How does Vinyl Acetylene affect workers’ health?
Feb
Vinyl acetylene (1-Buten-3-yne) (C4H4) is a crucial industrial chemical but poses significant health risks to workers. When exposed in a factory environment, it can cause irritation, poisoning, and long-term effects. So, what are the specific harms, and how can you protect yourself? Let’s find out now!
1. What is Vinyl acetylene (1-Buten-3-yne)?
Vinyl acetylene, also known as 1-buten-3-yne, is an organic compound with the chemical formula C₄H₄. It is an unsaturated hydrocarbon containing both a double bond and a triple bond in its molecule, belonging to the simplest group of enynes. Under normal conditions, vinyl acetylene exists as a colorless, highly flammable gas with a characteristic mild odor. This compound was formerly used in the polymer industry.

2. Where does Vinyl acetylene (1-Buten-3-yne) originate from in the production process?
This compound often appears during the production of chemicals and polymers containing unsaturated structures. One of the main sources of vinyl acetylene is in ethylene or propylene production plants, where cracking reactions occur at high temperatures. When heavy hydrocarbons are cracked to produce lighter products like ethylene, propylene, and butadiene, vinyl acetylene can be formed as a byproduct. Additionally, the production of polymers such as polystyrene or polyethylene can also generate vinyl acetylene if the reaction conditions are suitable.
3. Industries that use Vinyl acetylene (1-Buten-3-yne) in production
This compound is used in various industries, especially in the production of chemicals and polymers. In the petrochemical industry, it is used as an intermediate to synthesize important organic compounds like butadiene, a key component in the production of synthetic rubber. Furthermore, the plastics and polymer manufacturing industry utilizes this compound in creating materials with high elasticity and durability.
Besides that, the paint and adhesive industry may also use this compound to create products with high adhesion and good heat resistance. In the field of dye and specialty chemical production, it is used to create compounds with special properties, serving many different applications in industry and research.
4. How does Vinyl acetylene (1-Buten-3-yne) affect workers?
This compound can seriously affect the health of workers upon exposure in a production environment. At low concentrations, it can cause irritation to the eyes, skin, and respiratory tract, leading to symptoms such as stinging eyes, coughing, sore throat, and difficulty breathing. If exposure is prolonged or at high concentrations, it can cause damage to the central nervous system, leading to dizziness, nausea, headaches, and loss of consciousness.
Inhaling the gas or vapor of this compound for a long time can affect the lungs, causing respiratory inflammation and reducing lung function. Direct contact with the skin can cause irritation, dryness, or even chemical burns if at high concentrations. Additionally, some studies suggest that long-term exposure may increase the risk of chronic diseases, including liver and kidney damage.
5. Permissible safe concentration of Vinyl acetylene (1-Buten-3-yne) for human exposure
Currently, standards for safe exposure concentrations for this compound in the working environment have not been specifically regulated in Vietnamese legal documents. However, according to Circular 10/2019/TT-BYT of the Ministry of Health, the Short-Term Exposure Limit (STEL) is defined as the concentration value of a substance in the workplace air, averaged over a 15-minute period, which workers are not allowed to be exposed to beyond this threshold. If the concentration of the substance in the work environment is between the TWA and STEL limits, workers are not allowed to be exposed for more than 15 minutes per instance and not more than 4 times per work shift, with intervals between exposures of at least 60 minutes.
Due to the lack of specific information on the permissible exposure limit for vinyl acetylene, applying general preventive measures for volatile and potentially harmful chemical compounds is necessary. This includes using an effective ventilation system, equipping appropriate personal protective equipment, and conducting regular monitoring of the working environment to ensure worker safety.
On a basic level, if working in an industrial environment, adhering to safety standards and limiting exposure to Vinyl acetylene 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 health effects of Vinyl acetylene (1-Buten-3-yne) on workers
Minimizing the health effects of this compound on workers requires a combination of technical, administrative, and personal measures. First, it is necessary to improve the ventilation system in the factory to limit the concentration of chemical vapors in the air. Local exhaust ventilation systems should be installed at locations with a high risk of toxic gas generation to control its spread.
In addition, businesses need to conduct regular workplace environment monitoring to measure chemical concentrations and ensure they do not exceed safe limits. Applying occupational safety standards, including proper equipment operation and maintenance procedures, helps minimize the risk of leaks or unintentional exposure.
Workers must be fully equipped with personal protective equipment such as chemical-resistant masks, gloves, safety glasses, and specialized clothing when working in high-risk environments. Furthermore, training and education on chemical safety play a crucial role in raising awareness and response skills in case of an incident.
Occupational safety training: Workers need to be trained and educated on 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 occupational environment monitoring in factories and enterprises, collect and analyze factors harmful to workers, thereby adjusting to reduce the level of hazard to prevent occupational diseases for them.
