Occupational Safety Training for Operating Gas Systems

1. Overview of the Gas System

a. What is a Gas System?

The gas system is a system designed to transport, store, and use various types of gases, including natural gas, fuel gas, liquefied gases (such as propane and butane), or other gases like noble gases. The gas system usually consists of components such as storage tanks, pipelines, valves, safety devices, and controllers to ensure safety and efficiency during operation.

The applications of gas systems are diverse, ranging from supplying energy to households and businesses, industrial use, chemical, medical sectors, to scientific research and space applications.

Some main components of the gas system include:

• Storage Tanks: These are places where gas is stored under high pressure. Storage tanks are usually made of steel or light alloys and designed to withstand high pressure without leaking.
• Pipelines: Pipes that convey gas from the storage tanks to gas-using devices, such as gas stoves or ovens. They are typically made from pressure-resistant and heat-resistant materials like stainless steel or copper.
• Valves and Safety Devices: Valves are used to control gas flow and ensure system safety. Safety devices include pressure sensors, overpressure protection valves, and flame detectors.
• Controllers: Controllers and pressure regulators are used to control gas flow and maintain stable pressure within the system.

Most importantly, the operation and maintenance of the gas system must be carried out carefully to ensure the safety of people and surrounding property. Everyone must follow safety instructions and conduct regular inspections to ensure the gas system operates correctly and does not pose any risks.

b. Operating Principles of the Gas System

The gas system operates based on basic principles of pressure and gas flow. Below are some basic principles of the gas system operation:

• Pressure: In the gas system, gas is stored in storage tanks under high pressure. The pressure is created by gas compressed and loaded into the tank. When a valve is opened, the high pressure generates gas flow from the tank to gas-using devices.
• Gas Flow: Gas moves from high-pressure areas to low-pressure areas. When the valve is opened, the high pressure in the tank causes gas to flow out through the pipes to the devices.
• Pressure Control: The gas system needs devices to control pressure, such as valves, pressure regulators, and controllers, to ensure the system pressure remains stable and safe.
• Safety and Protection: The gas system must be equipped with safety devices such as overpressure protection valves, flame sensors, and emergency shut-off valves to prevent hazardous situations like gas leaks or explosions.
• Gas Usage: Gas from the system is used in devices like gas stoves, ovens, heaters, and other equipment. When the valve opens, gas flows through the pipelines to these devices to be burned or used for other purposes.

c. Industries that Commonly Work with Gas Systems

• Energy Industry: In the energy sector, gas systems are widely used to supply energy to households, businesses, and production facilities. Natural gas is often used as a clean and efficient energy source.
• Industrial Sector: Industrial enterprises use gas systems for various purposes, including production processes, processing, and operating machinery. Gas is used in processes like welding, cutting, heating, cooling, and chemical reactions.
• Chemical Industry: In the chemical sector, gas systems supply raw materials and energy for chemical production processes. Various gases are used in chemical reactions to produce final products.
• Medical Sector: In healthcare, medical gases like oxygen and nitrogen are commonly used in medical devices such as respiratory support systems, surgical machines, and patient care equipment.
• Food and Beverage Industry: In food and beverage, gas systems provide heat for cooking, processing, and preserving food. Gases like propane and butane are often used in devices such as ovens and stoves.
• Oil Drilling and Industrial Mining: In oil drilling and industrial extraction, gas systems supply energy to equipment and production processes at drilling sites and energy stations.

2. Overview of Occupational Safety Training for Gas System Operation

a. What is Occupational Safety Training?

• Occupational safety training for gas system operation consists of sessions that equip workers with awareness on preventing occupational accidents. Workers directly involved with gas systems belong to Group 3.
• This training helps workers identify and avoid hazards, reducing risks of occupational accidents during work.

b. Training Duration

Initial safety training duration:

• The total training time is at least 24 hours, including testing time.
• 8 hours of theoretical study on safety policies and labor hygiene laws
• 8 hours of theoretical study on basic knowledge of occupational safety and hygiene
• 4 hours of theoretical study on specialized training content
• 2 hours of practical training on specialized content
• 2 hours of theoretical examination at the end of the training course

The safety training center will schedule training sessions based on workers’ availability. Usually, there are 6 training sessions over 3 days, provided the company can arrange continuous study time.

Periodic safety training duration:

• Before the occupational safety card expires, workers who want to renew it must undergo periodic occupational safety training, with the periodic training duration at least 50% of the initial safety training duration.

Explanation: The total periodic occupational safety training time is at least 12 hours, including testing. Upon completing periodic training and passing the test, workers will be reissued or have their occupational safety cards extended.

c. Training Content

d. Occupational Safety Card

After completing the occupational safety training and passing the test, workers will be issued an occupational safety card (commonly called the occupational safety certificate for Group 3).

The Group 3 safety card clearly shows information such as: full name, date of birth, job and specific working environment. It also includes training duration, red stamp, and signature confirming training completion.

According to the 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 endorse the safety card for the Group 3 trained worker after the training course and passing the test from the occupational safety training unit.
• If the worker is freelance, seasonal, and does not have a labor contract, the training unit must sign, stamp, and endorse the safety card for the worker after training and passing the test.

3. Hazards for Workers When Operating Gas Systems

• Gas Leak: Gas leaks from the gas system can create a toxic and dangerous working environment. Gases such as natural gas, propane, and butane can explode or cause fire hazards if leaked and exposed to flames or sparks.
• Asphyxiation: Certain gases like carbon monoxide (CO) can cause the risk of asphyxiation if their concentration in the air exceeds safe limits. Asphyxiation can lead to serious health issues or even death.
• Fire and Explosion: Natural gas, propane, butane, and other gases can create explosive atmospheres if dispersed in the air and exposed to flames or sparks. Fires and explosions can cause severe injuries, property damage, and fatalities.
• Toxic Poisoning: Toxic gases such as sulfur dioxide (SO2) and ammonia (NH3) can pose poisoning risks when inhaled. Long-term exposure to these toxic gases can cause serious health problems and bodily harm.
• High Pressure: Gas systems often operate under high pressure. Handling gas cylinders or equipment under high pressure without proper technique can result in serious accidents or injuries.
• Lack of Safety Awareness: A lack of safety awareness when working with gas systems, including not following safety rules and not using appropriate protective equipment, can create serious accident risks.

4. Measures to Control Occupational Accidents When Operating Gas Systems
