Storage & Handling
- Recommended Storage
- Store in a segregated, approved flammables area in tightly closed original containers, cool, dry, well-ventilated and out of direct sunlight, preferably sprinkler-protected. Keep away from oxidizing materials and strong acids. Store locked up. Ground and bond containers when transferring.Adjudicated
- Handling Precautions
- Eliminate ignition sources. Use chemical-resistant nitrile or PVA gloves. Bond and ground all transfer equipment. Vapors heavier than air — control ventilation accordingly.Class-level guidance — not product-specific; the SDS controls.
- Incompatibilities
- Strong oxidizing agents (including nitric acid); strong acids, including acetic acid; halogens.Adjudicated
- Shelf Life
- Consult Technical Services for product-specific shelf life
