When working during the rainy season, it is important to take precautions against electric shock, lightning strikes, and collapses. 1. To prevent electric shock, the \"three-phase five-wire system\" should be used; bare wires or plastic wires are not permitted, and wires must not be laid along the ground. The distribution boxes should be standardized and weatherproof; electrical components must not be damaged, and it is strictly prohibited to expose them while they are under voltage. Mechanical and electrical equipment should be equipped with grounding or neutral connection protection. Electromechanical equipment and lighting must be equipped with leakage protectors. Second-level protection is implemented. Lighting in humid areas, pipelines, and containers should use a 12V voltage; electrical operators must wear insulated gloves and shoes. 2. To protect against lightning strikes, lightning protection devices should be installed on tower cranes, grid frames, gantry cranes, scaffolds, and other structures that are taller than buildings. 3. Prevent collapse by ensuring proper drainage for scaffolds, A-frame structures, and gantry frames, to avoid settlement and tilting. The sides of foundation pits, trenches, and ditches should be sloped in accordance with regulations, and support should be added to vulnerable areas for temporary reinforcement. Ensure proper drainage at the construction site. As soon as a dangerous situation is detected, the supervisor must immediately order the workers inside the pit to evacuate the area, and work can resume only after the danger has been eliminated. Operators must use a dedicated ladder to go up and down; climbing up or down is strictly prohibited.
