Can Natural Fibers be used for Life Safety?

• A. Yes
• B. No, not acceptable for Life Safety
• C. Only if treated with resin
• D. Only for decorative purposes

Answer: (B)

Life safety rope must meet stringent performance and certification requirements to ensure predictable, reliable support under load in demanding conditions. Natural fibers are inherently variable and tend to absorb moisture, rot, mildew, and be degraded by UV exposure and temperature changes. They creep under load and lose strength over time, making their behavior unpredictable in real emergencies. Because of these weaknesses, natural fibers do not meet the standards and testing required for life-safety applications. Treating them with resin wouldn’t fix the fundamental reliability and aging issues, and would still leave them uncertified for life-safety use. For these reasons, natural fibers are not acceptable for life safety.
