Stirling Bridge had been a thriving power tool business for over 100 years. The company had sold and distributed power tools and equipment all over the U.S., Europe, and third world countries. Recently one of Stirling Bridge’s top selling products, the Braveheart power tool line, came under attack when consumer agencies conducted research and found many consumers who purchased the power tools were experiencing significant harm and personal injury after use. Stirling Bridge (STIRLING BRIDGE) had identified potential safety concerns with their power tools and hired an independent research company to investigate why consumers were being injured using their power tools, well before the company came under the attack of public agencies.

The Safety Board’s lengthy investigation revealed the possibilities of short circuiting wire systems as a source of ignition within the fuel tank, which would provide the minimum ignition energy required according to the parameters established by the American Petroleum Institute (API) as well as the analysis of the conditions within the CWT at the time of the incident. The he...
The document I chose to write about is the United States Constitution. When the thirteen British colonies in North America declared their independence in 1776, they laid down that “governments are instituted among Men, deriving their just powers from the consent of the governed.” The “colonies” had to establish a government, which would be the framework for the United States. The purpose of a written constitution is to define and therefore more specifically limit government powers. After the Articles of Confederation failed to work in the 13 colonies, the U.S. Constitution was created in 1787.
The United States Constitution is founded on the principles of natural law. This law governs and transcends any political activity is a state theory based on the idea of social contract, the people are the source and basis of the authority of the rulers. The Constitution defines the principles of a federation that recognizes both levels of government based on the separation and balance of powers and the division of responsibilities between the federal state (foreign policy, defense, foreign trade and between States, etc.) and the Federated States (justice, health, protection of individual rights, education, etc.). The constitution is therefore much more than a piece of legislation because it relates to the greatest debates of American
“While the authors of the United States Constitution are frequently portrayed as noble and idealistic statesmen who drafted a document based upon their conception of good government, reality is that the constitution reflects the politics of the drafting and ratification process. Unfortunately, the result is a document that is designed to produce an ineffective government, rather than a government that can respond to issues in a timely fashion.” In support of this conclusion, the issues of slavery, The 1906 San Francisco Earthquake, and the civil rights struggle keenly demonstrate the ways in which our constitution hinders the expediency and effectiveness of America’s government. The constitution’s provisions towards voting eligibility and separation of powers proved to be the most significant obstacle in the path to emancipation for slaves in the 19th century. The way in which federalism is laid out within the constitution played a monumental role in the communication barriers that arose during the 1906 earthquake, delaying assistance to thousands of Californians. Lastly, a number of constitutional provisions, including voting rights and the 3/5 compromise, impeded the struggle for civil rights in the 20th century, again exemplifying that lack of efficiency that the constitution produces.
Since early 2003 the Electrical Inspectorate has been working to raise public awareness of Residual Current Devices (RCDs), with the aim of eventually enforcing the use of these devices as recommended by the standard adopted by the St. Lucia Bureau of Standards for wiring of buildings SLNS/BS 7671: 2001- Requirements for Electrical Installations ¡V IEE Wiring Regulations ¡V Sixteenth Edition. These Regulations though only recently adopted by the Bureau of Standards is the Regulations referred to by the St. Lucia Electricity regulations of 1973 as the standard of wiring of buildings. For a very long time the cost of these devices had proven prohibitive for the enforcement of the requirement. However, it is now believed that safety concerns as it relates to electrical hazards such as fire and electrocution far outweigh the cost of these devices
The Constitution created a government of limited and expressed powers. The Constitution is the supreme law of the land. It was written to make good government and laws, and to provide freedom to all, thus creating a healthy nations. The Articles of the Constitution express the roles and duties each part of the government has. It also separates power between the federal and state governments.The founding fathers knew that as time changes, so do the needs of society and the government needs to address this change. Article 5 states, “The Constitution can be changed. New amendments can be added to the US Constitution with the approval by a two-thirds vote in each house of Congress (67, 281) and three-fourth vote by the states (38).” The ninth
This hopefully adds some insight into the use of electric motors, and the principals of them that make these motors work. Such as electromagnetism, binary switches for DC motors, and the selection of a running frequency of a motor through the use of an oscillator.
Electrical motors play an important role in today’s society, from powering domestic appliances like blenders to industrial equipment such as trains. It almost seems impossible to not use an electric motor in our daily lives. In the comfort of our home, electric motors will operate fans, refrigerators, and air conditioners to just name a few. Researchers are constantly looking for new ways to incorporate electrical motors in our lives.
Electrical hazards could include vegetation or equipment fires, electrical burns, or electrocutions to humans or animals. Electrical hazards could take place anywhere near energized conductors or facilities.
As a fireman, I like things to be safe, I like things to be simple, and most of all, I like children to be safe. I am here today to talk to you about electrical hazards and safety measures to avoid getting seriously injured. There is one thing you must always remember, electrical safety always leads to fire safety. You must know that new electrical components are always safer than old worn out ones. Electricity may not look harmful at first glance, although you might be surprised of it's devastating fire power. I am here to talk to you about the different safety precautions to take for each individual hazard. Always remember, electrical safety always leads to fire safety.
The report I am going to write about is to do with electrical safety devices and safety practices which contribute in reducing and eliminate specific risks. The workplace I have chosen to write about is electricians in power stations. The report I am going to write is going to show a clear understanding of electrical safety devices and the improvements of electrical safety devices.
In the early 1900s industrial accidents were commonplace in this country; for example, in 1907 over 3,200 people were killed in mining accidents. At this time legislation and public opinion all favored management. There were few protections for the worker's safety. Today's industrial employees are better off than their colleagues in the past. Their chances of being killed in an industrial accident are less than half of that of their predecessors of 60 years ago. According to National safety Council (NSC), the current death rate from work-related injuries is approximately 4 per 100,000, or less than a third of the rate of 50 years ago. Improvements in safety up to now have been the result of pressure for legislation to promote health and safety, the steadily increasing cost associated with accidents and injuries, and the professionalization of safety as an occupation. When the industrial sector began to grow in the United States, hazardous working conditions were commonplace. Following the Civil War, the seeds of the safety movement were sown in this country. Factory inspection was introduced in Massachusetts in 1867. In 1868 the first barrier safeguard was patented. In 1869 the Pennsylvania legislature passed a mine safety law requiring two exits from all mines. The Bureau of Labor Statistics (BLS) was established in 1869 to study industrial accidents and report pertinent information about hose accidents. The following decade saw little progress in the safety movement until 1877, when the Massachusetts legislature passed a law requiring safeguards for hazardous machinery. In 1877 the Employers' Liability Law was passed. In 1892, the first safety program was established in a steel plant in Illinois, in response to the explosion of a flywheel in that company.
