Fertilizer production lines involve multiple processes such as crushing, fermentation, granulation, and drying.  The equipment operates at high speeds, the raw materials are diverse, and some processes involve high temperatures, high pressure, and flammable materials. Standardized operation and strict adherence to safety protocols are essential for ensuring the safety of operators and the stable operation of the production line, preventing accidents. This document outlines core safety precautions based on practical production line scenarios, providing practical guidance for industry professionals.

Operators must be fully prepared before starting work, establishing a solid safety foundation. They must undergo professional safety training and operational drills, mastering the performance, processes, and emergency procedures of the equipment they operate.  Unauthorized personnel are not permitted to operate the equipment. During operation, protective equipment such as safety helmets, protective gloves, dust masks, and non-slip shoes must be worn as required.  For high-temperature and corrosive processes, additional heat-resistant and corrosion-resistant protective equipment must be worn to prevent unsafe practices.
Safety control during equipment operation is paramount. Before starting the equipment, a comprehensive check of the equipment status is necessary to confirm that the circuits, pipelines, valves, and transmission parts are functioning correctly and that safety devices are intact before starting the equipment. During operation, it is strictly forbidden to touch moving parts, feed inlets, discharge outlets, and other dangerous areas.  Unauthorized dismantling or adjustment of equipment parameters is strictly prohibited.  If any abnormal noise, electrical leakage, or other abnormalities are detected, the equipment must be immediately shut down and the power supply disconnected. The relevant personnel must be notified for handling, and operation with faulty equipment is strictly prohibited.
On-site environment and material management are equally important. The fertilizer production line site must be kept clean, with clear passageways.  The stacking of debris and flammable or explosive materials is strictly prohibited. Firefighting facilities must be fully equipped and regularly inspected to ensure they are in good working order. Raw materials and finished products must be stored separately and properly, away from fire and power sources, to prevent chemical reactions caused by mixed storage. In high-temperature processes such as fermentation and drying, temperature and pressure must be strictly controlled to prevent overheating and leaks that could lead to safety accidents.
After completing the work, proper shutdown procedures must be followed, including shutting down the equipment, disconnecting the power, closing valves, and cleaning residual raw materials from the equipment.  Daily maintenance of the fertilizer production equipment should also be performed. Safety handover records should be completed, clearly outlining subsequent precautions. Safety is paramount; only by strictly adhering to operating procedures and maintaining every safety precaution can we prevent accidents and ensure the efficient, safe, and orderly operation of the fertilizer production line.
