First Aid Measures

Ingestion
If swallowed, wash out mouth with water provided person is conscious. Call a physician.
Ingestion
Toxic if swallowed.
Inhalation
May be harmful if inhaled.
Inhalation
If inhaled, remove to fresh air. If not breathing give artificial respiration. If breathing is difficult, give oxygen.
Skin
May be harmful if absorbed through the skin.
Skin
In case of contact, immediately wash skin with soap and copious amounts of water.
Skin
Remove and isolate contaminated clothing and shoes. Immediately flush with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin.
Eyes
See Inhalation.
Eyes
Assure adequate flushing of the eyes by separating the eyelids with fingers.
Eyes
In case of contact, immediately flush eyes with copious amounts of water for at least 15 minutes.
