Construction machinery must be inspected and approved by the enterprise's mechanical and electrical equipment management department before entering the site. The safety performance of the equipment and its protective devices must meet relevant safety standards, and a usage permit must be issued. Newly purchased lifting equipment should be checked and accepted by professional personnel to ensure it meets safe operating conditions and is approved by the technical supervisor before use.
When leasing mechanical equipment, the lessor must provide self-inspection reports, certificates, technical documents, and user manuals. Additionally, a safety technical test certificate from a qualified testing agency must be provided. Without these, the equipment cannot be leased or used.
All electromechanical equipment and power tools entering the construction site must be inspected by professional personnel to confirm they meet safety requirements before being put into use. If the site lacks the capability to perform this task, the enterprise’s electromechanical department must organize or commission an authorized inspection agency to conduct the check.
Lifting machinery must have specialized assembly and disassembly plans and safety measures developed by qualified professionals, with all necessary approvals completed before installation.
The installation and disassembly of lifting equipment must be carried out by certified units and trained personnel. Regular maintenance and insulation checks are essential. Equipment that fails safety inspections or cannot be repaired must be immediately taken out of service and disposed of properly.
The construction site must ensure that all mechanical and electrical equipment has access to stable roads, solid foundations, proper power supply, and sufficient space for operation and maintenance. Adequate lighting must be provided for night work to ensure safety.
The working area for electromechanical equipment must comply with safety regulations. The site should be level, unobstructed, and have enough room for operation and maintenance. No materials or debris should be placed in the working area. If fire protection is required, the site must meet fire safety standards.
The foundation or base of construction and power machinery must be stable and meet the manufacturer’s specifications or design requirements.
Electrical systems for electromechanical equipment and small power tools must follow industry standards and be installed, removed, and maintained by qualified professionals.
Equipment management should follow the "three sets" principle: set up, assign, and manage. Only trained personnel can operate such equipment. Before using small power tools, users must receive safety training and be familiar with the procedures.
Operators must wear appropriate personal protective equipment (PPE). Clothing should be secure, with sleeves and hems fastened. Female workers must keep their hair tucked inside their helmets.
Before starting any equipment or using small power tools, operators must inspect the power cords and safety guards. Equipment with damaged cords or faulty safety features must not be used until repaired by professionals. At the end of the shift, the power should be turned off, and the switch box locked. Handheld tools should be stored in a dry, secure location.
Before each use, all machinery, instruments, and tools must be checked to ensure they are in good condition. If trial runs are required, they must be conducted according to the manufacturer's instructions and confirmed as safe before operation.
Construction and electrical equipment, as well as small power tools, must not be operated under abnormal conditions or overloaded. If any issues arise during operation, the equipment must be stopped immediately for inspection. Never attempt to clean or repair while the machine is running. Keep hands and heads away from moving parts. Repairs must be performed by qualified professionals following the original manufacturer's guidelines.
New machines, or those undergoing overhaul or modification, must be operated according to the factory manual and this regulation. Overloading or altering the intended use is strictly prohibited. Instruments and safety devices requiring regular inspection must be tested by accredited agencies; otherwise, they cannot be used.
Cranes must maintain a safe distance from overhead power lines, as specified in Table 4.0.17. When passing under power lines, the crane boom should be lowered to avoid contact.
Electrical equipment and wiring must be well insulated, and wires should not be tied to metal objects. All electric motors must comply with the “one machine, one brake, one leakage, one box†rule, with non-conductive metal enclosures properly grounded or connected to zero. In case of power cuts, shutdowns, or breaks, the power must be turned off, and the switch box locked.
The voltage of line lamps must not exceed 36V, and rubber cables must be used. A safety voltage transformer must be employed. In wet areas or metal containers, the lamp voltage must not exceed 12V.
Pressure vessels must be equipped with safety valves and pressure gauges, and must be protected from impacts and exposure. Oxygen cylinders must be kept away from oil, and acetylene generators and LPG cylinders must have anti-backfire devices to prevent accidents.
