How does tetrachlorophenol affect workers’ health?
Apr
2,3,4,6-Tetrachloro phenol (C6H2Cl4O) is a common chemical in industrial production but poses significant risks to workers’ health. This article analyzes its potential harmful effects and outlines effective protective measures when handling this chemical in factories.
1. What is 2,3,4,6-Tetrachloro phenol?
2,3,4,6-Tetrachloro phenol, with the chemical formula C₆H₂Cl₄O, is a chlorinated derivative of phenol. In this molecule, the hydroxyl group (-OH) is attached to the benzene ring at position 1, while four chlorine atoms (Cl) replace hydrogen atoms at positions 2, 3, 4, and 6.
This structure results in a compound with unique chemical properties, having a density of 1.6 g/cm³ and a melting point of around 70°C.
It is mainly used in industry as a disinfectant and wood preservative, and can also appear as a by-product in the synthesis of other chemicals.

2. How is 2,3,4,6-Tetrachloro phenol generated in production?
2,3,4,6-Tetrachloro phenol is typically formed as a by-product of phenol chlorination. This reaction is conducted in an acidic environment using catalysts such as hydrochloric acid or sulfuric acid at high temperatures.
The process can also produce other isomers like 2,3,5,6-Tetrachloro phenol and pentachlorophenol depending on reaction conditions. If not properly managed, these by-products can contaminate the production environment and pose safety hazards.
3. Industries using 2,3,4,6-Tetrachloro phenol
This chemical is mainly used in the production of pesticides and wood preservatives.
Pesticides containing 2,3,4,6-Tetrachloro phenol help eliminate fungi and insects harmful to crops.
In wood preservation, it protects against termites and mold, extending the lifespan of wood products.
Strict compliance with occupational safety and environmental regulations is necessary to prevent adverse effects on human health and ecosystems.
4. Health impacts of 2,3,4,6-Tetrachloro phenol on workers
Exposure can cause irritation to the skin, eyes, and respiratory tract, resulting in dermatitis, conjunctivitis, and respiratory inflammation.
Long-term or repeated exposure may affect liver and kidney functions, causing cellular damage. Studies also suggest neurological impacts, including dizziness, nausea, and fatigue.
5. Safe exposure limits for 2,3,4,6-Tetrachloro phenol
Currently, no specific exposure limits are defined in Vietnamese legislation. International standards and good industry practices should be followed to minimize risks. 
At a basic level, adherence to safety standards and limiting exposure to 2,3,4,6-Tetrachloro phenol is essential. Organizations like the U.S. Occupational Safety and Health Administration (OSHA) provide guidance to protect workers from chemical hazards.
6. Measures to minimize the impact of 2,3,4,6-Tetrachloro phenol
Effective strategies include:
Engineering controls: Implement local exhaust ventilation in areas generating vapors or dust. Use closed production systems and automation to reduce direct contact.
Personal protective equipment (PPE): Workers should wear respirators, gloves, protective clothing, and safety goggles, especially when handling chemical products or cleaning equipment.
Training and awareness: Regular training on health risks, proper use of PPE, recognizing symptoms, and emergency response procedures helps workers actively protect themselves.
Health monitoring: Conduct regular health check-ups for liver, kidney, and nervous system function to detect early signs of chemical exposure.
Spill management and workplace hygiene: Develop response plans for leaks or spills, and ensure workers clean themselves and change protective clothing after shifts.
Periodic occupational safety training and workplace environmental monitoring are essential to prevent occupational diseases.
