ARC FLASH STUDIES
In the United States, the NEC (NFPA70), require electrical equipment (such as distribution boards, industrial control panels, meter enclosures, and motor control centers that need inspection, adjustment, repair, or maintenance while energized) to be appropriately marked in order to warn qualified personnel of the Potential Arc Flash Hazard.
The objective of an Arc Flash Potential Hazard Analysis Study is to determine the power level at each of the electrical panels where maintenance is applied. The intention is to define the safe working distances according to the voltage, hazard category and the personal protective equipment to be used by the worker when performing maintenance on a given electrical panel.
With the study of Arc Flash and the adequate dimensioning of the protection equipment, as well as correct personnel training, it is possible to avoid accidents and ensure the workers' safety

Importance of electric arc flash studies
In Mexico, the Official Mexican Standard NOM-001-SEDE-2012 (article 110-16), and in the United States, the NEC (NFPA70) requires electrical equipment such as distribution panels, industrial control panels, meter enclosures, and motor control centers that require inspection, adjustment, repair, or maintenance while energized, be properly marked in the field to warn qualified personnel of the Potential Electric Arc Hazard
Accident prevention: Electric arc studies allow for identifying and evaluating risks associated with electric arc generation, helping to implement preventive measures to avoid severe accidents in the workplace
Improved safety: By understanding the factors that influence the formation and propagation of electric arcs, adequately designed and selected electrical equipment and systems can minimize the risk of incidents and protect personnel safety
Regulatory compliance: Conducting electric arc studies helps to comply with safety requirements established by regulations and industrial standards, ensuring a safe working environment and complying with relevant statutes.
