How does Methanol affect workers’ health?
Nov
Methanol (CH3OH) is a common chemical in many manufacturing industries, but it poses a significant risk to the health of workers. This article will help you understand the effects of Methanol on the body and how to protect the health of workers in environments where this chemical is used.
1. What is Methanol?
The chemical formula CH3OH represents a simple organic compound, known as methanol. It is one of the basic types of alcohol, primarily produced from natural gas or during the production of formaldehyde. Its molecular structure consists of a methyl group (-CH3) bonded to a hydroxyl group (-OH), forming a clear, colorless, volatile liquid with a characteristic odor.
Methanol is widely used in many industries such as chemical manufacturing, pharmaceuticals, and fuel, and is also present in consumer products like solvents, cleaning agents, and beauty products. However, despite its many industrial applications, methanol is a hazardous chemical and can cause serious harm to human health if exposed to or absorbed over a long period.
The volatile nature and water solubility of methanol allow it to easily enter the body through the skin, respiratory tract, or digestive system. Therefore, a clear understanding of the nature and properties of CH3OH is crucial for applying safety measures in work environments where this chemical is used.

2. Where does Methanol originate from in the production process?
During production, methanol can be generated from various sources, especially in the chemical processing and manufacturing industries. One of the main sources is the production of formaldehyde. In this process, methanol is used as a raw material, and through chemical reactions, some of the methanol is decomposed or converted into other compounds, but methanol gas can also be released into the environment.
Additionally, methanol can also be produced during fuel manufacturing, particularly in the natural gas processing industry. When natural gas is processed or during chemical synthesis, a certain amount of methanol can be generated. Especially in biofuel plants, methanol is one of the chemicals used to process biodiesel, which also leads to methanol emissions during production.
Furthermore, methanol can also be generated in other industrial activities such as the production of paints, industrial solvents, or in cleaning and washing processes. In these environments, methanol can exist as a vapor or liquid.
3. Industries that use Methanol in production
This volatile liquid is widely used in many industries, primarily in the production of chemicals, fuels, and consumer products. In the chemical industry, methanol serves as a basic raw material for producing other compounds such as formaldehyde, acetic acid, and various types of plastics and resins. Chemical processing plants use methanol in synthesis, transformation, or conversion processes to create higher-value products.
In the fuel industry, methanol is used as a raw material for producing biodiesel, a type of biofuel that serves as an alternative to petroleum. It is also used in the production of engine fuel, especially in blended fuels, to improve performance and reduce emissions.
Besides the chemical and fuel industries, methanol is also present in the production of paints and other industrial solvents. It is used in cleaning and washing processes in factories, as well as in the manufacturing of household products like paints, adhesives, and detergents. In plastic product manufacturing plants, methanol may be used to formulate PVC compounds, polycarbonates, and other synthetic plastic materials.
Furthermore, in the pharmaceutical industry, methanol is also used in the production of drugs, disinfectants, and personal hygiene products.
4. How does Methanol affect workers?
When exposed to this chemical, workers can experience serious health effects, especially when working in an uncontrolled safety environment. If methanol vapor is inhaled or comes into direct contact with the skin, the body can absorb this substance into the circulatory system, causing poisoning symptoms.
In the initial stage, poisoning symptoms may include headache, dizziness, nausea, and fatigue. If exposure is prolonged or absorption levels are high, methanol can affect the central nervous system, causing visual disturbances, loss of concentration, and even coma. One of the most severe effects of methanol is that it can cause temporary or permanent blindness, as methanol is metabolized in the body into formaldehyde and formic acid, two substances that can damage the eyes and other organs.
Additionally, methanol also adversely affects the liver and kidneys, the organs responsible for processing toxins in the body. Long-term exposure to methanol can lead to liver and kidney failure, causing serious health problems that can be life-threatening if not treated promptly. Moreover, workers in environments with high methanol concentrations without adequate protection are prone to respiratory diseases such as bronchitis and lung damage.
5. Permissible safe concentration of Methanol for human exposure
To ensure the safety of workers when exposed to this substance, health organizations and occupational health management agencies have established regulations on the permissible safe concentration in the work environment. According to international standards, the concentration of methanol in the air must be strictly controlled to minimize the risk of poisoning and adverse health effects.
Specifically, the Occupational Safety and Health Administration (OSHA) in the United States stipulates that the concentration of methanol in the air should not exceed 200 parts per million (ppm) over an 8-hour workday. This means that during an 8-hour shift, the methanol concentration in the air must not be higher than this level to ensure the health of workers. Additionally, if the methanol concentration exceeds 200 ppm, workers must be provided with respiratory protection equipment and take measures to minimize exposure risk.
The World Health Organization (WHO) has also issued guidance on methanol concentrations in the workplace, recommending that this level should not exceed 50 ppm for longer working periods. This is to limit the absorption of methanol through the respiratory tract and prevent the risks of poisoning, effects on the nervous system, and other organs.
In addition to controlling methanol concentration in the air, safety measures such as providing ventilation systems, personal protective equipment, and training workers on the risks of methanol exposure are also important factors in minimizing risk. Only when the methanol concentration in the work environment is properly controlled can workers perform their jobs safely and effectively.
At a basic level, when working in an industrial environment, it is important to adhere to safety standards and limit exposure to Methanol. Organizations such as the Occupational Safety and Health Administration (OSHA) in the United States provide guidelines and safety principles to protect workers from the negative impacts of chemical substances.
6. Measures to minimize the impact of Methanol on workers’ health
To minimize the impact of this substance on workers’ health, implementing comprehensive protective measures in the work environment is crucial. First and foremost, factories and workshops must control the concentration of methanol in the air to ensure it does not exceed safe levels. Establishing an effective ventilation system is one of the key solutions to reduce the amount of methanol in the air, prevent the accumulation of toxic gas, and protect workers from inhaling methanol vapor over long periods.
In addition, the use of personal protective equipment such as respirators, gloves, and protective clothing is necessary to limit direct contact with methanol. Especially in environments with high methanol concentrations, workers must be fully equipped with respiratory protection devices to prevent the inhalation of methanol vapor, thereby minimizing the risk of poisoning or respiratory issues.
Besides personal protective measures, training and raising awareness among workers also play a crucial role in reducing health risks. Workers need to be trained on the dangers of working with methanol, how to recognize symptoms of poisoning, and how to respond promptly in case of an incident. They also need to understand the importance of adhering to safety regulations and using protective equipment correctly throughout their work.
Finally, companies need to conduct regular health check-ups for their employees. This not only helps in the early detection of signs of methanol poisoning but also allows doctors to monitor the health status of workers throughout their employment with this hazardous chemical. Applying these measures not only helps protect the health of workers but also enhances work efficiency and reduces costs related to treating illnesses.
Occupational safety training: Workers need to be trained and educated on 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, collect and analyze factors harmful to workers, and thereby adjust to reduce hazard levels to prevent occupational diseases for them.
