Storage & Handling
- Recommended Storage
- Store in tightly closed containers in a cool, well-ventilated place, protected from light and moisture. Keep away from strong bases (caustic soda, caustic potash), reactive metals and metal powders.Adjudicated
- Handling Precautions
- Use standard chemical PPE — splash goggles, gloves, lab coat. Refer to SDS for hazard-specific PPE requirements.Class-level guidance — not product-specific; the SDS controls.
- Incompatibilities
- Strong bases such as caustic soda and caustic potash (can form spontaneously flammable dichloroacetylene); chemically active metals and metal powders (aluminum, magnesium, zinc, barium, alkali metals); strong oxidizing agents; amines.Adjudicated
- Shelf Life
- Consult Technical Services for product-specific shelf life
For full hazard, PPE, and emergency response guidance, refer to the Safety Data Sheet (SDS) for this product. The SDS controls in all cases where guidance differs.
