This article supplies a safe-approach reference developed through years of experience working with engineers and electricians on their arc flash hazard projects. The viewpoints expressed in this paper are provided as a guide to industry, recognizing that the NEC, NFPA, and OSHA set the standards but do not cover the myriad of questions associated with labeling the different types of electrical equipment in industry.
Many of these misconceptions are due to a lack of thorough understanding of the laws, regulations, and standards that apply to Arc-Flash Hazard Assessments. The document focuses on some of the fundamentals of electricity, electrical wiring, electric tools, protective methods and devices, and related work methods and safe practices in the construction industry.
After viewing this program, electrical workers and supervisors will have an understanding of those responsibilities and be convinced that always following electrical safe work practices and procedures is the only way for electrical workers to stay safe. It does not include every change made, and much of the language is paraphrased due to space limitations. Since the NFPA Standards Council has not formally approved the final document, there is always the possibility of additional changes.
Therefore, always refer to the final approved version when it is published. See video. It is provided with the understanding that the publisher is not engaged in rendering legal, accounting or other professional services.
Since the contact was with one phase, the actual contact voltage to ground was 7. When a Project Safety Representative PSR observed the occurrence, and saw sparks emanating from under the excavator at the time it made contact with the 7. The PSR stepped out of his truck and moved toward the excavator. Fortunately the excavator driver had backed his equipment away from the power line prior to the PSR arrival.
As he pulled on the cable, a bare spot in the lead came into contact with his unprotected, sweaty skin at the base of his neck and gave him an electric shock. Electrical Safety Rules Pdf Download Electrical Safety Measures Pdf And clarification of basic electrical safety for individuals who have little or limited training or familiarity with the field of electricity.
