How to deal with long-high-speed high-speed car crashing acrylic leak?

On December 23, the end of a dangerous goods vehicle at the Bincheng Exit (No. 3 port) of the Binshen Expressway in Changshen Expressway led to the leakage of ethyl acrylate. At present, environmental protection personnel are on the scene and fire protection is being processed. The leaked gas was filled with a radius of 10 kilometers. The toll station had started emergency measures. In addition to the duty leaders and the captain's sticking to their posts, the personnel of the station had evacuated. High-speed main line temporarily closed, travel please bypass the national road!

Knowledge extension:

Ethyl acrylate: colorless liquid. Density 0.9405. The refractive index is 1.404. -72 ° C melting point, boiling point 99.8 ° C. Slightly soluble in water, ethanol and ether. Easily polymerized, it can also be copolymerized with other monomers. For the preparation of plastics, resins and other high polymers, can also be used as organic synthesis intermediates. It is prepared by the action of 3-hydroxypropionitrile with ethanol and sulfuric acid, or by the esterification of acrylic acid with ethanol.

Ethyl Acrylate Chemical:
Ethyl acrylate is flammable, its vapor and air can form an explosive mixture, and can cause burning and explosion when exposed to fire or high heat. It can react with oxidants. Its vapour is heavier than air, and it can spread to relatively far places in the lower places. When it encounters fire, it will ignite. It is easy to self-aggregate and the polymerization reaction sharply increases with increasing temperature. When the temperature exceeds 20°C, it can accumulate heat and cause an explosion.

Ethyl acrylate risk:
Ethyl acrylate is irritating to the respiratory tract and pulmonary edema is caused by high concentrations of inhalation. Anesthetic effect. Direct contact with the eyes can cause burns. The skin has obvious irritation and sensitization. Oral stimulation of the oral cavity and digestive tract may cause dizziness, difficulty breathing, and nervousness.
Explosion hazard: This product is flammable, irritating, and allergenic.

Ethyl Acrylate First Aid Measures:
Skin contact: Immediately remove contaminated clothing. Rinse skin thoroughly with soap and water. Get medical attention.
Eye contact: Immediately lift the lid and rinse thoroughly with plenty of running water or saline for at least 15 minutes. Get medical attention.
Inhalation: quickly from the scene to fresh air. Keep the airway open. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration immediately. Get medical attention.
Ingestion: Rinse mouth with water and drink milk or egg white. Get medical attention.

Ethyl Acrylate Fire Control Measures:
Hazardous combustion products: carbon monoxide, carbon dioxide.
Fire extinguishing methods: Firefighters must wear full-body fire protection and anti-virus clothing to extinguish fire in the windward direction. In the event of a fire, firefighters must operate in protective shelters.
Fire extinguishing agents: alcohol-resistant foam, carbon dioxide, dry powder, sand. Extinguishing with water is not effective, but water can be used to keep the containers cool in the fire.

Ethyl acrylate leakage emergency treatment:
Emergency treatment: Rapidly evacuation of personnel from leaking contaminated areas to safe areas, and isolation, strict restrictions on access. Cut off the fire. It is recommended that emergency personnel wear self -contained positive pressure breathing apparatus and wear anti-static overalls. Cut off the leak as much as possible. Prevent restricted space such as sewers and flood drains.
Small leaks: Absorb with activated carbon or other inert materials. It can also be washed with plenty of water, diluted with water, and put into the waste water system.
A lot of leaks: constructing embankments or digging pits for containment. Cover with foam to reduce vapor disasters. The spray-like water cools and dilutes the steam, protects the on-site personnel, and dilutes the leaked material as incombustibles. Use explosion-proof pump to transfer to tanker or special collector, recycle or transport to waste disposal site for disposal.
