Arc Flash Protection

Arc Flash Protection

Our arc flash protection incorporates technologically advanced fabrics and materials to provide true Arc rated protection. In full compliance with all aspects of NFPA70E-00, ASTM F1506-2000 and OSHA 29CFR 1910.269 standards. each product comes with a certificate of compliance with the electrical standards. Flashguard hoods provide full head arc protection with a window Arc-X resin with permanent anti-fog coating for excellent visibility & arc flash protection. Coats and bib-overalls compliment the hoods to provide a full system of protection.

Arc flash safety for the toughest job

Meet new OSHA Arc Flash requirements 1910.335 safeguards for personnel protection (1) use of protective equipment (2) Personal protection equipment (i) Employees working in areas where there are potential electrical hazards shall be provided with, and shall use electrical protective equipment that is approriate for the specific parts of the body to be protected and for the work to be performed.

The arc flash protection boundary is based on voltage, available short-circuit current and predicted fault duration. The NFPA 70E provides THREE acceptable methods of determining arc flash protection boundary:

Simplified Table 220.2(B)(2)©, 220.6 (B) (9)

Analysis based on NFPA 70E Annex B

Analysis based on IEEE 1584 All of the known methods have some limitations.

The tables provided by NFPA may be easy to use but they are based on typical equipment and systems and are only approximations. Detailed analysis yields different results than the tables do. Therefore, whatever standard you use, it is necessary to understand its limitations. Evaluate using multiple methods and compare the results to determine the approach that is most appropriate for your facility.

A preventive maintenance program on protective devices is recommended as part of the arc flash program. All arc flash calculations require the arc clearing time in order to determine incident energy and establish the flash protection boundary. The clearing time is derived from the engineering coordination study based on what the protective devices are supposed to do. If maintenance and testing is not performed it could result in extended clearing times, unintentional time delays, open or shunted current transformers, open coils or dirty contacts. All of these factors could cause the results of flash hazard analysis to be inaccurate-causing the flash protection boundary to potentially be inaccurate. This could also affect the recommendations for the proper PPE. It is recommended that facilities adopt NFPA 70B Recommended Practice for Electrical Equipment Maintenance.
