Hazards Identification

Ingestion

May cause toxic effects.

Inhalation

Vapors may cause dizziness or suffocation. May cause toxic effects.

Skin

Contact with substance may cause severe burns.

Exposure Controls/Personal Protection

Personal Protection

Wear appropriate protective gloves, clothing and goggles.

Respirators

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

Fire Fighting Measures

Flash Point

19

Fire Fighting

Small Fires: Dry chemical, carbon dioxide, water spray or alcohol-resistant foam. Large Fires: Water spray, fog or alcohol-resistant foam.

Fire Potential

Flammable/combustible material. May be 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.
