First-aid measures
Description of first aid measures
First aid personnel should pay attention to their own safety. If the patient is likely to become unconscious, place and transport in stable sideways position (recovery position). Immediately remove contaminated clothing.
If inhaled:
Keep patient calm, remove to fresh air, seek medical attention. Immediately administer a corticosteroid from a controlled/metered dose inhaler.
On skin contact:
Immediately wash thoroughly with plenty of water, apply sterile dressings, consult a skin specialist.
On contact with eyes:
Immediately wash affected eyes for at least 15 minutes under running water with eyelids held open, consult an eye specialist.
On ingestion:
Do not induce vomiting. Immediately rinse mouth and then drink 200-300 ml of water, seek medical attention.
Most important symptoms and effects, both acute and delayed
Symptoms: The most important known symptoms and effects are described in the labelling (see section 2 of SDS) and/or in section 11 of SDS.
Indication of any immediate medical attention and special treatment needed
Treatment: Treat according to symptoms (decontamination, vital functions), no known specific antidote, administer corticosteroid dose aerosol to prevent pulmonary odema. Medical monitoring for at least 24-48 hours.

Further information on storage conditions: Protect from direct sunlight. Protect against heat. Keep only in the original container. Keep container tightly closed and dry; store in a cool place. Frequently check condition of drums (increase in pressure, bulging, rust). Product has to be immediately consumed or disposed of, if signs of pressure increase or bulging are being detected at a drum.

Supplementary note: The specifications are based on tests, literature data and information of glove manufacturers or are derived from similar substances by analogy.

Body protection:
Body protection must be chosen based on level of activity and exposure., full protection suit with breathing-air supply (f.e. according to EN 943)
General safety and hygiene measures
Avoid contact with the skin, eyes and clothing. Do not breathe vapour/spray. The substance was registered as a transported isolated intermediate. The manufacturer/importer has received the confirmation by the user that the substance is used under strictly controlled conditions in accordance with art. 18 of the REACH regulation (EC) No 1907/2006. When using, do not eat, drink or smoke. Hands and/or face should be washed before breaks and at the end of the shift. Gloves must be inspected regularly and prior to each use. Replace if necessary (e.g. pinhole leaks). Take off immediately all contaminated clothing. Wash contaminated clothing before reuse. Store work clothing separately.

Stability and reactivity
Reactivity
Corrosion to metals:
Corrodes metals in the presence of water.
Reactions with water/air: Reaction with: air
Flammable gases: no
Reaction with: water
Flammable gases: no

Chemical stability
Even when products are stored appropriately a slowly decomposition reaction takes place. If the storage conditions and duration are taken into account, no hazard is caused by the product.
Possibility of hazardous reactions
At elevated temperatures gas forming exothermic decomposition reaction may occur. The formation of gaseous decomposition products builds up pressure in tightly closed containers if the product is greatly overheated. Evolution of corrosive gases/vapours. Reacts with water and basic components to generate heat. Reacts with activated carbon. Reacts with alkalies and metals. Reacts with alcohols, amines, aqueous acids and alkalies. Reacts with water and moisture, with formation of hydrogen chloride. Partly very violent reactions with bases and numerous organic classes of substances such as alcohols and amines.
