Acryloyl chloride (C3H3ClO) is a toxic chemical commonly used in manufacturing plants. So, how does Acryloyl chloride affect the health of workers? This article will explore the potential risks and ways to protect the health of those working in environments containing this chemical.
1. What is Acryloyl chloride?
The chemical formula C3H3ClO represents an organic compound containing three main elements: carbon (C), hydrogen (H), and chlorine (Cl). This chemical is a colorless or slightly yellow liquid with a strong, characteristic odor. It belongs to the group of halogenated compounds, is volatile and flammable, and is primarily used in the chemical, textile, and plastics industries.
The formula C3H3ClO indicates that this compound has three carbon atoms, three hydrogen atoms, one chlorine atom, and one oxygen atom in its molecular structure.
In an industrial environment, this compound can readily react with other substances to create different chemical compounds, and it serves as an important raw material in the production of polymers, paints, and detergents. However, due to its volatile nature and ability to cause strong chemical reactions, this compound must be handled and stored carefully to avoid hazards to health and the environment.

2. Where does Acryloyl chloride originate from in the production process?
During the production process, this compound usually arises from chemical reactions that take place in industrial plants, especially in the processes of manufacturing plastics and polymers. One of the main sources is from the processing of compounds like acrylic acid or its precursors in chemical reactions with chlorinating agents.
When producing certain types of plastics or other polymers containing this compound, the chlorination process of substances like acrylic acid will create the final product, acryloyl chloride. Additionally, in plants that manufacture paints, detergents, and wood preservatives, the processing of these raw materials can also lead to the generation of acryloyl chloride.
This compound can also appear in other industrial processes when carbon-containing organic substances react with chlorinating agents. This process often occurs at high temperatures and in specially controlled environments, where this chemical can be created as a byproduct or a main product, depending on the production process.

3. Industries that use Acryloyl chloride in production
This compound is widely used in many different industries, especially in chemical and material production processes. One of the industries that uses acryloyl chloride the most is the plastics industry, particularly in the production of specialty polymers. Acryloyl chloride is one of the key raw materials for creating chemical compounds that can be transformed into polymers with various applications from construction to consumer goods manufacturing.
In addition, acryloyl chloride is also applied in the paint and coatings industry. It acts as an agent in the synthesis of binders, helping to create durable paint films that are resistant to external factors such as temperature and humidity. Especially in industrial and automotive paints, acryloyl chloride helps improve the durability and resilience of the product.
In the textile industry, this compound is used to produce anti-wrinkle agents and wrinkle-free fabrics. Acryloyl chloride also participates in the synthesis of special polymers, helping to create fabric fibers with better abrasion resistance and strength.
Furthermore, this compound is also used in the manufacturing of detergents and industrial cleaning products. Here, acryloyl chloride helps create components that can effectively break down grease and dirt, serving cleaning processes in industrial environments.
4. How does Acryloyl chloride affect workers?
This compound can cause serious health effects for workers upon direct or long-term contact during the work process. When inhaling the vapor of acryloyl chloride, workers may experience respiratory problems, such as coughing, shortness of breath, and symptoms of bronchitis. Skin contact can cause irritation or burns, especially without adequate protective measures.
In addition to effects on the respiratory system and skin, acryloyl chloride can also affect the nervous system. Workers may experience symptoms such as dizziness, headaches, nausea, and fatigue. Those working in environments with high levels of acryloyl chloride or without effective ventilation systems are at risk of poisoning or central nervous system problems.
Specifically, prolonged exposure or exposure in environments with high concentrations of acryloyl chloride can increase the risk of chronic diseases, such as pneumonia or problems related to the liver and kidneys. In some studies, this compound is also suggested to have adverse effects on the reproductive system and may be a cancer risk factor.
5. Permissible safe concentration of Acryloyl chloride for human exposure
The safe concentration of this compound for human exposure depends on the regulations and standards set by international health and occupational safety organizations, such as the World Health Organization (WHO) and the U.S. Occupational Safety and Health Administration (OSHA). Studies and safety standards show that the maximum concentration of acryloyl chloride in the workplace air must not exceed a certain level to ensure the health of workers.
Specifically, OSHA regulates that the concentration of acryloyl chloride in the air should not exceed 0.1 ppm (parts per million) for an 8-hour work shift. This is the maximum concentration to which a worker can be exposed throughout a workday without adverse health effects.

On a basic level, when working in an industrial environment, it is important to comply with safety standards and limit exposure to Acryloyl chloride. 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 health effects of Acryloyl chloride on workers
To minimize the health effects of this compound on workers, applying safety measures in the workplace is extremely important. One of the basic and effective measures is to use a specialized ventilation and exhaust system. This helps to reduce the accumulation of chemical vapors in the air, lowering the risk of workers inhaling toxic gases.
In addition, fully equipping workers with personal protective equipment is also an important measure. Types of respirators, protective gloves, specialized clothing, and safety goggles will help prevent direct contact with acryloyl chloride, protecting the skin and respiratory system from negative impacts. Workers need to be instructed on how to use and regularly check the condition of their protective equipment.
Besides personal protection, production facilities also need to implement measures to control the concentration of acryloyl chloride in the air. Regular measurement and monitoring of the chemical concentration help to detect in a timely manner if the level in the air exceeds the safe limit. These measures will ensure that workers are not exposed to high concentrations of this compound, minimizing the risk of poisoning or long-term health problems.
Training and raising awareness for workers is also a crucial factor. Workers need to be equipped with knowledge about the potential risks when working with acryloyl chloride, how to prevent them, and how to handle dangerous situations. Furthermore, companies need to create conditions for workers to participate in periodic occupational safety training courses.
Finally, controlling and minimizing the emission of acryloyl chloride into the environment also contributes to protecting the health of workers. Factories and production facilities need to apply effective measures for treating exhaust gases and chemicals, minimizing the potential for acryloyl chloride to be dispersed outside the work environment.
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 hazard levels to prevent occupational diseases for them.
