Standard Guide for Selection, Care, and Use of Arc Protective Blankets
SIGNIFICANCE AND USE
5.1 This guide provides positioning, installation, and anchoring techniques that may be used to arrange arc protective blankets to confine or divert the energies found from a fault that may include plasma arcing, pressure wave, and projectiles.
5.2 Arc protective blankets may be used in an electrical application to confine or divert energy away from a work zone for electrical or other workers who may be exposed to an electric arc in the event of an equipment or conductor failure.
5.3 This guide provides information for working around cables, splices, and any equipment components that have historical failures deemed to require additional protection or engineering controls, which could benefit from added protection provided by an arc protective blanket.
5.4 This guide is designed for electrical engineers and qualified installers of arc protective blankets.
5.5 The practice is limited by the blanket protective value, the sturdiness of the installation, and the engineering assumptions of the hazard assessment.
5.6 These blankets do not typically provide dielectric protection.
5.7 These blankets do not eliminate the need for arc-rated PPE but may reduce the level of the hazard in some installations.
SCOPE
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. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
