On December 3, 1984, at a pesticide ingredient manufacturing facility owned by Union Carbide, a leak occurred in the Methyl Isocyanate (MIC) plant. Due to the toxic nature of the gases released and the plant's proximity to local residences, the death toll was in the thousands; both plant workers and nearby residents. The first recorded public meeting in response to this incident was on December 9th, in Institute, WV, the site of Union Carbide's only US MIC production unit. Full disclosure: my father was a research & development chemist for Union Carbide and Institute is about 10 miles down the Kanawha River from my hometown of Charleston, WV.

Welcome to the second part in our multipart blog series examining a young boy's fall and injury at a public playground. If you missed the first part in this series, click www.warrenforensics.com/2017/10/11/children-will-fall-at-playgrounds-what-shall-we-do-to-protect-them-a-multipart-blog-series-part-i/ to read it. In this post, we will highlight some resources that designers of public playgrounds can use to help ensure their designs are reasonably safe.

Many people just take for granted that something is just going to work, and in many cases assume that it will work forever. One such device that does not get enough attention is the Ground Fault Circuit Interrupter (GFCI). Simply put, a GFCI is a protective device that compares the current flowing on the hot and neutral wires of the circuit and will "trip" to disconnect power to the circuit if a small imbalance of current is detected. The imbalance of current is an indication of a dangerous alternate path for the current to flow from a damaged line cord or a fault inside an appliance and constitutes a shock hazard to a person.

In 2011, a 5-year old boy was severely injured at a public playground when he fell through a second floor opening around a fireman's pole in a playhouse. He fell more than seven feet and struck a bare concrete floor. We are thankful that he eventually recovered from his injuries. The person who designed and built the playground was accused of negligence. A lawsuit ensued, and eventually settled in favor of the boy.

Event Data Recorders (EDRs) were first introduced by General Motors (GM) in 1974. That data was only available to GM; however, since 1994 more and more vehicle EDR’s have recorded data that can be gathered. The data captured can be imaged and is being used by vehicle manufacturers, law enforcement officers, and collision reconstructionists to better understand what is happening in a collision. In accident investigation, EDRs have the potential to provide independent measurements of crash data that would elsewise be estimated by reconstruction methodology.

6/27/2018 · Corrosion
When thinking about the safe operation of boilers (and don't we all?), several systems can readily be named; flame control, fuel/air ratio; steam pressure control, levels in the vessel, etc. What about the water? It seems so passive, as long as there is enough for level control, what's the big deal? Well, it turns out, that as the steam produced by a boiler is used in the process, the condensate from that steam is returned to the boiler as feedwater. However, since 100% of the condensate is not returned, whatever solids had been in that water before it evaporated to form steam are left in the remaining water. Fresh feedwater is added to maintain levels, but even fresh water contains some dissolved solids. So over time, the water in the boiler system gets saturated with all sorts of dissolved minerals.

    The public looks to safety professionals for guidance as experts in risk avoidance and hazard mitigation. This is reasonable as they are ostensibly trained in that area and, thus, in a better position to evaluate the risks inherent in different activities and to assess what can and should be done to alleviate or reduce those risks to an acceptable level. As such, it behooves safety professionals to be aware of not only safety-related heuristics that are presented to the public, but also the research that underlies that guidance to assess the appropriateness of the various safety rules that are promulgated to address potential hazards. In the real world, however, ostensible safety experts often simply accept these rules as representing appropriate, normal or typical behavior based on longevity, common sense or the simple frequency with which they are expressed.

    Rail residual stress distributions can be complex and variable in nature, as different manufacturing techniques produce varying stress magnitudes and distributions. To evaluate the effect of residual stresses on rail integrity, an analysis technique was sought that could quantify the effect of these stresses on web crack propagation.

    The computer program LS-DYNA3D was used to simulate the behavior of a specific, though representative, heavy truck cab-over tractor-trailer vehicle during a full 180° rollover event. These simulations provide a key component in the development of a physical testing procedure for evaluating structural integrity and occupant crash protection system designs in heavy trucks.

  • The largest storage rack/ retrieval system, larger than two football fields and eighty feet wide was constructed to store 108 million pounds of paper products. On July, 2002, after two months of use, the facility collapsed and sparked a fire that destroyed the entire structure and 45 million pounds of paper. Nearly 50 fire departments responded to the inferno, which burned for three weeks. The owner of the facility sued a number of companies that included the contractor that designed and built the structure, a subcontractor, and the company that supplied the 110 foot steel columns.

    Many automobile accidents are complex cases with multiple events during a single accident. The aim of forensic investigations of such (and all other) accidents is to reconstruct the sequence and the severity of events during the accident and then to establish cause and- effect relationships between the injuries (or damages) and the probable factors - vehicle design (e.g. brakes, structure, airbags); vehicle operator (e.g. distracted driver, alcohol impairment, reduced vision); and operating conditions (e.g. fog, failed traffic sign, excessive speed, icy road).

    Hybrid cars have been on US roads for many years, starting with Honda InSight (1999) and Toyota Prius(2000) in mass production.

    In crashes between two automobiles, it is generally assumed that the lighter vehicle will suffer more damage and that its occupants will suffer higher levels of injury.

    This article contains a few of the findings from our recent study of automobile safety in frontal crashes. Parts of the data analyses are presented but details such as the relationship of a particular design feature to the measured injury indicators are highly dependent on specific cases and are available only for individual discussions.

    The New Car Assessment Program (NCAP) conducted by the National Highway Traffic Safety Administration (part of the U.S Department of Transportation) underwent major changes recently. For automobiles designated as model years 2011 and later, the changes involve both what is measured and what is published.

    Over the years, there have been several product liability litigations regarding pedestrians being injured and the front structure designs of the vehicles being alleged as the significant factor.

    The structural behavior of automobile seats and seatbacks is one of the factors often examined in investigating injuries to a vehicle's occupant(s) in crashes.

    Airbags in modern automobiles have been around for many years and their record in improving occupant safety in crashes is generally well accepted. However, many questions still arise regarding their deployment and performance in crashes.
