Physics Of The Accident Investigation

The main area of there expertise is to analyse any evidence and determine which, if any, type of accelerant was used. It is similar to the examination of crime scenes as both must be preserved and evidence collected and analysed, but when examining a fire scene numerous additional difficulties and dangers are presented. The investigation normally includes surveying any damage to scene to establish the origin of the fire and establishing the cause.

A. The concept of Normal Accidents is as simple and as complex as the systems it describes. Bell relates to his readers a theory first presented by the sociologist Charles Perrow. The theory of Normal Accidents propose that today’s technologies have become both too complex and too intertwined for accidents to be avoided. As Bell points out, some systems, such as a nuclear power plant, are more complex than others, like a university. The complexity of the system depends upon how “coupled” each individual part is to one another, or in other words, how dependent or independent a component of a system is.

It seems each year that the automobile accidents increase, and there are a high number of death and injuries that follow. Records show that nearly 1.3 million people die in road crashes and 20-50 million are injured. More than half of all traffic death occur among young adults 15-44 years of age( ). Accidents can happen at any time and can be caused by many reasons such as rain, speeding, drug, or alcohol. An automobile accident is what brought the 16-year-old boy to the emergency to be care for by the medical staff there. The patient was seen by the ER staff for several hours, and he was admitted later in the inpatient unit for observation. The next morning when staff tried waking the patient he was died.

Background and Audience Relevance: According to National Highway Traffic Safety Administration, in 2015, about thirty-five hundred people were killed, and four hundred thousand were injured in car crashes.

There are many causes of crashes and fatalities on the road. One cause of death on

For this investigation there were multiple forensic disciplines involved on this case. One of the forensic disciplines that were involved were toxicology. The toxicology team worked to determine if Jessica William had any illegal substances in her body. They also worked to find if there was any impairment involved, which could have been the cause. In her case Jessica blood was found to contain “5.5 nanograms of THC, along with trace amounts of ecstasy” (Cervone, 2013). In this case in the state of Nevada if a person has more than 2 nanograms of THC in their body than they are considered impaired. Another forensic discipline that was involved would have been engineering sciences, which would try to figure out how the accident occurs when mechanics are involved such as cars and roads. Engineering sciences were able to help officers determine what the speed of the vehicle was going at when the incident occurred. With their help they were able to determine the speed of the vehicle and that it was going at a speed of 75 mph on I-15. Forensic pathology was also necessary to determine the death of the victims and identify them for the families as well as identify their wounds.

On 07/17/2016 at approximately 0618 hours, I was notified by Detective M. Carter #181968 of a traffic fatality involving two (2) Toyota Camrys on Broadway Avenue, west of Pine Lawn Avenue. Upon arrival, I observed the involved vehicles at final rest on the outside edges of Broadway Avenue. I observed heavy damage to the front of both vehicles. I made contact with Deputy R. Lariz #4826 and was informed the driver of the red Toyota Camry was transported by Hillsborough County Fire Rescue to Tampa General prior to my arrival. I assumed the responsibilities as the lead detective and Detective M. Carter took the responsibilities as the scene detective. Deputy J. Winters #246608 was assigned the DHSMV traffic crash report

First of all, a causal argument focuses on causes and effects. In this article, authors have discussed how accidents happen while

On 08-08-2016 at 0525 hours, I was notified by Detective M. Carter # 181968, of a traffic crash fatality that occurred at the intersection of Memorial Highway and Kelly Road. at 0451 hours. I responded to the crash scene and upon arrival at approximately 0703 hours, I was assigned to forensically map the scene. I also interviewed two witnesses to the crash, (name & name) (See interviews)

In the experiment, they realized that the persons’ driving style also amounts to over 90 percent of these events. The consenting subjects had to complete a brief questionnaire about their personal characteristics and the features of their collision. Researchers then collected the phone records of each person's cellphone number and verified each invoice by checking the subject's full name, mailing address, and calls made to his or her home phone. For each record, they analyzed all of the telephone activity on both the day of collision and the preceding seven days, with particular attention to the time, duration, and direction (incoming or outgoing) of each call and a special note was made if there was any contact with ambulance personnel, police, or other emergency services. The information that got collected showed that cellphones impaired the drivers’ ability to control the vehicle properly, which then resulted in the vehicle crashing. (Donald A. Redelmeier, M.D., and Robert J. Tibshirani, Ph.D., New England Journal of Medicine)

In this Car Crash Project, we had to make sure we used Newton’s 3 laws. Let me explain you how I used the 3 laws in my project. For my project, I had three main important parts in my car. One of them was the crumple zone because the car is in motion until it hits the yellow which is the outside force. In Newton’s First Law he states that every object stays in motion unless acted upon an outside force. Here the object in motion is the car, and the outside force is the yellow stump. Another main component was the seat belt. The seat belt fell in Newton’s Second Law. In that law, it explains how force equals mass x acceleration. So, When the egg is wearing the seatbelt it will stop the egg from accelerating or being in motion. If it was accelerating

In summary, it cannot be said that exact cause of most severe traffic accidents are known with certainty but it is believed that speeding and drinking, jointly or separately, play some role in the events that lead up to those accidents. Also to blame, in many instances, are the design of the highway, the condition of the weather, the maintenance of the vehicle, the time of the day (many severe accidents occur at dusk, with poor lighting and tired drivers), and the presence of radar detectors. A study by the Ohio State Police found that radar detectors were present in at least one of the vehicles involved in 69% of all severe traffic accidents on the highways of that state in 2005. Studies in other states have confirmed that finding, with some estimates of the relationship running as high as 75%.

It must be noted that cars are dangerous vehicles which can cause fatal damage. Individuals responsible for a vehicle are expected to be more alert than pedestrians walking down the street or crossing the road, this is known as “destructive disparity”. This

Normal accident theory and Swiss cheese model are influential models in studying system accident causation. This paper is going to help us to gain understanding of both models and to critically compare them. The first part of the study is an introduction of the both models. In the second part, Three Mile Island nuclear accident will be taken as an example to see how the models analyse causations of an accident. In this part, the fact of the accident will be presented first, then normal accident theory and Swiss cheese model will be invited to identify the causes of the accident respectively. The evaluation and comparison of the two models will be discussed in the final part. Both models conclude that accidents are
