In The 35000 Degree F Flash That Can Vaporize Copper and Throw Shrapnel at 700mph: Arc Flash Safety , you'll learn ...
- Arc flash energy levels and calculations
- A brief history of NFPA 70E: Standard for Electrical Safety in the Workplace
- The required personal protection equipment (PPE) specified in NFPA 70E
- The required documentation for working on live electrical equipment
Every year more than 2,000 people are admitted to burn centers with severe arc flash burns, and several people die each year due to arc flash incidents. An arc flash is a sustained flow of electrical current through the air that can create a temperature of 35,000 degrees Fahrenheit or 20,000 degrees Celsius in less than one-tenth of a second. A distinctive sound with a noise level of 160 decibels accompanies the flash and the heat is enough to vaporize copper!
All of these numbers and facts should mean a lot to those who work with electrical equipment, since they are the ones who could be exposed to this type of hazard every day in their work environment. Fortunately, OSHA prompted the National Fire Protection Association (NFPA) to develop safety standards that would protect employees during the installation, operation, maintenance, and demolition of electrical equipment and conductors. These safety provisions are specified in NFPA 70E: Standard for Electrical Safety in the Workplace.
In this webinar, we’ll examine key sections of the most recent version of NFPA 70E (the 9th edition of 2012) and discuss its implications. You’ll learn the safety regulations that are meant to protect you and your coworkers on the job and at home, as our discussion takes us far beyond the lockout-tagout provisions of 70E.
This webinar offers an interesting and lively discussion for both experienced engineers and those who are newer to our profession.
