    ln our current climate of economic prosperity and rising real estate values, the prevalence and usefulness of construction litigation may be on the wane. Much of the litigation and expert opinion in recent years has resulted in unrealistic repair schemes for the sole purpose of producing a settlement among parties to the litigation. When a plaintiff expert recommends a "remove and replace in its entirety"1 scenario (for example, arguing that all exterior stucco must be demolished and reinstalled due to a lack of expansion joints), the defense expert frequently advocates a more modest "fix what's broken" scheme to provide a minimum repair at the lowest cost. This process consumes considerable time and resources, and creates a difficult environment in which to craft a settlement. More often than not, neither party is pleased with the outcome; unreasonable plaintiff positions often result in settlement amounts ranging between 15 to 25 percent of the claim amount.

    Welcome to the third and final post in our multipart series of blog posts about a young boy's fall and serious injury at a public playground. In our first post we gave a brief overview of the incident and our investigation. In the second post we discussed some of the safety standards applicable to public playgrounds. In this post, we will examine some of the impact-absorbing playground surfaces available to protect children at playgrounds from injury. If you would like to read the first two posts, they are available here and here.

    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.

    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.

    Airbags are credited with reducing numerous injuries and saving many lives during vehicle accidents. However, there have been incidents where they do not function as intended, and have even caused injuries such as explosive powder burns, detached eye retinas, child suffocation and impact deaths.

    Animations are useful visual tools that can help jurors understand how an incident could, or could not, have occurred. Simply describing an event in court, or showing still pictures, may be insufficient to explain a complex sequence of events.

    Biomechanics is the application of mechanics to the interaction of biological systems with their external environment. When investigating an accident, biomechanical analysis can be used to reconstruct a victim’s motion and relate it to his injuries.

    When an understanding of complex motions associated with various accidents is required, computer simulation is an invaluable tool, which allows the modeling and visualization of rollovers and collisions. In addition to vehicle accidents, computer simulation can also be used to create many other systems of masses and contacting surfaces, such as a toppling light pole after it has been struck.

    Construction sites and equipment present many hazards if proper care is not taken. The space in and around a construction site is often filled with potentially dangerous, high-powered equipment capable of delivering high forces.

    Doors and gates, whether automated or manual, can pose a serious hazard to users if not designed, manufactured, installed and maintained properly. The different types include automatic doors, overhead garage doors, elevator doors, sliding doors, swinging doors, and automatic gates.

    Electric fires are becoming more common as appliances and electric feeds are used more and more in our daily lives. Like other fires, the root cause of an electric fire is the introduction of heat, oxygen, and fuel.

    Electric power and electronic appliances are so integrated with modern life that there is a high degree of likelihood that everyone will receive one or more electric shocks in a lifetime. In many cases, only trivial power levels are involved.

    Second only to automobile accidents, falls are the leading cause of injury and deaths. Of these, accidents due to slipping or tripping form a large proportion. Slips and trips occur on floors, streets, walkways, stairs, etc.

    Forklifts, industrial trucks, skid steer loaders, bobcats and other similar material-handling machines are often difficult to maneuver and susceptible to a wide range of accidents. Their nature exposes operators and nearby co-workers to falling loads, crushing hazards and lading dock falls.

    There are roughly 9,000 golf cart related accidents requiring emergency room treatment in the United States each year. The majority of these accidents are related to either braking, cart rollover or passenger ejection. These problems are common to golf carts due to their open design, lack of seatbelts, poor braking capabilities and the uneven terrains they are driven on.

    The primary function of all guarding is to prevent an operator or bystander from being injured by a potentially dangerous portion of a machine. Often the hazard involves moving parts with the potential to cut, crush or draw-in body parts, although barrier guards may also be necessary when electrical, thermal or chemical dangers are present.

    Human Factors and Ergonomics (HFE) is a branch of science, which is concerned with man’s interaction with his universe. Thus, it is not simply the study of pure science (e.g. sound or light), but rather man’s understanding and reactions (e.g. to hear and see).

    There are over 100,000 ladder accidents annually in the U.S. requiring hospital emergency room treatment. Although many of these result from user misuse, such as an improper extension ladder lean angle against a wall causing it to slip outward, use of a damaged ladder, or failing to lock a step ladder’s spreaders, many ladders fail due to design or manufacturing defects.

    Motorcycles, like passenger cars, are capable of high speeds and must share the road with other vehicles. However, unlike passenger cars, motorcycles are capable of rapid accelerations, offer little protection to the operator during a collision and require special skills to maneuver effectively.

    In many vehicle accident investigations, it is necessary to know not only the speeds and motions of the vehicles involved, but the causes of injuries suffered by their occupants as well. Such investigations seek to answer questions regarding occupant ejection, effects of seatbelt use, airbag deployment and body-interior impacts.

    Parking lots are the scene of many pedestrian accidents because of the close proximity of people and cars and the confusing traffic patterns that sometimes exist. In addition to pedestrian-vehicle collisions, many trip and fall accidents occur in parking lots as well.

    Though swimming pool accidents are sometimes the result of reckless participant behavior, they can also be caused by inadequate supervision, warnings, structures, or defective pool design. Structures commonly found in or near swimming pools include slides, ladders, diving surfaces and fencing.

    Approximately 125,000 serious injuries occur in the US each year related to the use of portable and fixed power saws. Lacerations and similar injuries, such as abrasions and avulsions, account for over 90% of these, which generally occur to males and result in losses in the tens of millions of dollars annually.

    An end user of a product expects that a given product will not only function as intended, but will be safe from non-obvious hazards. Based upon decades of experience with mishaps during use of common and specialized equipment, thousands of standards have been developed for many consumer products and industrial equipment. Numerous organizations exist, e.g., ANSI, ASTM, SAE, and ASME, that regularly review and update these standards.

    Places of business, residences, parking and recreational areas contain potential accident sources such as slippery floors and stairs, product displays, automatic doors, ledges, railings, elevators, escalators and other hazardous items. To prevent such items from causing injury to the public, premises owners and their agents have a responsibility to recognize unsafe conditions and exercise reasonable care to maintain or make conditions safe, or warn the public of the risks involved.

    Supermarkets, pharmacies, home improvement, and department stores expose their customers to many potential accident sources such as floors and aisles, which can become unsafe, and display merchandize that can topple or cause tripping. To prevent such accidents from occurring, these establishments should maintain routine scheduled inspections to insure that unsafe conditions are detected and corrected before accidents occur.

    In many vehicle rollover investigations, it is necessary to know not only the speeds and motions of the vehicles involved, but the causes of injuries suffered by their occupants as well. Such investigations seek to answer questions regarding occupant ejection, effects of seatbelt use, roof crush and body-interior impacts.

    Motor vehicle seatbelt use provides highly effective protection in frontal collisions for impact angles up to 30 degrees off-center (i.e. between 11 and 1 o’clock). All states have laws requiring their use for front seat passengers, as they have been shown to reduce moderate to severe injuries by 50%. They are less effective when your car is hit in the rear or side and sometimes their locking devices malfunction or the anchorage gives way.

    Recreation, sports, and gym equipment are subjected to large dynamic forces and must be designed to support these loads and protect users from unintentional hazards. Adequate instructions and warnings may be required if their assembly and proper use are not obvious.

    Codes and standards specify criteria necessary to ensure that a product, material or process will consistently and safely perform its intended function. Although standards provide minimum design requirements, conforming to a standard is not always sufficient in preventing an accident.

    Structural failure can often produce catastrophic results. In many cases, the damage seen after the accident is not indicative of the cause of the initial failure. Fortunately, based on physical evidence, an investigator can frequently determine how and why a structure failed.

    Heavy trucks, whether tractor-trailers, construction vehicles or garbage haulers, are involved in many serious traffic accidents due to their large weight, high centers of gravity, decreased visibility, poor handling and reduced braking efficiency. In addition, articulated tractor-trailers are subject to additional problems such as jack-knife and trailer sway instabilities.

    Motor vehicle accidents are the most common type of incidents producing injury in the US. The main issues in litigating automotive accidents involve vehicle speeds, seatbelt usage, airbag deployment, vehicle component failure (e.g. steering, braking), roadway design, occupant biomechanics, rollover, visibility, etc.

    A person’s interaction with his environment comes largely from visual cues. Without this information, a pedestrian can trip over an unseen object or a driver might not detect a dangerous situation. In order to avoid these hazards, a person requires adequate lighting and should be provided with appropriate illumination for a given task.

    A warning must inform individuals of a danger, which would not be obvious to them. It must tell them how to avoid the danger, and be easily understood. It should also provide them with the consequences of not heading the warning.

    A car is stopped for a light when it is unexpectedly rear-ended causing little or no damage to either vehicle. Nevertheless, the passengers of the struck vehicle complain of neck, shoulder and back pain. Insurance claim representatives, attorneys, medical, engineering and biomedical experts are then brought in and various conflicting allegations, testimony and opinions are expressed.

    Pedestrian and bicycle accidents in the United States result in approximately 80,000 and 50,000 injuries each year, respectively. Though pedestrians and bicycles move differently, they share important characteristics as both have little protection during a roadway collision with a motor vehicle.

    A standard can be defined as a document issued by a recognized agency, and dealing with design and/or safety requirements relating to a specific product or type of activity. Such agencies include the U.S. Occupational Safety and Health Administration (051-IA) and the American National Standards Institute (ANSI). OSHA standards are generally legally binding for an employer, while ANSI standards are generally of an advisory nature. The term "industry standard," however, is ordinarily taken to have a broader meaning, including formal standards as just defined, and also including designs and procedures not required in formal standards, though prevailing in a specific industry, and which represent generally accepted custom and practice.

    7/14/2009 · Forensic Analysis
    Persons with no training in engineering are generally unaware of the nature of engineering analysis, and so tend to assume that testing, as a means of determining the causation of accidents, is a dominant tool of the engineer. In the following examples, we shall undertake to explain the nature of engineering analysis, and to show that it is more basic than testing because testing without analysis is meaningless. Further, while analysis is always necessary in accident reconstruction, testing is only sometimes necessary.

    There are approximately 180,000 lawnmower accidents per year. In this introductory presentation, we undertake to describe the various ways in which these accidents occur.

    7/14/2009 · Forensic Analysis
    Second to automobile accidents, accidents due to falls are the leading cause of injury and death. Of these, accidents due to slipping (not tripping) form a large proportion. Slipping may occur on floors, walkways, and stairs or steps. For Introductory purposes, however, the present discussion will be limited to slipping on flat surfaces such as a floor or sidewalk.

    7/14/2009 · Human Factors
    When a person becomes aware of a dangerous situation, a time-interval must elapse before he can take defensive action against it. This time interval, commonly called the reaction time, has been found to be about 0.7 second for all normal persons, regardless of their background and training. This suggests that the reaction time depends on some basic aspect of the human physiology-involving the brain, nervous system, and muscles-which does not vary much from person to person.

    A car is stopped for a light when it is unexpectedly rear-ended by a vehicle from behind. It is not a hard impact and there is little or no damage to either vehicle, because the energy absorbing bumpers have protected them. Nevertheless, the passengers of the struck vehicle complain of neck, shoulder and back pain. The next day they allegedly experience even greater pain and visit a medical person who claims that they have been injured. Insurance claim representatives, attorneys, medical, engineering and biomedical experts are then brought in and various conflicting allegations, testimony and opinions are expressed. Do we have a legitimate injury claim on our hands or a situation of fraud?

    7/14/2009 · Forensic Analysis
    Accident reconstructionists are often called on to determine the distance that a car, covers while being braked to a stop. Conversely, the reconstructionist may be given information as to the length of the skidmarks left by a car on the roadway, and may be asked to determine how fast the car must have been going at the beginning of the skid. An expert can accomplish this with considerable accuracy, based on a knowledge of the physical principles that are involved, plus available information relating to the friction of tires on various types of road surfaces.

    7/14/2009 · Forensic Analysis
    According to the Consumer Products Safety Commission (CPSC), there are approximately 10,000 golf car related injuries requiring emergency room treatment in the US each year. One significant mode of injury in golf car accidents is passenger ejection, which can lead to serious injuries, especially of the head. Based on CPSC statistics, roughly 35% of golf car accidents involve a person falling out of the car. In addition to ejection accidents, at least 10% of golf car accidents involve a rollover and statistics indicate that such accidents are roughly twice as likely to lead to injuries requiring a hospital stay as non-rollover accidents.

    7/14/2009 · Forensic Analysis
    According to Consumer Product Safety Commission (CPSC) accident estimates, tens of thousands of stepladder accidents requiring emergency room treatment occurred annually in the United States. Approximately 85-90% of these accidents involve the user falling from the ladder and 8-9% of these injuries are serious enough to require that the victim be admitted to a hospital. In addition to posing a severe health concern, these accidents have significant loss-of-wages and high medical expense implications.

    Hazard recognition plays a vital role in keeping employees safe. Some hazards are easily recognized, for example an employee climbing up a 20-ft ladder while holding tools in both hands is an obvious fall hazard. While some safety hazards are immediately recognizable, others require training to spot and avoid. One such hazard is hydrogen sulfide (H2S). Training is a key method to avoid the "ostrich zone." You do not want to bury your head when facing this hazard.

    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.

    5/16/2018 · Expert Witnessing
    Lawyers and courts turn to expert witnesses to provide triers of fact with explanations of aspects of a case that are not commonly known. It is the subject matter expert's education, experience, and skill in a particular area that will help the triers of fact to reach a well-informed conclusion/decision. Examples of expert witnesses include medical doctors, accountants, engineers, DNA scientists, and more. Lawyers (and the courts) will employ an expert witness to shed more light upon factual issues for the purpose of discerning the truth. In short, expert witnesses educate, clarify, and explain a subject that is not common knowledge for most people.

    10/17/2017 · Expert Witnessing
    The employ of expert witnesses in litigation is typically undertaken to help the decider of fact (judge or jury) decipher an area of specialized knowledge which is key to the case. The expert report serves the primary purpose of "educating" deciders of fact on topics not commonly known to the general public. However, a noncomplying expert report can wreak havoc on a case, increase costs or worse, have the expert's testimony precluded in whole or part from use at trial. This of course is contrary to the purpose of retaining an expert in the first place. Understanding the parameters of compliance (C.R.C.P. 26 (a) (2) (B) (I)) and how sanctions for non-compliance (C.R.C.P. 37 (c) (1)) may be applied is important not only for legal counsel but the expert as well under the 2015 rule updates and the recent Colorado Supreme Court case, Catholic Health Initiatives Colorado v. Earl Swensson Associates, Inc.

    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.

    In 2005 a summary of "General Duty Clause" citations issued for ergonomic hazards was published (Purswell & Purswell, 2005). That summary showed that the primary area of ergonomics citation activity under the "General Duty Clause" (paragraph (5)(a)(1) of the OSHAct of 1970) by OSHA to that point had been concentrated in nursing homes, peaking in 2002 and 2003.

    The purpose of the current study was to update and expand upon an earlier study performed to review and categorize OSHA accident investigation records for pedestrian-backing vehicle accidents according to whether the backing vehicle had a backup alarm and whether the alarm was installed and functioning as intended. The current study includes an analysis of additional records as well as the business type (SIC code) of the employer.
