6. ACCIDENTAL RELEASE MEASURES Small Spill Absorb liquid on vermiculite, floor absorbent or other absorbent material. Large Spill Persons not wearing protective equipment should be excluded from the area of spill until clean-up has been completed. Decontaminate spilled material by careful application of aqueous ammonium hydroxide or sodium bisulfite solution. Considerable heat and fumes can be liberated by the decontamination reaction.

7. HANDLING AND STORAGE Handling Containers of this material may be hazardous when emptied. Since emptied containers retain product residues (vapor, liquid, and/or solid) , all hazard precautions given in the data sheet must be observed. Storage Product solutions are corrosive to many commonly used materials of construction such as steel, galvanized iron, aluminum, tin and zinc. TK^e solutions can be stored and handled in baked phenolic-lined steel, polyethylene, stainless steel, or reinforced epoxy-plastic equipment. This product freezes at about -17 degrees C (1.4 degrees F)- Therefore, unless the storage tank is inside or underground, heating and insulation may be required. If heating is needed, exposure to high temperatures should be avoided. For short storage times (up to about one month), temperatures of up to 100 degrees F can be tolerated, but the preferred maximum storage temperature is about 80 degrees F.
