b. Training duration
Initial occupational safety training
- Total training duration is at least 24 hours, including testing time.
- 8 hours of theory on safety policies and labor hygiene laws
- 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 course
The training center will divide the time into multiple sessions depending on worker schedules. Typically, there are 6 sessions, and the course lasts 3 days, provided the manufacturing company arranges continuous study time.
Periodic occupational safety training
- Before the occupational safety card expires, workers who wish to renew it must undergo periodic occupational safety training, with training time being at least 50% of the initial training duration.
Explanation: total periodic occupational safety training time is at least 12 hours, including testing. After completing the course and passing the exam, workers will have their occupational safety card renewed.

d. Occupational safety card
After completing the occupational safety training and passing the exam, workers will be issued an occupational safety card (commonly called Group 3 occupational safety certificate).
The Group 3 card shows information such as name, date of birth, job, and specific work environment. It also includes training duration, red stamp, and signature confirming course completion.
According to 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 seal the safety card for Group 3 workers after completing training and passing the exam.
- If the worker is freelance or temporary, without a labor contract, the training unit must sign, stamp, and seal the safety card after completing training and passing the exam.

3. Identifying Hazards Affecting Workers During Computer Manufacturing
There are several hazards that can affect the health and safety of workers during computer manufacturing. Below are some hazards that need to be identified:
