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 tightly closed. Store in a cool dry place.

Hazards Identification

Inhalation
Material is irritating to mucous membranes and upper respiratory tract.
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). Where risk assessment shows air-purifying respirators are appropriate use a full-face respirator with multi-purpose combination (US) or type ABEK (EN 14387) respirator cartridges as a backup to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air respirator.
Exposure Effects
Causes eye and skin irritation. May be harmful by inhalation, ingestion, or skin absorption.

Fire Fighting Measures

Flash Point
113
Fire Fighting
Extinguish with water spray, carbon dioxide, dry chemical powder or appropriate foam. Wear self-contained breathing apparatus and protective clothing to prevent contact with skin and eyes.

Accidental Release Measures

Small spills/leaks
Sweep up, place in a bag and hold for waste disposal. Avoid raising dust. Ventilate area and wash spill site after material pickup is complete.

Stability and Reactivity

Stability
Stable at normal temperatures and pressures.
Incompatibilities
Strong oxidizing agents.
Decomposition
Oxides of carbon.
