Available incident energy and the corresponding working distance.You will notice the the Z462 standard identifies the exact requirements as the NFPA 70E but makes one addition – (d) date of the hazard analysis.Įlectrical equipment such as switchboards, panelboards, industrial control panels, meter socket enclosures, and motor control centers (MCCs) that are in other than dwelling units and that are likely to require examination, adjustment, servicing, or maintenance while energized shall be field marked with a label containing all the following information: NFPA 70E standard with minor alterations to better reflect the Canadian workplace, and coincide better with other existing CSA electrical standards.Ĭlause 4.3.5.4 in Z462-12 details the arc flash equipment labeling requirements. The CSA Z462 is essentially a direct copy of the U.S. If you would like more information you can visit the IEC website directly.Ĭanadian Standards Association(CSA) Z462-12 and North American standards, it is hard to make a direct comparison of the content. The electrical systems and design practices in Europe are so different from U.S. is familiar with, and is followed throughout Europe and much of the rest of the world. IEC 60298 is the equivalent of NFPA and IEEE standards that the U.S. The IEC is a non-profit institution much like the NFPA and IEEE in the U.S., that is responsible for establishing electrical standards throughout the world. IEC stands for International Electrotechnical Commission (IEC). IEC standards are used predominantly in Europe and have trickled into many other parts of the world. OSHA standards basically tell you what you must do, and the NFPA 70E tells you how to do it. The NFPA 70E has not been formally adopted by OSHA at this time, but there is a great correlation and relationship between the standards. The NFPA 70E clearly calls out the hazards of Shock, Electrocution, Arc Flash, and Arc Blast and gives direction on how to properly protect workers from each of these standards. This is a document that is much more concerned with protecting workers through safe work practice not necessarily just proper design and installation. Installations used by the electric utility, such as office buildings, warehouses, garages, machine shops, and recreational buildings that are not an integral part of the generating plan, substation, or control center.Īs you can see from this scope of the standard, it is much different that the NEC. Installation of conductors and equipment that connect to the supply of electricity. 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: 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. It is also not a part of the NEC previously mentioned, but is instead a self-contained document.Ĭovered. This is a document that is published by the NFPA and is not an OSHA document. NFPA 70E is the Standard for Electrical Safety in the Workplace.
