Description of first aid measures
If inhaledFresh air, rest.
Rinse and then wash skin with water and soap.
Rinse with plenty of water (remove contact lenses if easily possible).
Rinse mouth.
Most important symptoms and effects, both acute and delayed
Exposure Routes: inhalation, skin and/or eye contact Symptoms: Irritation eyes, pneumoconiosis Target Organs: Eyes, respiratory system (NIOSH, 2016)
Indication of any immediate medical attention and special treatment needed
Basic treatment: Establish a patent airway. Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if needed. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for pulmonary edema and treat if necessary . Monitor for shock and treat if necessary . Anticipate seizures and treat if necessary . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with normal saline during transport . Do not use emetics. For ingestion, rinse mouth and administer 5 ml/kg up to 200 ml of water for dilution if the patient can swallow, has a strong gag reflex, and does not drool . Cover skin burns with dry sterile dressings after decontamination . Poison A and B
Extinguishing media
In case of fire in the surroundings: all extinguishing agents allowed.
Specific Hazards Arising from the Chemical

Disposal methods
ProductThe material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
