Looking For Advice: Desert Well Rescue

[wagabond]

What is the best method for extraction of injured personnel from a well, with minimal equipment, when there are no anchor points available?

I am currently serving in an extremely arid region of Afghanistan, and have been charged with creating my unit's SOP for rescue from wells, and other similar situations. The wells here are between 0.5m - 2m across, and up to 40+ meters deep (hard for us to tell when they are deeper than that!). They are also, sometimes, covered with thin plywood, and very hard to see at night. Hence the need for a plan.

The main issues arise from the wells' depth, and the fact that there is sometimes nothing at all around them to rig an anchor to. The surroundings are commonly dust, sand, and small scrub brush for hundreds of meters. In addition, any personnel down the well would likely have 100+lbs of gear on them, some of it easily removable, but some very hard in a tight space.

We are light infantry, so the equipment we carry is very limited. We have the ropes, webbing, and belaying/repelling gear, but nothing else very useful besides rucksack frames and Skedco litters (rolled up hard plastic).

I've had a few thoughts, but I am looking for fresh ideas.

Thanks

it you have a backup litter or even a pack you can do a deadman anchor by burying it. not sure it would work for theweight of 2 and all the gear.

For trench rescue etc they do make a tripod that the legs fit around the opening and you tie off in the center with a pulley for raising lowering etc. but for your situation you might have to round up some metal for legs etc that would work for these style wells bolt the center of the tripod together and make it a fold up design. I have seen a similar idea where off of the front bumper is a beam that they use for setting well pumps.

Most of the rescue rigs I've seen involve some sort of tripod set up over the hole upon which to winch without knocking debris down or collapsing the opening. Perhaps three 10-15' aluminum poles do not fit your criteria of "packing light," however.



Do you have a vehicle with a winch available?

 

[wagabond]

Burying a spare litter as a dead man is definately a good idea, thanks Gooseberry. The Tripods are definately way to bulky and heavy for us, although a home made one from local resources is good possibility, if available. Unfortunately, this area of the country is amazingly short on wood, sticks, or metal.

There are some items you can get through supply that can help you. The main part is a anchor system for base radio setups. It is a smaller anchor, generally 3 per set that are structural aluminum. They are light weight and can be quickly hammered into the ground and used as more or less a dead man. Not sure which branch you are in but some marine squads still use them. Come to think of it a buddy of mine in the army has them too. He is in the 10th Mtn. But I can't remember bat #.
The rods are about 30" long and an inch or so thick. I have also seen some that were more like a corkscrew but never found any info on them. I joked saying they looked like the old metal fence posts Germany used for barbed wire in WWI. Hope that helps.

I used to do a lot of stuff with rope rescue classes when I was into caving. Try this link http://www.karstworlds.com/2011/01/free-cave-rescue-manual-life-on-line.html or search single rope technique or cave rescue technique

 

[wagabond]

I think I know the stakes your talking about, Xodius, and I think our commo guys have a few. They may also have some that are a bit smaller, which could be the perfect solution, as long as the area's not too sandy. We could clip right into them with the safety lanyards on our belts.

BigAls book has a good little section on ground anchors, if I can find those stakes.

You might check with Indian Wells Valley Search and Rescue (with the Kern County Sheriff's Department SAR Team) for some ideas, they specialize in rescue/recovery from mine shafts and are considered the best in CA: http://www.kernsheriff.com/Volunteer/SearchRescue/Pages/default.aspx
Dispatch should be able to point you in the right direction, or at least let you talk to the Watch Commander, who should be able to get you in touch with the SAR Coordinator.

I would call a 9lines, request PEDRO. The PJ are all technical rescue certified.

Specifically:
Line 4 you will want 'Bravo' for a hoist and 'Charlie' for extraction equipment
Line 9 designate that the casualty is in a well

The above ideas are great, unfortunately civilian medical/SAR guys don't understand the oz lead to lbs mantra as the funding issues as well as the military guys do. But, fortunately they don't understand the security issue setting up all that fancy equipment poses.

A friend and I also worried about this kind of self rescue but more so in a vertical abandoned mine shaft.

We experimented with a winch line between 2 Jeeps across a (shallow) mine shaft and did a "Tyrolean traverse" on the winch line and went a rope on petzel ascenders.

If you didn't have vehicles you would have to use a deadman as mentioned before or some other anchors. If you didn't have ascenders you could make prusik loops to use as ascenders.

We do something like this for cave rescue - create 2 or more bomber anchors and then focus them in to one place. Tie them together with a rigging plate. Use small pulleys and prusiks to tension them up. It works great when you need to build an anchor that is "floating" in space. We just tried out a variation of this at our training yesterday, so I can give more specifics if anyone is interested. Here is a picture of it in action:

Just a amatureish question- (so don't kill the curious cat!)

Take off helmets

Dig deep hole (5 feet?)

Caabeaner all the chin straps together (will look like big helmet parachute)

Burry helmet to fill with sand. Replace all 5 feet of sand.

Wacky options:

Use figure 8 rescue (or equivalent) that fits 3 barrels.

unload M16's (3), collapse all stocks.
insert barrels into figure 8. Makeshift mini tri pod. Use para cord to or slings to prevent stocks from moving too far apart.

Use carabeaner attached to figure 8 as rope guide.

Tripod for me too....

but thinking of the situation

anchors- you have a squad of heavy guys loaded with gear.....done

Rope you have

ascenders work but are fiddly

Time issues-injured guy


Rope from anchors--- 3 big guys

down well to pulley back up to pull up team

you just made your 200lbs guy only seem like a 100 by the pully

and haul him up

unload the gear seperately then the guy


Nice to haves- caving ladder - self extraction
Tripod as discussed earlier

Think up some ideas- go find a hole and try it !

If you go to page 6-31 of the USArmy Corp of Engineer FOG at this link. This is the field guide used by all FEMA US&R teams.

http://disasterengineer.org/LinkClick.aspx?fileticket=g-0h9OJh3wA=&tabid=57&mid=394

these couple of pages discuss the design loads of pin / pickets tested in various soil types. You dont have to use the log / lumber in the picture since you indicate wood is sparse. you can anchor to the first pin when you have them in series.

if it doesnt work go to www.DISASTERENGINEER.org go to library and lookup the Updated FOG 7 then go to page 6-30
