Azinphos-ethyl (C12H16N3O3PS2) is a chemical commonly used in the manufacturing industry, but it also poses many potential risks to the health of workers. This article will explore in detail the impact of azinphos-ethyl on workers in factory environments where this chemical is used.
1. What is azinphos-ethyl?
Azinphos-ethyl, with the chemical formula C₁₂H₁₆N₃O₃PS₂, is an organophosphate compound widely used as an insecticide. Its molecular structure consists of a benzotriazine group linked to a phosphorodithioate group through a methyl bridge. This formula reflects the combination of carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur, creating a molecule with a molar mass of approximately 345.37 g/mol.

2. Where does azinphos-ethyl originate from in the production process?
During the production process, azinphos-ethyl can be generated from various sources. In pesticide manufacturing plants, azinphos-ethyl is synthesized from chemical raw materials. This process involves complex chemical reactions to create azinphos-ethyl. Additionally, during packaging and storage, leaks or spills of azinphos-ethyl can occur, leading to the presence of this chemical in the work environment. Therefore, adherence to safety procedures and quality control in production is crucial to minimize the risk of azinphos-ethyl generation and to protect workers’ health.

3. Industries that use azinphos-ethyl in production
Azinphos-ethyl is primarily used in the agricultural sector, especially in the production and preservation of crops. This chemical is used to control pests, particularly harmful insects on crops such as vegetables, rice, and fruit trees. Pesticide manufacturing plants and agricultural production facilities are also places where azinphos-ethyl is used to protect crops from pest attacks.
Furthermore, azinphos-ethyl is used in some food and pharmaceutical processing industries to control pests during the storage of raw materials. Some research and development facilities also use this chemical to test and evaluate the effectiveness of insect control methods.
4. How does azinphos-ethyl affect workers?
When workers are exposed to azinphos-ethyl, they can experience serious health effects. This chemical, due to the toxic nature of the organophosphate group, can enter the body through the skin, inhalation, or the digestive tract. Inhaling dust or vapor of azinphos-ethyl in the workplace can cause symptoms such as headache, dizziness, difficulty breathing, nausea, and fatigue.
Moreover, with long-term exposure, this chemical can affect the central nervous system, causing neurological dysfunction, seizures, and even respiratory failure. Studies have also shown that azinphos-ethyl can cause problems with the liver, kidneys, and digestive system if exposure is at high levels or over a long period.
5. Permissible safe concentration of azinphos-ethyl for human exposure
The permissible safe concentration of azinphos-ethyl for human exposure is regulated by occupational safety and health standards. According to international organizations such as the World Health Organization (WHO) and the U.S. Environmental Protection Agency (EPA), the maximum concentration of azinphos-ethyl in the workplace air should not exceed 0.1 mg/m³. This is a safe concentration aimed at minimizing the risk of health effects on workers during their work shift.
In addition, regulations also require that the residual level of azinphos-ethyl in food does not exceed the permissible limit to ensure consumer safety. Although the permissible concentration is determined based on scientific research and testing, strict monitoring and ensuring safety measures are always important factors to avoid long-term harm to human health.

On a basic level, if working in an industrial environment, it is important to adhere to safety standards and limit exposure to Azinphos-ethyl. Organizations like 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 azinphos-ethyl on workers
To minimize the health effects of azinphos-ethyl on workers, protective measures must be strictly implemented during production and use. First, providing adequate personal protective equipment (PPE) for workers is very important. Equipment such as respirators, gloves, protective clothing, and goggles helps prevent direct contact with the chemical, especially in areas with high concentrations of azinphos-ethyl.
Second, improving the ventilation system in manufacturing plants or work areas also plays a significant role in reducing the concentration of the chemical in the air, thereby reducing the risk of inhaling dust or vapor of azinphos-ethyl. In addition, factories need to implement periodic environmental monitoring of the workplace to ensure that the concentration of this chemical does not exceed the permissible level.
Furthermore, training and instructing workers on safety measures when working with chemicals is essential. Workers need to be equipped with knowledge on how to use and store chemicals correctly, as well as how to handle incidents such as spills or unintentional exposure. Finally, adhering to the regulations on the maximum permissible concentration of azinphos-ethyl in the work environment and in food is a crucial factor in protecting the health of workers and the community.
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 occupational environment monitoring in factories and enterprises, to collect and analyze factors harmful to workers, thereby adjusting to reduce the level of risk to prevent occupational diseases for them.
