How Does Methacrylic Acid Affect Workers’ Health?
Nov
Methacrylic acid, an important chemical compound in industry, plays a significant role in the production of many products from plastics to adhesives. However, unsafe exposure to methacrylic acid can pose considerable challenges to workers’ health. This article will investigate and analyze how methacrylic acid affects workers’ health, from the potential risks to the safety measures that need to be implemented to protect the labor community from the negative effects of this substance.
1. What is Methacrylic acid?
Methacrylic acid (C4H6O2) is a carboxylic acid containing a methacrylic group in its molecular structure. It is an important chemical compound used primarily in the chemical and manufacturing industries. Methacrylic acid is commonly used to produce polymethyl methacrylate (PMMA), a well-known acrylic plastic, as well as in the production of adhesives and glues.
When working with methacrylic acid, safety measures must be taken as it can cause irritation and affect health if directly contacted or its vapors are inhaled. In general, the use of methacrylic acid requires strict adherence to safety rules to protect workers and the environment.

2. Where does Methacrylic acid originate from in the production process?
Methacrylic acid (C4H6O2) is typically produced through the oxidation of methyl methacrylate (MMA), an ester of methacrylic acid. Methyl methacrylate is a primary compound created from acetone and methanol during the oxidation of acetone cyanohydrin. The main production process includes the following key steps:
- Creation of acetone cyanohydrin: A reaction between acetone, hydrocyanic acid, and sulfuric acid leads to the formation of acetone cyanohydrin.
- Conversion of acetone cyanohydrin to methyl methacrylate: Acetone cyanohydrin is converted to methyl methacrylate through various chemical reaction steps.
- Oxidation of methyl methacrylate to methacrylic acid: Methyl methacrylate then undergoes an oxidation process to form methacrylic acid.
This process not only ensures the supply of methacrylic acid but also produces methyl methacrylate, a key raw material for the production of polymethyl methacrylate (PMMA) and many other products in the chemical and polymer industries. However, during this production process, safety measures must be implemented to ensure the safety of workers and the environment.
3. Industries that use Methacrylic acid in production
Methacrylic acid (C4H6O2) is used in many different industries due to its diverse properties and versatility. Here are some of the main industries where Methacrylic acid is commonly used in production:
- Plastics Industry:
- Production of polymethyl methacrylate (PMMA), a shiny and transparent acrylic plastic used in glass, mobile phone cases, lights, and many other applications.
- Adhesives and Glues Industry:
- Methacrylic acid is used in the production of adhesives and glues with heat-resistant and chemical-resistant properties.
- Additives Industry:
- Used in the production of additives for paints and inks, helping to improve the properties and adhesion of the product.
- Printing Ink Industry:
- Methacrylic acid can be used as a component in water-resistant and scratch-resistant printing inks, as well as providing adhesive properties.
- Antioxidant Industry:
- Production of antioxidants and anti-pollutants for fuels and oils.
- Oils and Greases Industry:
- Methacrylic acid can be used in the production of smoothing agents and thickeners.
- Water Treatment Industry:
- Used in the production of flocculants for wastewater treatment.
4. How does Methacrylic acid affect workers
Methacrylic acid can affect the health of workers if they come into direct contact with it or inhale its vapors without proper safety measures. Here are some of the main effects of Methacrylic acid on workers:
- Skin and Eye Irritation:
- Direct contact with Methacrylic acid can cause irritation to the skin and eyes. This can lead to swelling, pain, redness, and in severe cases, skin and eye damage can occur.
- Respiratory Issues:
- Inhaling Methacrylic acid vapors can irritate the respiratory tract, leading to problems such as coughing, throat discomfort, and in severe cases, difficulty breathing.
- Poisoning:
- Long-term or high-level exposure to Methacrylic acid can cause poisoning. Symptoms may include headache, nausea, and fatigue.
- Impact on the Nervous System:
- Methacrylic acid can have an impact on the nervous system, especially with long-term or high-level exposure.
To minimize the health risks from Methacrylic acid, safety measures must be implemented, including the use of personal protective equipment such as respirators, gloves, and safety glasses. Additionally, implementing safe work procedures, risk communication, and educating workers about safety are important to prevent the negative health effects of Methacrylic acid.
5. Permissible safe concentration of Methacrylic acid for human exposure
There is no single general safety threshold for methacrylic acid concentration that has no effect on human health that has been precisely determined by international organizations such as the World Health Organization (WHO) or the United States Environmental Protection Agency (EPA). Safety thresholds can vary depending on the type of exposure (e.g., skin, inhalation, ingestion), duration of exposure, and working conditions.
Instead, safety standards are often determined by national or regional organizations and are provided in the product’s safety data sheets. For methacrylic acid, manufacturers and industrial regulatory agencies often determine safety thresholds based on scientific research and occupational safety criteria.
At a basic level, if working in an industrial environment, adhering to safety standards and limiting exposure to Methacrylic acid 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 minimize the impact of Methacrylic acid on workers’ health
To minimize the impact of Methacrylic acid on workers’ health, you can implement the following safety measures:
- Use Personal Protective Equipment (PPE):
- Wear a respirator, gloves, protective clothing, and safety glasses to protect the skin, eyes, and respiratory tract from direct contact with Methacrylic acid.
- Implement Safe Work Procedures:
- Adhere to safety rules and safe work procedures when working with Methacrylic acid. This includes using personal protective equipment, controlling substance release, and keeping the work environment clean.
- Adjust Exposure Scale and Duration:
- Limit exposure time and reduce the amount of Methacrylic acid used in a specific period to minimize risk.
- Safety Management Systems:
- Establish safety management systems to ensure the storage, use, and handling of Methacrylic acid are done safely and effectively.
- Occupational safety training:
- Provide adequate training to workers on the risks of Methacrylic acid, as well as how to use and protect themselves.
- Environmental Control:
- Ensure the work environment has a good ventilation system to reduce the absorption of Methacrylic acid and lessen the risk of inhaling its vapors.
- Health Monitoring:
- Conduct periodic health monitoring for workers exposed to Methacrylic acid to detect any potential health problems early.
- Periodically organize working 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.
