Arc Flash Protection Marking as Required by
the National Electrical Code
Flash Protection Marking
Requirement
The flash protection marking requirement was initially established in 2000 by
The National Fire Protection Association (NFPA 70E), Standard for Electrical
Safety Requirements for Employee Workplaces. NFPA 70E applies to workers
who install, maintain, or repair electrical systems.
In 2002, NFPA 70, The National Electrical Code (NEC) added the Article
110.16, and reinforced the flash protection marking of equipment. The 2002
version of the article is stated below.
110.16 Flash Protection
Switchboards, panelboards, industrial control panels, and MCCs that
are in other than dwelling occupancies and are likely to require
examination, adjustment, servicing, or maintenance while energized
shall be field marked to warn qualified persons of potential electric arc
flash hazards. The marking shall be located so as to be clearly visible to
qualified persons before examination, adjustment, servicing, or
maintenance of the equipment.
FPN No. 1: NFPA 70E-2000, Electrical Safety Requirements for
Employee Workplaces, provides assistance in determining severity of
potential exposure, planning safe work practices, and selecting personal
protective equipment.
FPN No. 2: ANSI Z535.4-1998, Product Safety Signs and Labels,
provides guidelines for the design of safety signs and labels for
application to products.
As Arc Flash Technology emerges, new developments have caused changes to
arc flash criteria. For example, in 2004, the NFPA 70E was reissued in a
completely new format along with changes reflecting new developments. The
NEC is revised every three years and the NFPA 70E is revised every four years.
Use the latest editions of the NEC and NFPA 70E in establishing potential
electric arc flash hazards and arc flash marking.
