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 insulati
9、ng live-line tools used for energized-linemaintenance 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. Whe
10、n transporting hand-held insulating live-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 fi
