Guidance on Safe Use
Administrative data
First-aid measures
INHALATION
Move the exposed person to fresh air at once. Get medical attention.
INGESTION
Wash out mouth with water, provided person is conscious. Get medical attention.
SKIN CONTACT
Remove contaminated clothing and wash skin with soap and plenty of running water. Get medical attention.
EYE CONTACT
Rinse immediately eye with plenty of low pressure water for at least 15 minutes.
Remove any contact lenses. Get medical attention.
Fire-fighting measures
EXTINGUISHING MEDIA
Flashpoint 280 °C
To extinguish fire use water spray, dry powder, carbon dioxide, or foam.
SPECIAL FIRE FIGHTING PROCEDURES
Prevent run-off water from entering the sewer system.
UNUSUAL FIRE & EXPLOSION HAZARDS
Dust may form explosive mixture with air.
SPECIFIC HAZARDS
By fire toxic gases may be formed (Cox, NOx).
PROTECTIVE MEASURES IN FIRE
Self contained breathing apparatus and full protective clothing.
Accidental release measures
PERSONAL PRECAUTIONS
See section on PPE.
ENVIRONMENTAL PRECAUTIONS
Take precautionary measures against discharges into the environment.
SPILL CLEAN UP METHODS
Collect spilled material without creating dust, then place into a suitable closed container for disposal as chemical waste.
Handling and storage
USAGE PRECAUTIONS
Concentrated dust may present an explosion hazard.
Avoid contact with eyes or skin.
Wash thoroughly after handling and before eating, drinking or smoking.
STORAGE PRECAUTIONS
To protect product quality, store in sealed container in a cool place and out of direct sunlight.
Protect against static charge and keep away from source of ignition. Prevent dust formation.

Exposure controls / personal protection
EXPOSURE LIMITS
4 mg/m3 UK EH40/2005 respirable dust
10 mg/m3 UK EH40/2005 total dust
USE LIMITS
None.
PNECs (see also section 12):
aqua-freshwater: 0.112 mg/L
aqua-marine water: 0.0112 mg/L
aqua-intermittent: 1.12 mg/L
sewage treatment plant: 10 mg/L
sediment-freshwater: 400E+005 mg/kg dw
sediment-marine water: 400E+004 mg/kg dw
soil: 9.59 mg/kg dw
Note that the PNELs are much higher than the water solubility (0.00011 nanogram/L) and that consequently the substance will not exhibit any eco toxicity.
DNELs:
The main derived long-term DNELs for systemic effects are:
Workers General population
Oral not relevant 1.67 mg/kg bw/day
Dermal 3.33 mg/kg bw/day 1.67 mg/kg bw/day
Inhalation 2.94 mg/m3/day 0.725 mg/m3/day
