Electrical Safety Code Manual A Plain Language Guide to National Electrical Code, OSHA, and NFPA 70E by Kimberley Keller | PDF Free Download.
We have been manipulating power since the time of the caveman. About half a million years ago, mankind mastered fire. The energy source was easy, even for them, to understand; if you touched it, you would get burned.
A 1000 years later, the ancient Greeks discovered that rubbing fur on amber caused a spark of energy, and by the seventeenth century, the differentiation between positive and negative currents was discovered.
In the year 1600, an English physician named William Gilbert coined the term electric, from the Greek elektron, to identify the force that certain substances exert when rubbed against each other. It was a great leap forward from rubbing two sticks together to generate enough heat to make fire.
Then, in 1800, an Italian physicist named Alessandro Volta discovered that certain chemical reactions could produce electricity and he created the first transmission of electricity by linking positively-charged and negatively-charged connectors.
Volta found that he could force an electrical charge, or voltage, through the connectors. Over time, higher voltages were generated and a new discovery was made; electrical current could cause burns, severe injury, and even death.
It could start fires, it could cause materials to arc or explode. It quickly became apparent that electricity had both infinite possibilities for society and unrestrained potential to cause extreme damage.
In order for us to be able to survive using electricity, we had to develop a means of safely working with electrical power, wiring, conductors, generators, and other related equipment and components.
Perhaps you have been a licensed electrician for years and maybe you’ve received a little jolt now and then, but nothing serious. But the reality is that electrical injuries cause about 1000 deaths annually in the United States and are responsible for about 5% of burn center admissions.
While you may have escaped serious injury over the years, the fact is that electrical injuries rank as the fifth most common cause of occupational fatalities.
The best way for anyone who works with electrical systems to prevent injury to themselves or others, as well as damage to property, is to practice proven electrical safety methods. Electrical safety programs in the workplace not only decrease the incidence of injury but also protect companies and their employees from the financial ramifications of a work-related accident.
In the case of the electrical industry, safety is critical and the codes and regulations that determine safe practices are both diverse and complicated. Employers, electricians, electrical system designers, inspectors, engineers, and architects must all comply with safety standards listed in the National Electrical Code, OSHA and NFPA 70E.
Unfortunately, the publications that list these safety requirements are written in very technically advanced terms and the average person has an extremely difficult time understanding exactly what they need to do to ensure safe installations and working environments.
This book will tie together the various regulations and practices for electrical safety and translate these complicated standards into easy-to-understand terms. Even veteran master electricians will find it informative and gain a new understanding of how to minimize their exposure to possible injury.
After all, you’re worth it.
