divider line

Overview

During the week of April 18-23, 2005, the NASA Ames Disaster Assistance and Rescue Team conducted its annual advanced Collapsed Structure Rescue Class.  It was a six-day ~75-hour class.  This year, 30 students participated in the class. They represented nearly 20 different agencies from eight different states. In addition to the 30 students there was over 20 instructors.

Students came from Illinois, Alabama, Pennsylvania, Delaware, Virginia, North Carolina, Texas, Wisconsin, Washington, and Arizona with the majority of them coming from the eight California US&R task forces. As in the past, the participating rescue specialists were highly skilled and represented their departments with distinction.

Day 1 Activities – Using Cutting and Breaching Tools

Students and instructors sharing the who, what, when and where Chief Dolci briefing course expectations Instructor Dave Odgers discussing breaching Students rotating through metal cutting station Instructor Tom Timbal discussing the fine points of using a torch with one of the students
Student using a rebar cutter Student using a concrete saw in an unstable environment Student using a core saw on the rubble pile Student using a core drill on an eight inch thick concrete slab Student using a 95 pound Stanley jack hammer on a sloped concrete slab
Instructor Tom Timbal showing a student how to cut through a steel plate Student using abrasive disk to cut rebar To bad that it's never this easy in the real world It doesn't always make sense Students will do anything to make the job easier

Day 2 Activities – Lifting and Moving Heavy Objects

Students preparing to lift and flip a five ton block with levers Students lifting a 5 ton block with levers using cribbing Students preparing to flip a 5 ton block 90 degrees using levers Students flipping 5 ton block Flipping a 5 ton block is difficult and dangerous if not done correctly
The last 20 degrees is the hardest Students lifting two concrete blocks using levers Students lifting concrete block above rubble and traversing it ten feet Airbag demonstration Using hydraulic jaws to move concrete rubble
Using hydraulic rams to move concrete rubble Using high pressure airbags to lift concrete blocks Working on a rubble pile with airbags It doesn't look very stable to me Students must be looking for Easter eggs

Day 3 Activities – Shore Construction

Students preplanning for final scenario  (40kb) Dave Odgers making recommendations to Squad Team Leads (35kb) Two is never enough (33kb) Students and instructors (45kb) The fat guy in shorts is Chief Dolci (41kb)
This class goes through 400 lineal feet of 4 Cut station (38kb) Preassembling shores (42kb) By my measurement we are 1/32 of an inch too short - Yeah sure! (29kb) Measure twice, cut once, or was that measure once and cut twice- Darn, it's still too short (43kb)
I think that the cut team cut it too short (30kb) Why do we need a shore in here? (26kb) It must be some kind of weird horizontal shore in a confined space (28kb) It must be a Class III, 3-Strut horizontal shore (24kb) Hmmmm, I wonder if they realize what they are doing? (26kb)
Isn't this diagonal supposed to be on the top? (25kb) Instructors kibitzing  (36kb) Why are they all just standing around? (32kb) David Hammond checking out a shore (39kb) Instructor critiquing shore (31kb)
Students learning about the fine points of shore construction (40kb) Every shore is reviewed  (44kb) So we all agree, this is one weird shore (44kb) Six shores being constructed in six different locations (38kb) Have you noticed that we take a lot of pictures from the back? (42kb)
Is this a laced post shore or a Class III two-post shore? (30kb) They must be proud of their shore (40kb) Donald's nephews? Maybe they're the three stooges  (46kb) I'll look it up (45kb) Is Dolci singing or praying? (28kb)
Darn!! David must have found something wrong with this shore (34kb) Can you tell what's wrong with this shore? (29kb)

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

Ed Cardenas (San Diego Fire) giving a safety talk (36kb) The angle of the dangle is congruent to the reciprocal of the tangent - I think that's what Dolci said. (40kb) Offset Class III Vertical shore in a confined space (44kb) Preparing to build Offset Class III Horizontal shore in shore test trench (42kb) Preparing to build Class III Horizontal shore in shore test trench (36kb)
Airbag is placed between the trench wall and the concrete slab prior to shore construction (29kb) Come on, come on, let's test these shores (50kb) But will it hold a 45-ton force? (35kb) Cut Team (27kb) What are they looking at? (28kb)

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

View of shore test facility (27kb) Preparing to construct shores at the shore test facility (34kb) Building a laced post shore (37kb) More Shore construction (41kb) Still more shore construction (37kb)
Let's stand around and watch the other squads (39kb) 12 foot tall laced post (33kb) Almost done with this one (39kb) This should do it (36kb) Preparing the hydraulics for the test (32kb)
Laced post shore in place and supporting primary load (27kb) Testing the laced post shore (30kb) Can you determine why the shore failed? (29kb) Notice the compression of the wedges and the water squeezed from the sole plate (25kb) What caused the post to fail at this location? (21kb)
Building a Class III Double T Shore (31kb) Shore construction (36kb) I bet it doesn't hold ¼ of the load that an all wood shore does (31kb) Metal posts? (32kb) Never before tested (31kb)
Primary load being placed on shore (29kb) Darn, it didn't even support the primary load of 10 tons. What a shame. (40kb) Yet more shore construction (34kb) What kind of shore is this? (33kb) Will it hold the 45-tons? (32kb)
So what did we learn? (29kb) Getting ready for the final scenario (38kb) It's going to be a lovely night (33kb) Way cool picture (23kb) They built shores in here before (36kb)
This was a little too easy (37kb) Close the door, you're letting too much light in (27kb) Lawrence Livermore team using SARDAR (23kb) Hurry up already (32kb) Like I said, this was too easy (33kb)
We must rest the troops (29kb) You can't see the forest for the trees (41kb) It must be around 11:00 pm. How much longer do we have to go? (24kb) Okay, now we're getting somewhere (28kb) Who put this metal wall here? (23kb)
Carlos, let me feel the baby (36kb)

Day 6 Activities – Final Scenario

Field Emergency Operations Center Dave Odgers (instructor) is the assigned Incident Commander This has to be the toughest part of the whole exercise - It takes 16 hours to go 30 feet What's wrong with this picture? The guy in the white shirt and two of the others are with a Japanese delegation to learn how we do collapsed structure rescue.
Oh Darn! It rained So, does it really take four guys outside the hole to support the two inside? Breach that wall! Look! Mike found a secondary device! SARDAR at work in the rubble pile
And, the purpose of this picture is? But will it fit? Breach wall, build shore, breach floor, make ladder, go down, build shore This town is not big enough for the two of us Nice confined space shore
Camera control room for monitoring the 12 cameras in the collapsed structure Tent for the supporting technologist Tent for the rescue specialist Squad five working the tunnels under the rubble pile The technologist even have their own pillows
Part of the five squad operation - logistics We do rescue rain or shine (26kb) This was the easiest of the five major entry points. Of course they had to do it in the dark. Well at least there are four rescuers in the hole Would you believe that there are two live victims somewhere in the rubble pile?
Hand out the certs and drink a few beers
