Regarding welding operations
Thread Content
In welding operations at oil depots, is it necessary to keep the welding cable and the ground wire together? Are long-distance jumps a risk?
Welding within the oil depot area: long-distance bridging may lead to poor contact and sparking, making it difficult to monitor.
Yes, making long-distance connections can easily cause sparks. As you said, working with fire in a fuel depot carries a high risk of accidents
Long-distance bridging operations are not permitted within the oil depot
There are strict regulations regarding hot work involving flammable and explosive materials. When carrying out such work in an oil depot, both sets of rules must be followed; the work cannot be carried out over long distances to avoid creating electrical circuits. For safe hot work, two things are necessary: first, the isolation of the materials, and second, the isolation of the electrical circuits. Therefore, it is not allowed to create loops over long distances or to have poor contacts that cause sparking.
