Many building owners, operators, and occupants complain of foul odors emanating from HVAC systems. The objectionable odor is the byproduct of the microbial growth (mold and fungus) that accumulates and develops on wet surfaces of HVAC units, causing foul odors to emanate from affected systems and degrading the IAQ and unit performance. This objectionable odor has been appropriately named the “Dirty Sock” syndrome. Less obvious to the building occupants, but of equal importance, are the physical effects the microbial organisms have on HVAC equip- ment.

  • Opinion on Biological Effects of UV-C Radiation Relevant to Health with Particular Reference to UV-C Lamps
    Health effects of UV-C lamp radiation Final version Scientific Committee on Health, Environmental and Emerging Risks SCHEER Opinion on Biological effects of UV-C radiation relevant to health with particular reference to UV-C lamps The SCHEER adopted this Opinion at its plenary meeting on 2 February 2017 1 Health effects of UV-C lamp radiation Final version ABSTRACT Following a request from the European Commission, the Scientific Committee on Health, Environmental and Emerging Risks (SCHEER) reviewed recent evidence to assess health risks associated with UV-C radiation coming from lamps. At the time of writing the Opinion, few studies were available on exposure to humans under normal conditions of use and there was insufficient data on long-term exposure to UV-C from lamps. These studies report adverse effects to the eye and skin in humans, mainly from accidental acute exposure to high levels of UV radiation from UV-C lamps. Mechanistic studies suggest that there are wavelength-dependent exposure thresholds for UV-C regarding acute adverse effects to human eyes and skin, except for erythema. In contrast, the quantitative estimation of thresholds for long-term health effects could not be derived from currently available data. Due to the mode of action and induced DNA damage similarly to UV-B, UV-C is considered to be carcinogenic to humans. However, currently available data is insufficient for making a quantitative cancer risk assessment of exposure from UV-C lamps. UV-C lamps emitting radiation at wavelengths shorter than 240 nm may produce ozone and need additional risk assessment concerning the exposure of the general public and workers from UV-C lamps to the associated production of ozone.

Mumma Professor of Architectural Engineering _______________________________________ ______________ Richard A. Behr Professor of Architectural Engineering Head of the Architectural Engineering Department iii ABSTRACT Mathematical models of the response of populations of microorganisms exposed to ultraviolet germicidal irradiation (UVGI) are developed that include two-stage response curves and shoulder effects. Models are used to develop a C++ computer program that is capable of predicting the performance of UVGI air disinfection systems. The algorithms are based on models for 1) the intensity field of UVGI lamps, 2) the intensity field due to UVGI reflective enclosures, and 3) the kill rate of microorganisms to UVGI exposure as they pass through the

  • Operating Instructions UVC Germicidal Lamp
    Operating Instructions UVC Germicidal Lamp Model No.: VIO325 Please read these instructions completely before operating this Unit GENERAL PRODUCT DESCRIPTION AND WARNINGS VioUV delivers ultraviolet energy at a wavelength of 254 nanometers. This is a highly effective wavelength against bacteria, mold spores, microbes, viruses, and superbugs. Germicidal ultraviolet rays are harmful to eyes, skin, pets, plants. Safety procedures MUST be implemented to prevent exposure. VioUV should be used as a supplement to your facility’s disinfection cleaning sanitization protocols and not as a substitute to basic procedures. All cabinets and drawers should be open for treatment to allow as much penetration of the UV light possible an have optimum sterilization. Shadows will not be sterilized. Implement and follow a disinfectant protocol. VioUv does not leave any residual substance or harmful by products. No warranty or representations are made by VioUv. Each individual facility is responsible in validating the suitability and protocols for their use. Indoor Use Only: VioUv must be indoors protected in a location that between 40 to 95 degrees Fahrenheit. The UV treatment results achieved are subject to variations in application conditions, it is recommended that culture tests be performed to confirm desired outcomes. Safety procedures MUST be implemented to prevent ultraviolet exposure of people, pets, & plants. Buyer will inspect product after receipt. In the event the product has an issue and claim is not made within 7 days of receipt buyer forfeits and waives the right of warranty. VioUv under no circumstances will be liable for any incidental, consequential or specific damage, loss or expenses arising from the contract for this product, or in connection with the use of, or inability to use, our product for any purposes whatsoever.

  • IMERC Fact Sheet Mercury Use in Lighting
    IMERC Fact Sheet Mercury Use in Lighting Last Update: August 2008 "Mercury Use in Lighting" summarizes the use of mercury in lighting devices, such as fluorescent lamps, automobile headlights, and neon signs. This Fact Sheet covers all the types of lamps that contain mercury in the individual devices; the total amount of mercury in all of the devices that were sold as new in the U.S. in 2001 and 2004; mercury lamp recycling/disposal; and non-mercury alternatives. The information in this Fact Sheet is based on data submitted to the state members of the Interstate Mercury Education and Reduction Clearinghouse (IMERC)1 including Connecticut, Louisiana, Maine, Massachusetts, New Hampshire, New York, Rhode Island, and Vermont. The data is available online through the IMERC Mercury-Added Products Database.2 A number of important caveats must be considered when reviewing the data summarized in this Fact Sheet: The information may not represent the entire universe of mercury-containing lamps sold in the U.S. The IMERC-member states continuously receive new information from mercury-added product manufacturers, and the data presented in this Fact Sheet may underestimate the total amount of mercury sold in this product category. The information summarizes mercury use in lighting sold nationwide since 2001. It does not include mercury-added lamps sold prior to January 1, 2001 or exported outside of the U.S. Reported data includes only mercury that is used in the product, and does not include mercury emitted during mining, manufacturing, or other points in the products' life cycle. Types of Mercury Lamps Mercury is used in a variety of light bulbs.

  • Germicidal Lamp Safety Tips
    Safety Tips for Using Germicidal Lamps What Are Germicidal Lamps? Germicidal lamps emit radiation in the UV-C portion of the ultraviolet (UV) spectrum, which includes wavelengths between 100 and 280 nanometers (nm). The lamps are used in a variety of applications where disinfection is the primary concern, including air and water purification, food and beverage protection, and sterilization of sensitive tools such as medical instruments. Germicidal light destroys the ability of bacteria, viruses, and other pathogens to multiply by deactivating their reproductive capabilities. The average bacteria may be killed in 10 seconds at a distance of 6 inches from the lamp. The wavelength with the greatest effectiveness is 253.7 nm, which defines the germicidal lamp category with optimized wavelength for maximum absorption by nucleic acids. Germicidal lamps that generate energy wavelengths shorter than 250 nm (particularly 185 nm) are very effective in producing ozone, which is required for certain applications to oxidize organic compounds. Hazard and Risks from Germicidal Lamp UV Radiation UV radiation (UVR) used in most germicidal bulbs is harmful to both skin and eyes, and germicidal bulbs should not be used in any fixture or application that was not designed specifically to prevent exposure to humans or animals. UVR is not felt immediately; in fact, the user may not realize the danger until after the exposure has caused damage. Symptoms typically occur 4 to 24 hours after exposure. The effects on skin are of two types: acute and chronic. Acute effects appear within a few hours of exposure, while chronic effects are long-lasting and cumulative and may not appear for years.
