Critical power: Thoughtful arc flash mitigation, reduction and proper design
1 AIA CES APPROVED LU/HSW AVAILABLE FOR ATTENDEES UPON SUCCESSFUL COMPLETION OF AN EXAM.
Electrical engineers must understand the codes, standards and design requirements when designing to mitigation arc flash problems. Many factors go into mitigating the danger that electrical workers face; engineers must thoughtfully design systems to reduce and mitigate these incidents in the field.
De-energizing electrical equipment results in the safest conditions for electrical workers. However, in most industry applications, de-energizing the electrical system may not be practical and in some cases, may result in an even greater safety hazard.
Reducing arc flash to electrical personnel is an evolutionary process. No individual solution will eliminate all of the hazards of working on energized equipment.
Owners, facility managers, engineers and contractors can all contribute to providing a safer place for personnel to work. The process all starts with safe equipment and engineering design, followed by proper installation of equipment and proper training and maintenance procedures.
Learning objectives:
- Understand the various codes and standards related to arc flash mitigation design, such as NFPA 70E: Standard for Electrical Safety in the Workplace and IEEE 1584.1, plus other industry practices.
- Learn design techniques, including pros and cons that will reduce arc flash incident energy.
- Know that mitigating arc flash through design is paramount to electrical safety.
- Review design scenarios in which arc flash problems were removed.
