Polycyclic aromatic hydrocarbons (PAHs) are the first type of chemicals that were ever discovered to cause cancer in humans. They are found in cigarette smoke, in barbecued and smoked foods, in automobile and Diesel engine exhaust, fireplace smoke, and many other common things that people are exposed to. Analyzing for PAHs in the environment is important in identifying potential sources of cancer exposure and eliminating these as risks.

    The role that water plays in our existence is well understood. Without it, most living things will rapidly wither and die. Equally catastrophic of course, are the consequences of too much water. Not only to living things, in terms of widespread flooding, but also in terms of damage to machinery and equipment from exposure to water.

    A tornado can cause catastrophic and extensive damage to all types of structures. For some, the damage requires a total rebuild. However, for the homes and buildings that are salvaged after a tornado, a detailed assessment by a qualified structural engineer is needed to determine the extent of structural damage, the repairability of the structure, and to assist with other repair recommendations related to the building envelope and required building code upgrades.

    The tiny pinhole in the pipe elbow probably took more than twenty years to form and cause a leak, a day or two to be discovered, and less than an hour to be repaired. This recent claim involving corrosion of a pipe elbow on a home heating oil tank resulted in a very minor release of a few gallons of heating oil to the surrounding surface soil. The insured acted appropriately, the release was quickly investigated and repaired. Based on the size of the tank and volume of the release, state regulations did not apply; however, local regulators became concerned over the possibility of impact to shallow groundwater in the area. Although the shallow aquifer was not considered a source of drinking water, it was used extensively for irrigation. Furthermore, the property owner soon began to notice petroleum like odors inside the home/office necessitating relocation for a couple of days. After the repair of the leak, the situation was completely resolved in a few weeks with the excavation and removal of impacted soil from beneath a patio and a portion of the building adjoining the point of release. Fortunately, the release was discovered early, quickly repaired, and the volume of the spill was not sufficient to impact groundwater, which could have easily transported contaminants and associated vapors well beyond the boundaries of the insured's property.

    Both large-scale catastrophe-induced losses and small-scale single event losses have the potential to impact employees, individuals, insurance personnel, general contracting restoration firms and associated property loss. In addition to the actual water-loss event, secondary losses can become equally as devastating depending on pre-existing and/or event-related building conditions, and the role the insured's take as part of required catastrophe restoration activities. During the water loss event, all project related information and environmental data generated is an integral part of the decision making process that may be disclosed at various stages to inform all the various "parties" involved with the project. All in all, a well-executed restoration project can minimize common delays and expenses of an ill-conceived and managed project.

    Sectors of the construction industry are reporting resurgence and growth in 2013. Single and multi-family housing, commercial, institutional and public works construction is predicted to increase up to 28% in some areas. This is good news for the industry and the economy but the increase in construction activity has historically led to an increase in construction accidents.

    In the course of an arson investigation one of the standard procedures is, when possible, to collect the clothing of arson suspects and have them tested for ignitable liquids. The hypothesis being that if the clothing tests positive for the same ignitable liquids that are found in the fire debris, it is good circumstantial evidence to place the suspect at the scene with an ignitable liquid.

    A growing concern in the insurance sector is soot and smoke damage claims due to wildfires. Some of these fires can affect properties hund reds of miles downwind, causing the potential number of claims to be astronomical. Besides the known risks for respiratory and other health problems, smoke, soot, and char can cause physical damage ranging from settled ash to property damage.

    3/24/2015 · OSHA
    Every year, approximately 3,600 workers are permanently disabled, and on average, one worker per day is killed, as a result of electrical incidents in the workplace.* To prevent these types of electrical injuries and deaths, building owners and managers should apply the safeguards included in NFPA 70E, the standard utilized by the Occupational Safety & Health Administration (OSHA) for building electrical assessments. OSHA utilizes the National Fire Protection Association's (NFPA) 70E Standard for Electrical Safety in the Workplace to provide improved safety procedures for workers through proper warning labels, restricted access notification, personnel training and personal protective equipment (PPE). OSHA compliance will minimize workplace injuries, accidents, illnesses, equipment damage, production losses, and legal costs, which are all avoidable and unnecessary factors in any business.

    Historically, fires and automobile accidents have been the primary types of property and casualty claims that presented a potential avenues of for subrogation. However, with the increased costs of mitigating the extent of water damage and reducing the potential for mold growth, claims involving large water losses have become another important area with subrogation potential.

    Mechanical ventilation systems have evolved from passive gravity vents (circa 1900) by adding modifications to improve comfort, occupant health, and energy efficiency. Early on, the maintenance of the system basically related to making sure the furnace was on and the windows would open. If you were lucky the school might have draft deflectors on the windows so the wind would not blow directly on your head.

    Following a hurricane, damages to a residential structure can range from structural distress, to small areas of mold growth to a total loss of the structure. Storm damage can affect multiple components of a structure including the roof, windows, siding, foundation and interior finishes. Wind or water is often the most common cause of damage to residential properties; however, there are many factors to consider when assessing the various causes of damage. Some of the factors include material use, age, condition and construction methods as well as type, location and extent of the damage. It is essential that a professional with hurricane damage assessment experience evaluate these factors to accurately define the cause.

    One sunny spring morning, on a rural road just outside of Houston, Texas, Molly Jackson, a vibrant 16-year-old girl with a bright future and a new driver's license, was behind the wheel of her father's brand new Chevrolet C2500 crew cab pickup truck. At the same time, just seven seconds before she would draw her last breath, Rhonda Simmons, a 46-year old divorced mother of two teenagers, was approaching from the opposite direction in her sleek and sporty Pontiac Trans Am.

    Editor's note: A trend to require more fire safety equipment in residences and nursing homes will reduce deaths and injuries, both among firefighters and the general public, says E. Metts Hardy, vice president/Fire Investigations for EFI Global (www.efiglobal.com), a Kingwood, Texas-based provider of engineering, fire investigation, environmental, accident reconstruction, and laboratory testing services.

    Nationwide, water-loss claims continue to climb. In California alone, such claims have risen dramatically, with the percentage of homeowner claims growing from 24 percent in 1997 to 32 percent in 2001, costing insurers $1.7 billion. In a single year in California, between 2000 and 2001, claims rose $47 million. For some insurers, this meant that 40 percent of claim payments were for water losses.

    8/7/2013 · Insurance
    Water damage is costly to both homeowners and insurance companies. It is estimated that the cost of household water damage in California, alone, exceeded $500 million for 2002. While the number of water-related claims varies year to year, the average amount paid for such claims increased steadily from $2,577 in 1988 to $3,646 in 2002.

    Despite their history of successful use as fuel system disinfectants and fuel preservatives, antimicrobial pesticide use faces increasing restrictions due to both regulatory control and public concerns. A variety of non-chemical treatments have been used with varying degrees of success to disinfect non-fuel fluids and to at least partially inhibit biofilm development on infrastructure surfaces. Promoters of one technology have claimed successful fuel disinfection and fuel-tank fouling prevention. This paper will review a range of non-chemical treatment technologies and will present the results of preliminary evaluations of several technologies that were tested on Jet A fuels that had been challenged with either Pseudomonas aeruginosa or Hormoconis resinae. Data are presented on treatment impact on adenosine triphosphate (ATP) concentration, culturability and live/dead direct counts in Jet A-1 and on glass microcosm surfaces.

    Smaller retailers depend on the expertise and reputations of their suppliers. Traditionally, refiners' attitudes about fuel were that if it met specifications at the time of sales, but failed later, the problem belonged to the owner at that time. As we begin to see impact of the Clean Air Act-driven fuel reformulations, increased consumer awareness and increased susceptibility to contamination, all market participants are going to have to cooperate to ensure that the customer with the engines gets consistently good fuel.

    2/20/2014 · Metallurgy
    Adenosine triphosphate (ATP) assays have been used to quantify bioburdens (biomass) in low-organic-compoundcontent fluids (freshwater, seawater, cooling tower water, and similar fluids) since the early 1950s. The original methodology was labor intensive and required considerable laboratory skill. Over the past half-century, the protocol has been simplified substantially, but until recently, chemical interferences made it impractical to use the ATP test in metalworking fluids (MWF).

    1/17/2014 · Microbiology
    Quantification of adenosine triphosphate (ATP) in fuels and fuel-associated waters was first presented at the Technische Akademie Esslingen 6th International Fuels Colloquium in 2007. At the time, two issues limited the overall usefulness of ATP as a test parameter: inability to differentiate between bacteria and fungi and inability to detect dormant microbes.

    12/11/2013 · Microbiology
    Three alternative, non-conventional test methods are evaluated for their ability to detect and quantify bioburdens in fuel and bottom-water samples. Two of the parameters, catalase activity and adenosine triphosphate (ATP) concentration have been used previously. This is the first report of the use of fluorescence polarization (FP) technology for fuel and fuel-associated water testing.

    In August, 2012 a member of the LinkedIn Metalworking Fluids Group asked for a recommendation for the best biocide/fungicide package to be used to protect a semisynthetic metalworking fluid from biodeterioration. His posting has generated nearly 50 responses. Some of the suggestions were clearly based on limited experience; experience with few MWF, a limited number of MWF systems or both. I posted a number of comments to the string and have compiled them in this article.

    Industrial lubricants are increasingly providing a rich environment for microbial growth and proliferation. Most of the knowledge of lubricant biodeterioration has been extrapolated from field and laboratory experience with metalworking fluids. Compositionally more complex than most lubricants, metalworking fluids are either solutions or emulsions of 5 to 10% coolant concentrate in water.

    As industry seeks to improve the economy of plant operation, responsible managers are paying more attention to factors that affect efficient and reliable operation of their facilities. One area of attention that can payoff handsomely is the control of microbiological activity in coolant systems. Many engineers and plant operations personnel are just beginning to appreciate the effects on their machining operations caused by their plant "biosphere," which contains bacteria, fungus, mold and other contaminants.

    8/14/2013 · Microbiology
    Mounting concerns over operational and waste management costs, as well as the quality and safety of the work environment have provided increased impetus for both formulators and end-users to strive to improve coolant life. There are a number of alterative approaches to achieving this objective. In this paper, the concepts of bioresistance and biostatic are defined and compared.

    Microbes in Fuel Retailing was the last in my series of NPN articles. In it, I presented a more global perspective on the key issues that I had addressed in earlier articles. Since 1999 there have been some watershed changes in the industry since it was written. The most important ones all involve dramatic changes in fuel product composition.

    Although the documentation of fuel biodeterioration dates back to the late 19th century, general recognition of the value of microbial contamination control evolved slowly until the 1980's. Since the early 1980's a number of factors have converged to stimulate greater interest in fuel and fuel system biodeterioration.

    Metalworking fluids provide an excellent environment for the growth and proliferation of a variety of bacteria and fungi. Historically, the incidence of infectious disease outbreaks at metalworking facilities has been rare. Consequently the primary focus of microbial contamination control efforts has been to prevent fluid biodeterioration.
