04 · Handling and storage
Storing and handling Dichloro-1,3,5-triazinetrione
Storage conditions
Protect against phys damage. Store in cool, dry, well-ventilated place away from flammable liq, combustible materials, and oxidizable materials. Drums may rupture if contents are exposed to heat or become contaminated or wet. Drums should be palletized to prevent wetting from floor washings or drainage. Avoid prolonged storage in unventilated areas at summer temperatures.

Incompatible materials
Not combustible, but contact with most foreign materials, organic matter or easily chlorinated or oxidized materials may result in fire since this substance is a highly reactive oxidizing and chlorinating agent. Contact with ammonia, ammonium salts, urea or similar compounds which contain nitrogen may form nitrogen trichloride, a highly explosive compound.
