Avoid accidents and OSHA fines with the 2009 NFPA 70E: Standard for Electrical Safety in the Workplace!
Shock, electrocution, arc flash, and arc blast are responsible for hundreds of worker deaths and thousands of injuries per year in the U.S. alone. Save lives with NFPA 70E: Electrical Safety in the Workplace, the standard developed for OSHA that details the "hows" behind compliance with OSHA 1910 Subpart S and OSHA 1926 Subpart K.
The 2009 edition is revised to recognize new hazards and increase safety on the job.
Personal Protective Equipment (PPE) protects personnel and can significantly reduce the risk of injury in an arc flash. To help engineers calculate incident energy - the first step in determining the correct type of PPE for a given task - a new Annex D in the 2009 NFPA 70E consolidates all equations, adds new tables, and offers more options to detailed calculations. For example, a new utility table derived from the National Electrical Code helps utility and industrial plant workers calculate PPE based on voltage and fault current data.
Improved work practices reduce risks:
- A new requirement for Fire Rated clothing for H/R Category 1 precludes the use of cotton clothing. This change reduces the risks for second-degree thermal burns.
- An expanded Table in Article 130 covers added tasks such as thermographic imaging, and new equipment including arc-resistant switchgear.
- Added Article 350 provides first-time requirements for the protection of electrical personnel in R&D labs.
- A new exception verifies that 240 V and less power systems fed by a single transformer less than 125 kvs no longer require an arc flash hazard analysis.
- Expanded requirements for multi-employer relationships address potential areas of oversight, and improves contractor communication about electrical hazards.
- New recordkeeping requirements for training and safety program audits answer OSHA's need for records and ensure data is available when you need it.
Other changes expand your know-how:
- Easy-to-see shading identifies new or revised Standard text.
- Annex F clarifies the Hazard/Risk evaluation procedure and provides sample worksheets.
- A flow chart in Annex J helps users determine the need for an Energized Electrical Work Permit.
- Annex M helps workers and supervisors evaluate layering of PPE.
- Annex N explains safe work practices near overhead and underground lines.
Engineers, designers, risk managers, maintainers, safety directors, contractors, and owners need the 2009 NFPA 70E to improve worker safety and avoid citations, rising insurance fees, and increased worker's comp costs.
This edition of NFPA 70E, Standard for Electrical Safety in the Workplace, was prepared by the Technical Committee on Electrical Safety in the Workplace and released by the Technical Correlating Committee on National Electrical Code, and acted on by NFPA at its June Association Technical Meeting held June 2-5, 2008, in Las Vegas, NV. It was issued by the Standards Council on July 24, 2008, with an effective date of September 5, 2008, and supersedes all previous editions.
This edition of NFPA 70E was approved as an American National Standard on September 5, 2008.
Excerpt from the Foreword
Chapter 4 of NFPA 70E was therefore intended to serve a very specific need of OSHA and is in no way intended to be used as a substitute for the National Electrical Code. Omission of any requirements presently in the National Electrical Code does not in any way affect the National Electrical Code, nor should these requirements be considered as unimportant. They are essential to the National Electrical Code and its intended application, that is, its use by those who design, install, and inspect electrical installations. NFPA 70E, on the other hand, is intended for use by employers, employees, and OSHA.
For 2009, over 1300 proposals and comments were reviewed by the committee upgrading requirements throughout the document. Among the most significant, Chapter 4 has been deleted because it was a duplicate of National Electrical Code installation requirements. Since the National Electrical Code and NFPA 70E are on different revision cycles there was always the risk that the contents of Chapter 4 of NFPA 70E were not up to date with the National Electrical Code. Article 350 was added for R&D facilities. Other changes include significant revisions to Annexes D, E, F and J and the addition of Annexes M, N, and O.
