Carbon disulfide (CS2) is a common industrial chemical, but it also poses potential health risks to workers. This article will help you better understand the serious effects of long-term exposure to CS2 in the workplace, from initial symptoms to long-term risks.
1. What is Carbon disulfide?
Carbon disulfide (CS2) is a chemical compound with the molecular formula CS2, formed from one carbon atom bonded to two sulfur atoms. It is a colorless liquid with a garlic-like odor and is highly volatile. It is flammable and capable of dissolving many organic substances. CS2 is widely used in the fiber, rubber, and pesticide manufacturing industries, and many other chemical industries.
CS2 has a low boiling point, only about 46°C, so it evaporates easily into the air, forming a gas that can be toxic to human health when inhaled over a long period. This chemical readily reacts with many other compounds, especially those containing -OH or -NH2 groups, and is used in many industrial production processes, such as in the production of synthetic rubber, artificial fibers, and organic solvents.

2. Where does Carbon disulfide originate from in the production process?
In industrial production, CS2 mainly arises from chemical processes involving the treatment of sulfur and carbon-containing raw materials. One of the common sources is in the synthetic fiber manufacturing industry, especially rayon fiber. This process requires CS2 as an intermediate raw material in converting cellulose into fiber.
In addition, in the rubber industry, CS2 is also used in the production of synthetic rubber, where it plays an important role in creating the necessary chemical reactions. CS2 is also used in the production of pesticides, detergents, and other organic solvents, in which high-temperature or high-pressure processes can generate CS2.
Besides production processes, CS2 can also be generated from incomplete chemical reactions or when sulfur is burned in an oxygen-deficient environment, creating CS2 as a byproduct.

3. Industries that use Carbon disulfide in production
CS2 is widely used in many industries, especially in the fields of chemical and synthetic material production. One of the main industries using CS2 is the production of synthetic fibers, especially rayon. In the rayon production process, CS2 acts as a chemical intermediate that helps convert cellulose into fibers, thereby creating products such as fabrics, clothing, and other consumer goods.
The rubber industry is also a major field that uses CS2, especially in the production of synthetic rubber. CS2 helps create the necessary chemical reactions to produce types of rubber with special properties, which are used in many products from car tires to building materials.
In addition, CS2 is also used in the production of pesticides, detergents, organic solvents, and in other chemical industries. CS2 is also present in the production processes of dyes, textile dyeing chemicals, and chemical products for the leather, seafood, and plastics industries.
Chemical manufacturing plants, especially those with fiber, rubber, or pesticide production processes, often use CS2 in their manufacturing and production processes.
4. How does Carbon disulfide affect workers?
When exposed to CS2, workers can experience many negative health effects, especially when working in unsafe environments or with high concentrations of CS2. One of the first effects is on the nervous system, as CS2 is a substance that can enter the body through respiration or skin contact. Inhaling CS2 gas can cause symptoms such as dizziness, headache, nausea, and fatigue. In the long term, it can lead to serious neurological disorders such as memory loss, emotional disorders, or even a decline in neurological function.
Besides the nervous system, CS2 also seriously affects the cardiovascular system. Workers with long-term exposure to CS2 may suffer from high blood pressure, heart rhythm disorders, and other cardiovascular problems. In addition, CS2 can also damage the respiratory system, increasing the risk of lung diseases, including pneumonia and chronic diseases such as bronchitis.
Another impact that cannot be ignored is the potential harm to the reproductive system and liver. Research shows that workers with long-term exposure to CS2 may experience problems related to infertility or reduced fertility. Signs of liver damage can also appear, including prolonged fatigue, abdominal pain, and changes in liver function.
5. Permissible safe concentration of Carbon disulfide for human exposure
To protect the health of workers in environments where CS2 is used, regulatory agencies have established permissible safe concentration levels for this chemical in the air. According to the standards of many international organizations such as the World Health Organization (WHO) and occupational health and safety agencies, the concentration of CS2 in the air must not exceed a certain level to ensure worker safety.
Specifically, the U.S. Occupational Safety and Health Administration (OSHA) stipulates that the concentration of CS2 in the workplace air should not exceed 20 ppm (parts per million) for an 8-hour workday. Studies have shown that when the concentration of CS2 exceeds this level, the risk of harm to workers’ health increases, especially for the nervous, cardiovascular, and respiratory systems. For workers in industries using CS2, this limit must be strictly adhered to in order to minimize the risk of health damage.

On a basic level, when working in an industrial environment, it is important to comply with safety standards and limit exposure to Carbon disulfide. 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 effects of chemical substances.
6. Measures to minimize the effects of Carbon disulfide on worker health
To minimize the effects of CS2 on worker health, a series of preventive and protective measures must be applied in the workplace. One of the most important measures is to improve ventilation in production areas. Ensuring fresh and well-ventilated air helps minimize the accumulation of CS2 in the air, thereby reducing the risk of exposure for workers. Mechanical ventilation systems can be installed to extract toxic gases from the workspace and replace them with clean air.
In addition, the application of personal protective measures for workers is extremely necessary. Workers need to be fully equipped with personal protective equipment, especially types of gas masks or closed-circuit breathing apparatus to avoid inhaling CS2 during work. Furthermore, skin protection is also very important, as CS2 can penetrate the skin upon direct contact. Therefore, the use of gloves, protective clothing, and other protective equipment is necessary.
Companies need to regularly check and monitor the concentration of CS2 in the workplace air. This helps ensure that the CS2 concentration does not exceed the permissible safe level and allows for timely adjustments of control measures when necessary. Training and raising awareness for workers about the risks associated with CS2 also play an important role in preventing occupational accidents and diseases.
Finally, technical measures in the production process should also be considered to minimize the use of CS2. Replacing CS2 with safer chemicals or improving production processes to reduce the amount of CS2 used can be a long-term solution to protect worker health.
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 the level of risk to prevent occupational diseases for them.
