    Following a fire event, a variety of people spend considerable time in the post-fire environment. In addition to first responders, fire and law enforcement, the individuals performing investigations in the property can include insurance claims adjusters, origin and cause fire investigators, inventory assessors, and damage assessors. The fire service, EMS and law enforcement may typically be assumed to be wearing appropriate personal protective equipment (PPE), but exposure to post fire hazards should be considered for those entering the property and performing work well after the fire event.

    Polychlorinated biphenyls (PCBs) are present is a variety of building materials and may present a significant impact to construction projects. The presence of PCBs in caulking, sealants, paints, adhesives and other building materials dates from the 1930s to the banning of PCBs in domestically manufactured products in 1979. In that time period, however, PCBs were added to hundreds of building products due to their chemical stability, nonflammability, insulating properties and high flash point.

    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.

    Resistance to conventional pesticides has been growing rapidly among all pests. Furthermore, there is increased public concern about the safety of conventional pesticides, and increased governmental restrictions have resulted in the need to identify new compounds that are safe and effective in controlling pests that are of concern to agriculture as well as to public and animal health. Biopesticides may aid in the control of such pests with fewer deleterious effects to the environment, people and animals.

    The question is often posed, "How much will it cost to clean up contamination at a drycleaner?" Invariably the answer is, it depends. Factors that come into play include, but are not limited to, the concentration of VOCs present in the subsurface, whether or not the groundwater is impacted, the depth to groundwater, how far the contamination has spread, whether the cleanup will be focused on residential or commercial land use, and the type of geology and stratigraphy underlying the site. This article focuses on how clayey soils affect cleanup considerations.

    6/21/2016 · Environment
    The fundamental, hard-fast goals of a subsurface remediation project are to stop any current human or ecological exposure; and to avoid any potential future human or ecological exposure. Here are some of the basic concepts and economic considerations used to determine effective site cleanup strategies to attain regulatory closure at contaminated sites.

    Selecting an environmental consultant can be a daunting task and for small business owners that do not have day-to-day exposure with soil and groundwater contamination it's very difficult to know the difference between consultants. This article is meant to shed light on the differences between environmental consultants and to present the different methods for selecting an environmental consultant. It's my goal to show people that selecting the right consultant for your situation is a very important decision and should not be taken lightly. If a business person doesn't know that there are differences between environmental consultants, countless hours and dollars may be wasted, projects could drag on and site closure could be a distant glimmer.

    Vapor Intrusion, or VI, occurs when contamination beneath the ground emits toxic vapors that can travel through the soil and enter the interior spaces of houses and buildings. The types of contamination most commonly associated with VI concerns are industrial solvents like chlorinated volatile organic compounds (CVOCs), and petroleum products like gasoline. The Environmental Protection Agency just released final guidance on vapor intrusion issues, which regulates how inhalation exposures from VI are assessed and controlled.
