The intrinsic safety design of the equipment eliminates risks at the source. All rotating components are equipped with fully enclosed guards, which are made of 5mm thick steel plates and have mechanical interlock devices. When the guard is not fully closed, the equipment cannot be started; if the guard is opened during operation, the equipment will automatically shut down within 0.5 seconds. The emergency shutdown system I designed is triple redundant: the red mushroom-shaped button on the operation console, the emergency stop button on the remote control, and the pull wire switch at the rear of the equipment. In the Swedish safety certification tests, my equipment passed all safety items and obtained the highest safety level of CE certification.
The operator protection system is people-oriented. The driver's cabin is designed according to the ROPS/FOPS standards, capable of withstanding 13 tons of lateral impact and 5 tons of top impact. The seat adopts air suspension and vibration reduction, and is equipped with four-point safety belts. The air conditioning system can reduce the indoor temperature from 50°C to 25°C within 3 minutes. I specially designed a fatigue driving monitoring system, which analyzes the facial features of the operator through cameras and automatically reminds them to rest if they have been working continuously for more than 4 hours. During the construction in the UAE during the summer, this system reduced the risk of heat stroke by 100%.
The safety protection of the operation area prevents third-party injuries. I developed a 360-degree panoramic monitoring system, with 8 high-definition cameras covering the equipment area without any blind spots. The ultrasonic radar has a detection range of 10 meters, and any person entering the dangerous area will trigger an audible and visual alarm. During night operations, the LED working lights have a lighting range of 30×20 meters, ensuring full lighting of the operation area. In the construction on German urban roads, this system successfully avoided 17 potential accidents.
The dust control technology protects health. The inhalable dust generated by concrete cutting is a serious health hazard. I designed a three-level dust removal system: the first level is wet dust removal, which captures 85% of the dust, the second level is cyclone separation, which captures 90% of the remaining dust, and the third level is HEPA filter for final purification. The dust removal efficiency reaches 99.95%, and the emission concentration is below 1mg/m³. In the tunnel project in Norway, my equipment in a confined space operation always has a dust concentration below the OSHA standard.
The protection of high-temperature components prevents burns. The surface temperature of the engine exhaust pipe can reach 500°C. I designed a double-layer heat insulation cover, with the outer layer being stainless steel plate, the middle layer being 50mm thick ceramic fiber, and the inner layer being an aluminum foil reflective layer. The surface temperature is controlled below 55°C, meeting the contact safety standards. I also added heat insulation sleeves to the hydraulic oil pipes to prevent accidental contact with heat. At the construction site in Kuwait, this design prevented multiple potential burn accidents.
The safety training system ensures standardized operation. I provide customized training for each customer: 8 hours of theoretical teaching, 16 hours of simulation operation, and 8 hours of on-site assessment. The training materials are available in 23 languages, covering all aspects from basic operation to emergency handling. The assessment adopts a triple evaluation method of practical operation + theoretical test + emergency drill, and only when all three are qualified can the operation certificate be obtained. In the large infrastructure project in India, I trained 800 operators, with a 100% pass rate and zero accident rate.
The intelligent safety management system is my latest innovation. Through Internet of Things technology, I can monitor the safety status of every device globally in real time: whether the operation behavior is standardized, whether the safety devices are intact, and whether the operation environment is safe. The system will automatically generate safety reports and promptly issue warnings for potential hazards. In the smart construction project in Canada, this system reduced safety violations by 96% and reduced insurance costs by 70%. The emergency toolkit is standardly equipped on each device and includes fire extinguishers, first aid kits, leak handling materials, and emergency communication equipment. During the emergency reconstruction efforts following the earthquake in Chile, my emergency response plan enabled the team to safely evacuate in the midst of aftershocks, with no casualties.
Building a safety culture is a long-term project. I helped clients establish a four-level safety culture: compliance level (adhering to regulations), participation level (active involvement), self-management level (self-regulation), and continuous improvement level (optimizing the system). In the five-year project in the United Arab Emirates, my client's safety culture score increased from 58 points to 94 points, and the cost of work-related injuries decreased by 88%.
True safety is not about increasing costs; it is about creating value through scientific design. The investment in safety protection on my diesel cutting machine has resulted in higher equipment availability, lower insurance costs, and better corporate reputation. These intangible values often exceed tangible costs, which is the fundamental reason why I always prioritize safety.
