b. Training Duration

Initial safety training duration:

• Total training time is at least 24 hours, including examination time.
• 8 hours of theory on policies, laws, and occupational safety regulations
• 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 theoretical assessment

The safety training center will divide the time into multiple sessions depending on workers’ schedules. Typically, there are 6 sessions over 3 days, provided the company can arrange consecutive training hours.

Periodic safety training duration:

• Before the occupational safety card expires, workers must undergo periodic safety training, with the periodic training time being at least 50% of the initial training time.

Explanation: The total duration of periodic safety training is at least 12 hours, including examination time. After completing the periodic training and passing the assessment, workers will be reissued an extended occupational safety card.

d. Occupational Safety Card

After completing the occupational safety training and passing the assessment, workers will be issued an Occupational Safety Card (commonly referred to as the Group 3 Safety Certificate).

The Group 3 safety card shows details such as name, date of birth, job, and working environment, as well as training duration, red stamp, and signature confirming completion.

According to regulations on card issuance stated 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 sign, stamp, and countersign the safety card for the Group 3 worker after completing training from an occupational safety training unit and passing the assessment.
• If the worker is freelance or seasonal, without a labor contract, the training unit must sign, stamp, and countersign the safety card after completing the training and passing the assessment.

3. Hazards When Operating a Boiler

Operating a boiler can involve many hazards if not performed correctly or without regular maintenance. Below are some common hazards when operating a boiler:

• Explosion or Fire: Boilers operate at high temperatures and pressures, and if temperature and pressure are not controlled, an explosion or fire may occur. This can cause serious injuries and property damage.
• Water Shortage: Lack of water in the boiler can lead to overheating, causing disruption in the boiler’s operation. This may result in fire or explosion.
• Uncontrolled Steam Release: When steam flows uncontrollably through the piping system, it can cause accidents and injuries to workers and potentially start a fire.
• Loss of Pressure Control: Loss of pressure control in the boiler can lead to an explosion or fire. Safety systems, pressure protection devices, and safety valves should be regularly inspected to ensure safety.
• Overtemperature and Overpressure: Excessive temperature or pressure can cause serious malfunctions. Temperature and pressure control systems must function correctly and be regularly checked.
• Operational Failures: Working with a boiler requires specialized knowledge and technical skills. Operational failures can pose safety risks and lead to fires.
• Toxic Gases: During fuel combustion, boilers can produce toxic gases such as CO (carbon monoxide) and NOx (nitrogen oxides). These gases can harm workers’ health if not properly controlled and removed.
• Water and Steam Leaks: Leaks of water or steam from the boiler can cause slips, hazards, and fire. Systems should be regularly inspected to prevent leaks.
• Power Outages: Power loss can stop boiler operation, leading to loss of pressure and temperature control, increasing risks.

To ensure safety when operating a boiler, strict safety rules must be followed, staff must be trained to work with boilers, and regular maintenance must be performed. Reviewing regulations and safety requirements is also a crucial step in minimizing risks.
