First Aid Measures

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.
Eyes
In case of contact, immediately flush eyes with copious amounts of water for at least 15 minutes.

Handling and Storage

Storage
Keep tightly closed. Store in a cool dry place.

Exposure Controls/Personal Protection

Personal Protection
Chemical safety goggles, chemically resistant gloves and protective clothing.
Respirators
Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU). Respiratory protection is not required. Where protection is desired, use multi-purpose combination (US) or type ABEK (EN 14387) respirator cartridges.
Exposure Effects
May cause irritation of the eyes, skin and mucous membranes.
