Benzenediamine (C6H8N2) is a hazardous chemical commonly used in manufacturing plants. This article will help you understand the impact of benzenediamine on the health of workers, from acute to chronic diseases, and how to protect your health in the work environment.
1. What is Benzenediamine?
Benzenediamine, with the chemical formula C6H8N2, is an organic compound belonging to the aromatic amine group. The structure of benzenediamine consists of a benzene ring (C6H5) with two amino groups (-NH2) attached at different positions on the ring. These amino groups have strong chemical reactivity, making benzenediamine an important raw material in many chemical industries.
This compound has two main isomers, depending on the position of the two amino groups on the benzene ring. If the amino groups are attached at opposite positions, it forms 1,3-benzenediamine, whereas if they are attached at adjacent positions, it forms 1,2-benzenediamine. This property makes benzenediamine a very versatile substance in chemical reactions and industrial applications.
With its characteristic chemical properties, benzenediamine is often used in the production of plastics, synthetic resins, rubber, dyes, and other organic compounds. This compound is also an important raw material in the synthesis of various drugs and detergents.

2. Where does Benzenediamine originate from in the production process?
This compound primarily arises during the production of chemicals and industrial materials. In the plastics, rubber, dye, and textile industries, benzenediamine is widely used as a basic raw material to create products such as polyurethane, synthetic rubber, and dyes.
In addition, during the production of these chemicals, benzenediamine can be generated as a byproduct from the reaction between benzene and aminating agents. The production of these compounds can create gas or dust containing benzenediamine, increasing the risk of exposure for workers in the production environment.

3. Industries that use Benzenediamine in production
Benzenediamine is used in many industries, especially in the production of plastics and rubber. In the plastics manufacturing industry, it is an important raw material in the production of various types of polyurethane, a versatile plastic with high applicability in many fields such as automotive, construction, and electronic devices. Benzenediamine is also involved in the production of heat-resistant plastics and composite materials.
In addition, this compound is also used in the dye and textile industries. Benzenediamine compounds help create colorfast dyes, especially in the synthetic fiber dyeing industry. Other applications of benzenediamine include the production of detergents, industrial additives, as well as in the synthesis of other organic compounds.
The rubber manufacturing industry is also a field that uses benzenediamine. In the production of synthetic rubber, especially heat-resistant rubber, benzenediamine plays an important role in improving the mechanical properties and durability of the material.
4. How does Benzenediamine affect workers?
When workers are exposed to benzenediamine, this substance can cause serious health effects. Benzenediamine is a toxic compound that can enter the body through the respiratory tract, skin, or through contact with products containing this chemical. When inhaling the dust or vapor of benzenediamine, workers may experience respiratory irritation symptoms such as coughing, shortness of breath, pneumonia, or asthma.
In addition, prolonged exposure to benzenediamine can also cause serious effects on the skin and eyes. If this substance comes into direct contact with the skin, it can cause skin irritation, contact dermatitis, or even severe skin damage if not treated promptly. When it gets into the eyes, benzenediamine can cause conjunctivitis, eye pain, and the risk of vision loss if left untreated.
Not only does it cause acute symptoms, but benzenediamine can also have long-term effects, especially on the liver and kidneys. Workers with long-term exposure to benzenediamine may experience liver problems such as hepatitis, cirrhosis, or issues related to kidney function. Furthermore, this substance can also cause diseases related to the reproductive system, and even cancer with long-term exposure and without appropriate protective measures.
5. Permissible safe concentration of Benzenediamine for human exposure
Currently, there are no specific regulations on the permissible safe concentration of benzenediamine in the work environment in Vietnam. However, health and occupational safety agencies recommend that to protect workers’ health, exposure to benzenediamine should be limited to the lowest possible level. Adhering to occupational safety measures, using personal protective equipment, and implementing control measures in the work environment are very important to minimize the risk of exposure to this substance.

On a basic level, when working in an industrial environment, it is important to comply with safety standards and limit exposure to Benzenediamine. 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 Benzenediamine on worker health
To minimize the effects of benzenediamine on worker health, it is extremely important to apply protective measures. One of the first measures is to control the concentration of benzenediamine in the workplace air, ensuring that the exposure level does not exceed the permissible safety limits. Using an effective ventilation system in production areas containing benzenediamine helps to reduce the concentration of this substance in the air, thereby reducing the risk of inhaling harmful dust particles or vapors.
In addition, workers need to be fully equipped with personal protective equipment, including chemical-resistant respirators, protective gloves, and safety glasses, to limit direct contact with benzenediamine. Especially in high-risk work environments, the use of specialized protective gear and ensuring that employees always follow safety procedures is crucial.
Training and raising awareness for workers about the potential risks of benzenediamine is also an indispensable measure. Providing workers with knowledge about warning signs and how to handle incidents will help them be more proactive in protecting their own health. In addition, conducting regular health check-ups for workers helps to detect early signs of diseases related to benzenediamine exposure, allowing for timely intervention.
Finally, managers need to establish strict occupational hygiene procedures and ensure that workers are not exposed to benzenediamine for long periods, while also safely disposing of waste containing benzenediamine to avoid the risk of it spreading into the surrounding 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 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.
