Keep victim warm, in a stabilized position and covered.
Do not leave victims unattended.
If the casualty is unconscious: Place the victim in the recovery position.

Inhalation:
Potential for exposure by inhalation if dusts or smoke are generated.
Move victims into fresh air.
With labored breathing: Provide with oxygen. Consult a doctor.
If the casualty is not breathing: Perform mouth-to-mouth resuscitation, notify emergency physician immediately.

Skin contact:
Wash off affected area immediately with plenty of water for at least 15 minutes.
If symptoms persist, consult a physician for treatment.

Eye contact:
With eye held open, thoroughly rinse immediately with plenty of water for at least 10 minutes.
Consult an ophthalmologist immediately if the symptoms persist.

Ingestion:
Rinse mouth.
Immediately give large quantities of water to drink.
Obtain medical attention.

Most important symptoms and effects, both acute and delayed:
Symptoms:
- Daze
- Headache
- Vertigo
- Somnolence (sleepiness)
- Nausea
Health injuries may be delayed.

Hazards:
Very toxic by inhalation.
Toxic if swallowed.

Indication of any immediate medical attention and special treatment needed:
After accidental absorption in the body, the pathology and clinical findings are dependent on the kinetics of the noxious substance (quantity of absorbed substance, the absorption time, and the effectiveness of early elimination measures (first aid)/ excretion - metabolism).
Continue with first aid measures.
Depending on the pathology and clinical findings, patient monitoring and symptomatic treatment are necessary.

Advice for firefighters:
Contaminated extinguishing water must be treated at a suitable disposal plant in accordance with waste management laws.
Water used to extinguish fire should not enter drainage systems, soil or stretches of water.
In case of fire, remove the endangered containers and bring to a safe place, if this can be done safely.
Use water spray to cool unopened containers.
Fire residues should be disposed of in accordance with the regulations.
Pay attention to self-protection.
Keep out unprotected persons.
In case of fire: full protective suit and wear a self contained respiratory apparatus.

Accidental release measures

Personal precautions, protective equipment and emergency procedures:
Keep unauthorized persons away.

Environmental precautions:
Observe regulations on prevention of water pollution (check, dam up, cover up).
Do not allow entrance in sewage water, soil, stretches of water, drainage systems, surface water.
If the product contaminates rivers and lakes or drains inform respective authorities.

Methods and material for containment and cleaning up:
Accidental release measures:
Clean contaminated surface thoroughly.
Pack and label wastes like the pure substance.
Do not detach label from the delivery containers prior to disposal.
Disposal according to local authority regulations.

Handling and storage

Precautions for safe handling:
Decant and handle product in separate areas only, e.g. use glove boxes, cabinets with differential pressure switch etc.
Ensure that apparatus and pipelines are free from leaks.
Do not ventilate into the open.
Dedicated loading/unloading stations required.

Conditions for safe storage, including any incompatibilities:
Advice on protection against fire and explosion:
Normal measures for preventive fire protection.
Ensure there are sufficient retaining facilities for water used to extinguish fire.
Further information: VDI 2263 "Dust fires and dust explosions; dangers, evaluation, preventive measures."

Storage:
Store in the original receptacle, keeping this tightly sealed, under cool and dry conditions.

Further information:
Protect from sunlight, warmth and heat.
In order to ensure due transportation, make certain that stacks are of the correct height, containers are securely fastened so as not to fall off, and labelled according to the regulations.
In the event of internal transportation, already-opened containers are to be kept closed in order to avoid spillage.

Exposure controls / personal protection

Control parameters
Other information:
Contains no substances with occupational exposure limit values.

DNEL/DMEL values:
Remarks: No substance-related safety assessment is necessary / has been conducted for this product.
