Section 3 - Hazards Identification

Appearance: APHA: 20 max clear liquid. Flash Point: 43 deg C.
Danger! Harmful to aquatic organisms; may cause long-term adverse effects in the aquatic environment. Causes burns by all exposure routes. Harmful if swallowed, inhaled, or absorbed through the skin. Flammable liquid and vapor. Oxidizer. Contact with other material may cause fire. May cause sensitization by skin contact.
Target Organs: Respiratory system, gastrointestinal system, eyes, skin.


Potential Health Effects
Eye: Causes eye burns. May cause eye injury.
Skin: Harmful if absorbed through the skin. Causes skin burns. May cause sensitization by skin contact.
Ingestion: Harmful if swallowed. Causes gastrointestinal tract burns.

Section 4 - First Aid Measures

Eyes: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid imme diately.
Skin: Get medical aid immediately. Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.
Ingestion: Do not induce vomiting. Get medical aid immediately. Call a poison control center.

Section 6 - Accidental Release Measures

General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks: Absorb spill with inert material (e.g. vermiculite, sand or earth), then place in suitable container. Wear a self contained breathing apparatus and appropriate personal protection. (See Exposure Controls, Personal Protection section). Remove all sources of ignition. Use a spark-proof tool. Do not use combustible materials such as paper towels to clean up spill. Keep combustibles (wood, paper, oil, etc.,) away from spilled material. Do not let this chemical enter the environment.

Section 7 - Handling and Storage

Handling: Use spark-proof tools and explosion proof equipment. Do not get in eyes, on skin, or on clothing. Keep away from heat, sparks and flame. Avoid contact with clothing and other combustible materials. Do not ingest or inhale. Use only in a chemical fume hood.
Storage: Keep away from sources of ignition. Do not store near combustible materials. Store in a tightly closed container. Store in a dry area. Keep refrigerated. (Store below 4癈/39癋.) Store protected from light.

Section 8 - Exposure Controls, Personal Protection

Engineering Controls: Use explosion-proof ventilation equipment. Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Use only under a chemical fume hood.
