How does Methyl methacrylate affect workers’ health?
Aug
Methyl methacrylate (C5H8O2) is a common chemical in the manufacturing industry, but do you know what serious health effects it can cause for workers? This article will help you understand the associated health risks and effective preventive measures.
1. What is Methyl methacrylate?
Methyl methacrylate (MMA) is a chemical compound with the formula C5H8O2, belonging to the ester group of methacrylic acid and methanol. It is a colorless, volatile liquid with a characteristic orange-like odor. MMA is commonly used in the production of acrylic plastics, paints, and other industrial products thanks to its transparent, durable properties and its ability to resist sunlight.
The molecular structure of MMA consists of a methyl ester group linked to an acrylic group, creating a compound with high polymerization potential. When MMA is stimulated by light or heat, it easily converts into poly(methyl methacrylate) (PMMA), a common plastic in many applications, from building materials to consumer products.
The popularity of MMA in the manufacturing industry is due to its superior properties such as heat resistance, impact resistance, and high durability. However, exposure to MMA needs to be carefully controlled as it can cause serious health problems if not handled properly. Therefore, understanding the characteristics of MMA is very important to ensure safety when working with this chemical.

2. Where does Methyl methacrylate originate from in the production process?
In the production process, Methyl methacrylate (MMA) can arise from various sources, mainly from processing and application stages in industries. MMA is typically produced through a chemical process called esterification, where methacrylic acid reacts with methanol under the action of a catalyst and high temperature. This is the main method for creating MMA on an industrial scale.
However, during the use of MMA in production, especially when it is polymerized to create poly(methyl methacrylate) (PMMA), sources of MMA generation can come from the release of MMA gas or vapor during heating and fabrication processes. Stages such as mixing, packaging, and transporting products containing MMA can also increase the emission of this compound into the air.
In addition, MMA can also arise from the processing of raw materials or during equipment cleaning activities using MMA. For example, when cleaning tools or equipment contaminated with MMA, MMA gas and vapor can be released into the environment. To manage and minimize the sources of MMA generation, manufacturers often apply emission control and occupational safety measures to limit exposure and protect workers’ health.
3. Industries that use Methyl methacrylate in production
Methyl methacrylate (MMA) is widely used in many industries and production fields thanks to its superior properties. One of the main applications of MMA is in the plastics industry. When polymerized, MMA creates poly(methyl methacrylate) (PMMA), a common acrylic plastic with transparent, durable, and easy-to-process characteristics. PMMA is used in manufacturing products such as acrylic glass, control panels, and glass substitute materials in the construction and interior decoration industry.
The paint and coatings industry also uses MMA to create paint and coating products with high durability, UV resistance, and water resistance. MMA provides good gloss and adhesion, making paint and coating products maintain a beautiful, bright appearance for a long time.
In the automotive industry, MMA is used to produce interior parts and components, including dashboards and decorative parts. The impact resistance and colorfast properties of PMMA make it an ideal material for these applications.
The electronics and refrigeration industry also uses MMA in the production of electronic device parts and components in cooling systems, thanks to its insulating and heat-resistant properties.
In addition, MMA is also applied in the medical industry, where it is used to produce medical devices, such as test tubes and prosthetic parts, thanks to its chemical resistance and non-toxic properties when processed correctly.
Thanks to its diversity in applications, MMA plays an important role in many different production fields, contributing to improving product quality and efficiency. However, the use of MMA needs to be carefully managed to ensure safety for workers and the environment.
4. How does Methyl methacrylate affect workers?
Methyl methacrylate (MMA) can cause a range of health problems for workers if not handled properly. Due to its volatile nature and ability to form toxic vapors, MMA can enter the body through inhalation, skin, or eyes. Prolonged exposure to MMA can lead to symptoms such as headache, dizziness, and nausea. These symptoms often appear when the concentration of MMA in the air exceeds permissible levels or when there is poor ventilation in the work area.
Long-term exposure to MMA can cause severe irritation to the skin and eyes. Skin irritation symptoms may include redness, itching, and rashes. In case of eye contact, MMA can cause eye redness, pain, and even corneal damage if not treated promptly. For those who are continuously or frequently exposed, the risk of developing skin problems like contact dermatitis is also higher.
In addition to skin and eye problems, MMA can also affect the respiratory system. When inhaling MMA vapor, workers may experience respiratory problems such as coughing, difficulty breathing, and bronchitis. In severe cases, continuous exposure can lead to lung damage and increase the risk of chronic respiratory diseases.
Furthermore, studies show that long-term exposure to MMA may pose a potential risk of causing cancer, although there is no clear evidence proving a direct link. However, to protect workers’ health, manufacturers and managers need to implement preventive measures, including providing personal protective equipment, ensuring good ventilation in the work area, and implementing procedures to monitor MMA concentrations in the air.
5. Permissible safe concentration of Methyl methacrylate for human exposure
The concentration of Methyl methacrylate (MMA) in the workplace air needs to be strictly controlled to ensure the health and safety of workers. Occupational health management agencies, such as the World Health Organization (WHO) and the Occupational Safety and Health Administration (OSHA), have set safe MMA concentration limits in the work environment.
According to OSHA standards, the maximum permissible concentration of MMA in the working air is 100 parts per million (ppm) over a continuous 8-hour work period. This is the average air concentration level that workers can be exposed to without experiencing serious health problems. However, the MMA concentration should not exceed 300 ppm within a 15-minute period, known as the short-term exposure limit (STEL). Maintaining these concentration levels is important to minimize the risk of health problems related to MMA exposure.
Protective measures such as good ventilation systems, the use of personal protective equipment, and implementing regular MMA concentration checks in the air are very important to maintain MMA concentrations within safe limits. Providing information and training to workers about the risks and preventive measures when working with MMA also contributes significantly to protecting their health.
In addition to complying with MMA concentration standards, managers also need to ensure that safe work methods and hygiene procedures are properly implemented. Regularly using MMA concentration testing equipment will help detect any increase in concentration promptly and implement necessary corrective measures to protect workers from harmful effects.
At a basic level, if working in an industrial environment, it is important to comply with safety standards and limit exposure to Methyl methacrylate. 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 minimize the impact of Methyl methacrylate on workers’ health
To minimize the impact of Methyl methacrylate (MMA) on workers’ health, applying preventive and control measures is essential. First, maintaining an effective ventilation system in the work area is important. A ventilation system helps reduce the concentration of MMA in the air by removing MMA vapor and providing fresh air, thereby reducing the risk of exposure for workers. This may include installing exhaust fans, air extraction systems, and air filtration devices.
Using personal protective equipment also plays an important role in protecting workers’ health. Equipment such as dust masks, protective gloves, safety goggles, and protective clothing should be provided and used correctly. This equipment helps prevent direct contact with MMA, protecting the skin, eyes, and respiratory tract from exposure to harmful vapors.
Training and raising awareness for workers about the risks associated with MMA and preventive measures are very important. Workers need to be instructed on how to use protective equipment, emergency handling procedures, and safe working methods. Periodic training programs help workers update the knowledge and skills needed to work safely with MMA.
For production facilities, implementing procedures to check MMA concentrations in the air is necessary to ensure that the concentration levels do not exceed safe limits. Measuring and testing devices should be used regularly to monitor MMA concentrations and detect any increases promptly. When the MMA concentration exceeds the permissible level, corrective measures must be taken, such as increasing ventilation or temporarily stopping production until the MMA concentration returns to a safe level.
In addition, establishing and implementing regular hygiene and equipment maintenance procedures is necessary to ensure a clean and safe working environment. Work areas should be cleaned regularly to remove MMA dust and vapor, while equipment should be inspected and maintained to ensure it operates effectively.
By applying these measures, production facilities can significantly minimize the impact of MMA on workers’ health, ensure a safe working environment, and protect the long-term health of employees.
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 needs to be provided periodically and regularly to ensure understanding and compliance with safety rules.
Periodically organize workplace environment monitoring in factories and enterprises, collect and analyze factors harmful to workers, thereby adjusting to reduce the hazard level to prevent occupational diseases for them.
