b. Training Duration
Initial Safety Training
- Total training time is at least 24 hours, including testing.
- 8 hours of theory on safety policies and occupational safety laws
- 8 hours of theory on basic occupational safety knowledge
- 4 hours of theory on specialized training content
- 2 hours of practical training on specialized content
- 2 hours of final theory test
Safety training centers schedule sessions according to worker availability, usually in 6 sessions over 3 days if continuous learning is possible.
Periodic Safety Training
- Before the occupational safety card expires, workers must attend periodic safety training, with a minimum duration of 50% of the initial training time.
Explanation: The total periodic training time is at least 12 hours, including testing. After completing the training and passing the test, workers will be reissued or extended their safety cards.

d. Occupational Safety Card
After completing occupational safety training and passing the test, workers will be issued a safety card (commonly called occupational safety certificate for Group 3).
The Group 3 safety card clearly displays: full name, date of birth, job, work environment, training duration, official seal, and signature confirming completion of the course.
According to the regulations 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 endorse the safety card for Group 3 trainees after completion of training and passing the test.
- If the worker is freelance or temporary, without a labor contract, the training unit must stamp and endorse the safety card after training completion and passing the test.

3. Hazards When Operating Powered Pallet Jacks
Operating powered pallet jacks can pose several hazards if safety rules are not followed and proper training is lacking. Below are some common hazards when operating powered pallet jacks:
- Physical Injuries: Powered pallet jacks are often used to lift and move heavy objects. Improper use or failure to follow safety rules can result in physical injuries such as collisions, crushing, or slips and falls.
- Product Loss or Damage: Inaccurate handling of the pallet jack can lead to product loss or damaged components, resulting in waste and asset loss.
- Falling Loads: Lifting heavy objects carries the risk of items falling if not secured or lifted correctly. This can cause injury to personnel or property damage.
- Overloading the Jack: Exceeding the weight capacity of the powered pallet jack can damage the equipment and create hazardous situations.
- Fire and Explosion: In industrial environments such as chemical plants, using pallet jacks improperly in hazardous areas may lead to fire or explosion if safety measures are ignored.
- Unsafe Conditions in Toxic Environments: In workplaces with toxic substances, pallet jacks must be designed to protect operators from harmful chemicals and gases.
- Loss of Control or Equipment Malfunction: If a powered pallet jack loses control or suffers a technical failure during operation, dangerous situations can arise.
To mitigate these risks, operators of powered pallet jacks must follow safety rules, perform regular maintenance on the equipment, and participate in safety training programs. This helps reduce the risk of accidents and ensures safe operation of the pallet jack.
4. Accident Prevention Measures When Operating Powered Pallet Jacks
To prevent accidents when operating powered pallet jacks, several key measures should be implemented. Below are important control measures:
- Occupational Safety Training: Ensure all operators and relevant personnel are trained in safe use of pallet jacks, including operation, safety checks, and proper handling procedures.
- Regular Inspections: Inspection of pallet jacks should be performed periodically to detect safety issues such as wear, mechanical faults, or malfunctions, reducing the risk of accidents.
- Proper Use: Ensure the pallet jack is used according to the manufacturer’s instructions and safety rules. Avoid misuse or unsafe applications.
- Safe Load Handling: Do not exceed the pallet jack’s lifting capacity. The weight of objects should be verified and within the jack’s rated capacity.
- Personal Protective Equipment (PPE): Operators should wear appropriate PPE such as safety glasses, gloves, and heat-resistant clothing depending on the working environment.
- Technical Supervision: Use monitoring systems to track the jack’s operational status and detect faults early.
- Safe Work Environment: Ensure the workplace is safe for pallet jack operation by removing obstacles and hazards.
- Even Load Distribution: When lifting objects, ensure the load is evenly distributed to prevent tipping.
- Warning Signs and Signals: Use warning signs, signals, and lights to alert others when pallet jacks are in operation.
- Safety Planning: Plan tasks before operation, including risk assessment and specific safety measures.
- Emergency Handling: Train operators to handle incidents or emergencies during pallet jack operation.
- Incident Reporting: Require operators to report any accidents, incidents, or equipment failures immediately.
