Ethylene imine (C₂H₅N) is a dangerous chemical commonly used in industrial production. This article will provide a detailed analysis of the serious health effects of ethylene imine on workers, from respiratory issues to cancer risks, and offer effective protective measures.
1. What is Ethylene imine?
The chemical formula C₂H₅N represents an organic compound belonging to the amine group, containing two carbon (C) atoms, five hydrogen (H) atoms, and one nitrogen (N) atom. This chemical is also known as ethylamine and is one of the most common primary amines in industry. Primarily produced through the reaction of ethanol and ammonia, ethylamine is volatile and readily soluble in water.
This substance has a characteristic odor and can react with many other compounds, making it widely applicable in the chemical industry, especially in the production of pesticides, pharmaceuticals, and other synthetic compounds. However, its volatile nature also makes ethylamine a potential environmental pollutant and harmful to health if not strictly controlled.

2. What are the sources of Ethylene imine during production?
During the production process, the compound C₂H₅N can arise from various sources, mainly related to chemical reactions in processing industries. It is created when ethanol or compounds containing a hydroxyl group (–OH) react with ammonia under appropriate temperature and pressure conditions. This process typically occurs in chemical manufacturing plants, especially those that process organic products such as pharmaceuticals, pesticides, and synthetic resins.
Additionally, ethylamine can also be formed during the production of other chemical products like amines, polymers, or in the synthesis of complex compounds. The generation of ethylamine in the production environment can be due to its release during gas treatment stages, leaks from equipment, or the decomposition of raw materials.

3. Industries that use Ethylene imine in production
Ethylene imine is widely used in many industries due to its chemical properties, particularly its ability to react with other compounds to synthesize useful products. One of the main industries that use this compound is the pesticide manufacturing sector. Ethylene imine is used in the synthesis of plant protection products, helping to increase efficiency in controlling insects and pests.
Furthermore, this compound is also present in the pharmaceutical industry, where it plays a role in the synthesis of complex organic compounds used as raw materials for drug manufacturing. In the chemical industry, ethylamine is also used to synthesize synthetic resins, plastics, as well as other chemicals for the production of fabrics, paints, and other consumer products. Besides, the rubber industry also uses ethylamine in polymerization reactions to create materials with special properties.
4. How does Ethylene imine affect workers?
When exposed to ethylamine, workers can experience many adverse health effects, especially without appropriate protective measures. This chemical is easily absorbed through the respiratory tract, skin, or digestive system, causing immediate or long-term health problems. If ethylamine gas is inhaled, workers may experience irritation symptoms such as difficulty breathing, coughing, headaches, dizziness, and nausea. In severe cases, long-term or high-level exposure can lead to chronic respiratory problems or lung damage.
In addition to acute effects, prolonged exposure to ethylamine can also lead to more serious health issues, including effects on the nervous system and kidneys. Studies show that continuous exposure to ethylamine can cause neurological disorders, fatigue, and even memory loss. Moreover, some studies also indicate that ethylamine may pose a cancer risk with long-term, high-level exposure.
Furthermore, ethylamine can also cause skin and eye irritation, leading to symptoms such as red eyes, burning sensations, and dermatitis.
5. Permissible safe concentration of Ethylene imine for human exposure
To ensure worker safety, health and occupational safety regulatory agencies have established safe concentration levels for exposure to ethylamine. This concentration is determined based on studies of the chemical’s harmfulness to human health, as well as factors related to its absorption and accumulation in the body.
According to the standards of the Occupational Safety and Health Administration (OSHA) and other international organizations, the concentration of ethylamine in the air should not exceed 10 parts per million (ppm) over an 8-hour workday. This is the maximum permissible concentration that does not cause significant adverse health effects for workers. However, studies show that continuous or higher concentration exposure can cause serious health problems.
In addition, environmental control measures such as good ventilation and personal protective equipment for workers are also crucial to minimize risks. Adherence to these safe concentration standards and maintenance of adequate protective measures will help limit the impact of ethylamine on workers’ health, while ensuring a safe and effective working environment.

On a basic level, if working in an industrial environment, it is important to adhere to safety standards and limit exposure to Ethylene imine. 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 mitigate the health effects of Ethylene imine on workers
To minimize the impact of ethylamine on workers’ health, applying protective measures is extremely necessary. One of the most important measures is to improve the ventilation system in work areas. Ensuring good air circulation in the factory will help reduce the concentration of ethylamine in the air, thereby limiting the workers’ inhalation of toxic gas. This is particularly important for production areas where there is a risk of this chemical being generated during processing or manufacturing.
In addition, providing adequate personal protective equipment such as respirators, gloves, and chemical-resistant clothing is also an essential factor. This equipment will help prevent ethylamine from coming into direct contact with the skin and eyes, protecting workers from acute effects like skin, eye, or respiratory irritation. Especially for workers who are employed long-term in environments with a high risk of exposure to ethylamine, the use of respiratory protective equipment is crucial to protect the lungs and respiratory system from the effects of this toxic chemical.
Furthermore, companies also need to regularly inspect and maintain safety equipment to ensure they are operating effectively. Toxic gas alarm systems and devices for measuring ethylamine concentration in the air should be installed to monitor the work environment and take timely intervention measures when necessary. Training workers on the risks associated with ethylamine and prevention methods is also an important measure, helping them to recognize warning signs and know how to handle emergencies.
Finally, implementing regular health check-up programs for workers also plays a vital role in the early detection of health problems that may be related to ethylamine exposure. These measures, when applied synchronously, will help minimize the risk of ethylamine’s impact on workers’ health, creating a safe and healthy working 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 adherence to safety rules.
Periodically conduct occupational environmental monitoring in factories and enterprises, collecting and analyzing harmful factors for workers, thereby adjusting to reduce hazard levels to prevent occupational diseases for them.
