The National Board of Boiler and Pressure Vessel Inspectors is composed of chief boiler and pressure vessel inspectors representing states, cities, and provinces enforcing pressure equipment laws and regulations. Created to prevent death, injury and destruction, these laws and regulations represent the collective input of National Board members.〔(【引用サイトリンク】 publisher = National Board of Boiler and Pressure Vessel Inspectors )〕 During the past ten years, over six million pressure equipment inspections were performed in North America. Of that total, there were more than 556,000 violations, or more than 556,000 potential accidents that were prevented: almost one out of every ten pieces of equipment inspected. For the general public, the importance of thoroughly trained and specially commissioned inspectors is of critical significance: every person in the civilized world comes within close proximity of pressure equipment several times each day. == A Short History == Steam drove the Industrial Revolution during the mid-19th century. At this point in history, conversion of water was considered both good and bad: good in the sense it powered industrial progress, and bad in that boilers used in the conversion process employed new and unproven technology. According to the American Society of Mechanical Engineers (ASME): :''“For want of reliably tested materials, secure fittings and proper valves, boilers of every description, on land and at sea, were exploding with terrifying frequency…Engineers could take pride in the growing superiority of American technology but they could not ignore the price of 50,000 dead and two million injured by accidents annually.”'' As catastrophic casualties continued into the early 20th century, the ASME developed its boiler code in 1915. While the code provided a solid reference of construction standards, it lacked an important component: the authority to regulate. This was complicated by existence of local and state jurisdictions having their own codes and standards. The result was a patchwork of confusion having no basis in consistency. On December 2, 1919, Ohio Chief Inspector Carl Myers met with chief inspectors from other jurisdictions to discuss creation of a board of inspector representatives from each of the existing jurisdictions. Hence, the genesis of The National Board of Boiler and Pressure Vessel Inspectors. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「National Board of Boiler and Pressure Vessel Inspectors」の詳細全文を読む スポンサード リンク
