First Aid Measures

Ingestion

Seek medical assistance.

Inhalation

Move victim to fresh air. Apply artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes.

Skin

Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush with running water for at least 20 minutes. Wash skin with soap and water.

Eyes

In case of contact with substance, immediately flush with running water for at least 20 minutes.

Keep tightly closed. Keep away from heat and open flame. Store in a cool dry place.

Hazards Identification

Inhalation

May be fatal. May cause irritatior or burns. Vapors may cause dizziness or suffocation.

Skin

See inhalation.

Eyes

See inhalation.

Ingestion

Exposure Controls/Personal Protection

Personal Protection

Compatible chemical-resistant gloves. Chemical safety goggles.

Respirators

Wear positive pressure self-contained breathing apparatus (SCBA).

Exposure Effects

Toxic. Toxic by inhalation, in contact with skin and if swallowed. Irritating to eyes, respiratory system and skin.

Fire Fighting Measures

Flash Point

54

Fire Fighting

Extinguish using Carbon dioxide, dry chemical powder, or appropriate foam. Water spray. Wear self-contained breathing apparatus and protective clothing to prevent contact with skin and eyes.

Fire Potential

HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames.

Accidental Release Measures

Small spills/leaks

Make no contact with the spilled material. Fully encapsulating, vapor protective clothing should be worn for spills and leaks with no fire. ELIMINATE all ignition sources and ground all equipment. Stop leak if you can do it without risk. A vapor suppressing foam may be used to reduce vapors. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. Use clean non-sparking tools to collect absorbed material.
