Safety & GHS Classification

GHS03GHS05Irritant

H271: May cause fire or explosion; strong oxidizer
H302: Harmful if swallowed
H314: Causes severe skin burns and eye damage
H335: May cause respiratory irritation
H410: Very toxic to aquatic life with long lasting effects

Storage: Store in cool, dry place away from combustible materials. Strong oxidizer — contact with organic materials can cause fire. NEVER mix with acids (produces explosive chlorine dioxide gas).
