Given that TDI (Toluene Diisocyanate) possesses strong irritant properties, exerting significant irritation effects on skin, eyes, and respiratory system, it is imperative to pay close attention to and strictly abide by the following safety precautions when handling this chemical compound. Chief among these measures is to avoid direct contact between TDI and skin or eyes, as any such contact may lead to severe localized irritation reactions. Moreover, inhalation of TDI vapors is also hazardous; hence, during operations, it is essential to wear specialized protective gloves to safeguard hands, don a respirator or dust mask to prevent inhalation of toxic fumes, and equip oneself with safety goggles or a face shield to guard against potential splash entry into the eyes.
Regarding storage, TDI should always be stored in a cool and dry place, aiming to reduce the risk of chemical reactions triggered by excessive temperatures or high humidity levels, as well as to minimize vapor evaporation. In summary, across all aspects involving the manipulation and storage of TDI, there must be an emphasis on reinforced personal protective measures and strict adherence to established safety operating procedures to ensure both personnel health and workplace safety.
