    During a recent conversation with a friend who had purchased a small construction company he mentioned in passing that one of his employees had injured his ankle on the job but didn't report it to his work comp carrier as it was a minor incident, no days off work, didn't want his rates to go up, why bother. All is good. Right?

    Electricity is a vital source of energy in our daily lives. It powers tools, provides light and heat. Our working lives are much improved and efficiency greatly increased thanks to electricity. But what about those situations where power from the grid is unavailable. Well, portable generators are an excellent tool for such a scenario.

    Safety culture is a term frequently bandied about in today's business world and sounds as trendy as "mission statements" were years ago. (Let's not forget "best in class". First time I heard this at a company meeting I looked around to make sure I hadn't mistakenly wandered into a dog show. Really?)

    Use fall protection; Use trench boxes when excavating; Lock out Tag Out any time repair or maintenance of equipment involving stored energy is performed; Slips, Trips and Falls are one of the most expensive types of injury. For my sixteen years in safety these safety hazards were always in the forefront of safety concerns for businesses and safety professionals. Guess what? Work related road way crashes is the number one serious/fatal injury cause for U.S. workers. OSHA recognizes this. CDC/NIOSH has generated a white paper studying this fact. Who knew? So here is some info on this number one safety hazard in the US work place.

    In the safety world hazard recognition plays a vital role in keeping your people safe from unsafe behaviors and/or conditions. Some hazards are easily recognized, for example an employee climbing up a 20 foot ladder with tools held in both hands. (This is a fall hazard by the way.) Common sense right? The safety guy who taught me safety had a great response to this attitude, "Few people have any sense (read knowledge) in common (read shared alike)". So while some safety hazards are immediately recognizable others require training to spot and avoid. Training is a key method in avoiding the "Ostrich Zone". One such hazard is Hydrogen Sulfide. You don't want to bury your head facing this hazard. (Won't do much good anyway, Hydrogen Sulfide is heavier then air!)

    "If you don't know where you are going, you will probably end up somewhere else.", so said Laurence J. Peter, a professor at the University of Southern California whose works touched the business world. (He is well known for the "Peter Principal".) Peter's above quote essentially points out that action lacking a clear objective will likely lead to unwanted or unintended consequences.

    When personal injury events occur legal negligence actions may arise. Common law negligence is established by plaintiff showing defendant owed plaintiff a legal duty, to conform to a standard of care, defendant breached that duty, plaintiff suffered injury and there is a causal relationship between the breach and injury. FN 1 But what sources of standard of care proofs are available? How does a litigant go about proving standard of care?

    Read Consulting was asked to determine why a welded chair failed and caused injury to the person sitting in it.

    The root cause of the failure of customer returns of heated automobile rear view mirrors was investigated.

    During normal operation, the arm on an automatic wafer test station failed. Root cause failure analysis determined that the drive shaft on the right angle gear motor used to raise and lower the manipulator arm had failed first.

    5/21/2012 · Failure Analysis
    This grinding wheel was part of a product liability and personnel injury case. It was claimed that the subject wheel had unexpectedly failed (i.e. flown apart) and an escaping piece had hit the plaintiff in the face causing serious injuries. According to the user, the grinder with the wheel was purchased approximately one hour before the grinding wheel failure.

    3/29/2012 · Failure Analysis
    A failed plastic lawn chair was examined to determine the cause of failure. This chair failed on the premises of a restaurant In this study the subject chair is examined and compared to several exemplar purchased at the same time.

    5/17/2011 · Failure Analysis
    A plumbing failure analysis was performed to determine why a cold water supply line to a bathroom sink had failed after only one year of service.

    A glass failure expert witness performs a root cause failure analysis on an exploding beer bottle. The object of this root cause failure analysis is to determine the cause of the bottle failure.

    7/7/2009 · Design
    Before expending the effort necessary to reverse engineer a device or object, it must be definite that the object under study is not covered by one or more patents. This avoids a dispute over patent violations. Once it has been established that no patent coverage exists, one can use multiple techniques to reverse engineer a product. These are summarized below:

    The cracked tank was first inspected in the "as received" condition. In this condition it was cracked, but it was still whole. Next, the failed tank was separated by pulling it apart. This was done to expose the fracture surfaces of the main crack. This allowed for a complete failure analysis and for a determination of where the crack initiated.

    Glass fractography is the most effective method for determining why a glass object, such as a bottle, failed. This technique consists of examining the fracture surfaces of the failure for artifacts such as Wallner lines and using them to trace the crack back to its origin. Once the origin has been identified, it can be examined in detail with a microscope to determine the cause of the failure.

    You have a shiny new building with a shiny new crane and everything looks great. For some reason, though, the crane won't clear the building columns, even though the contractor and the crane manufacturer are saying everything is to spec and it's not their problem. Common sense says somebody is wrong and that somebody should have to pay (because it's going to cost a bundle).

    5/10/2016 · Construction
    It is absolutely critical in the evaluation of a legal case involving cranes, to determine what type crane is involved. The word "Crane" is a generic term that covers virtually anything that lifts with a hook, but each crane type is a whole different industry with different industry associations (which compile the industry product specifications), different governing specification and different OSHA requirements. As a matter of fact, some cranes don't even have hooks!

    Tree stand accidents occur frequently during hunting season, causing a variety of injuries from broken bones to paralysis and death. Tree stand accidents involve a variety of causes, including falls from the tree stand, collapse of the tree stand, fires, self inflicted gunshot wounds, and asphyxiation. A study by the Center for Disease Control examined hunting accidents from 1979-1989. 214 of 594 deer hunting related accidents involved tree stands. 52% of these tree stand accidents were due to falls from the stand, 32% were due to collapse of the tree stands.

    This issue of Forensic Clues is the second installment of an examination of ladder accidents. Last month we explored stepladders, this month we will be discussing extension ladders. Ladder accidents are a very common occurrence. Over half a million people annually seek medical attention due to ladder accidents. Over three hundred people are killed yearly in these often preventable accidents. This is a serious problem.

    Ladder accidents occur frequently, often with very serious consequences. Ladders are tools that people use repeatedly, at home and on the job. The CPSC (Consumer Product Safety Commission) states that there are more than 164,000 emergency room-treated injuries annually due to ladders in the United States.

    The nursery rhyme involving Humpty Dumpty is a child's first lesson in safety. What would keep Humpty Dumpty safe as he is sitting on the wall? A warning or a railing?

    6/29/2015 · OSHA
    The Bureau of Labor Statistics estimates that between 1,600 and 2,000 amputations occur annually due to power press operation. Another 18,000 people receive less serious injuries annually. Injury statistics compiled by OSHA for the years 1975 through 1983 confirm these figures. These numbers are alarming and unnecessarily high. Power presses can be used safely when the presses are properly designed to minimize the hazard that the operator is exposed to.

    5/26/2015 · Machinery
    Every year there are thousands of debilitating injuries and deaths on farms. Many of these are related to power take-off's (PTO's). PTO shafts are used to power various farming implements, from mowers, hay balers, augers, and many other types of farming machinery. The PTO shaft was invented in the 1930's. The PTO shaft is essentially a shaft powered by the tractor engine that rotates at high speeds, providing power for a wide array of implements. While this provides a convenient source of power to drive farm implements, serious accidents can occur due to entanglement in PTO's. PTO's must be properly equipped with guards including master shields which covers the stub shaft and universal joint. These shields prevent inadvertent contact with the rotating machinery. Contact with unshielded rotating PTO parts can instantly pull a person into the PTO, causing catastrophic damage.

    Rock and ice climbing have become increasingly popular in recent years. Climbing is now a popular form of exercise and adventure, and a great way to enjoy the outdoors. Unfortunately the greater numbers involved in the sport has led to greater number of accidents. Climbing gyms have brought climbing to areas without outdoor rock resources. These indoor gyms use artificial holds to simulate rock walls. Indoor climbing gyms typically have climbs ranging from twenty feet to fifty feet, or more. Bouldering areas are shorter in height, with adequate padding to protect climbers from falls without the need for ropes.

    While many accidents involving products are the result of a product defect that leads to injury of the product user, accidents can also be the result of a failure caused by lack of maintenance or inspection. This issue of Clues will examine the theory behind failure to maintain accidents, as well as provide examples of common accidents that are due to a lack of maintenance.

    Material science is a broad field that has applications in numerous fields. In product injury cases, material science can help identify defects, determine causes of accidents, determine failure modes, and identify inconsistent manufacturing processes.

    1/21/2015 · Product Liability
    No one likes to see children get hurt, especially when it could be prevented. Poor design, manufacturing defects, material defects, assembly errors, and the lack of a hazard analysis can result in hazardous products that injure people. Many products are put in stores that may have never been looked at by a design engineer and/or a safety specialist.

    Fishing and boating accidents result in thousands of injuries each year. The U.S. Coast Guard reported 3331 injuries and 709 fatalities due to boating accidents on both recreational and commercial vessels. There are many causes for these accidents, including collisions with objects or other vessels, drowning, electrical and mechanical failures, interaction with unguarded machinery, and others. There are various acts and laws that govern accidents at sea. This issue of Forensic Clues will examine some of the preventable accidents caused by defective machinery and equipment that occur at sea, and a brief overview of the laws and regulations affecting product liability litigation related to maritime accidents.

    Paintball is a fun activity for all ages, and can be a safe sport if proper precautions are made. Serious eye injury can occur if a paintball impacts the eyeball, making goggles and facemask a requisite part of paintball. Accidents happen in backyard paintball games most frequently, but also at commercial paintball operations. This Clues will examine the typical preventable paintball accidents, as well as examine product failures that can lead to accidents while playing paintball.

    Accident reconstruction involves attempting to determine the sequence of events of an accident and is a crucial part of product liability cases. Understanding exactly what occurred in an accident gives an engineer the best chance of preventing the accident from occurring again. Often there is limited information to base conclusions on what really happened in an accident. Understanding what goes into accident reconstruction will help attorneys understand what information is crucial to this process. Witness testimony is unreliable at best but must be analyzed and cross referenced with the other available information.

    Lawnmowers cause over 50,000 emergency-room visits every year, based on NEISS data on consumer product injuries. These injuries are distributed evenly between ride-on and walk-behind style mowers. The necessary cutting action of a mower results in an inherent hazard, until technology is developed that can cut grass but not living tissue. While various safety advances over the years have reduced the amount of injuries, the extremely high number of accidents related to mowers that continue to occur show the need for further enhancement of product safety.

    Machine guarding accidents cause many accidents and fatalities every year, despite the availability of modern safety technology. In the years from 1992-1996, one study from the Bureau of Labor Statistics (BLS) reported annual injuries due to workers being caught in machinery of 34,350. In 2012 contact with an object or equipment had the second highest workplace fatality rate at 712 deaths.

    6/10/2014 · OSHA
    OSHA was created through the Occupational Safety and Health Act of 1970. OSHA's mission is to ensure worker safety by creating and enforcing safety and health standards. OSHA does many good things to help maintain a safe workplace, but manufacturers often try to hide behind the shield of OSHA, putting blame on an employer for unsafe machinery or working conditions, when often the machinery was never safe to begin with. Some standards promote safety and some standards protect the manufacturer from product liability law suits. Most industrial standards are voluntary, unless they are specifically referenced in a Code of Federal Regulations / OSHA standard. OSHA standards are Federally mandated and are enforced by the Federal government.

    Stored energy is accumulated energy, which can release suddenly, potentially causing serious injury or death. Stored energy has many forms, including pressurized gases and liquids, stored mechanical energy, stored electrical energy, and gravitational potential energy. Stored energy is particularly dangerous because the hazard still exists when the original source of energy is removed. This issue of Clues will explain the various forms of hazardous stored energy, how these energies can cause damage or injuries, and how to prevent stored energy accidents.

    Table saw accidents occur frequently, often resulting in serious accidents when the operator comes in contact with the saw blade. The difficulties in guarding table saw blades with conventional guarding techniques often leads to ineffective guards that are removed by saw operators due to their lack of function and flexibility.

    9/26/2013 · Failure Analysis
    In 2007, an estimated 15,147 lives were saved from seat belt use. Seat belts save five times more lives than airbags, according to statistics released by NHTSA. Seat belt use has increased over the years, due to cultural trends, and possibly due to the enactment of seat belt use laws. Seat belt systems do not always function as predicted. Seat belt systems can fail during a collision, often resulting in serious injury or death to the vehicle occupant.

    Farming is a dangerous occupation. Tractor rollover accidents have been killing people since the 1920's. In 1990, the National Safety Council estimated 460 people were killed while operating tractors. Tractor rollover caused 239 of these fatalities. Another estimate suggests a more conservative number of annual fatalities - 132, that are the result of tractor rollover accidents. In a four-year period in Pennsylvania alone, 72 people died as a result of tractor rollover accidents.

    Automobile collisions result in damage to property and injuries to people. Compensation is sought through insurance claims, law suits, and product liability claims. Knowing when injuries are more or less severe than is warranted by the damage level involved in the collision is important information. This can help people involved on both sides of litigation or settlements.
