How does Methane affect workers’ health?
Jan
Methane (CH4) is a flammable gas that can seriously affect the health of workers in manufacturing plants that use this chemical. This article will explore the health impacts of methane, from asphyxiation and explosions to long-term issues like respiratory diseases, and how to protect workers.
1. What is Methane?
Methane (CH4) is a simple hydrocarbon gas with the chemical formula CH4, consisting of one carbon atom bonded to four hydrogen atoms. It is the main component of natural gas and is present in many natural processes such as the decomposition of organic matter, the combustion of fuel, or the digestive process of ruminant animals.
Methane is a colorless, odorless, and tasteless gas. It is flammable and can form an explosive mixture when combined with air within a certain range. Under normal conditions, methane exists as a gas and can easily permeate the surrounding environment. Although not directly toxic when inhaled in low concentrations, methane can be dangerous at very high concentrations as it displaces oxygen in the air, leading to a risk of asphyxiation.
Because methane is a potent greenhouse gas that affects global climate change, the use and management of this gas in factories and industries related to chemical production and consumption are crucial to ensure safety and environmental protection.

2. Where does Methane originate from during the production process?
During the production process, methane gas can be generated from various sources, especially in processing and manufacturing plants that use organic raw materials or carbon-containing chemicals. One of the main sources is the decomposition of organic compounds, such as when organic waste or carbon-containing materials are processed, decomposed, or burned in an oxygen-deficient environment.
In addition, methane can also be produced from manufacturing processes in the oil and gas industry, particularly during the extraction, processing, and transportation of natural gas. Chemical manufacturing plants may also produce methane gas during the processing of compounds like methanol, acetic acid, and other chemical products involving reactions that generate this gas.
Activities such as the storage and treatment of solid waste or emissions from landfills also contribute to the amount of methane released into the atmosphere.
3. Industries that use Methane in production
In manufacturing, many industries use methane as an important raw material or in their processing and production operations. One of the most prominent industries is the oil and gas industry. During the extraction and processing of natural gas, methane is the main component, often separated and used in the production of energy, electricity, and other products such as methanol and liquefied gas.
Additionally, the chemical industry also uses methane in the production of many chemicals like methanol, acetic acid, and ammonia. These chemicals are important raw materials for producing plastics, pharmaceuticals, pesticides, and other industrial products. Methane is used as a source material to create carbon compounds in chemical reactions.
In the food processing industry, methane can be generated from production, processing, or from organic waste treatment systems. Although methane is not a primary raw material, it can still be present in certain production activities.
The coal mining and processing industries are also a source of methane, as this gas can be released from coal seams during mining and processing.
4. How does Methane affect workers?
When workers are exposed to methane gas in the workplace, it can directly affect their health, especially at high concentrations. One of the most dangerous effects of methane gas is its ability to cause oxygen deficiency in the air. As methane concentration increases, the amount of oxygen in the environment decreases, which can lead to asphyxiation, dizziness, headaches, and in severe cases, loss of consciousness or death if not addressed promptly.
Furthermore, methane gas can also have long-term effects on the health of workers if they are exposed in poorly ventilated environments or without appropriate protective measures. Inhaling methane gas over a long period can lead to respiratory problems, damage the nervous system, and reduce cognitive function and reaction times. Although methane is not directly toxic like other gases, the lack of oxygen in the work environment can have a serious impact on workers’ health.
When methane combines with other gases like carbon monoxide or volatile organic compounds, the risk of explosions and fires in the production environment also increases, endangering the safety of workers.
5. Permissible safe concentration of Methane for human exposure
The safe concentration of methane for human exposure is determined based on the standards and regulations of health and occupational safety organizations. According to the World Health Organization (WHO) and safety agencies like OSHA (the U.S. Occupational Safety and Health Administration), the concentration of methane in the air should not exceed 1,000 ppm (parts per million) over a long period, which is equivalent to 0.1% methane in the air. At this level, methane does not cause serious negative health effects with short-term exposure.
However, the concentration of methane can become dangerous when it reaches 5% (50,000 ppm) in the air, as it can then reduce the amount of oxygen and lead to a risk of asphyxiation. Furthermore, methane can form an explosive mixture when its concentration reaches 5% to 15% in the air.
On a basic level, if working in an industrial environment, it is important to comply with safety standards and limit exposure to Methane. Organizations like the Occupational Safety and Health Administration (OSHA) in the United States provide guidelines and safety principles to protect workers from the negative effects of chemical substances.
6. Measures to minimize the health effects of Methane on workers
To minimize the health effects of methane gas on workers, control and prevention measures are very important in the workplace. One of the main measures is to improve the ventilation system in production areas or where there is a risk of methane generation. An effective ventilation system helps to dilute methane gas in the air, ensuring that its concentration does not exceed safe levels, thereby minimizing the risk of oxygen deficiency and other hazardous effects.
In addition, the use of methane gas measurement and warning devices is also very important. These devices help to continuously monitor the methane concentration in the air and provide a warning when the gas level exceeds safe limits, helping workers to be aware and take protective measures in a timely manner. These sensors should be placed at strategic locations in the factory, especially in areas with a high risk of methane generation.
Besides environmental control measures, training and raising awareness for workers is also a crucial factor. Workers need to be equipped with knowledge about the risks of methane and how to recognize the signs of asphyxiation or other unusual symptoms when exposed to this gas. Furthermore, providing adequate personal protective equipment, such as gas masks, also plays an important role in protecting workers’ health.
Finally, regular maintenance and inspection of equipment and machinery in the production process is another important measure. This helps ensure that there are no methane gas leaks from piping systems or gas-containing equipment, minimizing the possibility of gas escaping into the environment and harming the health of workers.
Occupational safety training: Workers need to be trained and educated about the risks and safety measures when working with this type of chemical. This training should be provided periodically and regularly to ensure understanding and proper compliance with safety rules.
Periodically organize occupational environment monitoring in factories and enterprises, collecting and analyzing factors harmful to workers, thereby adjusting to reduce hazard levels to prevent occupational diseases for them.
