Standard Guide for Selection, Care, and Use of Arc Protective Blankets

Importancia y uso:

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 This guide 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.
