For Firefighters, Rope Shouldn't Be A 4-Letter Word

While a very practical and efficient fire service tool, the topic of rope for firefighters has been met with a broad range of acceptance (and resistance) within the ranks. However, while most companies have bags of rope on most every apparatus, what surprises me is the lack of its use and the widespread opposition to even taking it out of the compartment when it would be an obvious solution to the tasks at hand.

That being said, I am going to make a significant attempt to get the fire service to rekindle its love and respect for the world of rope in both utility and life-safety settings.

 

Begin the journey

If you recall from your days at recruit school, many types of rope and cord exist for use within the emergency services. We generally decide on the type of rope to be used based on the task it must perform, but all rope work includes a certain amount of danger within the operation.

Rescuers must remember that there are safety rules that must be enforced any time we are working around rope:

The “STOP!” rule – Anyone at any time can yell “STOP!” and all operations cease movement with the rope. It doesn’t mean drop and let go; it means that anyone with rope in their hands holds tight and all movement of the load stops until the problem is identified and addressed so the evolution can continue.

On-scene inspection – Every knot, system and device is checked by look and by feel prior to loading the system. This inspection is done as a cross-check; if the lowering team built the lowering system, someone else inspects the system to confirm its safe use.

Testing before trying – All anchors, systems, harnesses and associated devices within the system will be loaded prior to movement on rope. This loading procedure helps to identify any potential problem areas, such as pinch points for harnesses and packaging, friction areas for rope travel and any potential overloading issues with the systems.

Redundant systems – Along with a main line, a secondary belay line system will be constructed and operated along with the main rope system.

The “no-brainers” – It should go without saying, but I will say it anyway – there is no excuse for anyone smoking, using alcohol or drugs or standing on, dragging or creating friction while rope is in use. The type of operation is dangerous enough, and we shouldn’t be adding to the risk.

 

Selecting a rope

Rope selection is determined by the use; either utility or life safety. An example of utility use would be lifting a tool, hoseline or other object to an elevated area. Any time there is a live (victim) load on a rope, the operation would fall under the life-safety use.

After determining the use, the next selection is the material the rope is constructed from. Natural fiber materials are cost effective, but they contain limited fiber lengths that are woven together to make the rope length. Furthermore, they begin to deteriorate and rot the instant they are cut from the earth. These traits make this type of rope unacceptable for life-safety use.

Synthetic fiber materials do not rot, and are made from continuous filament fibers throughout the entire length of the rope. Moreover, some synthetics can resist heat, float and provide greater flexibility than natural fibers. This makes synthetic fiber rope the material of choice for life safety usage.

Consider the amount of the load and the safety factor for the task being done. Focusing on life-safety use, there are times when a victim and a rescuer may be moving on the same systems. National Fire Protection Association (NFPA) 1983: Standard on Life Safety Rope and Equipment for Emergency Services identifies a safety factor of 15 when working with live loads on rope. In a scenario where a victim and an attendant are being lowered to the ground from above, the attendant (rescuer) is assigned a weight of 300 pounds. The victim is also assigned a weight of 300 pounds to compensate for materials and packaging used in moving the victim to safety, bringing the total weight of the load to 600 pounds. Considering a safety factor of 15 into the equation, a life-safety rope used for a two-person load would need a minimum recommended strength of 9,000 pounds. For our needs, a two-person rescue rope is a minimum of half-inch-diameter nylon static kernmantle rescue rope.
