Aside from being compatible with other components of the system, all equipment should be of sufficient strength to offer appropriate performance under whatever load might be applied, plus offer a sufficient factor of safety above and beyond that. While single body weight loads (one person) are often practices and aspect of litter work (as an …
It doesn’t matter!… Always answer the first question first. Then move to the second… and then, move to the third. What is the purpose? Why is it important? What is needed to fill #1 and #2? So for rope rescue, the last two blogs help with setting this up. I have long lost count of …

When it comes to ensuring safety, there are a number of factors that need to be taken into consideration. During training sessions, the safety standards could be lower than during rescue operations as trainees may not have the same level of experience and expertise. However, this does not mean that training sessions can be conducted …

A systematic approach to rescue equipment selection, care and maintenance can help rescue teams be more effective in their work. By understanding the capabilities and limitations of different types of rescue equipment, rescue teams can choose the right tools for the job at hand. Additionally, proper care and maintenance of rescue equipment can prolong its …
There are four main types of pulleys that are commonly used in technical rope rescue: standard sheave pulleys swivel pulleys prusik minding pulleys knot passing pulleys In addition to these pulleys, there exists a number of other more unique or niche type of multi purpose pulleys. We’ll discuss these in another lesson. Standard sheave pulleys are …
The T-method of analysis allows us to account for the friction in the pulleys and calculate a more accurate mechanical advantage. The efficiency of each pulley is calculated by measuring the difference between its theoretical output force, from our original system analysis, and its actual output force, determined experimentally. The efficiencies are then multiplied together …

Mainline Rescue Systems – A New Course An understanding of mechanical advantage systems — in raising and lower modes — is crucial to all rope rescue technicians. Dealing with Mass and Force is aspects of consequence if not considered during operations. Working with tensioned anchor systems, guying systems, high directionals, load positioning and litter movement …
A rope rescue system is a critical piece of equipment for those in the emergency services industry. It consists of multiple components that link together to allow personnel to safely move an injured person or other load from a hazardous location quickly and efficiently. Ensuring safe operations requires conducting a rigorous system analysis so you …
Okay, so the operation that we did here was a high angle pick-off. And what we do is, we start with our double-long tail bowline. So we approach the victim, we take one of the tails and secure that to their second point of attachment on their harness. At that point we need to unweight …

Again, we are using the CMC Clutch as the lowering and or raising device for these pick-off examples. Once all the lines have been set up, it’s time to secure the rope rescue system. First, attach a prusik hitch to each of the lines about two feet above their ends. Connect the pick-off strap to …
