Key Warning Information in Safety Data Sheet (SDS) of n-Butyl Acrylate

in the chemical industry, n-butyl acrylate (Butyl Acrylate) is a common chemical, widely used in the production of coatings, adhesives, plastics and other composite materials. As a potentially dangerous chemical, the safety management and protective measures of n-butyl acrylate are very important. This article will combine the key information in the safety data sheet (SDS) of n-butyl acrylate to analyze its potential risks and countermeasures.

1. Physical and chemical properties and potential hazards

n-Butyl acrylate is a colorless, flammable liquid with a slight ether odor. According to SDS, its physicochemical properties include a low flash point (about -7°C), flammable vapors, and sensitivity to light and air. These properties make it a high risk of fire and explosion during storage and transportation. Therefore, it is clearly pointed out in SDS that n-butyl acrylate should be kept away from fire and heat sources and stored in a cool and well-ventilated place.

2. Health hazards and protective measures

The effect of n-butyl acrylate on health is mainly reflected in its volatility. Long-term exposure to high concentrations of n-butyl acrylate vapor may cause acute poisoning symptoms such as headache, dizziness, and nausea. It can also cause irritation to the skin and eyes and even trigger allergic reactions. The SDS emphasizes that operators should wear protective glasses, gloves and respiratory protection to reduce the possibility of direct contact and inhalation.

3. Environmental impact and waste disposal

Butyl acrylate is toxic to the environment and may cause harm to aquatic organisms. It is also highly biodegradable, which means that its impact is limited in the natural environment. The SDS recommends that when disposing of waste, it should be dumped into a special hazardous waste collection container and disposal in accordance with local regulations. Avoid direct discharge of n-butyl acrylate into water or soil.

4. Fire and explosion risk

Due to the flammability of n-butyl acrylate, the risk of fire and explosion is particularly emphasized in the SDS. During storage and transportation, it must be kept away from fire sources, heat sources and oxidants. In the event of a fire, use dry powder fire extinguishers, carbon dioxide fire extinguishers or fire extinguishing equipment suitable for extinguishing Class B fires. It is worth noting that the vapor of n-butyl acrylate may form an explosive mixture in the air, so when used in a confined space, good ventilation must be ensured.

5. First Aid Measures and Accident Handling

In the SDS, first aid measures for n-butyl acrylate are detailed. In case of skin contact, rinse immediately with soap and water for at least 15 minutes; in case of eye contact, rinse immediately with running water for at least 15 minutes and seek medical help; in case of inhalation, immediately remove the patient to fresh air and, if necessary, perform artificial respiration or oxygen therapy. In case of leakage, personnel shall be evacuated quickly and treated with explosion-proof equipment.

6. Safe storage and operation advice

The SDS also provides specific recommendations on the storage and handling of n-butyl acrylate. It should be stored in a cool, well-ventilated place away from fire sources and away from direct sunlight. During operation, ensure that the equipment is sealed to reduce steam leakage. Regularly check the integrity of the storage container to ensure that there is no leakage or damage.

Conclusion

As an important chemical raw material, n-butyl acrylate has high application value in the production process. The potential health hazards, environmental impacts and fire risks also require us to strictly follow the guidelines in the Safety Data Sheet (SDS) during storage, handling and handling. By understanding and implementing these key warning information, we can effectively reduce the probability of accidents and ensure the safety of personnel and the environment.
