Arc Flash Labels
Arc Flash Labels
Arc Flash is a short circuit through air from one exposed live conductor to another conductor or to ground.
Most electrical injuries occur because of arc flash and not from electrical shock. It’s estimated that five to ten arc flash explosions happen in the US each day. The costs are staggering both in terms of physical injury and loss of life, but also include costs associated with downtime, lost revenue, loss of product, equipment damage and OSHA citations and fines.
OSHA 1910.132 (d) & 1926.28 (a) state that the employer is responsible to assess hazards in the workplace and select have and use the correct Personal Protective Equipment (PPE) and document the assessment.
NFPA 70E, Part II, 2-1.3.3. “Flash hazard analysis shall be done before a person approaches any exposed electrical conductor or circuit part that has not been placed in an electrically safe work condition.”
Arc Flash Label Compliance
Employers are responsible for complying with the 2002 NEC 110.16 which states, “Switchboards, panelboards, industrial control panels, and motor control centers 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 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.”
Arc Flash and Shock Hazard Labels
Label information should include equipment’s flash protection boundary, incident energy level and the required PPE necessary to safely work on the equipment.
OSHA recognizes the National Fire Protection Agency (NFPA) “NFPA 70E” as setting the standard for arc flash safety in the workplace. Click to order NFPA 70E, “Standard for Electrical Safety in the Workplace” which is available for purchase at the NFPA online catalog website.
ArcCalc calculates the incident energy and arc flash boundary for any point in a power system and automatically determines trip times from the protective device settings. Incident energy, arc flash boundaries and PPE are calculated following the NFPA 70E and IEEE 1584 standards.
Arc Flash labels can be printed on the Precision 343P to comply with NEC 110.16 arc flash labeling requirements. Create custom arc flash labels with user-defined logos, text, comments and field placement.
