Knowing how cranes should be used, and how they should not be used, is critical to crane safety. Overload, side pull, limit switches, secondary braking devices, using the reverse direction for speed control, and daily inspections are surrounded by myth and mystery in the workplace.
This is the first blog in a series on integrating new technologies into the process of forensic investigations. Documenting the scene of an incident accurately, efficiently, and safely is a key step in every investigation. Busy roadways and unstable structures present hazards to the investigator during the investigation process. The use of remote sensors can reduce these risks and provide data that otherwise could not safely be obtained.
Many in the recreational boating public are not aware of a serious type of accident that is neither rare nor without serious consequences. In these incidents the large outboard engine on a fast-moving boat strikes an underwater or floating object, breaks off the boat and flips into the passenger area while still running. The potential for disaster is obvious.
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.
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.
It might seem obvious that a bus driver would know how to properly turn a vehicle with a long wheelbase. Yet it is surprising how many are not taught to. More interesting, bus drivers often do not have the time to.
Given the mass of a bus or motorcoach, the carnage a moving bus or coach can inflict on a pedestrian is not surprising. Yet readers may be surprised by the carnage such a vehicle can cause when it is not moving - or just beginning to move or come to a stop.
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.
For each route in each direction, transit stops are almost always located on one side of an intersection, not both. Stops just before the intersection are referred to as 'near-side' stops. Those just after the intersection are referred to as 'far-side' stops.
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.
