d. Occupational Safety Card
After completing the occupational safety training course and passing the examination, workers will be issued an occupational safety card (commonly known as Group 3 safety certificate).
The Group 3 safety card clearly displays information such as full name, date of birth, specific job, and work environment. It also shows training duration, red stamp, and signature confirming course completion.
According to the card issuance regulations in Clause 2 of Article 24, Decree 44/2016/ND-CP, there are two cases:
- If the employer and worker have a labor contract, the employer must sign, stamp, and validate the occupational safety card for Group 3 trainees after completing the course and passing the test from the occupational safety training unit.
- If the worker is freelance or seasonal and does not have a labor contract, the training unit must sign, stamp, and validate the occupational safety card after the worker completes the course and passes the test.

3. Recognizing Hazards in Memory Card Manufacturing
Some potential hazards affecting workers’ health and safety during memory card manufacturing may include:
- Memory card manufacturing often involves the use of chemicals and fine powders during production. These dust and fine particles can remain suspended in the air and be inhaled into the lungs, causing respiratory issues, pneumonia, or prostate disease.
- Memory card manufacturing often requires machines to operate continuously for long periods, which can generate high temperatures and intense light. Workers may suffer skin and eye damage if they do not wear adequate protective equipment such as helmets, safety goggles, and protective clothing.
- The use of chemicals, toxic gases, and lubricants in memory card manufacturing may create fire and explosion risks. Workers need fire prevention and firefighting training, and safety measures should be implemented to minimize these risks.
- Accidents such as collisions, burns, cuts, or crushing may occur during memory card manufacturing if safety measures are not followed and protective equipment is not properly used.
4. Common Occupational Accidents in Memory Card Manufacturing
Common occupational accidents during memory card manufacturing may include:
- Electrical accidents: Production processes in memory card manufacturing use many electrical devices, from machinery to small tools like cutters and scissors. Therefore, the risk of electric shock or short circuits is very high.
- Material-related injuries: During production, parts of machinery and various materials are used to create memory cards. These may fly off and injure factory employees.
- Chemical hazards: Chemicals used to produce memory card components can be harmful to health if not handled properly.
- Machinery malfunctions: Parts of machinery may break or degrade during use. If not repaired or replaced promptly, they may cause accidents for workers.
- Failure to use protective equipment: To protect employees’ health, memory card manufacturing factories need to provide adequate protective equipment such as safety goggles, gloves, masks, etc. If not used properly, accidents may occur.
5. Safety Measures When Participating in Memory Card Manufacturing
To ensure worker safety during memory card manufacturing, the following safety measures should be implemented:
- Ensure hygiene in the factory: Use sanitation methods to keep the workplace clean, ensure worker safety, and prevent contamination.
- Ensure electrical safety: Conduct regular inspections, maintenance, and use electrical protection devices to ensure safety in environments with many electronic devices.
- Training and provision of protective equipment: Workers should be trained on production procedures, machine operation, and protective equipment such as helmets, safety goggles, gloves, and protective shoes to ensure safety during work.
- Use safety equipment: Use explosion-proof devices, fire alarm systems, sprinkler systems, and rescue safety systems to ensure safety in all situations.
- Control temperature and humidity: Control temperature and humidity to ensure optimal working conditions for workers and proper storage of electronic components, preventing accidents during production.
- Quality inspection: Check the quality of components, materials, and finished products to ensure product quality and prevent accidents due to defective products.
- Ensure transportation safety: Transport products according to proper procedures, using full protective measures to ensure the safety of transport personnel and avoid accidents during transport.
- Periodically conduct occupational environment monitoring in factories, collect and analyze harmful factors for workers, and adjust to reduce hazards to prevent occupational diseases.
