How does Carbon Oxysulfide affect workers’ health?
Mar
Carbon oxysulfide (COS) is a common chemical in manufacturing plants, but few people know about the dangerous harm it can cause to the health of workers. This article will help you better understand the effects of COS and how to protect your health when working in an environment where this chemical is present.
1. What is Carbon Oxysulfide?
Carbon oxysulfide, also known as carbonyl sulfide, is an inorganic compound with the chemical formula COS. It is a colorless, flammable gas with an unpleasant odor. The molecular structure of carbon oxysulfide consists of a carbonyl group (C=O) bonded to a sulfur atom (S) through a double bond.
This compound can be considered an intermediate between carbon dioxide (CO₂) and carbon disulfide (CS₂), both of which are isoelectronic with it. Carbon oxysulfide decomposes in the presence of moisture and bases into carbon dioxide and hydrogen sulfide. This compound is used as a catalyst in the formation of peptides from amino acids.

2. Where does Carbon Oxysulfide originate from in the production process?
During the production process, carbon oxysulfide is primarily generated from activities related to the production and use of sulfur, as well as chemical reactions involving carbon compounds. One of the main sources of COS is when manufacturing plants use CO2 or CS2 (carbon disulfide) in their chemical processing procedures. When these compounds react with other substances in the production environment, especially in high-temperature or high-pressure systems, carbon oxysulfide can be created as a byproduct.
Additionally, carbon oxysulfide can also be generated in other industrial processes such as petroleum refining, natural gas processing, and in the production of agrochemicals. Side reactions of organic compounds containing sulfur, such as combustion or the decomposition of these compounds, can also produce COS. In chemical manufacturing plants, especially those that use sulfur or sulfur-containing compounds, the level of carbon oxysulfide generation is higher.
3. Industries that use Carbon Oxysulfide in production
Industries that use carbon oxysulfide in production are mainly related to the chemical and heavy industry sectors. One of the primary industries is chemical manufacturing, particularly in the production of sulfur-containing compounds or complex organic chemicals. Carbon oxysulfide is used as a catalyst or in chemical reactions to create products such as peptides and other organic compounds.
Besides that, the oil and gas industry also sees the presence of carbon oxysulfide. During the refining of crude oil and natural gas, sulfur compounds can react to form COS. This occurs in natural gas processing plants and oil refineries, where the treatment of sulfur compounds is an essential part.
The pesticide and fertilizer manufacturing industries may also use carbon oxysulfide in some production processes. This chemical participates in the necessary reactions to create products for the agrochemical sector. Furthermore, the food and pharmaceutical industries may also use COS in some specific applications, although its usage is not as high as in the chemical and energy industries.
4. How does Carbon Oxysulfide affect workers?
When workers are exposed to carbon oxysulfide in the workplace, they can face many health hazards. This compound can enter the body through the respiratory tract when workers inhale COS gas in the air. With long-term exposure or at high concentrations, carbon oxysulfide can cause respiratory problems, such as coughing, shortness of breath, pneumonia, or other lung diseases. This is particularly dangerous in chemical manufacturing plants or facilities that use a lot of sulfur, where the concentration of COS in the air can exceed safe levels.
In addition to its direct impact on the respiratory system, carbon oxysulfide can also affect the nervous system. Workers with long-term exposure may experience symptoms like headaches, dizziness, fatigue, or other neurological issues. Studies have shown that inhaling COS gas in the work environment can impair neurological function, affecting the concentration and alertness of workers.
The impact of carbon oxysulfide also depends on the concentration and duration of exposure. If the concentration of COS in the air exceeds the permissible limit, the risk of harm to workers’ health increases, especially when there are no appropriate protective measures. Exposure to this gas not only causes immediate harm but can also lead to chronic health problems in the long run.
5. Permissible safe concentration of Carbon Oxysulfide for human exposure
In Vietnam, regulations on the concentration of carbon oxysulfide (COS) in the work environment are established to protect the health of workers. Although specific standards may change over time and by regulatory agency, in general, the maximum permissible exposure limits are often determined based on scientific research and international standards.
Globally, many countries and organizations have established occupational exposure limits for COS. For example, the World Health Organization (WHO) recommends that the concentration of COS in the air should not exceed 0.5 parts per million (ppm) to ensure worker safety. In the United States, the Occupational Safety and Health Administration (OSHA) sets the maximum exposure limit for COS at 0.4 ppm over an 8-hour workday.
These limits are established based on studies of the health effects of COS, aiming to prevent problems related to the respiratory and nervous systems of workers. Compliance with these regulations is necessary to maintain a safe working environment and protect worker health.
At a basic level, when working in an industrial environment, it is important to adhere to safety standards and limit exposure to Carbon Oxysulfide. 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 effects of Carbon Oxysulfide on worker health
To minimize the health effects of carbon oxysulfide on workers, strict prevention and control measures must be applied in the work environment. One of the most important measures is to control the concentration of COS in the air to ensure it does not exceed the safe limit. Good ventilation systems and modern air filtration equipment can help remove COS from the air, minimizing workers’ exposure to this toxic gas.
In addition, the use of personal protective equipment is an indispensable method. Workers should be equipped with anti-toxic masks, safety glasses, and protective clothing to minimize direct contact with COS gas. This protective equipment is especially important in areas with high COS concentrations, such as chemical manufacturing plants or oil processing facilities.
Training and educating workers about the health risks associated with carbon oxysulfide and preventive measures also play a crucial role. Workers need to clearly understand the symptoms they may experience upon exposure to COS and know how to handle incidents when they occur. At the same time, managers need to regularly inspect and maintain equipment and fire protection systems to ensure the work environment is always safe.
Finally, regular health monitoring of workers is another important measure to detect early signs of COS’s effects on health. Periodic health check-ups will help in the early detection of diseases caused by exposure to this gas and allow for timely treatment.
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 workplace environment monitoring in factories and enterprises, collect and analyze factors harmful to workers, and then adjust to reduce the hazard level to prevent occupational diseases for them.
