1.1 This guide provides information for the selection, care, and use of arc protective blankets for personnel protection.

1.2 This guide covers positioning and securing arc protective blankets (tested to Test Method F2676) and channeling the thermal, ballistic, and concussive forces generated by an arc flash event using arc protective blankets.

1.3 This guide describes the use of the arc protective blanket to maximize its protective effectiveness to workers exposed to energized electrical equipment where complete de-energizing of the work zone cannot be achieved or for low-risk exposures with sufficient arc flash incident energy to warrant secondary protective means in the event of an arc flash.

1.4 The values stated in SI units are to be regarded as the standard. See IEEE/ASTM SI-10.

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use.
