Job Site Procedures4.1 Field Care, Handling, and StorageWhen not in use,hand-held insulating live-line tools should be stored where theywill remain dry, clean, and where they are not subject to abuse.Hand-held insulating live-line tools used for energized-l
8、inemaintenance should not be laid directly on the ground to avoidcontamination or wetting. Hand-held insulating live-line toolsshould be placed on clean, dry tarpaulins, on moisture-proofblankets, on tool racks, or stick bags, or leaned against drysupports. When transporting hand-held insulating liv
9、e-linetools, ventilated containers should be provided to preventdamage to the surfaces of them, or they should be mounted onracks in trucks or trailers. These racks should be well paddedand so constructed that the hand-held insulating live-line toolsare held firmly in place to prevent abrasive or bu
