SODIUM ACETATE — STORAGE & HANDLING GUIDELINES
Storage:
Store in a cool, dry, and well-ventilated area away from moisture and direct sunlight.
Keep containers tightly closed when not in use to prevent clumping or contamination.
Avoid storage near strong oxidizing agents (e.g., nitric acid, hydrogen peroxide) to prevent unwanted chemical reactions.
Recommended storage temperature: Below 40°C.
Use HDPE bags or airtight containers with inner liners for long-term stability.
Stack bags properly on pallets, away from walls and floors to prevent moisture absorption.
Handling:
Handle with clean, dry tools and wear appropriate protective gear (gloves, goggles, mask).
Avoid generating or inhaling dust — ensure adequate ventilation in the working area.
Prevent contact with eyes, skin, or clothing. In case of contact, rinse thoroughly with water.
Do not eat, drink, or smoke while handling the material.
Wash hands and exposed skin thoroughly after use.
Safety Precautions:
Although Sodium Acetate is non-toxic and non-corrosive, good industrial hygiene practices should be followed.
In case of spillage, sweep up the material carefully and place it in a suitable container for reuse or disposal.
Dispose of waste in accordance with local environmental regulations.
Shelf Life:
Stable for up to 24 months under recommended storage conditions.
Avoid exposure to humidity to maintain purity and flow characteristics.
