The level of energy from an arc flash is a function of distance from the arc flash, clearing time of <br />fault (how quickly the fuse or disconnection device reacts and opens the circuit) and magnitude <br />of fault current available. These three variables make a detailed engineering analysis very <br />difficult and only generalized conclusions can be made. <br />The dilemma we have is there are three codes (NESC, NEC, and NFPA) that do not agree, yet <br />the code we fall under excludes the area that contains the real hazards, an imperfect engineering <br />analysis with only general conclusion. The end result is that we may have to change our work <br />practices and the protective clothing we provide to our employees. <br />Attached please find the following information for your review: <br />1) Arc flash analysis completed by USG. <br />2) Copy of our current Fire Retardant Clothing Policy. <br />3) Section 31 of our Employee Handbook titled Employee Clothing. The clothing we now <br />provide satisfies Hazard Risk Category 1 per the arc flash analysis. <br />Staff is currently reviewing our Fire Retardant Clothing Policy and work rules and will make a <br />recommendation at our meeting. <br />
