Ethyl methacrylate

Precautions for storage Usually, the product is added with a polymerization inhibitor. Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Keep away from light. Storage temperature should not exceed 37°C. The packaging is required to be airtight and not in contact with air. It should be stored separately from oxidants, acids, and alkalis, and should not be mixed. It should not be stored in large quantities or stored for a long time. Explosion-proof lighting and ventilation facilities are adopted. Prohibit the use of mechanical equipment and tools that are prone to sparks. The storage area should be equipped with leakage emergency treatment equipment and suitable containment materials.

1. The toxicity of this product is similar to that of methyl methacrylate, and the oral LD50 is 15mL/kg. The protection requirements are the same as methyl methacrylate. See methyl methacrylate.
