TDI should be stored in a cool, dry environment to prevent degradation and maintain its chemical integrity. It is recommended to use sealed containers made of materials that are chemically inert to isocyanate groups, such as stainless steel or glass. Due to its reactive nature, TDI must be kept away from moisture, heat, and incompatible substances like acids or bases. Proper ventilation is essential when handling TDI to minimize exposure to its strong odor. Laboratory personnel should wear appropriate personal protective equipment, including gloves, goggles, and a lab coat, to ensure safe handling. Regular monitoring of storage conditions is necessary to maintain the quality and safety of the material.
