EXPOSURE


 •INHALATION
Ventilation.
Fresh air, rest.
 •SKIN Redness.
Protective gloves.
Rinse skin with plenty of water or shower.
 •EYES Redness. Pain.
Safety goggles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
 •INGESTION
Do not eat, drink, or smoke during work.
Rinse mouth.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place. (Extra personal protection: filter type B.)
Separated from acids, bases , oxidants . Cool. Dry. Keep in a well-ventilated room.
