1.Operator Qualification Certification: For the first time, a full-process requirement of "training - assessment - certification - re-evaluation" is clearly defined. Operators must pass a specialized assessment either on equipment type or load capacity (one of the two options), and undergo competence re-evaluation every 2 years. Enterprises will face a maximum fine of $250,000 for unqualified operation.

2.Enhanced Equipment Inspection: A new clause on "mandatory inspection after tipping" is added. Any crane that has tipped over must undergo a comprehensive inspection by a certified engineer and obtain an inspection report before being put back into service (such accidents have caused 93% of crush-related fatalities). Routine inspections must focus on verifying the deceleration rate of the braking system (emergency braking ≥ 0.6m/s²) and the alignment accuracy of gearbox shafts (deviation ≤ 0.1mm/m).

3.Ground and Stability Requirements: On the basis of "solid and level ground", quantitative testing of ground bearing capacity is required (dynamic load ≥ 1.2 times the equipment's self-weight). After extending the outriggers, a level must be used for calibration, and the inclination must not exceed 0.5°.

4.Clearance and Electrical Safety: While maintaining the 10-foot safety distance from power lines, a new "high-voltage area early warning" mechanism is added. When there are power lines with a voltage of 10kV or above within the operation radius, an insulation supervisor must be assigned.

5.New Load Management Regulations: Operators must use an OSHA-certified intelligent load monitoring system that displays the real-time ratio of current load to rated load. The system will automatically trigger emergency braking in case of overloading, and any modification of load limit parameters by any means is prohibited.

6.Key Component Management: The friction brake of the hoisting mechanism must have a continuous holding capacity of 1.5 times the rated load. Wire ropes must comply with the latest ISO 16625 standard and be replaced immediately if the number of broken wires exceeds 3 per strand or the diameter wear reaches 10%.

1. Digital Risk Assessment: Use the safety risk assessment APP recommended by OSHA to conduct quantitative scoring for 6 types of risks, including electrical hazards, ground settlement, and falling objects (a score of ≥ 80 requires the development of a specialized plan).

2. Upgraded Protective Equipment: In addition to basic equipment, personnel working at heights must be equipped with intelligent safety belts compliant with ISO 23778 (with fall alarm function), and electrical operations must use insulating gloves with an insulation level of ≥ Class 00.

3. Standardized Signal System: Adopt a triple confirmation mechanism of "hand signals + wireless intercom + video monitoring". Signalmen must obtain CMAA signal certification, and 360° full-view cameras must be installed in areas with limited visibility.

4. High-Risk Operation Control: When lifting molten metal in the metallurgical industry, a dual electronic control system must be used. Multi-layer winding of wire ropes is prohibited, the gap of anti-derailment devices must be ≤ 8mm, and the drum must be equipped with a breakage protection device (load-bearing capacity ≥ 2.5 times the rated load).

5. Electrical System Protection: Upgrade the "fail-safe" system in accordance with CMAA requirements. In case of a circuit short circuit, non-critical circuits will be automatically cut off to maintain normal operation of the braking and emergency lighting functions; hydraulic system filters must be kept away from the braking circuit to prevent failure caused by back pressure.

1. Severe Weather Response: The wind warning standard is refined to "no operation allowed when wind force is Level 6 or above; load limited to 70% of the rated value when wind force is Level 5". In high-temperature weather (≥ 35℃), the equipment oil temperature must be tested every 4 hours, and the equipment must be shut down immediately for cooling if the temperature exceeds 65℃; operators must be rotated for rest every 2 hours.

2. Confined Space Operations: A mandatory "test before entry" process is introduced. Gas detectors certified to ISO 21940-11 must be used, the oxygen concentration must be between 19.5% and 23.5%, and a dual-redundancy ventilation system and emergency escape respirators must be provided.

3. Night and Cross Operations: The illumination intensity is increased to ≥ 200lux, and the equipment must be equipped with LED warning light strips. For cross operations, the "time isolation method" is adopted: the interval between crane operations and ground construction must be ≥ 15 minutes, and physical isolation barriers (height ≥ 1.8m) must be installed.

1. Periodic Inspection Checklist: Verify the emergency braking response time (≤ 0.5 seconds) daily; test the hook fatigue status weekly (conduct curved beam stress analysis in accordance with ISO 17440); complete the aging test of hydraulic system seals monthly; and conduct gearbox oil spectral analysis quarterly.

2. Maintenance Safety Red Lines: Before maintenance, the "Lockout-Tagout (LOTO)" procedure for energy isolation must be implemented, and a "under maintenance" label with a QR code (scannable to check maintenance personnel and progress) must be posted. Specialized G6.3 class dynamic balance spreaders must be used for component disassembly to prevent vibration damage.

3. Digital Maintenance Records: Establish an electronic health file for the equipment, connect the inspection data to the OSHA supervision platform, and automatically trigger a locking mechanism for equipment that is overdue for maintenance to prevent it from starting.

1. Equipment Fault Handling: In case of boom jamming or abnormal motor noise, immediately start the "step-by-step unloading" procedure (pause for 30 seconds after every 1-meter descent), fix the boom with special tools before cutting off the power supply, and forced reset is prohibited.

2. Rescue for Injured Personnel: For personnel trapped by crushing, hydraulic spreaders (pressure ≤ 70MPa) must be used to avoid secondary injuries; for fractures, medical splints compliant with EN 13135 must be used, and a 1cm buffer space must be reserved for swollen parts of the limbs.

3. Fire and Environmental Emergency Response: For electrical fires, carbon dioxide fire extinguishers should be used first (dry powder fire extinguishers are only for outdoor use). After extinguishing the fire, fire-fighting wastewater must be collected and tested for pH value (6-9) before discharge to prevent soil pollution.
