How does Dibutyltin oxide affect workers’ health?
May
Explore the impact of Dibutyltin oxide (C8H18OSn) on the health of workers in a production environment. This article will explain the effects of this chemical and its potential health impacts, thereby providing important information for workers and occupational safety professionals.
1. What is Dibutyltin oxide?
Dibutyltin oxide (DBTO) is an organotin compound with the chemical formula C8H18OSn. It is formed from two butyl groups (C4H9) bonded to a tin (Sn) atom through an oxygen (O) atom. DBTO is a colorless to light yellow liquid with a mild odor.
DBTO is used in industry for various purposes. One of its main applications is as a PVC stabilizer. PVC (polyvinyl chloride) is a widely used plastic, but it is not thermally stable and can degrade over time. DBTO is added to PVC to prevent this degradation process and improve the material’s lifespan.
In addition, DBTO is also used as a lubricant and anti-wear agent. It can be used in greases and other lubricating products to reduce friction and wear between contacting surfaces. DBTO is also used in some other applications, such as flame retardants, fungicides, and catalysts.

2. Where does Dibutyltin oxide originate from in the production process?
Dibutyltin oxide (DBTO) is not a main product in any production process but is often generated as an unwanted byproduct. Some potential sources of DBTO generation during production include:
- Monoalkyltin production: The production process of monoalkyltin compounds, such as monobutyltin (MBT), can sometimes generate DBTO as a byproduct. MBT is used in industry as a PVC stabilizer and catalyst.
- Polyvinyl chloride (PVC) production: As mentioned earlier, DBTO is used as a PVC stabilizer. However, during PVC production, a small amount of DBTO can also be formed due to unwanted reactions between other components.
- Rubber product production: DBTO is sometimes used as an additive in the production of rubber products. However, this production process can also generate a small amount of DBTO as a byproduct.
- Decomposition of other butyltin compounds: Some other butyltin compounds, such as dibutyltin dichloride (DBTC), can decompose over time to form DBTO.
Controlling and limiting the formation of DBTO in these production processes is very important to minimize hazardous waste and protect the environment. Manufacturers can adopt cleaner production processes and optimize reactions to minimize the formation of DBTO as a byproduct.
3. Industries that use Dibutyltin oxide in production
Dibutyltin oxide (DBTO) is used in many different manufacturing industries. Here are some examples:
- Plastics manufacturing industry: DBTO plays an important role in the plastics manufacturing industry, especially in the production of polyvinyl chloride (PVC). As mentioned earlier, DBTO is used as a PVC stabilizer, helping to prevent degradation and improve the material’s lifespan. PVC is widely used in the production of many products such as water pipes, electrical wires, windows, furniture, and toys.
- Rubber manufacturing industry: DBTO is sometimes used as an additive in the production of rubber products. It helps to improve the durability and anti-aging properties of rubber. However, the use of DBTO in this industry is currently being restricted due to environmental and health concerns.
- Lubricant and grease manufacturing industry: DBTO has lubricating and anti-wear properties, so it is used in the production of some types of lubricants and greases. However, the current trend is to replace DBTO with safer alternatives for the environment and human health.
- Other industries: In addition, DBTO is also used in some other manufacturing industries in smaller quantities, such as in the production of flame retardants, fungicides, and catalysts. However, depending on the environmental and health regulations of each country, the use of DBTO in these industries may be restricted or completely banned.
4. How does Dibutyltin oxide affect workers?
Dibutyltin oxide (DBTO) is a chemical compound that can cause many negative health effects for workers if they come into direct contact with it or inhale its dust during work. Here are some of the effects of DBTO on different systems in the body:
- Respiratory system: When DBTO dust is inhaled, the fine particles of this substance can go deep into the lungs, causing respiratory irritation and leading to lung problems such as bronchitis, difficulty breathing, and in severe cases, can cause chronic obstructive pulmonary disease (COPD).
- Skin: DBTO can cause skin irritation upon direct contact. Frequent or prolonged contact with DBTO can cause skin problems such as rashes, itching, and may even lead to allergic dermatitis.
- Other organs: In addition, DBTO can also be absorbed into the body through the respiratory tract or skin and affect many different organs. Potential risks include damage to the heart, kidneys, nervous system, causing headaches, dizziness, nausea, and fatigue. In some cases, DBTO can cause endocrine-disrupting effects, affecting the reproductive system.
The severity of these effects depends on many factors such as the concentration of DBTO exposure, the duration of exposure, and the overall health status of the worker. Therefore, limiting exposure to DBTO and using appropriate protective measures are necessary to ensure the health safety of workers.
5. Permissible safe concentration of Dibutyltin oxide for human exposure
Dibutyltin oxide (DBTO) is a chemical compound that can cause adverse health effects to humans if exposed at high concentrations. Therefore, establishing a safe (occupational) exposure limit for DBTO is very important to protect worker health.
Currently, according to reputable organizations for occupational safety and health, there is no official exposure limit standard set for DBTO. However, some reference sources mention reference concentrations such as:
NIOSH (National Institute for Occupational Safety and Health, USA) recommends an exposure limit for DBTO of 0.1 mg/m³ for 8 hours/day and 40 hours/week. The DFG (Deutsche Forschungsgemeinschaft – German Research Foundation) classifies DBTO as a substance with low acute toxicity potential and places it in Group C (substances with a recommended exposure limit of 25 mg/m³). Note that these are only reference concentrations, and competent health authorities in Vietnam may have their own regulations regarding exposure limits to DBTO. Businesses need to consult the current Vietnamese legal regulations to ensure safety for their workers.
On a basic level, if working in an industrial environment, adhering to safety standards and limiting exposure to Dibutyltin oxide is important. Organizations like 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 effects of Dibutyltin oxide on worker health
Measures to mitigate the effects of Dibutyltin oxide (DBTO) on the health of workers are an extremely important issue in the work environment. DBTO is a chemical compound often used in manufacturing and industry as a stabilizer, catalyst, and waterproofing agent. However, it has been identified as having the potential to harm human health upon long-term exposure.
To minimize the risk of DBTO’s effects on worker health, the following measures should be applied. First, safety measures must be implemented during the handling of DBTO, including the use of personal protective equipment such as masks, gloves, and chemical-resistant gowns. Ensuring that workers do not have direct contact with DBTO is extremely important.
Second, clear regulations regarding the use and handling of DBTO in the work environment must be established. Employees need to be trained on the health effects of DBTO and the necessary preventive measures. They should also be instructed on how to handle materials containing DBTO safely and effectively.
Third, it is important to regularly check the level of worker exposure to DBTO. Periodic measurement and monitoring will help in implementing timely intervention measures if necessary to protect employee health.
Finally, implementing proper industrial hygiene measures is also a necessary factor. This includes cleaning work areas, disposing of waste containing DBTO safely and properly, and minimizing the dispersal of this substance into the work 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 compliance with safety rules.
Periodically organize workplace environment monitoring in factories and enterprises, collect and analyze factors harmful to workers, thereby adjusting to reduce hazard levels to prevent occupational diseases for them.
