Occupational Safety Training for Screen Protector Manufacturing

1. Overview of Screen Protectors

a. What is a Screen Protector?

A screen protector is a thin protective layer placed on the surface of electronic device screens such as mobile phones, tablets, and laptops. The main purpose of a screen protector is to shield the screen from scratches, dust, and to reduce the risk of breaking when the device is impacted or dropped.

b. Machinery for Screen Protector Production

1. Laminating Machine

The laminating machine is an important device in creating the protective layer for screen protectors, especially for tempered glass and hydrogel protectors.

• Function: Applies the protective film layer onto the surface of the screen protector to increase durability and scratch resistance.
• Features: Uses pressure and heat to firmly bond the material layers together.

2. CNC Cutting Machine

The CNC (Computer Numerical Control) cutting machine is programmed to cut materials with high precision.

• Function: Cuts screen protectors to the desired size and shape.
• Features: High accuracy, capable of cutting complex shapes, suitable for both small-scale and mass production.

3. UV Printing Machine

The UV printing machine uses ultraviolet technology to print images and patterns onto the surface of screen protectors.

• Function: Prints designs, logos, or decorative patterns on the protectors.
• Features: Ink dries quickly under UV light, producing sharp and durable images.

4. Vacuum Laminating Machine

Vacuum laminating machines are primarily used in the production process of tempered glass screen protectors.

• Function: Laminates the protector onto the screen in a vacuum environment to remove air bubbles and ensure strong adhesion.
• Features: Ensures the protector is bubble-free and firmly attached to the screen.

5. Hardness Testing Machine

Hardness testers are used to evaluate the hardness and scratch resistance of screen protectors, especially tempered glass.

• Function: Measures the hardness of the protector to ensure quality standards are met.
• Features: Often uses the Mohs scale to assess scratch resistance.

6. Thickness Gauge

Thickness gauges are used to check the thickness of the protectors after production, ensuring uniformity and compliance with standards.

• Function: Accurately measures the thickness of the protector.
• Features: Can measure very thin thicknesses, suitable for various types of protectors.

7. Transparency Tester

Transparency testers assess the optical quality of the protector, ensuring it does not reduce screen clarity.

• Function: Measures transparency and light transmission of the protector.
• Features: Ensures the protector does not affect the display quality of the screen.

c. Common Types of Screen Protectors

• Plastic (PET) Protectors
  • Features: Made from polyethylene terephthalate (PET), a common plastic used in screen protection products.
  • Advantages: Affordable, easy to apply, does not affect image quality.
  • Disadvantages: Offers less protection compared to other types, easily scratched and less durable.
• Tempered Glass Protectors
  • Features: Made from tempered glass, offering much better scratch and impact resistance than plastic protectors.
  • Advantages: High durability, smooth touch feel, better screen protection.
  • Disadvantages: Higher cost, thicker which may change the user experience.
• Hydrogel Protectors
  • Features: Made from a flexible and softer material compared to PET and tempered glass, often self-heals minor scratches.
  • Advantages: Comprehensive protection, especially good for curved screens.
  • Disadvantages: Expensive, difficult to apply precisely, less durable than tempered glass.
• Matte (Anti-Glare) Protectors
  • Features: Have a matte surface to reduce glare from light.
  • Advantages: Minimizes reflections and glare, suitable for users frequently using devices outdoors.
  • Disadvantages: May reduce image sharpness, touch feels less smooth than tempered glass.

2. Overview of Occupational Safety Training for Screen Protector Production

In this article, we focus on issues related to Group 3 because Group 3 directly participates in the production process and faces the highest occupational safety risks. For reference on other groups, see here.

a. What is Group 3 Occupational Safety Training?

• Group 3 occupational safety training consists of sessions that equip workers with awareness and methods to prevent workplace accidents.
• The training helps workers identify and avoid hazards, minimizing risks of workplace accidents during their work.

b. Training Duration

Initial safety training duration

• Total training time is at least 24 hours, including testing time.
• 8 hours of theory on policies and laws on occupational safety and hygiene
• 8 hours of theory on basic knowledge of occupational safety and hygiene
• 4 hours of theory on specialized training content
• 2 hours of practical training on specialized content
• 2 hours of theoretical testing at the end of the training course

The safety training center will schedule the training into multiple sessions depending on the worker’s availability. Usually, there are 6 sessions, the course lasts 3 days, provided the production company arranges continuous training time.

Periodic safety training duration

• Before the occupational safety card expires, workers who want to renew must undergo periodic occupational safety training, with training time being at least 50% of the initial training time.

Explanation: total periodic safety training time is at least 12 hours, including testing time. After completing the periodic training and passing the test, workers will be reissued or have their occupational safety card extended.

c. Training Content

See more training contents of the 6 groups

d. Occupational Safety Card

After completing the occupational safety training 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 name, date of birth, job, and specific working environment. It also includes training duration, a red stamp, and a signature confirming course completion.

According to the safety card issuance regulations 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, the employer must sign, stamp, and endorse the safety card for the trained Group 3 employee after completing the training and passing the test.
• If the worker is freelance or seasonal 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.
