Conclusion
The safe operation of wet‑spraying rigs is critical to both personnel safety and equipment integrity. By clearly defining prohibited operations, establishing rigorous operating procedures, and strengthening staff training and management, accidents can be effectively prevented. It is recommended to develop a comprehensive manual of operational prohibitions, enhance routine inspections and oversight, and institute an accountability system to ensure that all restrictions are strictly enforced. At the same time, emphasis should be placed on fostering safety awareness, enabling operators to voluntarily adhere to established procedures and thereby providing robust assurance for the safe and reliable operation of the equipment.
