Course Overview* Prerequisite is MSA's 2-day Confined Space Entry and Operations Course
MSA’s Confined Space Basic Rope Rigging and Rescue class is designed to teach CS rescue team members the basics of rope theory and use. The predominantly hands-on class begins by covering basic topics fundamental to later training evolutions such as the concepts of utilizing pulleys and rope to create mechanical advantage and system knots that will be utilized in constructing a “Z-Rig” haul system. Once the basics are covered, students will have the construction of a haul system demonstrated for them and then will be asked to participate in a re-creation.
The class terminates in a practice evolution where the students are given a scenario of a downed worker inside a confined space and asked to perform a rope rescue utilizing the tools and techniques that have been demonstrated to them throughout the day.
The 1-day course is comprised of the following:
- Standard-required rescue training / practice requirements and implications for entry rescues
- Considerations for building, equipping, and training a rescue team for hazardous entries to meet ANSI Z117.1–2009 procedural specifications
Building for mechanical advantage:
- Finding other "Height Advantage"
- Water knot and "Wrap 3, Pull 2"
Moving vs. Non-Moving Parts
2:1 & 4:1 “Simple” Mechanical Advantage Systems
