Organic fertilizer, as a crucial pillar of green agriculture, involves multiple stages in its production process, including raw material processing, fermentation and maturation, molding, storage, and transportation. Each stage carries potential safety hazards. Standardized operations and strengthened prevention and control measures are not only the bottom line for ensuring the safety of workers but also crucial for ensuring orderly production and product quality. Based on practical production experience, safety precautions in the organic fertilizer production process mainly focus on the following aspects.
Raw material safety is the primary prerequisite for production. Organic fertilizer raw materials are mostly livestock and poultry manure, straw, and kitchen waste, requiring strict screening and control. The use of prohibited raw materials such as fly ash, sludge, and household waste is strictly prohibited. Raw materials requiring assessment must pass safety testing before use. Before raw materials enter the warehouse, they must be tested for heavy metals, pesticide residues, and pathogens. Unqualified raw materials are strictly prohibited from entering the warehouse. They must also be stored separately and clearly labeled to prevent confusion and misuse, avoiding safety risks and product quality problems caused by raw material contamination.
The fermentation stage is a key area for safety control. Organic fertilizer fermentation often employs aerobic or anaerobic processes, which produce gases such as hydrogen sulfide, ammonia, and methane, posing a risk of poisoning and explosion. Fermentation workshops must be equipped with gas concentration alarms, maintain good ventilation, and regularly monitor gas levels. Operators must wear protective gear, and the use of open flames in the fermentation area is strictly prohibited. Simultaneously, fermentation temperature, pH levels, and other parameters must be monitored in real time to prevent temperature runaway from damaging equipment or causing accidents. For confined space operations, the principle of "ventilation first, testing second, and operation last" must be strictly followed.
Equipment and operational safety cannot be ignored. Crushers, mixers, granulators, and other equipment used in production require regular maintenance and the installation of safety guards to prevent mechanical injuries. Operators must be professionally trained, certified, and familiar with operating procedures; violations are strictly prohibited. Processing workshops must be equipped with dust collection and explosion-proof devices, and accumulated dust must be cleaned regularly to prevent dust explosion risks; electrical wiring must be inspected regularly to prevent fires caused by aging.
Warehousing, transportation, and emergency management must be implemented simultaneously. Finished organic fertilizer must be stored separately in dry, well-ventilated warehouses, with stacks not too high to prevent collapse. Qualified vehicles should be used during transportation to avoid leaks and environmental pollution. Enterprises must develop comprehensive emergency plans covering emergencies such as fires, poisoning, and leaks, equip themselves with emergency supplies, conduct regular drills to improve the emergency response capabilities of employees, and establish a hazard identification mechanism to promptly rectify all safety hazards.
Safety is paramount, and responsibility is of utmost importance. Organic fertilizer production enterprises must strengthen their safety defenses, improve management systems, enhance the safety awareness of all employees, and integrate safety control throughout the entire production process. Only in this way can a win-win situation of safe production and green development be achieved, providing a solid guarantee for high-quality agricultural development.
