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. 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.

Handling and Storage

Storage
Keep container tightly closed.

Hazards Identification

Ingestion
May be harmful if swallowed.
Inhalation
Material may be irritating to mucous membranes and upper respiratory tract. May be harmful if inhaled.
Skin
May cause skin irritation. May be harmful if absorbed through the skin.
Eyes
May cause irritation.
Hazards
Emits toxic fumes under fire conditions.

Exposure Controls/Personal Protection

Personal Protection
Compatible chemical-resistant gloves. Chemical safety goggles. 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.
