Handling and StorageBack to Contents
【Storage】

Keep away from heat, sparks, and flame. Keep container closed when not in use. Flammables-area. Storage under a nitrogen blanket has been recommended.
【Handling】

Wash thoroughly after handling. Use only in a well ventilated area. Avoid contact with eyes, skin, and clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Avoid contact with heat, sparks and flame. Avoid ingestion and inhalation. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames.
Hazards IdentificationBack to Contents
【Ingestion】

May cause irritation of the digestive tract.
【Inhalation】

Vapor or mist is irritating to the mucous membranes and upper respiratory tract.
【Skin】

Causes skin irritation.
【Eyes】

Vapors cause eye irritation.
【Hazards】
