Occupational Safety Training for Gas Cylinder Production

1. Overview of Gas Cylinders

a. What is a Gas Cylinder?

• A gas cylinder is a device for storing and transporting liquefied gas. It is widely used to supply energy for household appliances such as gas stoves, ovens, heaters, and many other devices. Gas cylinders are made from high-quality steel or aluminum, capable of withstanding pressure and preventing gas leakage. Cylinders are equipped with valves, gas level gauges, and safety valves to minimize the risk of fire, explosion, and accidents during use. Proper use of gas cylinders is crucial to ensure safety and avoid potential hazards.
• Vietnam is currently one of the largest producers and consumers of gas cylinders in Southeast Asia. Most gas cylinder manufacturing enterprises in Vietnam are either foreign-invested companies or joint ventures between foreign and Vietnamese partners.
• Gas cylinder manufacturers in Vietnam mainly produce cylinders with capacities from 12kg to 50kg, primarily supplying the domestic market. In addition, some companies export gas cylinders to international markets.

b. Machinery for Gas Cylinder Production

The machinery used in gas cylinder production includes:

• Steel Rolling Machine: used to manufacture cylinder shells from steel sheets.
• Submerged Arc Welding (SAW) Machine: used to weld the seams of cylinder shells.
• Gas Filling Machine: used to fill gas into cylinders during production.
• Quality Inspection Machine: used to check the quality of gas cylinders after production to ensure safety and compliance.
• Valve Crimping Machine: used to attach valves to the cylinder shells.
• Gas Production Machine: used to produce gas types to fill into cylinders.
• Gas Measurement Machine: used to measure the amount of gas filled into cylinders before packaging.

These machines are often integrated into an automated production line to improve efficiency and reduce production errors.

c. Typical Gas Cylinder Manufacturers

Notable gas cylinder manufacturers in Vietnam include:

• Vietnam Oil and Gas Group (PV Gas): Owns multiple gas cylinder factories and also imports and distributes gas nationwide.
• Vietnam Medical Equipment Joint Stock Company (VINAMED): Manufactures and supplies medical gas cylinders for hospitals and clinics across the country.
• Petrolimex Gas Trading and Service Company (PGB): A subsidiary of Petrolimex Group, producing and distributing gas cylinders nationwide.
• Petrosetco Gas Company Limited (PGC): Produces and distributes gas cylinders, owned by Vietnam Oil and Gas Group.
• Hung Anh Mechanical Company Limited: Manufactures and supplies industrial gas cylinders to major domestic and international clients.
• Petrolimex Saigon Gas Company Limited (PGS): Produces and trades gas cylinders, headquartered in Ho Chi Minh City with branches nationwide.

These are some of the prominent gas cylinder manufacturers in Vietnam, but many other companies also operate in this sector.

2. Overview of Gas Cylinder Occupational Safety Training

In this article, we focus on Group 3 because Group 3 is directly involved in production and is exposed to the highest occupational safety risks. For information on other groups, see here.

a. What is Group 3 Occupational Safety Training?

• Group 3 occupational safety training equips workers with awareness and methods to prevent occupational accidents.
• The training course helps workers recognize and avoid hazards, reducing the risk of accidents during work.

b. Training Duration

Initial safety training:

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

Training centers may distribute sessions based on worker schedules, typically over 6 sessions in 3 days if continuous study is possible.

Periodic safety training:

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

Explanation: total periodic training time is at least 12 hours, including assessment. After completion and passing the test, workers will have their safety cards renewed.

c. Training Content

d. Occupational Safety Card

After completing the training and passing the assessment, workers will be issued a Group 3 occupational safety card (commonly referred to as a Group 3 occupational safety certificate).

The Group 3 card displays the worker’s name, date of birth, job, and work environment, along with training duration, red seal, and signature confirming course completion.

According to Article 24, Clause 2 of Decree 44/2016/ND-CP, there are two cases:

• If there is a labor contract between the employer and the worker, the employer must sign, stamp, and validate the card after the worker completes training and passes the test.
• If the worker is freelance or seasonal without a labor contract, the training unit must sign, stamp, and validate the card after the worker completes training and passes the test.

3. Identifying Hazards in Gas Cylinder Production

During the gas cylinder production process, there are several hazards that may occur, for example:

• Gas cylinders contain a flammable and explosive gas, so there is a risk of explosion if not handled properly. Causes of explosion risks may include production equipment, production processes, or improper usage.
• Gas ignites when exposed to fire or other heat sources. Gas cylinder production may pose a fire and explosion risk if gas escapes and comes into contact with a flame or heat source.
• Chemical products may be harmful to the health of production staff, such as metal powders, welding fumes, or chemicals used in the production process.
• Production machinery and equipment for gas cylinders may also pose dangers to workers, such as cutting machines, compressors, welding machines, etc.
• Gas cylinder users may also endanger themselves and others if they do not follow proper usage procedures or safety instructions.

4. Common Occupational Accidents in Gas Cylinder Production

Common occupational accidents during gas cylinder production include:

• Eye injuries: Production staff may be at risk when using chemical products or if materials are ejected during production.
• Burns or scalds: Gas in cylinders operates under high pressure and may cause burns or scalds if mishandled. Additionally, hot materials or production equipment can also cause burns.
• Collision injuries: Workers may experience accidents from collisions with production equipment, materials, or other objects during production.
• Poisoning or toxicity: Production staff may be at risk when exposed to toxic chemicals, metal dust, or harmful fumes.
• Explosion or fire injuries: Gas is highly flammable and explosive, posing serious risks if not handled properly.

5. Safety Measures for Participating in Gas Cylinder Production

To ensure safety during gas cylinder production, the following safety measures should be implemented:

• Ensure production equipment and technology are regularly maintained and inspected for safety and operational efficiency.
• Provide guidance and training for staff on occupational safety, including safety procedures and environmental protection regulations.
• Ensure compliance with occupational safety and environmental protection regulations throughout the production process.
• Use personal protective equipment properly, including helmets, safety goggles, protective clothing, gloves, safety shoes, and masks when handling hazardous materials or chemicals.
• Implement fire and explosion prevention measures and other emergency procedures in case of accidents.
• Ensure the safety of materials and finished products during production, including thorough quality checks before products are released to the market.
• Conduct regular workplace environmental monitoring in factories, collecting and analyzing harmful factors to adjust and reduce risks, thereby preventing occupational diseases.
