Occupational safety training for operating silk screen printing machines

1. Overview of the Screen Printing Machine

a. What is a Screen Printing Machine?

A screen printing machine, also known as a mesh printing machine, is a device used in screen printing technology to create images, text, or designs on various surfaces such as fabric, paper, plastic, metal, or wood. It is a traditional printing method favored for its ability to produce high-quality and diverse prints.

Applications

• Fashion: Printing designs on t-shirts, clothing, and accessories.
• Advertising: Printing advertising boards, posters, and signs.
• Art: Creating artistic prints on fabric or paper.
• Packaging: Printing logos and information on product packaging.

Advantages

• High Quality: Capable of producing sharp and durable images.
• Durability: Ink adheres firmly and lasts long, especially on difficult surfaces.
• Flexibility: Can print on many different types of surfaces.

Disadvantages

• High Setup Cost: Initial investment for machines and materials can be expensive.
• Long Preparation Time: The preparation and cleaning process can take time.

The screen printing machine is a powerful and flexible tool in the printing industry, helping create high-quality and professional printed products.

b. Operating principle of the Screen Printing Machine

Preparing the Screen Frame

• Frame and Mesh: A wooden or metal frame stretched with a thin mesh (usually nylon or polyester). The mesh functions to keep ink from leaking into unwanted areas.
• Coating with Photosensitive Emulsion: On the mesh, a layer of photosensitive emulsion is evenly applied. This layer hardens when exposed to light, creating a mask for the ink.

Creating the Print Design

• Exposure to Light: The design or image to be printed is exposed onto the photosensitive emulsion on the mesh. Typically, the design is placed on a film or a high-resolution print.
• Washing: After the emulsion layer dries and hardens, unwanted areas are washed away with water or cleaning chemicals. The result is an image or design shown on the mesh through the unblocked areas.

Applying Ink

• Ink Preparation: Ink is prepared and poured onto the mesh surface. Ink can be water-based, oil-based, or special ink depending on the material and surface to be printed.
• Ink Squeegee: Using a roller or squeegee, the ink is pulled across the mesh. The squeegee moves the ink through the open areas of the mesh and pushes it onto the printing surface. Ink only passes through the open mesh areas, creating the image or design on the target surface.

Drying

• Ink Drying: After printing, the product must be dried so the ink adheres firmly to the surface. Drying can be done with heat dryers or other suitable methods depending on the ink type.

Cleaning

• Cleanup: After the printing process, the mesh and equipment need to be cleaned to remove excess ink and remaining emulsion. This helps preserve the equipment and prepare for the next print run.

c. Industries using the Screen Printing Machine

Fashion Industry

• T-shirts and Clothing Printing: Screen printing machines are used to print designs, patterns, and logos on t-shirts, clothing, and fashion accessories.
• Swimwear and Shoes Printing: Screen printing is also applied for swimwear, footwear, and other accessories.

Advertising and Marketing Industry

• Advertising Boards and Signs: Used to print advertising boards, signs, and direction boards. Screen printing allows sharp and durable images on materials like plastic, metal, and wood.
• Posters and Flyers: Printing high-resolution, colorful advertising posters and flyers.

Art Industry

• Art Prints: Many artists use screen printing machines to create unique and high-quality art prints on paper, fabric, and other surfaces.
• Special Edition Prints: Producing limited edition or special version prints for artworks.

Packaging and Label Industry

• Product Packaging: Used for printing information and designs on product packaging such as boxes, bags, and bottles.
• Labels: Printing product labels with brand information and usage instructions.

Industry and Manufacturing

• Printing Components and Equipment: Used to print on electronic components, industrial equipment, and products requiring technical information or logos.
• Furniture Manufacturing: Printing designs and patterns on furniture products such as panels, curtains, and carpets.

Education and Training

• Books and Magazines: Used in publishing to create high-quality prints for books and magazines.

Food and Beverage Industry

• Labels and Packaging: Printing labels and packaging for food and beverage products, ensuring clear and attractive information.

2. Overview of Occupational Safety Training for Operating Screen Printing Machines

a. What is Occupational Safety Training?

• Occupational safety training for operating screen printing machines consists of sessions that equip workers with awareness on how to prevent occupational accidents. Those who work directly with screen printing machines fall under group 3.
• This safety training course helps workers identify and avoid hazards, reducing the risk of workplace accidents during operations.

b. Training Duration

Initial Occupational Safety Training Duration

• Total training time is at least 24 hours, including examination time.
• 8 hours of theory on policies and laws related to occupational safety and hygiene.
• 8 hours of theory on basic occupational safety and hygiene knowledge.
• 4 hours of theory on specialized training content.
• 2 hours of practical training on specialized content.
• 2 hours of final theoretical examination.

The safety training center will arrange the schedule into several sessions depending on worker availability. Typically, there are 6 training sessions over 3 days, provided the manufacturing enterprise can arrange continuous learning time.

Periodic Occupational Safety Training Duration

• Before the occupational safety card expires, workers who want to renew it must complete a periodic occupational safety training course, with the periodic training duration being at least 50% of the initial training duration.

Explanation: The total time for periodic occupational safety training is at least 12 hours, including examination. Upon successful completion and passing the test, workers will be reissued or have their occupational safety card renewed.

c. Training Content

d. Occupational Safety Card

After completing the occupational safety training course and passing the test, workers will be issued an occupational safety card (commonly called the occupational safety certificate for group 3).

The group 3 safety card clearly shows information such as: full name, date of birth, job and specific work environment. It also includes training time, a red stamp, and a signature confirming completion of the training course.

According to the regulations on issuing safety cards stated in Clause 2 of Article 24 of Decree 44/2016/ND-CP, there are two cases:

• If the employer and employee have a labor contract with each other, then the employer must sign, stamp, and endorse the safety card for the trained group 3 employee after completing the training from the occupational safety training unit and passing the test.
• If the worker is freelance or temporary without a labor contract, the training unit must sign, stamp, and endorse the safety card after the worker completes the training and passes the test.

3. Hazards for workers when operating the screen printing machine (Screen Printing Machine)

Chemical Hazards

• Ink and Chemicals: Ink and cleaning chemicals often contain compounds that can irritate the skin, eyes, or respiratory system. Prolonged exposure may lead to serious health issues such as dermatitis, allergies, or respiratory problems.

Mechanical Hazards

• Cutting and Moving Parts: Moving parts of the machine such as rollers, squeegees, and mesh frames can cause injuries like cuts, impacts, or pinching.

High Temperature Hazards

• Ink Drying: During the drying process, the dryer equipment can reach high temperatures, posing risks of burns or fire/explosion.

Strong Light Hazards

• Exposure to Light: The screen printing pattern making process often uses strong light, especially UV light, which can harm eyes and skin.

Work Posture Hazards

• Poor Posture: Standing or sitting in uncomfortable positions for prolonged periods can cause musculoskeletal problems, back pain, and fatigue.

Noise Hazards

• High Noise Levels: Screen printing machines can generate loud noise, affecting hearing if uncontrolled.
