Guest guest Posted December 1, 2006 Report Share Posted December 1, 2006 Don: I cannot tell you how to effectively remove cigarette odors.....but I can tell you what does not work. I have had quite a few opportunities to remove/mitigate cigarette odors, and odors from tear gas (which is not a gas but a fume) which is similar. I have heat-treated rooms/apartments/homes.....with little effect. I’ve painted and sealed surfaces....with little effect. I’ve scrubbed, and scrubbed, and cleaned surfaces with all sorts of detergents, soaps, and solvents...with little effect. Usually I have found that the best treatment method seems to be removing and discarding what can be removed, i.e., contaminated surfaces, then sealing the _rap out of what surfaces remain and restoring back to a habitable condition. Methods I have not tried is the ozone and/or peroxide devices. Maybe they work, I don’t know. Sure would like to know other’s opinions. I will never forget two specific projects where the smokers had a lit cigarette going at all times (so I was told), sometimes multiple cigarettes. The walls, doors, cabinets, windows, window frames, etc., were coated with a honey brown layer of sticky cigarette-residue. The smoke trails from the ashtrays were amazing! YUCK! Though we could clean off, and scrap off, a majority of the residue, we could not get rid of the odor via cleaning alone. It was tuff stuff to mitigate. It is also one reason why I will NEVER be a smoker! For what it is worth.... -- Geyer, PE, CIH, CSP President KERNTEC Industries, Inc. Bakersfield, California www.kerntecindustries.com : Will this same procedure work for mild cigarette smoke odors in a house to be purchased by a person with severe MCS? If not, do you, or others, have advice for this situation. I have a client, with severe MCS and autoimmune disease, with a contract to buy a house, the house appears to have no significant defects with respect to iaq, except for the (very) mild cigarette smoke odor.

Guest guest Posted December 3, 2006 Report Share Posted December 3, 2006 Group, I have been refraining from replying to all of you with regard to the use of ozone for odor removal services, but felt it was necessary to finally respond. Here goes...You must have the right kind of ozone generators (UV, not corona discharge)and more than just one or two, (of course, while occupants and pets are out of the building) to do the job effectively. We have used up to 20 pieces of equipment (depending on sq. footage) in order to reach high enough levels of ozone to do the job effectively and we leave them in place overnight for smoke removal. The technician re-enters wearing PPE to turn on the industrial fans already in place, waits about 1/2 hour to 45 min., then uses an ozone meter to determine when it is safe for the occupants to return (no nitrogens, so it is non corrosive and returns to oxygen). We have been doing this very successfully for the last 6 years and real estate agents, hotel management and people with allergies love us! Because we use UV light generated ozone for this purpose, we are not adding nitrogen oxides to the living space. FYI - The equipment we use was also used in a study conducted by Aerotech Laboratories a few years ago where they grew stachy and aspergillus on drywall sections, they sampled pre and post ozoning (took photos of each, with a full report) and it was obvious that the molds were completely oxidized and unable to regenerate. Dr. Rip Rice of the International Ozone Assoc. has established an Air Treatment Task Force and upon his review of the Aerotech study, wrote an article for the IOA newsletter " Ozone News " , Vol. 33, No.3, June, 2005. We are one of many companies associated with Medallion Healthy Homes (in Canada and the US)and follow their methodology to achieve the best results. So, my message to all of you who would like to remove smoke odors (tobacco or post-fire), it can be done much easier, without having to remove everything, SAFELY, using non corrosive equipment and effectively, not to mention faster and cheaper for the customer.

Guest guest Posted December 3, 2006 Report Share Posted December 3, 2006 We also use ozone to get rid of smells in real estate that we mold remediated and the place smells so it won't sell. Sometimes old people or dogs have accidents and there is a urine smell in these units. You get rid of the urine stained carpet or chair and the place still smells. Sometimes a clothes closet smells funky and we ozonate it. The ozone machine works well getting rid of smells. On the other hand I have zero confidence and have never seen any convincing evidence that ozone will disintegrate built up mold in a real world environment.

Guest guest Posted December 4, 2006 Report Share Posted December 4, 2006 “Mold is a plant” HUH???!!! “Yes Stacey, I do sell the Ozone-Lite along with a number of other air purifying devices.” Somehow I am not at all surprised… -S.C. From: iequality [mailto:iequality ] On Behalf Of kengib . Sent: Monday, December 04, 2006 12:14 PM To: iequality Subject: Re: Re: Cigarette Smoke Odors Dear , You are absolutely correct in that ozone will eradicate urine odors as well as most other odors including tobacco, formaldehyde and cooking odors like curry, garlic etc. However let's not overlook the remarkable results of those advanced oxygen substances resulting from Pam's photocatalytic oxidizer. They will not only rid an area of smells but germs as well. The so-called Ozone-Lite [which produces no ozone] is a simple light bulb that can saturate a room with enough safe oxidizers to eliminate all smells but also greatly reduce the population of bacteria and viruses. You are also correct in there doesn't seem to be any creditable evidence that ozone or other oxidizers can rid a surface of mold. After all why should anyone expect so??. Mold is a plant and as such are made up almost entirely of eukaryotic cells which seem resistant to ozone and such oxidizers. However it has been proven that ozone and also the products of photocatalytic oxidation will destroy yeasts such as the Candida Albicans which have deadly hospital implications to those who may be immune suppressed. While yeasts are not mold as such they are fungal and can be deadly to those who may be susceptible. Gibala PS: Yes Stacey, I do sell the Ozone-Lite along with a number of other air purifying devices. ================================ Re: Cigarette Smoke Odors Group, I have been refraining from replying to all of you with regard to the use of ozone for odor removal services, but felt it was necessary to finally respond.

Guest guest Posted December 5, 2006 Report Share Posted December 5, 2006 , We have not had the opportunity to use our equipment post tear gas situations. I am contacting other Medallion Healthy Homes companies to see if any of them have used it for that purpose. It works for skunk odors and other difficult, noxious odors. Since tear gas is carbon based, the ozone will attack it. I would caution however that corona discharge equipment not be used, the nitrogens in conjunction with tear gas chemicals may pose additional problems with air quality. I will let you know if I learn of anyone's experience with a post tear gas situation and what protocol was used.

Guest guest Posted December 5, 2006 Report Share Posted December 5, 2006 Actually, I was recently reading a paper entitled " recent developments in fungal taxonomy " or something like that, and they had a graph as part of the paper that showed the fungi as being more closely related (in DNA terms) to animals (which they described as 'genus animalia') than they were to plants. I thought that was interesting... It explains their tenacity...perhaps.. "Mold is a plant" Quote Link to comment Share on other sites More sharing options...

Guest guest Posted December 5, 2006 Report Share Posted December 5, 2006 Dear Ron, Please introduce yourself... I can not recall having previous discussions with you.. OK... you wish to question the statement regarding Ozone-Lite.... what is the question? By the way I had not received your message #9178 as I am not a regular subscriber to this list... I turn it off for days at a time when I am traveling. So I will apologize if there is anything you feel I have been improper about. In the future please send questions directly to me to my email address. If I don't answer in two weeks feel free to follow up. Sometimes the electrons get lost in their travels. Have you read the Dr. Marsden report from Kansas State?? Please do and then we can discuss further. It's been discussed on the site. Have you researched the literature on the subject using the keywords: <Photocatalysis>, <"Photocatalytic Oxidation">?? Please do and then let's discuss. Have you had the opportunity to review the article "How Long Can You Make an Oxygen Chain?" by J. McKay and S. ? It is an eleven page presentation discussing the the oxidizing ability of H2O2, H2O3, and H2O5. It was published in the Journal of the American Chemical Society. Here's what I understand... Since the discovery of photocatalysis by Fujishimna in 1972 a number of new industries have developed. One is the development of air purification devices including that adapted by NASA to keep the air purified in space capsules. That NASA device today has in my opinion spurred the activity of all producers of PCO purifiers including those produced by EcoQuest, RGF, and Ozone-Lite. No one seems to be able to explain fully how they work to everyone's satisfaction so I shouldn't attempt to discuss the science. Another industry is the use of TiO2 catalysts imbedded in plate glass so window glass can be self cleaning from the outside and generate anti-bacterial properties from the inside. Corning and PPG have already invested millions in this technology. Another is wall coverings where a TiO2 spray can coat a wall and be totally invisible yet react with daylight, fluorescent light or incandescent light depending on the formula of the catalyst and keep a room virtually free of odor and microbials. Table lamps and room decorations with sizable surfaces coated with TiO2 are showing anti-microbial properties when the room is fully illuminated. Floor tiles and ground tiles are being marketed with catalytic surfaces and are being tested in a number of hospitals in Japan. They promise to keep down microbial growth on room floors, hall ways and sidewalks. I have seen reports and videos of side walk surfaces at subway entrances along a main street where the NOx from street trucks is greatly reduced and the structures adjacent to the sidewalks become virtual self cleaning because of the hydrophilic properties of the coatings. The Marsden report says that in test chamber microbials will cease to exist in 24 hours.... The test seems to be applicable to any room such as your bedroom... your kitchen... the butchering shop at the supermarket. The test can be interpreted that exposed surfaces anywhere in a room under treatment will become virtually germ free in 24 hours with the implication that continual treatment will keep the room germ free as long as treatment is applied. Your concern with how hydroxyl radicals can travel a number of feet to kill germs when they are suppose to be so short-lived is a question I can not answer. All I can do is invite you to perform your own test or read the literature. I am aware of Jim Mays' comments and I regard Dr. Mays with the greatest of respect and deference. However his discussions with you were in relation to germicidal UV and the oxidation resulting therefrom. I believe that discussion originated from a report he shared of germicidal UV successes at a hospital in Toronto as reported in an issue of Lancet. And now it appears you are thinking those comments should be applicable to oxidizing products including hydroxyls resulting from photocatalytic action. I disagree. We have two different technologies. The Toronto project was a germicidal UV project. The only oxidizing products coming from that project were those produced from the face of the UV bulb itself as there was no catalyst and therefore no photocatalytic oxidation. The NASA technology is entirely different technology. The NASA Technology creates a family of oxidizers including hydroxyls, hydro peroxides and probably even hydro pentoxides. By the way Wane Baker's ridiculing of my use of the expression O5 is germane to this discussion. While there is no such chemical compound as O5 the expression has been used to represent the family of advanced oxidizers resulting from PCO. However I do not wish to again raise Wane's ire so let us simply call the products what they really are.... advanced oxygen products!! Again how long they can exist I do not know... or what intermediate products may be produced I do not care.... What I care about simply is our space crews are living in air protected by machines using photocatalytic technology and that technology is available today to those who may wish to avail themselves of it. In closing let me suggest you ask our esteemed member from Colorado, Mr. Carl Grimes to perform his own on the spot investigation and visit the NASA Space Foundation at Boulder. He could interview their staff regarding how astronauts are provided uncontaminated air. They should be able to explain to everyone's satisfaction how the technology works. Of course if Carl comes back and reports its all phony that our astronauts carry bottled air to outer space I'll quit the business and feel like a jerk.

Guest guest Posted December 6, 2006 Report Share Posted December 6, 2006 Hi , I am very familiar with the references and the technologies you refer to which is why I asked my question. I am not questioning the efficacy of the various oxidizers produced but rather am questioning the claims made about their distribution. EcoQuest, in its technical information on its RCI Technology states: " Combining high intensity UVX light with a specially developed rare metal hydrophilic coating on an engineered matrix, Radiant Catalytic Ionization (RCI) reduces airborne contaminants, and odors while creating superoxide ions and hydroperoxides. These products of our Advanced Oxidation Process continue working to reduce more odors and VOC's, and to attack microorganisms. " They go on to say " AOP reactants remain effective after leaving the RCI unit as a 'purifying plasma.' " This claim is the basis for my question. May was answering my question when he said " Although there (are) a few relatively complex free radical molecules that have been 'designed,' a small free radical has no more than a fraction of a second existence (nanoseconds, femtoseconds, etc.)and is generally considered as only an intermediate in a chemical reaction. " If this is indeed true, and I have found no evidence to the contrary, then the claim that this AOP exists away from the site of the production of the various oxidizers is blatantly false and should not be made. Since you are so knowledgeable and up to date in this area, please provide scientifically valid studies, references, papers, etc. to support the position that these oxidizers last long enough to exist away from the site where they are produced.
