Health.
Exposure effects
Harmful if swallowed, inhaled, or absorbed through skin. May cause cyanosis (blue-gray coloring of skin and lips caused by lack of oxygen).
   Inhalation
Material is irritating to mucous membranes and upper respiratory tract.
   Skin
Causes irritation.
   Eyes
Causes irritation.

First aid
 
   Ingestion
If swallowed, wash out mouth with water provided person is conscious. Call a physician.
   Inhalation
If inhaled, remove to fresh air. If not breathing give artificial respiration. If breathing is difficult, give oxygen.
   Skin
In case of contact, immediately wash skin with soap and copious amounts of water. Remove contaminated clothing and shoes. Call a physician.
   Eyes
In case of contact with eyes, flush with copious amounts of water for at least 15 minutes. Assure adequate flushing by separating the eyelids with fingers. Call a physician.
