EXPOSURE


 •INHALATION Cough.
Avoid inhalation of dust.
Fresh air, rest.
 •SKIN

Rinse and then wash skin with water and soap.
 •EYES Redness.
Safety goggles .
Rinse with plenty of water (remove contact lenses if easily possible).
 •INGESTION
Do not eat, drink, or smoke during work.
Rinse mouth.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place.
Separated from strong oxidants, strong bases and halogens .

May be harmful if swallowed
Harmful to aquatic life
