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.

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.

Fire Fighting Measures

Flash Point

42

Fire Fighting

For small (incipient) fires, use media such as 'alcohol' foam, dry chemical, or carbon dioxide. For large fires, apply water from as far as possible. Use very large quantities (flooding) of water applied as a mist or spray; solid streams of water may be ineffective. Cool all affected containers with flooding quantities of water. Wear self-contained breathing apparatus and protective clothing to prevent contact with skin and eyes.

Fire Potential

Cumbustible liquid.

Accidental Release Measures

Small spills/leaks

Absorb on sand or vermiculite and place in closed containers for disposal. Ventilate area and wash spill site after material pickup is complete.

Stability and Reactivity

Incompatibilities

Moisture sensitive. Keep away from strong oxidizing agents and strong bases.

Stability

Stable at normal temperatures and pressures.

Decomposition

Carbon monoxide, Carbon dioxide, Hydrogen chloride gas.
