In recent years, mechanical accidents have become increasingly common in various production and processing facilities across our city. Many of these incidents involve employees who directly operate or perform maintenance on machinery without first shutting it down. As a result, their limbs often get caught in the equipment, leading to severe injuries such as amputation or even loss of life. These tragic events not only cause physical harm but also leave lasting psychological scars on the affected individuals and their families.
To prevent such incidents from happening, the safety supervision department has issued reminders to all business owners and workers about the importance of mechanical safety. One of the key principles is "stop before operating." This means that any work involving machinery must be carried out only after the machine has been completely turned off and secured.
For example, a few years ago, Su Long, an employee at a quarry, entered the front jaw plate of a crusher without turning it off, intending to clear mud from the material outlet. Unfortunately, his head was caught in the pulley, resulting in a fatal injury. The investigation revealed that the quarry had failed to install proper warning signs near the high-risk crusher and that the protective devices were incomplete.
Based on this incident, the safety authorities emphasized that all moving parts of machinery should be properly guarded, and high-risk equipment like crushers must have clear warning signs. Additionally, companies are required to provide thorough safety training to their employees, ensuring they are fully aware of potential risks and how to prevent them.
Another case involved Pengmou, a team leader at an artificial leather factory, who was caught between two drums on a production line, with a gap of just 4.2 cm. His head was severely crushed, and he later died in the hospital. The investigation found that the company lacked visible safety warnings and had inadequate operational procedures. Moreover, the safety education provided to employees was insufficient, leading to poor awareness of potential dangers.
This case highlights the importance of not only having proper operation procedures but also ensuring that employees receive regular safety training, including during transfers or when returning to work.
When it comes to hand injuries caused by machinery, immediate first aid is crucial. If a hand or finger is severed, the wound should be cleaned and bandaged to stop bleeding, and the injured area should be immobilized. It is important not to submerge the severed limb in alcohol or other disinfectants, as this can damage the tissue. Instead, the limb should be placed in a sealed plastic bag, surrounded by ice, and taken to the hospital as quickly as possible.
Operators must also remain vigilant and avoid working while fatigued. Before starting any machinery, workers should be familiar with safety protocols, wear appropriate attire (with tight collars, cuffs, and hems), and ensure that all safety devices are in place. Once the machine is running, the operator must stay at their post and avoid distractions. Fatigue should never be ignored, and workers must not disable or bypass safety mechanisms to speed up the process.
After the machine is turned off, it should be cleaned and maintained promptly. Safety should always come first—never compromise it for convenience or efficiency.
