b. Training Duration
Initial safety training duration
- Total training duration is at least 24 hours, including test time.
- 8 hours of theoretical learning about the system of occupational safety and health policies and laws
- 8 hours of theoretical learning about basic occupational safety and health knowledge
- 4 hours of theoretical learning about specialized training content
- 2 hours of practical training on specialized training content
- 2 hours of theoretical test at the end of the training course
The safety training center will allocate time into multiple sessions depending on the scheduling for employees. Normally, there will be 6 sessions over 3 days, provided the manufacturing enterprise arranges continuous study time.
Periodic safety training duration
- Before the occupational safety card expires, workers who want to renew must undergo periodic occupational safety training, with training duration of at least 50% of the initial safety training duration.
Explanation: the total duration of periodic occupational safety training is at least 12 hours, including test time. After completing the periodic training and passing the test, the worker will be reissued or have their occupational safety card extended.

d. Occupational Safety Card
After completing occupational safety training and passing the test, the worker will be granted an occupational safety card (commonly known as a group 3 occupational safety certificate).
The group 3 safety card will clearly state information such as full name, date of birth, job, and specific working environment. It also includes training duration, red stamp, and signature confirming completion of the training.
According to the regulations on issuing safety cards specified 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 stamp and sign the safety card for Group 3 employees after they complete training from an occupational safety training unit and pass the test.
- If the worker is freelance or seasonal without a labor contract, the training unit must stamp and sign the safety card after the worker completes training and passes the test.

3. Identifying hazards affecting workers in tea manufacturing
Hazards affecting workers in tea manufacturing include:
- During tea manufacturing, machinery can generate thermal effects, electrical short circuits, high pressure, and flammable liquids. Therefore, it is necessary to ensure safety in the use of power sources and lighting, and to keep the workspace clean and ventilated to minimize the risk of fire and explosion.
- Workers directly exposed to tea must maintain personal hygiene and wash hands before performing tasks related to tea. Personal protective equipment such as masks, gloves, aprons, and safety shoes must be used to minimize the risk of infection or poisoning.
- Tea manufacturing machinery can cause accidents such as collisions, falling objects, cuts, crushing, entrapment, or being pierced by machine parts. Therefore, it is necessary to fully implement occupational safety measures such as using protective equipment, avoiding wearing jewelry while working, and preventing unskilled individuals from operating machines.
- During the manufacturing process, dust and chemicals may be released from machines or raw tea materials. Tea production workers must be provided with protective equipment to minimize exposure to dust and hazardous chemicals, as well as trained to handle chemicals safely and properly.
- If electrical equipment in the factory is not regularly maintained, insufficiently insulated, or not waterproof, it may pose an electrocution hazard to workers during manufacturing.
4. Common types of occupational accidents in tea manufacturing
Common types of occupational accidents that may occur during tea manufacturing include:
- Chemical poisoning: Chemicals used for pest control or tea preservation can cause poisoning if not used properly.
- Physical injuries: Due to the movement and handling of heavy loads, workers may suffer injuries from collisions or accidents if protective equipment is not properly used.
- Electrocution: Electrical machines and devices can endanger untrained workers or those not using proper protective equipment.
- Fire and explosion: The use of flammable substances or fuels for equipment operation exposes tea workers to fire and explosion risks.
- Unsafe working conditions: Working in environments with high humidity, insufficient lighting, or poor ventilation may also pose health risks to employees.
5. Safety measures in tea manufacturing
Ensuring worker safety during tea manufacturing is essential to prevent occupational accidents and protect employee health. Below are some safety measures to be implemented in tea production:
- Ensure food safety and hygiene: Tea is a consumable product, therefore processes related to tea processing must comply with food safety regulations. Employees must be trained to follow hygiene practices, including washing hands before work, using personal protective equipment, and keeping equipment and the workplace clean.
- Use personal protective equipment: The use of personal protective equipment such as helmets, masks, gloves, and safety glasses helps reduce risks of injury and allergic reactions caused by exposure to chemicals during production.
- Proper use of machinery: Workers must be trained to properly use machinery and necessary tools, ensuring safety for themselves and others.
- Ensure safety in transportation: Tea transportation must also be safe to prevent product damage and accidents during transit.
- Implement risk management: Tea factories must have risk management plans and response measures in case of accidents or incidents.
- Provide occupational safety training: Workers must be trained in occupational safety measures and made aware of risks associated with tea production.
- Conduct regular occupational environment monitoring in factories and enterprises, collecting and analyzing harmful factors for workers, thereby reducing risks to prevent occupational diseases.
