Construction machinery must be inspected and approved by the enterprise’s mechanical equipment management department before entering the site. The mechanical and electrical safety performance, as well as all safety protection devices, must meet relevant safety standards. A permit must be issued before it can be used. Newly purchased lifting equipment should be checked and accepted by professional technical personnel to ensure it meets safe usage conditions and is approved by the company's technical supervisor before being put into operation.
When leasing mechanical equipment, the lessor must provide a self-inspection report, certificate, technical documents, and the factory manual. Additionally, a safety technical test certificate from an accredited testing agency is required. Otherwise, the equipment cannot be leased or used.
All electromechanical equipment and power tools entering the construction site must be inspected by qualified personnel to confirm they meet safety requirements before use. If the site lacks the capability for such checks, the enterprise’s electromechanical management department must organize or commission a legal inspection agency to conduct the tests.
Lifting equipment must have detailed assembly and disassembly plans and safety measures prepared by professionals. These plans must go through proper approval procedures before implementation.
The installation and disassembly of lifting equipment must be carried out by certified units and professionals. Regular maintenance and inspections of electrical insulation are essential. Equipment that fails safety checks and cannot be repaired must be immediately taken out of service and disposed of properly.
The construction site must ensure that mechanical and electrical equipment has the necessary conditions for safe operation, including stable roads, proper foundations, sufficient power, and a secure workspace with adequate lighting for night work.
The workplace for electromechanical equipment must meet safety requirements. The site should be level, unobstructed, and have enough space for operation and maintenance. Work channels must remain clear, and no materials or debris should be stacked nearby. If fire safety regulations apply, the workplace must comply with those requirements.
The foundation or base of construction and power machinery must be stable and meet the manufacturer's specifications or design requirements.
Electrical power used for electromechanical equipment and small tools must comply with regulations and standards, and must be installed, removed, and maintained by qualified professionals.
Electromechanical equipment management should follow the principle of “assigning personnel, assigning positions, and setting up equipment.†It is strictly prohibited for unqualified individuals to operate such equipment. Before using small power tools, users must receive safety training and understand the operating procedures.
Operators of electromechanical equipment and small power tools must wear appropriate personal protective equipment. Operators' clothing should be snug and not loose, with sleeves and hems properly fastened. Female workers must keep their hair contained within their work caps.
Before operating any equipment or using small power tools, operators must check the power cords and safety guards. Equipment with damaged cords or faulty safety devices must not be used until they are repaired or replaced by professionals. At the end of the shift, the power should be turned off, and the switch box locked. Small hand-held tools should be stored in a designated storage area.
Before starting work, all machinery, instruments, and tools must be inspected to ensure they are in good condition. If trial runs are required, they should be conducted according to the regulations and confirmed before use.
Construction machinery and electrical equipment, as well as small power tools, must not be operated when faulty or overloaded. Any abnormalities during operation should lead to immediate shutdown and inspection. Maintenance or cleaning while the equipment is running is strictly prohibited. No part of the body should be extended into the mechanical movement area. Repairs must be performed by qualified professionals following the manufacturer’s guidelines and relevant standards. Unauthorized parts or modifications are not allowed.
New machines, machines undergoing overhaul, or those undergoing technical upgrades must be operated and used according to the factory manual’s technical specifications, load capacity, and usage conditions. Overloading or changing the intended use is strictly prohibited. Instruments and safety devices requiring regular inspections must be tested by accredited agencies; otherwise, they cannot be used.
Cranes must not be operated near overhead power lines. The minimum safe distance between any part of the crane and the power line must meet the requirements specified in Table 4.0.17. When passing over power lines, the crane boom should be lowered.
Electrical equipment and wiring must have proper insulation. Cables must not be tied to metal objects. All electric motors must meet the "one machine, one brake, one leakage, one box" requirement, and non-conductive metal enclosures must be grounded or connected to zero as required. In case of power failure, work stoppage, or absence, the power must be turned off and the switch box locked.
Work lamp voltage must not exceed 36 volts. Power cables should use rubber flexible cables, and an auto-transformer for safety voltage must be used. When working in wet areas or metal containers, the lamp voltage must not exceed 12 volts.
Pressure vessels must be equipped with safety valves and pressure gauges, and should avoid exposure and impact. Oxygen cylinders must be protected from oil contamination. Acetylene generators and liquefied petroleum gas systems must have anti-backfire safety devices.
