DNT! Do you know what DNT and the principle of not interfering with safety mean?

In many of the Fortune 500 companies, there are descriptions of the DNT security principles, which are communicated to employees, visitors, and contractors as important security guidelines during training for new employees, as well as for visitors and contractors. This DNT safety principle is extremely important; whether they are employees, visitors, or contractors, they should never touch any dangerous machines, rotating parts, surfaces with high temperatures, electrical equipment, sharp edges, or objects with potential energy. Otherwise, serious work-related accidents may occur. Next, let’s take a look at what the DNT security principle is. Safety principle: Do not touch with your hands. 1. Do not touch sharp edges. Accident example: A new employee in the workshop saw that there were many raw materials piled up there. Out of curiosity, he wanted to know what material they were made of, so he touched them with his hands. Due to the sharp metal burrs on those materials, his blood vessels were severely cut. 2. Do not touch the rotating workpiece. Even cleaning iron shavings while the equipment is rotating. Accident case: Some experienced assembly workers* are used to touching the parts being tested with their hands to determine whether the bearings are overheating. A new worker in the workshop also imitated the methods of the experienced employees, which resulted in the tip of his finger being cut off by the rotating cutting mechanism. 3. Do not touch the cable; you don’t know if it’s electrically charged, so assume it is until a professional electrician verifies it. Accident case: A non-professional electrician used a knife to cut the cables in order to remove them from the sockets. Fortunately, touching the live cables caused an outage. 4. Avoid touching hot objects and components without caution; hot components must be clearly marked. Accident example: A workpiece that had just been welded was moved to another workstation, and due to the lack of any markings, another electrical technician’s arm came into contact with the workpiece, resulting in a burn. 5. Do not touch chemicals; their containers must be labeled, and never use beverage bottles to store chemicals. Accident case: A repairman put chemicals in the empty bottles of his favorite drinks and stored them in his toolbox. One day, while working, he felt thirsty, so he picked up the drink bottle and drank heartily. As a result, injury occurred, but thanks to emergency treatment, the life was ultimately saved. 6. Do not touch locked devices or those marked with lockout tags. Accident example: Unable to find a professional electrician, an employee went to the control room to get a key. The control box was turned on in an attempt to fix the electrical problems by oneself. As a result, they died from an electric shock. 7. Do not touch the cutting point. Accident example: A machine operator was *accustomed to using his fingers to check the surface roughness and quality of the workpieces. One day, his finger slipped into the cutting point, resulting in its amputation. 8. Do not touch the tight steel cables and compacted waste saw blades, as they contain a great deal of potential energy; if released, they can cause serious injuries. Accident case: A warehouse employee, while assisting with the shipping process, tried to pull apart twisted steel bars with his hands; the bars bounced back and injured the employee’s thigh, causing bleeding. 9. Do not touch objects that are about to fall. Accident example: A workshop worker instinctively reached out to hold back a steel plate that was about to fall; his weight was not sufficient to hold it in place, and the steel plate hit his abdomen, causing severe injuries. 10. Do not touch rotating objects while wearing gloves. Accident example: A lathe operator suffered a serious entanglement accident while grinding a rotating workpiece with polished surfaces, still wearing gloves.
