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.

    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.

    4/11/2016 · OSHA
    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.

    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.

    10/10/2013 · Ergonomics
    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.

    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!

  • The demise of the hydraulic elevator was forecast with the introduction of the MRL traction elevator about 20 years ago; In spite of this new design conveyance, the hydraulic elevator is again beginning to thrive in the US market. The threat of replacement by the MRL traction elevator is now waning. Hydraulic elevators are still viewed by many within the industry as the best selection for many buildings, in most applications for travel of 50 feet and less, the hydraulic elevator will perform as well as a traction elevator. However, speed and travel is a limiting factor.
