Page 278: In Rule 410A3 EXCEPTION 4. change the text as follows:
Arc-rated equipment is not necessary for the employee’s head or face when the employee is wearing head protection meeting OSIIA 29 CFR 1910.135 [1148] if the estimated incident energy is less than 9 cal/cm’ for exposures involving single phase arcs in open air less than or 5 cal/cm2 for other exposures. Arc-rated equipment is necessary for the protection of the employee’s head and face and may consist of head protection meeting OSIIA 29 (‘FR 1910.135 and a face shield with a minimum arc ratin? of 8 cal/cm2 if the estimated incident-energy exposure is greater than 9 cal/cm2 and less than 13 cal/cm- for exposures involving single-phase arcs in open air or greater than 5 cal/cm’ and less than 9 cal/cm for other exposures. For exposures involving single phase arcs in open air, the arc rating for the employee’s head and face protection may be 4 cal’em’ less than the estimated incident energy.
Page 279: In Rule 4l0A3 EXCEPTION 5, change the text as follows:
For dc systems with voltages from 50 V to 250 V and 8000 A maximum fault current, in lieu of performing an arc hazard analysis. clothing with a minimum effective arc rating of 5 calcm’ shall be used.
