Apr
In this article, we will explore the impact of the chemical oo-Diethyl s-ethyl thiomethyl phosphorothioate (C7H17O3PS2) on workers’ health in manufacturing plants where this chemical is used. The dangerous effects and prevention measures will be clarified, with protecting workers’ health as the top priority.
1. What is oo-Diethyl s-ethyl thiomethyl phosphorothioate?
Oo-Diethyl s-ethyl thiomethyl phosphorothioate, with the chemical formula C7H17O3PS2, is an organic compound belonging to the phosphorothioate group. Its molecular structure consists of seven carbon atoms (C7), seventeen hydrogen atoms (H17), three oxygen atoms (O3), one phosphorus atom (P), and two sulfur atoms (S2). The main functional group in the molecule is the phosphorus group (P) bonded to two thiomethyl groups (-CH2SH) through single bonds, forming the characteristic structure of this compound.
This molecular formula indicates that the compound contains a central phosphorus atom surrounded by organic and sulfur functional groups, giving it unique chemical properties. The molecular structure of oo-Diethyl s-ethyl thiomethyl phosphorothioate can be modeled and visualized using specialized chemical software, helping to better understand the shape and atomic connections within the molecule.

2. Where does oo-Diethyl s-ethyl thiomethyl phosphorothioate originate during production?
This chemical is commonly generated during the synthesis of phosphorothioate compounds, especially when reacting diethyl phosphite with thiomethyl-containing compounds. This synthesis occurs in industrial settings where raw materials are combined through chemical reactions to produce the final product.
During this process, the compound may appear as a byproduct or a main component, depending on reaction conditions and the ratio of raw materials used. Strict control of factors such as temperature, pressure, and reactant ratios is essential to ensure product quality and production efficiency.
Additionally, in post-synthesis processing and handling, this compound may be blended with other components to create pesticides or plant protection products, thereby continuing to occur and persist in the production environment.
3. Industries using oo-Diethyl s-ethyl thiomethyl phosphorothioate in production
This chemical is mainly applied in agriculture, particularly in the production of pesticides and plant protection products. In pesticide manufacturing plants, it is used to synthesize products capable of eliminating harmful pests, improving crop yield and quality.
Moreover, on farms, farmers use this chemical to protect crops from pest attacks, thereby enhancing agricultural productivity and product quality. The use of this compound in production requires strict control to ensure worker safety and environmental protection.
4. How oo-Diethyl s-ethyl thiomethyl phosphorothioate affects workers
This chemical can seriously affect workers’ health when exposed directly or over long periods.
Inhalation or skin contact with this compound can lead to acute poisoning symptoms such as headache, dizziness, nausea, vomiting, abdominal pain, diarrhea, convulsions, and in severe cases, coma or death.
It can also irritate the eyes and skin, causing inflammation, redness, itching, or rash.
Prolonged exposure may particularly affect the nervous system, causing neurological impairment and other serious health issues.
5. Safe exposure limits for oo-Diethyl s-ethyl thiomethyl phosphorothioate
In the workplace, the permissible exposure limit (PEL) for this chemical is regulated by the U.S. Occupational Safety and Health Administration (OSHA) and the U.S. Centers for Disease Control and Prevention (CDC – NIOSH). Both agencies set the maximum allowable exposure at 0.1 mg/m³, calculated as an 8-hour time-weighted average (TWA), with the notation “skin,” meaning it can be absorbed through the skin.
Additionally, the immediately dangerous to life or health (IDLH) concentration is defined as 10 mg/m³, indicating a level that can pose immediate threats to life or health.
However, these standards mainly apply in the U.S. Currently, there is no specific information on safe exposure limits for oo-Diethyl s-ethyl thiomethyl phosphorothioate under Vietnamese law.
At a basic level, when working in industrial environments, complying with safety standards and limiting exposure to oo-Diethyl s-ethyl thiomethyl phosphorothioate is important. Organizations like the U.S. Occupational Safety and Health Administration (OSHA) provide safety guidelines and principles to protect workers from the harmful effects of chemicals.
6. Measures to minimize the impact of oo-Diethyl s-ethyl thiomethyl phosphorothioate on workers’ health
To minimize the impact of this chemical on workers’ health, several safety measures should be implemented during production.
According to Circular 48/2020/TT-BCT, before allowing workers to enter confined spaces with toxic chemicals, the concentration of toxic chemicals in the air must be measured and decontaminated appropriately to ensure residual concentrations are below permissible exposure limits. If the toxic concentration cannot be reduced to safe levels, appropriate personal protective equipment must be provided, and at least two workers should be present for alarm and timely emergency response.
Additionally, production facilities need to develop and implement chemical incident prevention and response plans, including training staff on response procedures, handling methods, and providing sufficient protective equipment for those involved in incident management.
Compliance with these regulations helps reduce risks and protect workers’ health when working with hazardous chemicals.
Occupational safety training: Workers need to be trained and educated about the risks and safety measures when handling this chemical. Training should be provided regularly to ensure understanding and adherence to safety rules.
Regular workplace environment monitoring in factories involves collecting and analyzing harmful factors affecting workers, then adjusting to reduce hazards to prevent occupational diseases.
