safety of both the rescuer and the person being rescued. The other options presented do not align with the established NFPA standards for one-person loads, making them unsuitable in this context.
