How does carbonyl dichloride (phosgene) affect workers’ health?
Nov
Carbonyl dichloride (phosgene) is a toxic chemical commonly used in the chemical industries. This article will help you understand the dangerous effects of phosgene on worker health and effective protective measures when working in an environment where this chemical is used.
1. What is Carbonyl dichloride (phosgene)?
The chemical formula CCl2O represents a toxic organic compound known as phosgene. It is a colorless gas with a musty odor and is very toxic to humans. Phosgene is primarily used in the chemical industry to produce organic compounds such as isocyanates and polyurethanes.
The molecular structure of phosgene consists of one carbon (C) atom bonded to two chlorine (Cl) atoms and one oxygen (O) atom. This substance readily reacts with other organic compounds, creating new products in chemical synthesis processes. Although phosgene is widely used in industry, it is one of the most dangerous chemicals.

2. Where does Carbonyl dichloride (phosgene) originate from in the production process?
In the production process, phosgene is typically generated in chemical reactions between carbon monoxide (CO) and chlorine (Cl2). This process occurs at high temperatures and pressures, under tightly controlled conditions, and is commonly used in industrial chemical manufacturing plants. Phosgene is an important intermediate product in the manufacturing processes of compounds such as isocyanates, polyurethanes, and pesticides.
Additionally, phosgene can also be generated in some side reactions during the production of other chemicals or under abnormal conditions where carbon monoxide and chlorine are present. Production environments may include chemical plants where phosgene is used or produced in processing and chemical synthesis stages.
Although phosgene can be produced in a controlled manner in factories, in the event of an incident or leak during operation, phosgene can be released into the environment, posing a risk to worker health.
3. Industries that use Carbonyl dichloride (phosgene) in production
Phosgene is primarily used in the chemical industries, where it plays a crucial role in the synthesis of many types of organic compounds. One of the most common applications of phosgene is in the production of isocyanates, a key component in the manufacturing of polyurethanes. Polyurethanes are widely used in the manufacturing industry for insulation materials, paints, carpets, cushions, and many other products.
In addition, phosgene is also used in the production of other compounds such as pesticides, plastics, and other complex organic chemicals. It is also used in the synthesis of compounds like chloroform and carbamates. These products play an important role in the agricultural, pharmaceutical, and materials manufacturing industries.
Besides its direct applications in chemical production, phosgene may also be found in other related industries involving polymer technology, the pharmaceutical industry, or in chemical research processes.
4. How does Carbonyl dichloride (phosgene) affect workers?
When workers are exposed to phosgene, this chemical can cause serious health effects, especially to the respiratory system. Phosgene is a toxic substance that can easily enter the body through inhalation, causing irritation to the respiratory tract lining and leading to serious problems such as coughing, difficulty breathing, chest pain, and even respiratory failure. Inhaling phosgene can lead to chemical pneumonitis, a serious condition with symptoms like shortness of breath, productive cough, and wheezing.
Not only does it directly affect the respiratory system, but phosgene can also cause acute poisoning if a worker is exposed to high concentrations for a prolonged period. Individuals with long-term exposure may experience cardiovascular, neurological, and liver/kidney function problems. Furthermore, phosgene can cause permanent lung tissue damage, leading to reduced respiratory capacity or chronic lung failure.
5. Permissible safe concentration of Carbonyl dichloride (phosgene) for human exposure
To ensure worker safety, health and occupational safety organizations have established maximum concentration levels of phosgene that humans can be exposed to without harm. This concentration is determined based on studies and health assessments of individuals with long-term exposure to phosgene in industrial environments.
According to the standards of organizations such as OSHA (the U.S. Occupational Safety and Health Administration), the concentration of phosgene in the air should not exceed 0.1 ppm (parts per million) over a one-hour work period. For the maximum permissible concentration of phosgene over an 8-hour workday, OSHA’s standard recommends the concentration should not exceed 0.02 ppm. If the phosgene concentration exceeds these limits, the risk to worker health increases significantly, leading to respiratory problems and other serious effects.
Other countries also have their own standards for permissible phosgene concentrations in the air, but in general, all recommend minimizing exposure levels and require workers to use specialized protective equipment in high-risk environments.
On a basic level, when working in an industrial environment, it is important to comply with safety standards and limit exposure to Carbonyl dichloride. 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 Carbonyl dichloride (phosgene) on worker health
To minimize the effects of phosgene on worker health, protective measures must be strictly implemented in the workplace. One of the most important measures is to control and minimize the concentration of phosgene in the air. Factories using phosgene must ensure effective ventilation in work areas, using extraction and filtration systems to remove harmful substances before they disperse into the air. This system must be regularly inspected to ensure its operational effectiveness.
In addition to controlling the concentration of phosgene in the air, providing workers with adequate protective equipment is crucial. Workers must use respirators that can filter toxic gases, protective clothing, and safety glasses to avoid direct contact with phosgene. These measures help prevent phosgene from entering the body through the respiratory tract, skin, or eyes.
Training and raising awareness for workers about the risks associated with phosgene is also an indispensable factor. Workers need to clearly understand preventive measures and how to react in case of an incident or phosgene leak. Training programs on occupational safety and emergency situations should be conducted regularly to ensure everyone is prepared to respond to dangerous situations.
Furthermore, regular health monitoring for workers is an important part of health protection. Those who are regularly exposed to phosgene need their health monitored, especially issues related to the respiratory system, to detect early signs of poisoning or diseases that may arise from phosgene.
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.
