(1) Hazard Overview: Phthalic anhydride is irritating to the skin, eyes, and respiratory system, and long-term exposure may lead to chronic poisoning. In addition, it also has flammability and may cause a fire when exposed to open flames or high temperatures.
(2) Operation precautions: Operators must undergo specialized training and strictly follow the operating procedures. Wear personal protective equipment such as protective clothing, goggles, and gas masks. Ensure good ventilation in the operating environment and regularly monitor the concentration of TMA in the air. Avoid contact with skin and eyes. If accidentally comes into contact with eyes or skin, immediately rinse with plenty of water and seek medical examination. After use, thoroughly clean the body and change clothes. Regularly undergo physical examinations and seek medical attention promptly if any abnormal symptoms are detected. When storing, it should be kept away from fire and heat sources, and explosion-proof lighting and ventilation facilities should be used. Equip corresponding types and quantities of fire-fighting equipment and emergency response equipment for leaks.
