Occupational safety training for operating LPG liquefied gas cylinders

1. Overview of LPG Cylinders

a. What is an LPG Cylinder (Gas LPG)?

An LPG cylinder (Liquefied Petroleum Gas) is a container that holds petroleum-based gas in liquid form, called LPG, for use in applications such as cooking, heating, vehicle fuel, and various industrial uses. LPG typically consists of hydrocarbons like propane and butane.

LPG is extracted from crude oil and natural gas, then processed to remove impurities and filled into cylinders. Inside the cylinder at low temperature and pressure, LPG remains in liquid form. When the cylinder valve is opened and pressure decreases, the LPG changes from liquid to gas, ready for use in various devices and applications.

b. Operating Principle of an LPG Cylinder

The operating principle of an LPG (Liquefied Petroleum Gas) cylinder involves maintaining proper pressure and temperature to keep the LPG in liquid form inside the cylinder and allow its use when needed. Here is a basic overview:

• LPG Cylinder: LPG is stored in a specially designed cylinder that can withstand high pressure. The cylinder is usually made of steel and includes a control valve to regulate gas flow.
• Pressure and Temperature: LPG is kept under high pressure inside the cylinder, which keeps it in liquid form at normal room temperature. This means LPG remains liquid as long as pressure and temperature are maintained at sufficient levels.
• Using LPG: When LPG is needed, the user opens the cylinder valve, reducing the internal pressure. As the pressure drops, LPG begins to change from liquid to gas, which can then be used in various devices and applications.
• Safety Conditions: Maintaining safe pressure and temperature in the cylinder is crucial to prevent accidents and LPG leaks, which could lead to fire or explosion. Therefore, LPG cylinders are usually equipped with safety devices such as pressure sensors and safety valves to ensure safe operation.

c. Industries that Use LPG Cylinders

LPG cylinders are widely used across multiple industries due to their convenience and versatility. Key industries include:

• Food and Cooking Industry: LPG is used in restaurants, hotels, fast food outlets, and food production facilities for cooking and steaming. It is also used in ovens, baking, and other cooking equipment.
• Chemical Industry: LPG can serve as a raw material or fuel for chemical production processes, including thermal processes, heating, and melting furnaces.
• Manufacturing Industry: LPG is used for heat applications in metal processing, glass production, and other manufacturing processes.
• Oil and Gas Industry: LPG is often produced as a byproduct of oil and gas operations and can provide heat for processing in this sector.
• Agriculture: LPG is used for cooking and heating in farms, as well as for sterilization and drying processes.
• Mining and Extraction: LPG can provide heat for drilling, rock processing, and other extraction operations.
• Healthcare Industry: LPG is used in medical equipment such as sterilizers, drug preparation ovens, and other healthcare applications.
• Fisheries and Seafood Industry: LPG is used for melting ice, heating, and creating optimal conditions for packaging and preserving seafood products.

d. Occupational Safety Card

After completing safety training and passing the exam, workers will be issued an Occupational Safety Card (commonly called Group 3 Safety Certificate).

The Group 3 safety card displays personal information, job, working environment, training duration, and includes an official stamp and signature confirming training completion.

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

• If the worker has a labor contract with the employer, the employer must sign and stamp the safety card after the worker completes training and passes the exam.
• If the worker is freelance or seasonal without a labor contract, the training unit must sign and stamp the safety card after completion of training and passing the exam.

3. Hazards When Operating LPG Cylinders

Operating liquefied petroleum gas (LPG) cylinders requires caution and strict adherence to safety rules to prevent hazards. Below are some common hazards when handling LPG cylinders:

• Fire and Explosion: LPG is highly flammable and explosive. Any gas leak combined with a flame or heat source can cause a dangerous fire or explosion. This can occur if the cylinder is damaged or improperly used.
• Gas Leaks: Any LPG leakage from the cylinder, valve, or piping can create a hazardous environment. LPG can accumulate in poorly ventilated areas, and if it comes into contact with a flame or heat source, a fire or explosion may occur.
• Overpressure: If an LPG cylinder is over-pressurized due to high temperature or other malfunctions, it can explode, causing injuries and damage.
• LPG Loss: Loss of LPG not only wastes fuel but also poses environmental and health risks. Loss may occur due to leaks or incidents during transport and storage.
• Incidents During Cooking or LPG Use: When using LPG for cooking or heating, improper use of equipment or leaving equipment unattended can lead to fire, explosion, or carbon monoxide (CO) poisoning.
• Storage and Transport Incidents: LPG must be transported and stored according to safety regulations. Any collisions, impacts, or incidents during these processes can cause leaks and explosion risks.
• Poor Ventilation: Using LPG in a poorly ventilated space can result in gas accumulation, increasing the risk of fire, explosion, or poisoning.

To ensure safety when operating LPG cylinders, users must follow specific safety guidelines for each application and always inspect cylinders, valves, and piping to ensure there are no leaks or damages. Regular maintenance and using safety devices such as leak sensors and fire alarms are also essential.

4. Measures to Control Workplace Accidents When Operating LPG Cylinders

Controlling workplace accidents during LPG cylinder operation is crucial for ensuring the safety of workers and the surrounding environment. Here are important measures to prevent accidents when handling LPG cylinders:

• Training and Education: Ensure all personnel involved in LPG operations are trained on safety rules and emergency measures. Training should cover the use of safety equipment, leak detection, and emergency response procedures.
