Under NFPA 1983, which statements are requirements for Lifelines?

• A. Lifelines are optional; MBS 30 kN; Synthetic fiber
• B. Lifelines must be blue; MBS 20 kN; Cotton fiber
• C. Lifelines universal; MBS 40 kN; Virgin Fiber and Block Creel Construction
• D. Lifelines universal; MBS 50 kN; Virgin fiber only

Answer: (C)

Under NFPA 1983, lifelines are designed to be universal tools that apply across the rescue system, with a specific robust strength and construction to ensure reliability in rope work. The standard requires a minimum breaking strength of 40 kN, and lifelines should be built with virgin fiber using block creel construction. This combination—universal use, a 40 kN rating, and the virgin-fiber, block creel construction—ensures the lifeline is strong, durable, and suitable for all rescuers and scenarios. The other options don’t fit NFPA 1983 because they describe lifelines as optional or impose different material choices, color requirements, or strength levels that don’t align with the standard’s specified criteria.
