STORAGE & HANDLING
Store in tightly closed containers in a cool, dry, well-ventilated area. Propylene glycol is hygroscopic and can absorb moisture from the atmosphere; containers should therefore remain sealed when not in use.
Avoid contamination with incompatible materials. Consult the applicable Miles® Safety Data Sheet (SDS) before handling, storing, or using this product.
