Trench Rescue Technician

Course Content
Classroom Portion (8 hours)
The course includes eight hours of intense didactics (classroom).  Designing trench rescue shoring systems is an art that must be based on science. The problem is that most rescuers and most “so called” rescue instructors do not understand the basic science that is involved. Knowing how to calculate the potential soil forces and shoring system strength is paramount to both victim and rescuer safety. Many rescue shoring systems being taught today have been designed without scientific data. In most cases rescuers are left to rely on luck and memory of rote system learning.

The MUSAR Training Foundation’s Trench rescue technician course teaches the participants to apply critical thinking and system analysis skills to design and install rescue shoring systems in trenches and excavations. Students will participate in shoring system testing that will take walers, panels and strong-backs to failure. This destructive testing will provide a new level of understanding of trench shoring and will aid the technicians in developing and installing systems that provide calculated safety margins.
