Occupational Safety Training for Tennis Ball Manufacturing

1. Overview of Tennis Balls

a. What is a Tennis Ball?

A tennis ball is a type of ball used in the sport of tennis. It is an essential item in the tennis game and is designed with special characteristics to comply with the rules and requirements of this sport.

Characteristics of Tennis Balls:

1. Size and Weight: A tennis ball has a diameter of about 6.7 cm and weighs between 56 to 59 grams.
2. Material: Tennis balls are made from natural rubber, covered on the outside with a layer of felt, usually yellow or green for easy visibility on the court.
3. Structure: Tennis balls have a spherical structure with a rubber layer containing gas inside. When the ball hits surfaces, the gas inside helps produce the required bounce.
4. Pressure: Tennis balls are pressurized with gas to achieve the necessary bounce and response.

Function in Tennis:

• Resistance: Tennis balls are designed to withstand strong impacts from rackets and court surfaces without breaking or deforming much.
• Bounce: The bounce of the ball helps create varied shots and plays during the match.

Tennis balls play an important role in determining the quality of the game and affect how shots are executed.

• Process: Balls are inflated at a certain pressure to ensure bounce performance and durability.

4. Felt Gluing Machine

• Function: Gluing the felt layer onto the inner rubber layer of the ball.
• Process: Felt layers are firmly glued to the ball’s surface using special adhesives or heat bonding techniques.

5. Quality Inspection Machine

• Function: Checking the bounce, size, weight, and other quality standards of the balls.
• Process: Balls are tested using measurement and inspection devices to ensure they meet specified standards.

6. Packaging Machine

• Function: Packaging tennis balls into bags or boxes.

b. Training Duration

Initial safety training duration

• Total training time is at least 24 hours, including examination time.
• 8 hours of theory on the system of policies and laws regarding 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 examination at the end of the training course

The safety training center will arrange the training time over multiple sessions depending on the work schedule of employees. Usually, there will be 6 training sessions over 3 days, provided the manufacturing enterprise can arrange continuous training time.

Periodic safety training duration

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

Explanation: The total periodic occupational safety training time is at least 12 hours, including examination time. After completing the periodic training and passing the test, workers will be re-issued or have their occupational safety card renewed.

c. Training Content

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

• If there is an employment contract between the employer and the employee, the employer must sign, stamp, and endorse the safety card for the Group 3 worker after the worker has completed training from a safety training unit and passed the test.
• If the worker is freelance, seasonal, or does not have an employment contract, the training unit must sign, stamp, and endorse the safety card for the worker after completing the training and passing the test.
