How does Difluoro Ethane affect workers’ health?
Apr
Difluoro Ethane (C₂H₄F₂) is widely used in industry, but does this chemical have any effect on the health of workers? This article will analyze the potential impacts of exposure, health risks, and safety measures to help workers operate effectively in environments with this chemical.
1. What is Difluoro Ethane?
Difluoro Ethane, with the chemical formula C₂H₄F₂, is an organic compound belonging to the hydrofluorocarbon (HFC) group. It is a colorless, faintly odorous gas that is easily liquefied.
In industry, Difluoro Ethaneis widely used as a refrigerant (known as R-152a or HFC-152a) and as a propellant in aerosol products. The specific isomer used for these applications is 1,1-Difluoro Ethane.
With a molecular structure consisting of two carbon atoms, four hydrogen atoms, and two fluorine atoms, Difluoro Ethane has characteristic physicochemical properties, including a melting point of approximately -117°C and a boiling point of approximately -24.7°C. These features make it a popular choice in many industrial applications.

2. What are the sources of Difluoro Ethane in the production process?
In industrial production, the compound C₂H₄F₂ is created and used primarily in industries related to chemicals, refrigeration, and aerosol products. One of the common sources is the chemical synthesis process in plants that produce solvents, refrigerants, and propellants. This compound is typically prepared from the reaction between ethylene (C₂H₄) and hydrogen fluoride (HF) under tightly controlled conditions.
Additionally, this gas can be released from aerosol can production lines, where it is used as a propellant in products such as hairspray, insecticide sprays, and electronic cleaning sprays. The process of filling and packaging aerosol products can lead to small amounts leaking into the air.
In the refrigeration industry, this compound is used as a replacement for older refrigerants that are harmful to the environment. Air conditioning systems and freezers using C₂H₄F₂ may release the gas during refrigerant charging, maintenance, or due to equipment leaks. If not properly controlled, the amount of gas released can affect the work environment and the health of workers.
3. Industries that use Difluoro Ethane in production
In the chemical industry, the compound C₂H₄F₂ is used as a raw material for producing solvents and as a propellant in aerosol cans. Factories that manufacture hairspray, insecticide sprays, electronic equipment cleaning sprays, and other aerosol products all use this compound to ensure optimal spray pressure.
The refrigeration industry also widely uses C₂H₄F₂ as a refrigerant in air conditioning systems, freezers, and refrigerators. It is one of the replacements for previous refrigerants that posed a risk to the ozone layer. During operation, maintenance, or refrigerant charging, this compound can leak into the work environment.
The field of electronic component manufacturing and high technology also involves the presence of C₂H₄F₂. This compound is used as a cleaning solvent for microcircuits and electronic components due to its ability to evaporate quickly without leaving residue. Technology equipment production lines often use gas cleaning methods to remove dust and grease from component surfaces.
Furthermore, in some specific industries, C₂H₄F₂ is also used as a foaming agent in the production of plastics and insulating materials. Thanks to its rapid evaporation and expansion properties, this compound helps improve the texture of the final product, meeting technical requirements during the manufacturing process.
4. How does Difluoro Ethane affect workers?
Exposure to C₂H₄F₂ in the workplace can cause various health effects, depending on the concentration and duration of exposure. When inhaling this gas at low concentrations, workers may feel dizzy, have a headache, experience nausea, and lose their balance due to its effect on the central nervous system. If exposed to higher concentrations for a long period, there is a risk of decreased consciousness or even fainting.
This compound can also cause irritation upon direct contact with the skin and eyes. People who frequently work in an environment with C₂H₄F₂ may experience dry skin, redness, or contact dermatitis if appropriate protective measures are not taken. When it gets into the eyes, this compound can cause severe irritation, leading to tearing, redness, and an uncomfortable burning sensation.
In the event of a high-concentration leak in an enclosed space, this gas can reduce the oxygen concentration in the air, posing a risk of asphyxiation. Workers in areas where C₂H₄F₂ is used without good ventilation may experience difficulty breathing, a rapid heartbeat, and loss of consciousness.
Moreover, this compound has flammable properties, increasing the risk of fire and explosion in the workplace. If a fire occurs, its decomposition products can generate toxic gases, which can severely affect the respiratory tract of workers upon inhalation. These impacts require strict control measures to mitigate risks to health and occupational safety.
5. Permissible safe concentration of Difluoro Ethane for human exposure
Currently, specific information regarding the safe exposure concentration for Difluoro Ethane has not been found in Vietnamese legal documents. Therefore, determining the safe exposure level for Difluoro Ethane requires referencing international standards and best practices in the industry.
According to the U.S. Occupational Safety and Health Administration (OSHA), the permissible exposure limit (PEL) for C₂H₄F₂ is 500 parts per million (ppm) as an 8-hour time-weighted average.
However, the American Conference of Governmental Industrial Hygienists (ACGIH) has proposed a threshold limit value (TLV) for C₂H₄F₂ of 100 ppm as an 8-hour time-weighted average.
The difference between these limits reflects different views on safe exposure levels. Therefore, companies should adhere to the specific regulations of their country or region and apply appropriate protective measures to ensure the safety of workers when handling C₂H₄F₂.
Basically, when working in an industrial environment, it is important to adhere to safety standards and limit exposure to Difluoro Ethane. Organizations such as the Occupational Safety and Health Administration (OSHA) in the United States provide guidelines and safety principles to protect workers from the negative effects of chemical substances.
6. Measures to minimize the health effects of Difluoro Ethane on workers
To minimize the health effects of C₂H₄F₂ on workers, it is necessary to apply engineering and organizational control measures to limit direct contact with this chemical. The ventilation system in the workplace must be designed to ensure good air circulation, helping to reduce the concentration of the gas in enclosed environments. Areas with a high risk of gas dispersion should be equipped with local exhaust systems to prevent chemical accumulation.
Workers in environments where C₂H₄F₂ is used must be fully equipped with personal protective equipment such as organic vapor respirators, chemical-resistant gloves, and safety goggles. These measures help limit the risk of inhaling toxic gas or direct contact through the skin and eyes. In addition, specialized protective clothing should also be used to reduce the risk of chemical absorption through the skin during prolonged work.
Occupational safety training is a crucial element to help workers become fully aware of the risks of exposure to C₂H₄F₂ and how to handle emergency situations. Training courses should focus on the proper use of protective equipment, safe work methods, and first aid measures in case of exposure. Specifically, there must be clear instructions on how to respond to a gas leak to minimize risks from the outset.
Furthermore, monitoring the work environment with gas concentration measurement devices is necessary to ensure that exposure levels remain within safe limits. Businesses need to conduct periodic inspections, maintain ventilation systems, and replace protective equipment as needed to maintain safe working conditions for employees.
Occupational Safety Training: Workers need to be trained and educated about the risks and safety measures when working with this chemical. This training should be provided periodically and regularly to ensure understanding and proper adherence to safety rules.
Periodically conduct workplace environment monitoring in factories and enterprises, collecting and analyzing factors harmful to workers, thereby adjusting to reduce hazard levels to prevent occupational diseases for them.
