Collapsed Structure Rescue Class 2007

 

divider line

Overview

During the week of May 7-12, 2007, the NASA Ames Disaster Assistance and Rescue Team conducted its annual advanced Collapsed Structure Rescue class.  It was a six-day ~70-hour class.  This year, 32 students were selected from a large list of applicants who have expressed interest in taking the class. All participants were selected based on experience, knowledge, and skills.

Students came from as far away as North Carolina, Minnesota, and Washington with the majority of them coming from the eight California Urban Search and Rescue (USAR) task forces. The participating rescue specialists are typically considered to be some of the best in the country.

The instructors are past students of the class from all around the country. They volunteer to teach on their own time and dollar because they see the great benefit to the new (fellow rescue specialists) students and themselves. Some of the instructors come back almost every year to participate. They always learn something new from each other during the class.

Day 1 Activities – Using Cutting and Breaching Tools

Chief Bob Dolci introducing the instructors and talking about the week's activities ahead. An instructor talking about the air bag systems Instructor Mac Bala demonstrating about the Oxygen/Acetylene cutting torch Demonstrating how to use a jackhammer correctly Practicing using a hydraulic concrete circular saw
Practicing using a hydraulic concrete chain saw Using the hand pump hydraulic and electric rebar cutting tools Instructor Tommy Timbal teaching how to use a cutting torch Learning to use a jackhammer Instructing on how to use a gas driven concrete circular saw
Learning to use the oxygen/electric cutting probe Doing a plunge cut with the hydraulic concrete chain saw Cutting  an I beam with a cutting torch Using a jackhammer horizontally More practice with the hydraulic concrete cutting saws
Drilling a center hole before breaching the concrete slab Using a jackhammer to breach the wall The various teams practicing breaching concrete slabs Roger Miller leading the review of the days activities

Day 2 Activities – Lifting and Moving Heavy Objects

Learning to crib a concrete slab Learning to lift and crib a concrete slab Lifting the slab with the Phoenix hydraulic tool Learning to lift a concrete block with the Rescue Tech round air bags Ensuring the cribbing stay in place
Lifting and cribbing a car to rescue a victim underneath Rotating a very heavy concrete block Lifting an irregular concrete block Preparing to lift an extremely heavy concrete slab Moving a heavy block of concrete with the Phoenix hydraulic jack
Continuing to lift and crib the concrete slab Moving the heavy concrete block Moving the irregular block of concrete down a slope safely Lifting the slab with the various types of air bags Using the Phoenix tool to move heavy objects
Discussing how to continue the lift Success, the team was able to crawl under and through the slab Now, working to lower the slab back down. It is a tight fit.

Day 3 Activities – Shore Construction

Roger Miller discussing the various tool to assist in building shores Instructing on the use and safety of the various types of nail guns More nail gun safety and usage discussions Instructor Dave Odgers talking about cutting techniques and wedge cutting jigs Finding the plumb of a sloped surface
Building horizontal shores The shores are coming together Working on the shores Another horizontal shore under construction Building a simple vertical shore
Another vertical shore under construction Bob Dolci discussing the pros and cons of this type of shore Building a tall vertical shore for load testing It's starting to come together Almost done

Day 4 Activities – Constructing shores in offset and confined space conditions

Starting to build horizontal shores in more confined spaces Pre-building the components before setting in place The basic first shore is coming together Making it a class two shore Another team building a shore
And yet another team and shore It is starting to get crowded in here One of the completed shores Reviewing the completed shores Bob Dolci conducting the shore review showing how a stokes can be passed through
More shore review This shore is build tough Now building vertical shores Pre-building before installing Using a palm nail gun to build the shore
Some of the instructors reviewing the plans for the final scenario One of the teams showing off their handy work Bob Dolci reviewing a vertical shore The tall vertical shore built the day before ready for load testing The shore failed after about 85 tons of pressure
More shore construction Building a shore in a tighter space The start of building one of the horizontal shores that will be load tested Building a sloped vertical shore The construction of the two horizontal shores to be load tested
The instructors are working hard overseeing the construction Dave Odgers reviewing one of the shore to be tested Load testing a simple class 1 vertical shore. It didn't last long. Starting to load the first test shore Bob Dolci reviewing the characteristics of a loaded shore and what to listen for and observe
The first test shore failed Test shore number two under load. Note the crack in the concrete. Test shore number two failed Building another tall vertical shore to load test Assembling the test shore
This shore took a lot of pressure, but in the end, they all will fail at some load limit

Day 5 Activities – Shore construction at the shore test facility and start of final scenario

The final scenario has started. Breaching a wall to look for victims. Using a search camera to look for victims Building a temporary shore Starting the rescue down the chimney Drilling a starter hole for breaching
Building the more permanent shore Logistics is setup and ready for action Searching the pan caked floors scenario How do we break out of here through these bars? Cleaning the rubble out of the hall way to get to the victim
Building a platform to work from down the chimney Breaching another wall Working in the chimney Shoring up the collapsed ceiling Another ceiling shore going up
This offset shore is coming together

Day 6 Activities – Final Scenario

Cutting through the steel gate Pushing the rubble out of the way Carrying the victim to safety and treatment Finishing up another offset shore Shoring up the cracked walls
Searching the back room after shoring up the walls Drilling a hole through the floor to search for victims Packaging up a victim to carry out to safety Carefully carrying the victim out through the rubble (69kb) Raising a victim out of the chimney using rope and pulleys
The next shift discussing what needs to be done Packaging up another victim Roger Miller leading the review of the weeks activities
