How does Carbon Disulfide affect workers’ health?
Mar
Carbon disulfide (CS2) is a hazardous chemical commonly used in manufacturing plants. This article will help you understand the impact of CS2 on workers’ health, from short-term to long-term risks, and how to protect yourself to minimize risks when working in an environment with this chemical.
1. What is Carbon disulfide?
Carbon disulfide (CS₂), also known as carbon disulfide, is an inorganic chemical compound with the molecular formula CS₂, consisting of one carbon atom bonded to two sulfur atoms. Under normal conditions, CS₂ is a colorless, volatile liquid with a characteristic odor similar to garlic or a pungent smell.
The CS₂ molecule has a linear structure with a –S=C=S functional group in the middle, similar to the structure of CO₂. The bond between carbon and sulfur in CS₂ is a nonpolar covalent bond due to the very small difference in electronegativity between carbon and sulfur.
CS₂ is widely used in many industries, especially in the production of artificial fibers such as rayon and cellulose. In addition, it is used as a solvent in chemical reactions and in the synthesis of sulfur-containing organic compounds.
However, CS₂ is flammable and can be harmful to health with long-term exposure, particularly affecting the nervous and respiratory systems. Therefore, the use and handling of CS₂ require strict adherence to safety regulations.

2. Where does Carbon disulfide originate from in the production process?
In the production process, CS₂ often arises from industrial processes related to the processing of sulfur-containing products. One of the main sources of CS₂ is the production of artificial fibers like rayon, where CS₂ is used to dissolve cellulose. This chemical can also be generated in the rubber, pharmaceutical, or other organic chemical manufacturing industries.
Additionally, CS₂ is created when sulfur-containing compounds, such as metal sulfides or other inorganic compounds, react with carbon under high-temperature conditions. This process primarily occurs in chemical plants where carbon is reacted with sulfur-containing compounds to produce CS₂.
In manufacturing plants that use CS₂, this substance can be generated from chemical reactions in processing equipment, furnaces, or from the use of solvents in production. These sources can cause air pollution if not properly controlled and treated.
3. Industries that use Carbon disulfide in production
CS₂ is used in many different industries, especially in the manufacturing of artificial fibers. In the textile industry, CS₂ is a key component in the production of rayon, an artificial silk fiber made from cellulose. This is one of the most common applications of CS₂, where it helps dissolve cellulose to create the fiber.
Besides the textile industry, CS₂ is also used in the rubber industry, particularly in the production of synthetic rubber. This chemical is used to create chemical reactions in the production of sulfur compounds, which helps improve the mechanical properties and durability of rubber.
The chemical industries also use CS₂ in the synthesis of sulfur-containing organic compounds. It can be used as a solvent in chemical reactions to produce products such as pesticides, herbicides, or other sulfur-containing compounds. In addition, CS₂ is also used in the pharmaceutical industry and in some special chemical processing procedures.
Due to its special chemical properties, CS₂ is also used in some other industries such as the production of paints, printing inks, and cosmetic products. Despite its widespread application, the use of CS₂ requires control measures and environmental protection, as this substance can be harmful if not handled properly.
4. How does Carbon disulfide affect workers?
Long-term exposure to CS₂ can cause many serious health effects for workers. One of the first effects is damage to the nervous system, including symptoms such as headaches, dizziness, nausea, and fatigue. People exposed to CS₂ may experience memory problems, reduced concentration, and difficulty performing tasks that require precision.
Besides the nervous system, CS₂ also affects the respiratory system. Inhaling CS₂ vapor can cause respiratory irritation, leading to coughing, shortness of breath, and a feeling of tightness in the chest. In cases of severe exposure, workers may suffer from serious conditions such as pneumonia or respiratory failure.
Furthermore, CS₂ can also have a negative impact on the cardiovascular system. Studies have shown that long-term exposure to CS₂ can increase the risk of cardiovascular diseases, such as hypertension or heart rhythm problems. In particular, for workers exposed to high and continuous concentrations of CS₂, the risk of these diseases can increase significantly.
Another effect of CS₂ is damage to the reproductive system, especially for men. Studies have shown that long-term exposure to CS₂ can reduce sperm quality and cause reproductive problems. This can affect the worker’s ability to have children later on.
The effects of CS₂ not only directly impact the health of workers but also reduce their quality of life and increase medical treatment costs for workers in industries that use this chemical.
5. Permissible safe concentration of Carbon disulfide for human exposure
In Vietnam, the permissible safe concentration of carbon disulfide (CS₂) in the workplace air is regulated in the National Technical Regulation QCVN 03:2019/BYT. This regulation specifies the permissible exposure limit values for 50 chemical factors, including CS₂.
On a basic level, if working in an industrial environment, adhering to safety standards and limiting exposure to Carbon disulfide is important. Organizations like 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 Carbon disulfide on workers’ health
To minimize the impact of CS₂ on workers’ health, applying personal protective measures and improving working conditions are very important. One of the first measures is to ensure adequate ventilation in work areas where CS₂ is used. Installing a suitable ventilation system will help reduce the concentration of CS₂ in the air, thereby reducing the risk of inhaling CS₂ vapor.
In addition, workers must be fully equipped with personal protective equipment such as masks, gloves, safety glasses, and full-body protective clothing when working with CS₂. This equipment will help limit direct contact with the chemical, protecting the body from the adverse effects of CS₂.
Training and raising awareness for workers also play an important role in minimizing risks. Workers need to be trained on safe methods when handling CS₂, how to recognize signs of poisoning, and first aid measures in case of an incident. Periodic training and health checks for workers will help detect early signs of illness due to CS₂ exposure, allowing for timely intervention.
Furthermore, companies also need to regularly check and monitor the concentration of CS₂ in the air. This helps ensure that the CS₂ concentration is always at a safe level according to regulatory standards, preventing workers from having to work in an environment with pollution exceeding permissible limits.
Finally, replacing or gradually reducing the use of CS₂ in production with less toxic chemicals is also a long-term solution to protect workers’ health. This change can help reduce health risks effectively and sustainably.
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 adherence to safety rules.
Periodically organize occupational environment monitoring in factories and enterprises, collecting and analyzing factors harmful to workers, thereby adjusting to reduce the hazard level to prevent occupational diseases for them.
