Key considerations to ensure the safe operation of organic fertilizer equipment include the following:

1. Operator training and qualification: Ensure that equipment operators have the necessary training and skills, and understand the equipment operation manual and safety procedures. Provide adequate training to new employees to ensure that they understand the operating procedures, safety precautions, and emergency response measures.

2. Regular inspection and maintenance: Establish a regular inspection and maintenance plan, including lubrication, fastening bolts, wearing parts replacement and other items. Check all parts and safety devices of the equipment to ensure that they are working properly and in good condition.

3. Safety guard: Ensure that the safety guard on the equipment is in good condition and that the operator knows how to use these devices correctly. Including but not limited to safety brake, emergency stop button, safety fence, protective cover, etc.

4. Fire and explosion prevention measures: If the organic fertilizer equipment involves flammable and explosive materials, ensure that there is no open flame around the equipment, no smoking, and the equipment operation area is required to be well ventilated.

5. Emergency preparedness: The operation site of the organic fertilizer production line should be equipped with the necessary first aid equipment and fire equipment, and all operators know how to use it. Develop emergency plans, including incident handling procedures and emergency contact information, to respond to unexpected events.

6. Equipment load and operation restrictions: comply with the maximum load and operation restrictions of the equipment, do not overload the use of equipment, and avoid equipment failures and security risks caused by overuse.

7. Clean the environment around the equipment: keep the environment around the equipment clean and tidy to prevent debris accumulation and slip and other safety problems.
