Maleic anhydride

In case of unconsciousness place patient stably in side position for transportation. Provide fresh air.

Symptoms: Lachrymation, burning sensation of nose and throat, bleeding from the nose, weakness, coughing, rhinitis, irritation of respiratory tract and weakness of breathing. Coughing, headache, indisposition, shortness of breath.

Immediately wash with water and soap and rinse thoroughly.

Symptoms: Sensitization possible through skin contact. After prolonged action severe corrosion of skin with poorly healing wounds, burning of skin, strong irritating/corrosive action, extremely corrosive action on skin.

Call a doctor immediately. Remove contact lenses immediately! Rinse opened eye for several minutes under running water.

Symptoms: Lachrymation, burning sensation of eyes, severe damage of the eyes, strong irritation with danger of serious damage to eyes, sensitizing action, visual defects, danger of conjunctivitis.

Call for a doctor immediately. Drink plenty of water.

Symptoms: After swallowing headache, vomiting, abdominal pain.

Alcohol resistant foam, Carbon dioxide, Water, Foam, Extinguishing powder.

Do not use water jet with hot melt: Steam explosion with propagation of material. Do not use extinguishing powder, hot maleic anhydride may thermally decompose or explode because of impurities.

Formation of explosive dust/air-mixtures is possible. Strong heating may cause formation of potentially explosive vapours.

Keep people at a distance and stay on the windward side. Let spilled melt cool and solidify, then take up mechanically.

Do not allow to enter sewers/ surface or ground water. Keep contaminated washing water and dispose of appropriately.

Absorb with liquid-binding material, Let spilled melt cool and solidify, then take up mechanically.

Materials: sand, diatomite, acid binders, universal binders, sawdust

Empty containers must not be used for other products. Contaminated protective equipment should be cleaned before taking it off. Any unavoidable deposit of dust must be completely removed. Prevent formation of aerosols. Protect from humidity. Use additional container if material is transported in glass bottles. Fill only in dedicated and assigned containers. Keep containers tightly sealed.

Store in a dry location, keep away from humidity. Store in a cool location. Use only receptacles specifically permitted for this substance/product.

Contaminated protective equipment should be cleaned before taking it off.

Protect against electrostatic charges. Use explosion-proof apparatus / fittings and spark-proof tools.

Handling of material under inert gas and protected from humidity. Sufficient ventilation is recommended. Check seals on flanges and valves for suitability and corrosion resistance. If necessary inspection intervals should be defined! Handle this material under exclusion of humidity. If possible use this material only in closed systems and devices. In case of open plant systems (sampling devices, filling and discharging, cleansing works etc.) use local exhaust and collecting trays.

Selection of the glove material on consideration of the penetration times, rates of diffusion and the degradation. Information given in the Exposure Scenarios in the annex have to be observed. For the permanent contact gloves made of the following materials are suitable: Do not wear gloves made from the following materials longer than 8 hours: Baypren-Viton. Check for tightness before use. Replace damaged gloves.

Tightly sealed goggles.

Short term filter device: Particle filter. The filter grade (P1 - P3) has to be established depending on work-place related limit values and the actual exposition. Information given in the Exposure Scenarios in the annex have to be observed.

Use only liquid proof and chemical resistant protective suit. Use protective suit with self-contained breathing apparatus.

Waste gases should be led into the atmosphere only via appropriate separators, scrubbers or incinerators. Avoid spillage of product into the environment. If possible use this material only in closed systems and devices. In case of open plant systems (sampling devices, filling and discharging, cleansing works etc.) use local exhaust and collecting trays. Follow emission limit values. Measures in case of unwanted emissions should be established. Measures for prevention of hazards in case of unwanted leakage (LOPC) shall be implemented.

No decomposition if used according to specifications.

see 10.3.

Maleic anhydride reacts with sodium, potassium, ammonia salt solutions and hydroxides with formation of carbon dioxide. Above 150°C MAN decomposes and polymerizes under the influence of small amounts of alkali compounds or amines. Vigorous reaction with strong oxidising agents. Hydrolyses with water forming maleic acid. Reacts violently with water Possible formation of explosive mixtures with air upon strong heating.

Avoid electrostatic charge.

Exposure to humidity. Strong oxidizing agents. Alkali/erthalkali hydroxides, alkali metals, sodium ions, cations. Acids Humidity Bases

Carbon monoxide Carbon monoxide and carbon dioxide In the event of fire: See chapter 5.

Must not be disposed together with household garbage. Do not allow product to reach sewage system. Must be specially treated adhering to official regulations. If possible recovery or recycling.

Empty container completely. Storage in a safe place after emptying.
