Administrative data
First-aid measures
Helpers should ensure their own protection.
If the patient is unconscious, must be turned and kept on his/her side during transportation.
Inhalation
Remove victim to fresh air and keep at rest in a position comfortable for breathing.
If appropriate, give artificial respiration or oxygen.
Inhale or give immediate treatment using corticosteroids dosing spray.
Get medical advice/attention.
Symptoms can be delayed.
Skin contact
Rinse continuously with water for several minutes.
Sterile bandage.
Get medical advice/attention.
Eye contact
IF IN EYES: Rinse continuously with water for several minutes. Get medical advice/attention.
Ingestion
Rinse mouth.
If the patient is conscious, give plenty of water (2 - 4 glasses).
Do NOT induce vomiting.
Never give anything by mouth to an unconscious person.
Get immediate medical advice/attention.
Indication of any immediate medical attention and special treatment needed
Treat symptomatically.
Fire-fighting measures
Water spray
Carbon dioxide
Alcohol resistant foam
Dry Chemical
Unsuitable extinguishing media: Do not use powerful water injection.
Special hazards arising from the substance or mixture
May emit toxic fumes of oxides of carbon and nitrogen during heating or fire.
May emit toxic fumes of ammonia during heating.
Vapour may form explosive mixtures with air.
Advice for fire-fighters
Special protective equipment for fire-fighters: Isolating breathing apparatus eg. compressed breathing apparatus and protective clothing.
Other instructions
Cool fire exposed containers with water jet.
Extinguishing water must not be discharged into waterways, sewers, soil.
Accidental release measures
Use personal protective equipment as required.
Environmental precautions
Absorb with inert material (eg sand, silica gel, acid sorbent, universal sorbent).
Do not put into water system, drain or soil.
Collect up into tightly sealable containers for disposal.
Vapours can be bound e.g. with water spray.
Methods and material for containment and cleaning up
Neutralize with hydrochloric or sulfuric acids.
Disposal: see 'Disposal considerations'.
Handling and storage
This substance is handled under Strictly Controlled Conditions in accordance with REACH regulation Article 18(4) for transported isolated intermediates. Site documentation to support safe handling arrangements including the selection of engineering, administrative and personal protective equipment controls in accordance with risk-based management systems is available at the manufacturing site.
If exposure is possible:
Handle in well-ventilated space.
Avoid breathing dust/fume/gas/mist/vapours/spray.
Keep away from heat/sparks/open flames/hot surfaces - No smoking.
Do not eat, drink or smoke at workplace. Wash hands after working with substance.
WARNING: The vapour is heavier than the air.
Take precautionary measures against static discharge.
Conditions for safe storage, including any incompatibilities
Keep away from heat/sparks/open flames/hot surfaces - No smoking.
Store in a well ventilated place. Keep cool.
Store in a dry place. Store in a closed container.
Protect from sunlight.
Keep away from acid-generating agents.
Store separately from food products, animal feedstuff and beverages.
Keep away from acids.
Storage time: 24 months.

Disposal considerations
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
