Storage Method and Emergency Response Procedure for Methylacrylate Leakage

Methylacrylate is an organic compound with the molecular formula C4H6O2. It is a colorless and transparent liquid with a pungent smell. It is slightly soluble in water and easily soluble in ethanol, ether, acetone, and benzene. In the preliminary list of carcinogens released by the International Agency for Research on Cancer of the World Health Organization on October 27, 2017, methylacrylate was listed in category 3.

Storage method of Methylacrylate

Methylacrylate is prone to polymerization during storage. Light, heat and peroxides can accelerate its polymerization. Pure monomers do not polymerize below 10℃. Usually, 0.1% hydroquinone monomethyl ether is added as an inhibitor. Store in a cool, ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 37℃. The packaging must be sealed and not exposed to air. It should be stored separately from oxidants, acids, and alkalis and should not be stored for long periods or in large quantities. Use explosion-proof lighting and ventilation equipment. Avoid using mechanical equipment and tools that are prone to sparks. The storage area should be equipped with emergency handling equipment and suitable containment materials. Pack in galvanized iron drums. Store separately to prevent direct sunlight, and the storage temperature should be kept lower than 21℃. In long-term storage and transportation, inhibitors should be added. Pay attention to fire prevention. Store and transport according to the regulations for flammable goods.

Emergency treatment in case of Methylacrylate leak

Quickly evacuate personnel from the contaminated area to a safe area and isolate strict entry and exit. Cut off the fire source. It is recommended that emergency personnel wear self-contained positive-pressure breathing apparatus and wear firefighting protective clothing. Cut off the leakage source as much as possible to prevent it from entering restricted spaces such as sewers and drainage ditches. For small amounts of leaked chemical compound Methylacrylate, absorb with activated carbon or other inert materials. It can also be washed with plenty of water and the washing water can be diluted and discharged into the wastewater system. For large amounts of leakage, construct a dike or dig a pit for containment; cover with foam to reduce vapor hazards. Spray water in a mist to cool and dilute the vapor, protecting on-site personnel, and diluting the leakage into non-flammable substances. Use an explosion-proof pump to transfer to a tank truck or dedicated collector for recovery or disposal at a waste disposal site.

First aid measures for Methylacrylate exposure

Skin contact: Immediately remove contaminated clothing and thoroughly wash the skin with soap and water. Seek medical attention.
Eye contact: Lift eyelids immediately and rinse thoroughly with plenty of running water or saline for at least 15 minutes. Seek medical attention.
Inhalation: Quickly move away from the scene to fresh air. Keep the respiratory tract unobstructed. If breathing is difficult, administer oxygen. If breathing stops, perform artificial respiration immediately. Seek medical attention.
Ingestion: Rinse mouth with water and give milk or egg white to the person who has ingested it. Seek medical attention.
Firefighting method: Fire extinguishing agent: anti-solvent foam, carbon dioxide, dry powder, sand. Water is ineffective in extinguishing the fire, but it can be used to keep the container cool in the fire. Firefighters must wear full-body fire and poison prevention clothing. In case of a large fire, firefighters must operate in a protective shelter.
