Section 6 - Accidental Release Measures
|
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth),
then place in suitable container. Clean up spills immediately,
observing precautions in the Protective Equipment section.
|
Section 7 - Handling and Storage
|
Handling:
Empty containers retain product residue, (liquid and/or vapor), and
can be dangerous. Keep away from heat, sparks and flame. Do not
pressurize, cut, weld, braze, solder, drill, grind, or expose empty
containers to heat, sparks or open flames.
Storage:
Keep away from heat, sparks, and flame. Flammables-area.
