(1) Hazard Overview: Terephthalic acid is flammable and poses a risk of combustion when exposed to high heat, open flames, or contact with oxidants. Its dust may cause irritation to the eyes and respiratory system.
(2) First aid measures: In case of accidental contact with eyes or skin, rinse immediately with plenty of water and seek medical assistance. When ingested by mistake, rinse your mouth immediately and seek medical attention.
(3) Fire fighting measures: In case of fire, use dry powder, foam or carbon dioxide extinguisher to extinguish the fire. Do not spray water directly to prevent the fire from spreading.
(4) Personal protection and environmental protection: When using terephthalic acid, appropriate personal protective equipment should be worn to ensure good ventilation in the work environment. Waste terephthalic acid should be properly disposed of in accordance with local environmental regulations to avoid pollution to the environment.
