Allyl chloride (C3H5Cl) is an industrial chemical commonly found in manufacturing plants. However, long-term exposure to this chemical can cause many adverse effects on the health of workers. This article will analyze in detail the risks and preventive measures.
1. What is Allyl chloride?
Allyl chloride, with the chemical formula C3H5Cl, is an organic compound containing three main elements: carbon (C), hydrogen (H), and chlorine (Cl). The formula C3H5Cl indicates that each molecule of allyl chloride consists of three carbon atoms, five hydrogen atoms, and one chlorine atom. This compound belongs to the halogen group of organic compounds and is widely used in the chemical industry, especially in the production of plastics, pesticides, and resins.
The molecular structure of allyl chloride has an allyl group (-CH2-CH=CH2) bonded to a chlorine atom. This gives allyl chloride special properties, making it an important substance in chemical reactions such as the synthesis of polymers, pharmaceutical compounds, and other industrial products.
Allyl chloride is a colorless, volatile liquid with a pungent odor; it is flammable and corrosive. It can be produced from the reaction between propylene and chlorine, through a chlorination process. Although widely used, allyl chloride is also a compound that can be harmful to health, especially with long-term human exposure.

2. Where does Allyl chloride originate from in the production process?
During production, allyl chloride is usually created through the reaction between propylene and chlorine. This reaction takes place under high temperature and pressure conditions, where chlorine (Cl2) reacts with propylene (C3H6), leading to the formation of allyl chloride (C3H5Cl). This is one of the most common methods for producing allyl chloride in the chemical industry. In addition, in some other chemical processes, allyl chloride can also be created as a byproduct during the synthesis of other compounds, such as plastics or polymers.

3. Industries that use Allyl chloride in production
Allyl chloride is widely used in many industries, especially in the production of plastics and polymers. One of its common applications is in the production process of polyvinyl chloride (PVC), where allyl chloride acts as an important raw material for synthesizing compounds capable of forming polymers. In addition, this compound is also used in the industry of manufacturing plastics, synthetic resins, and special chemical products such as pesticides.
The pharmaceutical industry also uses allyl chloride in the production of organic compounds, especially the precursors necessary for drug synthesis. Allyl chloride also plays a role in the production of cleaning agents, anti-corrosion substances, as well as in the production of compounds used in the paint and printing ink industries. Some other industries such as food processing, rubber production, and chemical additives also use allyl chloride in their production processes.
4. How does Allyl chloride affect workers?
Long-term exposure to allyl chloride can cause serious health effects for workers. This compound is corrosive and volatile, so when its vapor is inhaled, workers may experience respiratory problems such as coughing, shortness of breath, or symptoms of respiratory tract irritation. In case of direct contact with the skin or eyes, allyl chloride can cause burning, dermatitis, or eye irritation, leading to red and watery eyes.
In addition, if workers are exposed to allyl chloride for a long time or at high concentrations, this compound can cause serious effects on the central nervous system, causing dizziness, headaches, nausea, and fatigue. Severe cases can lead to liver or kidney damage, especially when this compound is absorbed through the skin or respiratory tract.
5. Permissible safe concentration of Allyl chloride for human exposure
According to the National Technical Regulation QCVN 10:2015/BLĐTBXH on occupational exposure limits for chemical factors in the workplace air, the maximum permissible concentration of allyl chloride in the air is 0.5 mg/m³ averaged over 8 hours.
Adherence to this limit is very important to protect the health of workers and avoid adverse effects from exposure to allyl chloride.

On a basic level, when working in an industrial environment, it is important to comply with safety standards and limit exposure to Allyl 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 effects of Allyl chloride on worker health
To minimize the effects of allyl chloride on worker health, protective measures must be strictly implemented in work environments where this chemical is used. One of the most important measures is to ensure good ventilation in production areas, which helps to reduce the concentration of allyl chloride in the air and prevent the inhalation of its vapor. The use of local exhaust ventilation systems to extract smoke and toxic gases from high-risk areas is essential.
In addition, fully equipping workers with personal protective equipment also plays an important role in protecting their health. Equipment such as chemical-resistant respirators, gloves, safety goggles, and corrosion-resistant protective clothing should be used correctly and their quality regularly checked. This helps prevent direct contact with allyl chloride, protecting the skin and eyes from damage caused by the chemical.
Furthermore, training programs on occupational safety and incident response procedures are also very important. Workers need to be trained on how to identify the risks associated with allyl chloride, how to use protective equipment correctly, and how to handle a chemical leak incident. Conducting regular health check-ups is also a necessary measure to detect early signs of poisoning and to provide timely treatment.
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 workplace environmental monitoring in factories and enterprises, collecting and analyzing factors harmful to workers, and from there, adjusting to reduce the level of harm to prevent occupational diseases for them.
