Guest guest Posted September 29, 2006 Report Share Posted September 29, 2006 For what it is worth.... I understand that the hubbub of this thread is the admissibility of Shoemaker’s testimony. However, what I find appalling is the statement in this brief that....six employees sought benefits after mold was discovered in a wall cavity at their office. If this is true, what BS! Wall cavities are un-occupied interstitial spaces within a structure. Moreover, there are few, if any, structures that don’t have mold spores in their interstitial spaces, and there is plenty of data and research to show that biomass in wall cavities does not significantly affect the occupied space; even if the cavity is black with hyphae and spores. If the mold was present in the occupied space, I would be more sympathetic to the claims of the plaintiffs, because I for one believe inhaled biomass causes harm – some more and some less. But mold in a wall cavity..... What a bunch of bull. There must be more to this case than the brief as written by Courtroom News.

Sharon COURTROOM NEWS <http://www.harrismartin.com/GenerateArticlePDF.cfm?articleid=7522> Date: 26 September 2006 Court Allows Shoemaker Testimony without Frye Hearing ANNAPOLIS, Md. — land’s intermediate appellate court held Sept. 20 that diagnostic and treatment methods used by mold expert Dr. Ritchie Shoemaker were sufficiently accepted that they need not be subject to a Frye hearing for admissibility. Montgomery Mutual Insurance Co. v. Chesson, et al., No. 1270 (Md. Ct. Sp. App.). Ruling in a workers’ compensation case, the land Court of Special Appeals affirmed a trial court order allowing Dr. Shoemaker’s testimony that several church workers sustained sick-building syndrome from workplace exposure to mold. phine Chesson and five other employees of the Baltimore Washington Conference of the United Methodist Church in Columbia, Md., sought benefits after mold was discovered in a wall cavity at their offices in November 2002. The Workers’ Compensation Commission found for the church and its insurer, Montgomery Mutual Insurance Co., on three claims and awarded partial benefits to the three other claimants. The six workers petitioned for consolidation and review by the County Circuit Court and the petition was granted. Montgomery Mutual moved to exclude the testimony of Dr. Shoemaker of Pokomoke, Md., who had examined each claimant and diagnosed sick-building syndrome caused by exposure to mold. Montgomery Mutual argued that Shoemaker’s methods of diagnosing and treating mold exposure are not generally accepted by the scientific community and should be excluded under land’s Frye- analysis (Frye v. United States, 293 F. 1013, 1014 [D.C. Cir. 1923]; v. State, 283 Md. 374, 381 [1978]). The claimants argued that a Frye- hearing was unnecessary as Shoemaker would testify as a treating physician. County Circuit Judge Moylan agreed, and declined to order an admissibility hearing. Judge Moylan explained that Dr. Shoemaker testified that he takes patients’ history, conducts examinations and conducts blood and other tests before making a diagnosis. Those procedures are not uncommon, the judge said. Judge Moylan ruled, according to a transcript, 'we’re talking about a board-certified physician, who has devoted, apparently, in the last five or six years, more than fifty percent of his time to this area of specialty, and I’m satisfied that this is not a Frye- situation,' it’s ‘diagnosis by a medical practitioner, and he, while they have not adopted, or adapted his publications, and things that he has developed; he’s published widely in his field, he’s gone to law school, and consulted, and he’s indicated he’s worked with a number of other doctors in this area; I’m satisfied that he’s qualified to render opinions in this area, and his opinions would be admissible in the things you mentioned that go to their weight, rather than their admissibility.' At trial, the jury ruled for all six appellees, finding they suffered compensable accidental injuries from mold exposure. Montgomery Mutual appealed the verdict and Judge Moylan’s decision to allow Dr. Shoemaker to testify to land’s Court of Special Appeals, which affirmed. 'Because of the nature of the proffered scientific evidence in this case, we reject appellant’s contention that the court erred or abused its discretion by not applying the Frye- test to the testimony of Dr. Shoemaker,' the Court of Special Appeals held. The appellate court quoted extensively from Shoemaker’s deposition testimony about his methods of diagnosis, particularly his treatment of patients suffering from pfisteria in the 1990s, and his method of treating patients believed to have been exposed to biotoxins. Dr. Shoemaker testified that the tests he conducts for hormone and other abnormalities arose 'from basic science published,' the Court of Special Appeals said, quoting Shoemaker. 'In reviewing and comparing the methodologies, it is evident that Dr. Shoemaker employs different tests and strategies to treat the medical conditions of his patients, in general and, appellees, in particular,' the Court of Special Appeals said. 'We agree with the court, however, that there are certain tests that Dr. Shoemaker performs that are not so unorthodox that would warrant subjecting them to a Frye- analysis; e.g., patients fill out forms concerning medical history, the doctor runs several blood tests and performs physical examinations,' the court said. The Court of Special Appeals concluded that while Dr. Shoemaker’s methods may differ in part from many of his colleagues, 't is clear from Dr. Shoemaker’s testimony that these practices have garnered acceptance among peers in this field, which would serve as support for the court’s acceptance of him as an expert and bolster the conclusion that he could render opinions as to the cause of the illnesses sustained by appellees.' 'Significantly, as we noted in Myers,' the Court of Special Appeals held, citing Myers v. Celotex Corp. (88 Md. App. 442, 460 [1991]), cert. denied, Fibreboard Corp. v. Myers, 325 Md. 249 [1992]), 'the finder of fact would have been free to discredit Dr. Shoemaker’s testimony in light of the testimony of other experts regarding their different methods and opposing views. The fact that there were opposing viewpoints based upon other generally accepted methodologies, however, does not lead to the conclusion that Dr. Shoemaker’s testimony should have been excluded.'

Guest guest Posted September 29, 2006 Report Share Posted September 29, 2006 : you stated: " ...and there is plenty of data and research to show that biomass in wall cavities does not significantly affect the occupied space; even if the cavity is black with hyphae and spores... " a few specific cites to the " data and research " from the peer-reviewed literature would be appreciated. you certainly have no shortage of opinion and no hesitation to express same. in this case, however, I believe you're simply wrong. I hear similar arguments all the time: " hey, we don't live in the walls " or " spores in wall cavities can't/don't migrate into the occupied space " . to that I say " horsehockey " . interstitial spaces certainly do communicate with the occupied space. not all such spaces, of course, and not under all conditions. but communicate they do. acting as settling chambers, wall cavities collect fungal spores (and other particulate matter) from both outdoors and indoors throughout the life of the building. this certainty is what makes the use of wall cavity sampling, in my experience, so tenuous and so challenging to interpret (except perhaps on a comparative basis). this form of mass transfer would not occur if infiltration/exfiltration didn't carry those particles through the structure (e.g., the wall assembly). I always enjoy your posts, and generally agree with -- indeed applaud -- your passion and your perspective. but, IMHO " for what it is worth " in this case ain't much.

Guest guest Posted September 29, 2006 Report Share Posted September 29, 2006 - I concur. I have seen projects go both ways... It is also important for everyone to remember that what you may observe, smell, sample, etc. one day - may be completely different the next day, or week, or month for that matter. It will all depend on a plethora of items such as weather, capillary action, HVAC operation, occupant activity, etc. I can also speak from experience with my own home that had major hidden growth within cavities that did indeed affect the indoor air quality of the home, and yes there were very apparent health symptoms that went along with it...

Guest guest Posted September 29, 2006 Report Share Posted September 29, 2006 Mr. Bearg: I did not make a blanket statement and stated " ...that it will be true in all situations. " Get it straight or be quite! Moreover, in my 30+ years of construction, I only recall a handfull of structures that could be represented as " swiss cheese, " assuming you even know that swiss cheese has lots of BIG ROUND HOLES. Moreover, these structure were all slated for demo. The building that is represented in the case write-up which the tread was based is an office of a church. Just how many churches have you experienced that leak like swiss cheese? Moreover, please let me know specifically what your experiences are, and how you determined that there was " considerable air movement from wall cavities into the occupied space? " I believe it is the exception rather than the rule. No modern structure that I am aware of even comes close to your claim!

I found that wool garments are no different. I noticed that some contaminated places give me a huge " hit " but that I could walk away and recover without decontamination. Other places might hit me less, but I would carry the " reaction " with me. This led me to believe that the neurotoxic reaction was to aerosolized mycotoxins and not necessarily inhalation of spores. I tested this by placing a contaminated article in HEPA filters and taking it to my " clean " place. I put it under six layers of blankets and slept on it. I got the usual reaction and removed the article but went back to sleep on the same blankets. The reaction was gone. This convinced me that that spores had not penetrated the filter or blankets and that the toxic gas was truly my primary irritant. This was confirmed by Dr Marinkovich who told me that a housing project in Sweden had recently been identified with sick inhabitants but no spores could be found. Only when the walls were opened up were the colonies found, but they were so tightly sealed in the walls that only the toxic gas could escape. Many places that give me mold hits are strictly VOC hits and not spores. When I leave these areas I do not have to bother with decontamination. - =================================================== Quote Link to comment Share on other sites More sharing options...
Guest guest Posted September 29, 2006 Report Share Posted September 29, 2006 Carl: Agreed. I have no opinion contrary to any of your statements. But let me ask....How many structures do you work on that don’t have problems? How many clients do you have that don’t have problems or health claims? None I presume. You and many of the other mold practitioners only work on problem, symptomatic structures with clients alleging harm/injury. Don’t let this sub-set of all buildings cloud your perspective of construction and/or construction assemblies. I have remodeled and/or demolished a lot of existing structures that had wall/floor cavities which were black with mold, yet no one knew it and it was not affecting the occupants therein. What does this mean....sometimes the biomass in wall cavities does not affect the occupied space or the occupants. It could be that the occupants therein were not hypersensitive, or that the pathway was not well developed, or.... There are many factors. In my opinion, almost all structures with hollow cavity wall systems have some level of biomass in their wall cavities (especially in the southeast), and only a sub-set of these become problematic. However, this sub-set does not support the denigration of construction means, methods, and materials I so often hear from persons who have never built anything in their life. It is unwarranted and without foundation. I never stated that hollow-cavity wall assemblies are constructed so tight that they hold a vacuum. Nor do I support the contention that they leak like swiss cheese. These are but the extremes and we all can find examples to support either side of this spectrum. The norm is somewhere in between. You add-in operation, use, maintenance, and location of the structure, and performance weaknesses begin to become apparent. For example, it is quite apparent that OSB sheeting under a stapled asphalt roof membrane is not appropriate in locations with hurricanes. However, the same assembly performs real well here in the southwest and it is used quite often here because of the lower cost of assembly, thereby making the cost of construction less and the cost of ownership less. We all need to remember that affordable housing is important, VERY important! While everyone may want a well-built, custom home designed by a competent designer that specifies only the best in materials, and assembled by a quality builder that has the skill and takes the time to do it right the first time (like me), few can afford it. So lets be reasonable and practical. Some affordable structures are not going to perform – that is a given. Moldy structures have been around and well-documented since Leviticus was written. Therefore, nothing new or revolutionary. What started this thread was the news brief posted herein that stated that six persons litigated for benefits because of mold present in a wall cavity in their office. I took exception to the foundation of their claim, based on the brief, and suspected that there was more to the claim than presented in the brief because of the lack of a well-developed pathway. I created a firestorm with my comment. Tis not the first time I have been labeled: controversial. In fact, it happened just two weeks ago at a vapor intrusion conference in a room full of good scientists who were bastardizing construction terminology and making overly-broad conclusions regarding the permeability of foundations based on the study of a small sub-set of detached SFDs with basements. I feel this dialog is good. It caused me to think and consider the alternative....and get my head out of the box, if only for a brief period. Regards, -- Geyer, PE, CIH, CSP President KERNTEC Industries, Inc. Bakersfield, California www.kerntecindustries.com , I, too, usually agree with you, but not in this case. I have yet to see a building that was so air tight that you could pull and hold a vacuum (unless designed specifically for it). I have yet to see a building where air pathways were filtered with HEPA media or equivalent. The biomass of mold is not the only component of mold that occupants may be exposed to. Fine particulate and molecular components abound. Mold is not the only micro-organism that amplifies in damp spaces. Bacteria may be more prevalent and of more concern. I have many many clients that when biomass was removed from habitable spaces continued to react until the biomass was also removed from the interstitial spaces. Maybe it wasn't strictly or only the mold, but " something " was there; the removal of which made the difference between habitable and not habitable.

Guest guest Posted September 29, 2006 Report Share Posted September 29, 2006 I speak from 34 years of design/build, mostly residential, in central Florida where some days, but not all we do experience high wind loads. Unfortunately, in our area one need only carry a smoke stick to see what happens around electrical outlets, and window sills. ~Cheryl Quote Link to comment Share on other sites More sharing options...
Guest guest Posted September 30, 2006 Report Share Posted September 30, 2006 , Yes, I agree with you that there should be a exposure assessment on the case for them to establish the causation. I can't comment much on building science since I am not a expert on that. However, I have some thoughts to share with everyone. (1) Have you seen a purple dinosaur? It is much easier to prove that a purple dinosaur exist than the opposite. All you have to do is find "one" (in a little "box" came with a remote control?). However, it is much difficult to prove that they don't exist. The best a scientist can say is that "it was not found during our research/investigation". If the study is extensive, then the possibility of their existence is low (i.g. not significant?). (2) How significant is a "school shooting"? How many percentage of high school students die in a school shooting? Do each one of them die 0.000001% (just a guess %), or some of them die 100%? Is it significant to the general public? Is it significant to the parents who lost their children? Should all school be closed? Should something be done (remediation) to prevent it if you know there is a problem and a possibility that can lead to it? How much MONEY are we going to spend on the prevention program? (3) How much money do we have to remove mold in wall cavity? For leaky or not-so-leaky building? Can we seal that wall cavity in a leaky building if budget is a issue? For sensitive occupants or not-yet-to-be-sensitized occupants? For employee who is likely to sue or not like to sue? For the home of just a mediocre kid or the next Einstein, Mother Theresa, or Dr. King who won't become one if they become asthmatic from mold exposure during childhood (and how are we gonna tell the difference)? I guess it all come down to how we can best (risk assessment?) spend our money. Wei Tang QLAB Geyer wrote: Wayne:I cannot provide you a bibliography. I don't keep them and don't have thetime to develop them, given the amount of literature I review on a monthlybasis. I did a quick, 2-second scan of my Golden Nuggets files on thecomputer, and I cannot find even a non-peer review article on this specificsubject. I develop bibliographies when paid to do it. Pony-up and I willendeavor to do just that. Sorry, I can't fulfill your request. Moreover,most of what I read comes from non-peer-reviewed literature.This said, one of the last case-studies I listened to that is relevant tothis thread was from Dr. Philip Morley regarding a school that had aconstruction defect in the exterior weather barrier that allowed wind-drivenrain to permeated the hollow-cavity wall system of much of the structure onthe wind-ward side of the building. The wall cavities were black with mold(based on his photographs) and after taking over 300 air samples inside theschool, he did not find ANY evidence to suggest that the IAQ was affected bywhat was inside the wall cavities. On the other hand, I listened to a PE atan AIHA conference several years back (I believe it was in San Diego, CA)where this person was "showing" how mold in wall cavities communicates tothe occupied space and "affects" occupants. (There is a reason I use thosewords in quotes.) This person went to a residential, detached SFD that hada construction defect in the exterior weather barrier and had substantialmold in wall cavities. After installing a fan door on the home and inducinga negative pressure differential across the building envelope that simulateda 70-mph steady-state wind pressure, this person collected several airsamples 3-in from electrical wall outlets and "showed" significantcommunication and migration of spores from the wall cavities and into theoccupied space. After the presentation, I asked two simple questions....Howoften does your home experience a 70-mph steady-state wind pressure?, and,How often are you breathing air at the elevation of your electrical outlets?His answer...Never and None. I sat down.Let me also add that I have built several thousand residential units andseveral hundred commercial/institutional buildings since 1975. None ofthese buildings represented swiss cheese wall assemblies, and they certainlydid not leak like some folks on this list allege buildings to leak. I havealso demolished maybe a thousand structures in my time. When I am involvedin a demolition, I always go through building assemblies to observe thearchitecture, assemblage, materials and systems and see what works, whatdoesn't, and the performance of the assemblies. (You should try this. Ilearn a lot from it.) I also paid my way through college replacing (maybe ahundred) rotten bathroom floors in off-campus student housing - it is whatgot me interested in biologicals on construction materials way back in theearly 1980's when no one cared about mold. My air sampling often involvedstacked samplers and I used the University's plant pathology lab toID the molds present. Only when there were obvious holes in walls did Ifind a corresponding bioaerosol in the occupied space. I should also pointout that most of these structures had plaster wall systems - not sheetrock,and they were often painted with an oil-based enamel paint system.Therefore, the type of construction assembly is a significant factoraffecting communication. Bottom line....I know that most folks who opinemold and the performance of building assemblies, don't have squat when iscomes to practical building experience! Moreover their opinions are oftenbased on narrow, limited cases or experiences. I often ask those thatdisagree with my opinions...Just what is your construction experience? Howmany structures have you built? I not saying that I am always correct, andI appreciate being shown where I am wrong. So show me....All this said, I am not saying that there is no communication from a wallcavity to the occupied space. Of course there is. But is it significant?Is it sufficient to cause harm? Is the pathway well-developed? Is itsignificant over time, or periodic of short duration and only under limitedcircumstances and/or events (e.g., the 70-mph wind)? Is it limited tolocalized areas of the structure (e.g., bathrooms and/or kitchens that areoften negatively pressurized), the wind-ward side of the building, or is itsystemic across the building envelope? There are so many factors that needto be considered when evaluating building ventilation rates andinfiltration/exfiltration of wall assemblies and the building envelope.Yes...there are building that leak like swiss cheese, and there are thosethat don't leak at all, and there are a bunch in the middle. To generalizeis to be mistaken.As a bounce-back, please show me peer-reviewed literature that clearlydemonstrates significant communication per this thread. I know there areseveral out there, and, in my opinion, they ALL have faults and they werenot practical or realistic or were very, very limited in scope andapplication. And because I don't keep bibliographies, I cannot cite theseeither. Tis a fault of mine.Bottom line....Yes there is communication. However, based on my experience,it is more often than not, all structures measured equally, insignificant.BTW...I am a bit behind the times.

Guest guest Posted October 5, 2006 Report Share Posted October 5, 2006 Mr. Geyer, I have torn-out a few places and investigated quite a few. I agree that having a background doing demolition work should be a prerequisite for microbial investigations - along with building science. I'm not a P.E. or a C.I.H. I just a sometimes humble contractor that got sick of bad opinions and decided to fix the problem rather than just complain about it. I completely disagree with everything else you said. I am shocked you are a P.E. and a C.I.H. while having those conclusions. I understand someone who only has one of those two certifications not knowing better if they are new to the game. The Baltimore-Washington Conference of the United Methodist Church is near Fort Meade MD and the National Security Agency. It is a one story, brick office building with metal stud walls and paper-faced gypsum board. The insulation was probably R-19 with kraft paper. The building had a history or roof leaks, soil graded improperly on the exterior, pest control problems in the external wall, etc. This could be any office park in America. This particular location is 20 minutes north, northeast of Washington DC not far from I-95. Yes, I saw the debacle late in the process just before the appeals started. I met one of the plaintiffs and she was a mental wreck. Her short term memory could not connect the dots that were plain to everyone else. I suspect the insurance carrier will probably sue the buidling owner/managementcompany to recover some of their losses. Someone did take samples - a C.I.H. He did find the problems. In one instance, remediation was performed and they left the rusted metal tracks and studs below the window. I have dealt with code officials and my uderstanding is you are to replace rusted wall assembly components and they require a construction permit. If the building owner did not take care of business in the beginning, why do you think they would suddenly turn a new leaf? Also, Dr. Shoemaker uses the old-fashioned approach used by environmental docs called an " environmental challenge " . He takes note of physiological differences between exposure to the sick building and non exposure with and without medication to remove microbial toxins or biotoxins. He uses biomarkers like MSH, leptin, MMP9, VEG-F, EPO, some complement proteins from cytokines, etc. He uses a full differential diagnosis. As far as sampling, the methodologies are extremely lacking for accuracy. The qPCR method developed by EPA scientist like Dr. Steve Vespers is really the only way to go. You won't be able to count spores and see if they potential dose for a specific mycotoxin is possible. You will be able to get an " indication " that can be backed-up by a physician's diagnosis if everyone removes the biases and pays attention. I have another client in common with Dr. Shoemaker in the Mid Atlantic region. The whole family was impacted by mold and bacteria from construction defect. The house was synthetic stucco and not a single window was installed even close to proper. Indoor samples had Paecylomyces variotti taken from an andersen sampler (another consultant - CIH). I talked the homeowner into shrink wrapping the house with scaffolding. I theorized the mold was growing on the OSB sheathing and entering the home. The defense attornies were furious and the homeowner got the upper hand. Dr. Shoemaker did the same " environmental challenge " . I can't give you the exact citations but, Wane can: 1. There is a study in Indoor Air (ISIAQ) from 2004 that shows fungal transport through wall assemblies. 2. Texas Tech U did a wonderful study that showed particles under 1 micron from Stachybotrys contained mycotoxins.

Guest guest Posted October 6, 2006 Report Share Posted October 6, 2006 Greg, all: the Texas Tech study was recently cited by another list contributor. here's the Indoor Air cite and the abstract. Indoor Air 2004; 14: 92–104 (vol 14, no 2, April 2004) M. Airaksinen1, J. Kurnitski1, P. Pasanen2, O. Seppnen1 1Laboratory of Heating, Ventilating and Air- Conditioning, Helsinki University of Technology, Helsinki, Finland, 2Department of Environmental Sciences, University of Kuopio, Kuopio, Finland Fungal spore transport through a building structure Abstract The study carried out laboratory measurements with a full-scale timber frame structure to determine penetration of inert particles with size distribution from 0.6 to 4 um and spores of Penicillium and Cladosporium through the structure. Pressure difference over and air leakage through the structure were varied. Measurements at moderate pressure differences resulted in the penetration factors within the range of 0.05–0.2 for inert particles, and indicated also the penetration of fungal spores through the structure. The measurements showed that the penetration was highly dependent on pressure difference over the structure but not on holes in surface boards of the structure. The results show that surface contacts between the frames and mineral wool may have a significant effect on penetration. The penetration was approximately constant within particle size rage of 0.6–2.5 um, but particles with diameter of 4.0 um did not penetrate through the structure at all even at a higher-pressure difference of 20 Pa, except in the case of direct flow-path through the structure. Results have important consequences for practical design showing that penetration of fungal spores through the building envelope is difficult to prevent by sealing. The only effective way to prevent penetration seems to be balancing or pressurizing the building. In cold climates, moisture condensation risk should betaken into account if pressure is higher indoors than outdoors. Determined penetration factors were highly dependent on the pressure difference. Mechanical exhaust ventilation needs a special consideration as de-pressurizing the building may cause health risk if there is hazardous contamination in the building envelope exists. with my compliments, Wane <><><><><><><><><><><> Wane A.
