VI. Occupational safety and health for painting and surface finishing personnel

1. Job characteristics of painting and surface finishing

Painting and surface finishing of a refrigerator requires a high degree of meticulousness and technical skill to ensure the product is not only beautiful but also durable over time. First, the electrostatic painting process is performed to apply a protective layer to the refrigerator’s surface. Electrostatic painting not only helps protect against corrosion but also creates a beautiful finish. This process requires the craftsman to precisely control the temperature and pressure to ensure the paint adheres firmly and evenly.

Next, surface inspection is an important step to ensure the quality of the paint layer. After painting, the refrigerator’s surface needs to be carefully inspected to detect any defects such as cracks, peeling, or uneven color. The craftsman uses specialized tools and techniques to inspect, ensuring that the finished surface meets the highest standards. If any defects are found, they must be repaired immediately to ensure a perfect product when it reaches the consumer.

Surface finishing is not just about painting but also includes polishing and maintenance. These steps help to create a smooth, shiny, and durable surface. The meticulousness in every small detail helps the product not only look beautiful but also withstand the effects of the environment, ensuring a long service life. This job requires the craftsman to have skill and experience, as well as care and responsibility to deliver the best quality product.
