|ACUTE HAZARDS / SYMPTOMS||PREVENTION||FIRST AID / FIRE FIGHTING|
|FIRE||Combustible.||NO open flames.||Use water spray, foam, dry powder, carbon dioxide.|
|EXPLOSION||Finely dispersed particles form explosive mixtures in air.||Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent deposition of dust.|
|EXPOSURE||PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!|
|Inhalation||Cough. Sore throat. Wheezing.||Use local exhaust or breathing protection.||Fresh air, rest. Half-upright position. Refer for medical attention.|
|Skin||Redness. Pain.||Protective gloves. Protective clothing.||Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention .|
|Eyes||Redness. Pain.||Wear safety goggles or eye protection in combination with breathing protection.||First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.|
|Ingestion||Abdominal pain.||Do not eat, drink, or smoke during work.||Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Refer for medical attention .|

The symptoms of asthma often do not become manifest until a few hours have passed and they are aggravated by physical effort.
Rest and medical observation are therefore essential.
Anyone who has shown symptoms of asthma due to this substance should avoid all further contact with this substance.
For materials containing more than 0.05% of maleic anhydride the UN number is 2214, hazard class 8, packaging group III and the Transport Emergency Card is TEC (R)-80S2214.
Do NOT take working clothes home.
