Hazards and Protection.
Storage
Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.
Handling
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.

Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Small spills/leaks
Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers.
Stability
No data.
Incompatibilities
Reaction with chlorine yields explosive chlorine dioxide gas Reaction with ammonia produces ammonium chlorite, which is shock-sensitive.

Fire.
Fire fighting
Flood with water. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible.
Fire potential
These substances will accelerate burning when involved in a fire.
Hazards
May decompose explosively when heated or involved in a fire. May explode from heat or contamination. Some will react explosively with hydrocarbons (fuels). May ignite combustibles (wood, paper, oil, clothing, etc.). Containers may explode when heated. Runoff may create fire or explosion hazard.
Combustion products
Fire may produce irritating, corrosive and/or toxic gases.
