NFPA 70E Standard for Electrical Safety in the Workplace®
NFPA 70E 车间电气安全标准
90.2 Scope.
(A) Covered. This standard addresses electrical safety-related work practices for employee workplaces that are necessary for the practical safeguarding of employees relative to the hazards associated with electrical energy during activities such as the installation, inspection, operation, maintenance, and demolition of electric conductors, electric equipment, signaling and communications conductors and equipment, and raceways. This standard also includes safe work practices for employees performing other work activities that can expose them to electrical hazards as well as safe work practices for the following
(1) Installation of conductors and equipment that connect to the supply of electricity
(2) Installations used by the electric utility, such as office buildings, warehouses, garages, machine shops, and recreational buildings that are not an integral part of a generating plant, substation, or control center
(B) Not Covered. This standard does not cover safety-related work practices for the following
(1) Installations in ships, watercraft other than floating buildings, railway rolling stock, aircraft, or automotive vehicles other than mobile homes and recreational vehicles
(2) Installations underground in mines and self-propelled mobile surface mining machinery and its attendant electrical trailing cable
(3) Installations of railways for generation, transformation, transmission, or distribution of power used exclusively for operation of rolling stock or installations used exclusively for signaling and communications purposes
(4) Installations of communications equipment under the exclusive control of communications utilities located outdoors or in building spaces used exclusively for such installations
(5) Installations under the exclusive control of an electric utility where such installations
a. Consist of service drops or service laterals, and associated metering, or
b. Are located in legally established easements or rights-of-way designated by or recognized by public service commissions, utility commissions, or other regulatory agencies having jurisdiction for such installations, or
c. Are on property owned or leased by the electric utility for the purpose of communications, metering, generation, control, transformation, transmission, or distribution of electric energy, or
d. Are located by other written agreements either designated by or recognized by public service commissions, utility commission, or other regulatory agencies having jurisdiction for such installations. These written agreements shall be limited to installations for the purpose of communications, metering, generation, control, transformation, transmission, or distribution of electric energy where legally established easements or rights-of-way cannot be obtained.
These installations shall be limited to federal lands, Native American reservations through the U.S. Department of the Interior Bureau of Indian Affairs, military bases, lands controlled by port authorities and state agencies and departments, and lands owned by railroads.

Lives depend on you! Protect your personnel from electrical hazards and meet the highest standard for electrical safety with the 2012 edition of NFPA 70E®.
Workplace safety in the United States is evolving due to better awareness and implementation of NFPA 70E Standard for Electrical Safety in the Workplace®. Yet hundreds of deaths and thousands of disabling injuries still occur each year due to shock, electrocution, arc flash, and arc blast -- and most could be prevented through NFPA 70E compliance. The 2012 NFPA 70E responds to the challenges, making it easier to ensure an electrically safe working area and comply with OSHA 1910 Subpart S and OSHA 1926 Subpart K.
Get new ways to calculate risks and mitigate hazards.
Originally developed at OSHA's request, NFPA 70E responds to new information about the effects of arc flash, arc blast, and direct current (dc) hazards, and recent developments in electrical design and Personal Protective Equipment (PPE).
Coverage of direct current hazards is the first of its kind in the U.S.
The rising demand for alternative energy systems such as photovoltaic and wind power present greater dc shock and arc flash hazard exposures to workers. To protect personnel, NFPA 70E includes a new shock protection boundary, hazard/risk table, and incident energy calculation for direct current systems. Revised Article 320 focuses on safe work practices for stationary batteries and battery rooms, such as those used by alternative energy systems.
Make hazard/risk assessments and select proper PPE.
· Revised requirements delineate the essential difference between "risk assessment" and "hazard identification." Supporting information is in revised Annex F.
· Hazard/risk tables are expanded to include electrical system characteristics and arc-flash protection boundaries.
· The 2* designation has been eliminated to clarify that all H/R Category 2 tasks require full-head PPE.
· Change on "layering" for a combined arc-rating permits the use of arc-rated garments only.
· Clarified text for arc flash hazard warning labels
Give your employees the know-how they need to be electrically safe on the job!
Training and audit-related revisions impact your company's electrical safety program. The 2012 NFPA 70E explains when the energized work permit (EWP) is required and what it should contain; requires emergency procedure instruction on AEDs (Automatic External Defibrillators), adds a new three-year maximum interval for employee training and documentation of content, and more. This edition also contains new information about implementing NFPA 70E within the framework of ANSI/AIHA Z10 and other health and safety management standards.
Order your copy of the new NFPA 70E, the Standard that's changing the way America works!
If you're responsible for ensuring workers are protected from shock and arc flash hazards, order NFPA 70E now to protect personnel and your reputation for safety. Contractors; risk managers; engineers; apartment, commercial, and retail building managers; and owners all have a stake in ending electrical-related accidents, liability, and loss.
