First, here is the good news. We all like happy and successful stories. Our electrical industry has seen a substantial decline in electrical injuries in the last 10 years. This is due to: 1. Increase in general safety awareness; 2. NFPA 70E and the people behind 70E; 3. Attorneys and large court settlements. As good as 70E is, it is difficult to understand and implement under the vast number of variable site conditions we eperience in the field. It is the task of each type of industry and each site to adopt the excellent provisions of 70E to its electrical hazards. No one will question that zero injuries is the goal of safe electrical work practices. It is the journey to this goal that provides the challenge. The arc-flash calculator presented here can be part of that journey. It is designed to give you, the worker, a tool that can be used at the job site to assist in determining what PPE is needed. This is in addition to your daily Job Hazard Analysis (JHA) and Energized Work Permit (EWP) and to be used in conjunction with them. It is not easy and requires experienced, trained personnel.
