    Default Mass Decon

    Ok our department has just started looking hard at our procedures for mass deconin the past year or so. So far this is what they have figured for a quick inital set up can somebody help me with any improvements that could be made to this plan.

    The quick line is set up between two engine companies with two or three ladders drapped across each with a 1 3/4" preconnect drapped over (wide fog) and connectd by hose chains. each engine also has two side discharges with TFT nozzles attached to them and on a wide fog as well. Also running over head is a section of 2 1/2" hose for water supply. This is all done with hydrant pressure if possible. Also at the entrance and exit there is supposed to be a firefighter in proper ppe with a booster line to do pre-wash and final flush. We have discussed adding ladder pipes into it, but so far this is our main plan. We have a inflatable tent that FEMA gave us after a big WMD excercise at Ft. Knox last year and that so far is added into the decon line as a holding area to keep victims warm and secluded from the rest of people.

    I would appreciate any comments that anyone has.

    Thanks,

    Cory Adkins

    The Massachusetts Department of Fire Services Hazmat Training division recently came up with a program called RAM decon (Rapid Access Mass Decon). We recently trained in this procedure. Two pumpers and an aerial are used in the drill.

    The two pumpers are placed parallel to each other with the pump panels facing outwards. Fog nozzles are connected to the side discharges and a handline is taken off of each rig. One line is taken around the rear of one pumper, the other is taken around the front. The aerial is set up with a ladder pipe and fog nozzle. The aerial is extended to the tip is right over the space set up between the two pumpers. A guide rope is set up for the people who are to be decontaminated to follow. When the water is flowing, it creates a 360 degree shower area so people can be rapidly decontaminated. There is so much water being flowed in the shower that contamination from runoff is minimal. The day we did the drill, I volunteered to walk throught the shower area. I changed out of my uniform and into a t-shirt and gym shorts. Damn that water was cold... but it was hot day and it felt great!

    I think we should give some thought to the long term contamination effects of some of the agents that we might be washing into the storm drains and into our drinking water supply. Dilution may not be the solution.

    It only takes one molecule with some of this stuff, and some of the virus and bacteria multiply in amazing ways and would benefit from all the washwater. We might need to plan on using some of the new warfare agent neutralizing chemicals like the Navy QAC applied with a new CAFS system. There is no run off with the foamed decon and you can see what, who, and where the stuff is.

    The way we looked into that was that contamination is a second priority your first companies on scene generally aren't going to have that kind of equipment on hand to be able to succesfully control the contamination. At least in my neck of the woods our feeling is let it run in send the Sewer District ahead of the flow and plug the sewers. Or if possible wait for our response truck to bring more equipment but in our area that can be a while.

    Thanks for the input.... Kinda made me laugh when I looked at the last date that this was posted... 9-11-01

    For the benefit of those on this board, please tell us exactly what substances will contaminate a water supply with only "one molecule" and which virus and bacteria multiply in amazing ways and would benefit from all the washwater". I am anxiously awaiting your answer. And pleae don't give me any of that "classified info" stuff, because it isn't.

    The one thing that makes me crazy in the NBC Terrorism area is misinformation and disinformation. Many of the people talking about WMD incidents have little to no idea what they are talking about. cfire is one of those people. If you read his post and then look at his profile, his post was a scare tactic that was a self serving plug for foam...the very product he claims to be a manufacturer of.

    I had no doubt that he would not respond to me. There is no agent in the world that could contaminate a water supply of any size with just one molecule. There is no agent in the world that can "multiply in amazing ways and would benefit from all the washwater."

    You guys were almost scammed by a person attempting to personally benefit from an exaggerated claim of WMD terrorism.

    We conducted a WMD awareness class for all our personnel about two years ago. As a result, we initiated a mass casualty decon procedure almost identical to the one Captain Gonzo described, which was "copied" from a demonstration we saw at the IAFC Hazmat Conference in Towson, Md., put on by Deputy Chief Gary Warren of the Baltimore County Fire Department. We added some equipment to our first due apparatus, such as disposable tyvek coveralls for post decon dressing of victims, as well as ziplock bags for their valuables. Clothing would go in large plastic bags, which are carried on the HMRV.

    Also, we agree with George Wendt's comments. Our County Health Department fully supports rapid decon with LARGE amounts of water, and considers environmental impact from runoff in these situations to be virtually non-existant. Knowledge of the characteristics of the substances involved is of utmost importance when dealing with them. After the events of the recent past, we don't need hype or fabricated information to confuse this issue.

    All we can do to succeed with a response to this threat is to LEARN about what we are up against, and PLAN to deal with the threat accordingly. Stay Safe!

    Looks like you are making some good progress. If I may add my 2 cents. First, the decon operations sound good, but they will all take time to set up. Are you putting your people in harms way? If you first set up a ladderpipe or deck gun operation with a small tip to achieve maximum reach/distance and direct your victims via PA to go to the 'shower' to start the decon process, you may buy your crews time and distance from contaminated people, to safely set up your decon corridor. Do not become part of the problem. Remember that everything that you collect is possible evidence from a crime scene. When bagging clothes, if you have the capability to seperate into a clear zip lock bag, ID, wallet, purse, jewelry, valuables and place that baggie inside the clear clothing bag so it is visable, it might help with identification and retrieval of personal items should the threat be downgraded and not require the destruction of what was thought to be contaminated goods. (Customer service!) Modesty, good luck getting people to strip down in public. What can you do to protect the victims from the media and the environment? Preplan for your target hazards.

    It only takes one carcinogen molecule to effect a sensitive cell and you got problems.
    So it might be best to try to keep as much contamination to a minimum. Or you might find a product that can neutralize some of it. But guys like you wouldn't believe it.

    So let me get this straight. If you drop one "Carcinogen" molecule into a multi-million gallon water supply, you have what is tantamount to bio-terrorism? Are you for real?

    "Carcinogen" is a broad class term for a multitude of materials that can cause or suspect to cause cancer in some living cells. It is not a bioterrorism agent. Following your logic, if an individual with skin cancer washed their hands and the cancer cells went into the waste water stream, there should be a widespead outbreak of cancer in the area served by that water system. Let's see, how often has that happened? Never!

    You really should bone up on your weapons of mass destruction training before you spout off here.

    HaHa! I think it would be funny to hear how a guy like you tries to figure out how you got cancer or where you got infected from a terrorist or any other source of bio agent.

    I appologize to the group,for lowering myself to Georges level. I am not selling anything.

    I want to make a final comment about the run-off problem with bio-agents. Dilution may not be the solution.
    Microbe multipy rapidly, and can live for very long periods of time to haunt us later.
    Consider how red tide starts, very small to very large.
    We shouldn't just wash bio agents off and expect it to disappear in the large volumes of water. The water does not kill the microbes, it spreads them. The microbes need food and water. This can include infecting the mosquitos that use the run-off. We must consider decontaminating more than just the people. I do not try to mis-inform,confuse or scare people, We are simply not prepared.

    You can keep telling me to grow up, but I will not sit here and let this guy spout off things that simply are not true.

    By way of background, I am presently assigned to a law enforcement task force responding to possible WMD calls on a daily basis. The task force includes members from every conceivable discipline from fire to medical to public health to even animal control. Obviously, these have all (over 80 since Fri) have been negative. However, the training is still there for an actual incident. I know what I am talking about.

    There is not one shred of documentation that has been brought to the table by any of our members (most of them extremely well educated and qualified) that remotely suggests that agents commonly found in bio terrorism incidents can affect a large water supply in microscopic qunatities. If it is out there, I ask him to quote sources and educate us all, including me.

    The Red Tide is not a bio-terrorism agent. It is an aquatic plant that is naturally occurring. There is no evidence that a microscopic amount of cancer cells can cause a cancer cluster if it is in a water supply. Mosquitoes cannot carry a bio-terrorism agent, they would be dead instantly if it came into contact with a small amount.

    My "level" as always, is facts. If there is documentable evidence to suggest otherwise, someone please enlighten me.

    George, have you ever heard the controversy about how the West Nile Virus, that is carried by mosquitos, got started? or that many other biological and virul agents could be used to effect our health and our agriculture industries? Do you have any idea how many organisms it would take to start foot and mouth or mad cow in water? Did you ever wonder why the shoes were decontaminated at the airports when GB had their outbreak? If you think all is well and that I shouldn't try to talk about this or try to do something about it then seeya, wouldn't wanabeya.

    What are your credentials that make you an expert on bio-terrorism and hazmat decon procedures?

    By the way...your playground attitude is getting really boring!

    I don't claim to be an expert on bio-terrorism, all I'm trying to do is raise awarness that it might be dangerouse to use large volumes of unrecoverable water to wash away bacteria, virus, fungi and other micro-organisms. I know emergency responders first priority is to get the situation under control, but I've seen very little attention toward the final cleanup.
    I have been working with the Naval Surface Warfare Center to complete a CRADA agreement to develop a warfare agent and pesticide decontamination application system. All the test are finished and the patens are issued to the Navy. Hopfully the QAC will be available in the near future.

    As for the "playground" bs, that is for George who sends iritating messages to my email and that seems to be the level he understands best..sorry if it offended you.
