Carbonyl dichloride (phosgene) is a toxic chemical commonly used in the chemical industries. This article will help you understand the dangerous effects that phosgene can have on the health of workers in environments where this chemical is used.

1. What is Carbonyl dichloride (phosgene)?

Carbonyl dichloride (phosgene), with the chemical formula CCl₂O, is a chemical compound belonging to the carbonyl group. Phosgene is a colorless gas with a pungent odor, often used in the chemical industry, especially in the production of plastics, pesticides, and other organic compounds.

Regarding its chemical structure, phosgene consists of a carbonyl molecule (C=O) combined with two chlorine (Cl) atoms. This characteristic makes phosgene a very reactive compound, especially when in contact with substances with high moisture content. Phosgene is one of the most dangerous toxic substances and can cause serious health effects if workers are exposed to it during production.

Phosgene was first discovered in the 19th century and quickly became an important raw material in industrial production. However, due to its toxic and volatile nature, controlling and limiting exposure to phosgene in production environments is extremely important to ensure worker safety.

2. Where does Carbonyl dichloride (phosgene) originate from in the production process?

During the production process, carbonyl dichloride (phosgene) is primarily generated from the reaction between carbon monoxide (CO) and chlorine (Cl₂) under high temperature and pressure conditions. This reaction is usually carried out in chemical plants specializing in the production of organic compounds, especially during the manufacturing of plastics, pesticides, and other chemicals such as isocyanates.

In addition, phosgene can also be generated during the decomposition of chlorine-containing compounds or materials related to phosgene in the production environment. When these substances are exposed to high temperatures or harsh conditions, they can create phosgene as a byproduct.


3. Industries that use Carbonyl dichloride (phosgene) in production

Carbonyl dichloride (phosgene) is widely used in many chemical industries, particularly in the production of plastics, pharmaceuticals, and pesticides. In the plastics industry, phosgene is an important raw material for creating polycarbonate and polyurethane compounds, two types of plastics used in the manufacturing of consumer and industrial products.

In addition, phosgene also plays a role in the pharmaceutical industry, where it is used to synthesize certain types of drugs and medical chemicals. Phosgene participates in reactions that create complex organic compounds, thereby helping to produce products with special properties that aid in the treatment of many medical conditions.

In the field of pesticides, phosgene is used to produce organophosphate compounds, which are substances that kill insects. These substances help protect crops but also pose a potential risk to the health of workers if not carefully controlled during production.

Besides, phosgene is also present in many other industries such as the production of organic substances, textiles, and in food processing, where it participates in chemical reactions necessary for the final product.


4. How does Carbonyl dichloride (phosgene) affect workers?

When exposed to carbonyl dichloride (phosgene), workers can experience serious health effects. Phosgene is a toxic gas that can cause damage to the respiratory system when inhaled, especially at high concentrations. After entering the body through the respiratory tract, phosgene can directly affect the lungs, causing pulmonary edema, pneumonia, and difficulty breathing. Symptoms of phosgene poisoning may not appear immediately, but can be delayed from a few hours to a few days after exposure, increasing its danger.

In addition, phosgene can also cause eye and skin irritation, leading to symptoms such as redness, swelling, and a burning sensation. With prolonged or high-level exposure, phosgene can cause serious damage to body tissues, especially the respiratory organs, leading to long-term lung function decline or even death. In addition to immediate effects, prolonged exposure to phosgene can lead to chronic health problems.


5. Permissible safe concentration of Carbonyl dichloride (phosgene) for human exposure

The permissible safe concentration for exposure to phosgene is determined by international health and occupational safety organizations. According to standards set by the U.S. Occupational Safety and Health Administration (OSHA) and similar agencies worldwide, the maximum concentration of phosgene that can be present in the air is 0.1 ppm (parts per million) over an 8-hour workday. This is the level to which workers can be exposed without experiencing immediate serious health effects.

However, this concentration level may vary depending on factors such as the duration of exposure and specific working conditions.

On a basic level, if working in an industrial environment, it is important to adhere to safety standards and limit exposure to Carbonyl chloride (phosgene). 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 health effects of Carbonyl dichloride (phosgene) on workers

To minimize the health effects of phosgene on workers, strict safety measures must be applied in the workplace. One of the most important measures is to control the concentration of phosgene in the air. The use of effective ventilation systems, especially local exhaust ventilation, helps to reduce the concentration of the toxic gas in the workspace, thereby minimizing the risk of exposure.

In addition, providing adequate personal protective equipment such as respirators, safety glasses, gloves, and protective clothing is essential. This equipment helps prevent phosgene from coming into direct contact with the worker’s body, protecting them from the negative effects of the toxic gas.

Training and safety instruction for employees is also an important measure to reduce risk. Workers need to be equipped with knowledge on how to recognize and handle emergency situations in the event of a phosgene leak, while also understanding preventive measures and how to use personal protective equipment effectively.

Finally, regular health check-ups for workers and conducting phosgene concentration tests in the work environment are crucial for the early detection of signs of poisoning and for timely intervention.

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, to collect and analyze factors harmful to workers, thereby adjusting to reduce the level of hazard to prevent occupational diseases for them.
