Keep away from sources of ignition. Store in a cool, dry place. Store in a tightly closed container. Keep under a nitrogen blanket. Refrigerator/flammables.

Handling

Wash thoroughly after handling. Wash hands before eating. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Do not allow water to get into the container because of violent reaction. Avoid contact with heat, sparks and flame. Do not get on skin or in eyes. Do not ingest or inhale.

Hazards Identification

Ingestion

Harmful if swallowed. May cause gastrointestinal irritation with nausea, vomiting and diarrhea.

Inhalation

Harmful if inhaled. May cause respiratory tract irritation.

Skin

May cause skin irritation. Harmful if absorbed through the skin.

Eyes

Causes eye irritation.

Hazards

Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion and poison hazard indoors, outdoors or in sewers.
