Training: Trench rescue shoring
“I often hear “The trench at my rescue incident didn’t look anything like the trenches I have trained in.” The problem stems from a lack of experience and understanding from the instructors and/or the course developers. From the “Book of Z”
• “Every trench you train in should have a cave-in, a void in the wall and a trapped victim (training dummy) buried under the fallen soil.” • “Training in trench simulators (concrete or Conex containers) develops both false expectations and false solutions. Both are counterproductive and produce a false sense of competency.” • “Live trenches are the best teachers. Good instructors simply provide guidance and help keep you safe as you learn from the trenches.” • “The trench rescue shoring “leaning progression” should start at the Operations level with small and medium sized lip shears (both near vertical and low-angled void walls) in straight trenches (8’ deep or less) with two feet of debris on the victim. The next step (technician) should include deep trenches and intersecting trenches with large lip shears, medium wall shears, wedge failures, end-wall failures, slough-ins with overhangs and debris piles that require supplemental shoring.” “The advanced level should include excavations, large wall shears with more than four feet of debris entrapping the victims, angled walls and shoring obstructions (debris piles at the trench walls and equipment) in and around the trench.” Source: Trench Rescue Shoring |
