Guest guest Posted June 25, 2004 Report Share Posted June 25, 2004 What has been your experience in using a UVA light source as a device to make broad area surveys for mold indications, or to determine the boundaries of mold growth areas in situations where the contamination level may be quite low? mickeyander@... Dear Mickey, The ablility to visulaize mold and other fluorescent/lumenescent organic substances can be enhanced with UV-A, making obscure mold growth, for example, more obvious. Using a good quality, high intensity UV-A spotlight can reveal and locate previously unseen spotting on surfaces viewed in white light. These spots, once revealed by the UV lamp, can then be sampled and cultured to identify them, or identified using other scientifically reliable means which may be at the disposal of mold experts, (of which I am not one). My experience is in innovating/promoting the use of these lamps for broad range sanitary inspection applications. As a professional in the cleaning industry since 1983, I recognized a pernacious problem in the industry, that being the inability to locate sources of odor and bacterial contamination in many places such as hotels, hospitals, nursing homes, schools/day care centers, etc. I created the concept of using "blacklight" for sanitary inspection. I saw UV light as the solution to that problem as it has the ability to cause a fluorescent reaction in most body fluids making them plainly visible and, therefore enabling one to clean them up. UV lights it have been commonly used by law enforcement for locating body fluids at crime scenes, so why not in a hospital or a hotel? The concept has grown, as have the miriad of uses people now use it for in sanitation, including mold remediation. I have sold many such lamps for mold inspection so I presume they are being used successfully, as none have been returned. Since the introduction of my first product, which was intended for travelers to inspect the bedding and bathrooms in their accomodations, we have expanded our scope to include UV-C sterilization lamps and UV related technologies, such as photocatalytic oxidation for both air and water purification applications.

Guest guest Posted June 26, 2004 Report Share Posted June 26, 2004 Mickey: I purchased a UVA light for mold investigations/building inspections about a year ago. Although the light does a great job of identifying urine, I have found it to be of little value when it comes to mold. My personal experience with it has been less than satisfactory as it never has been of any help in my finding mold of any kind. I bought the light thinking that it would give me an edge in detecting fungal activity not otherwise detectable or visible but I have been so disappointed with the results that I don't even take it on jobs with me any more. Would love to hear other people's experience with it, maybe I can get some pointers on how to get some use out of mine !!! e Indoor Environmental Testing Inc. > What has been your experience in using a UVA light source as a device to make broad area surveys for mold indications, or to determine the boundaries of mold growth areas in situations where the contamination level may be quite low? mickeyander@c...

Guest guest Posted June 28, 2004 Report Share Posted June 28, 2004 The idea probably first came out of the food industry for detection of nitrogenous wastes (e.g., urine), although many things such as brighteners will also cause fluorescence. see Thrasher, : Detection of Metabolic Products in FDS Bulletin 1. Principles of Food Analysis for Filth, Decomposition and Foreign Matter. US Dept Health & Human Services, Washington, DC. 1981. [there are several good references cited in here that I have including fluoresence of cockroach material] Also, AOAC methods 44.159, 51.106 (1981). I have used UV A and B looking for body fluids in the decon of a contaminated airplane. Also used for mold remediation clearance and in a couple of cases looking for mold. It has a number of inteferences and thus is limited (my opinion). Tony .................................................. "Tony" Havics, CHMM, CIH, PE pH2 5450 N.
