Which statement best describes the risk associated with commercial flat lightweight parallel cord configurations during fire operations?

• A. Extremely dangerous
• B. Moderately dangerous
• C. Low risk
• D. No risk

Answer: (A)

In fire operations the materials and arrangements you choose for cordage must withstand heat, abrasion, and dynamic loads. Commercial flat lightweight parallel cords are typically made of lightweight synthetic fibers that can melt, burn, or deteriorate rapidly when exposed to flames, radiant heat, or rough, hot surfaces. Even when several cords run in parallel, that apparent redundancy doesn’t guarantee safety— if one strand weakens or fails, the others can be stressed suddenly and fail as well. The combination of heat damage, rapid load shifts, and the potential for entanglement or snagging creates a scenario where the entire setup can collapse or release abruptly, posing severe injury or fatal risk to responders. That’s why this configuration is considered extremely dangerous.
