Sodium Formaldehyde Sulfoxylate, or SFS, is a widely used industrial reducing agent. While it is relatively stable and safe under normal conditions, proper storage and transportation are essential to preserve its chemical integrity and ensure workplace safety.
SFS is typically packaged in moisture-proof bags, fiber drums, or plastic-lined containers. The packaging must be airtight to prevent contact with air and humidity. For bulk shipments, sealed drums or intermediate bulk containers (IBCs) are commonly used. It is important to check that the packaging is intact and free of damage before handling.
SFS should be stored in a cool, dry, and well-ventilated area away from heat sources, open flames, and direct sunlight. The recommended storage temperature is below 25 degrees Celsius. Exposure to high humidity can cause clumping, reduce product activity, and lead to unwanted chemical reactions.
Because SFS is hygroscopic, it can absorb moisture from the air, which may lead to decomposition or a decrease in effectiveness. Always reseal opened packages tightly after use. Storage rooms should be equipped with dehumidifiers or air circulation systems in regions with high ambient humidity.
SFS should not be stored near strong oxidizing agents, acids, or alkaline materials. Contact with incompatible chemicals may cause degradation or produce heat and gases. It is important to separate SFS from other reactive substances in warehouse environments.
During transportation, SFS should be kept in its original sealed packaging. The material should be protected from rain, moisture, and mechanical damage. Transport vehicles should be dry, covered, and free from contamination with incompatible substances.
All containers of SFS must be clearly labeled with product name, batch number, and handling instructions. Transportation should comply with local and international chemical safety regulations. A safety data sheet (SDS) should accompany each shipment to provide emergency guidance if needed.
When stored properly, SFS has a shelf life of 6 to 12 months depending on packaging and storage conditions. It is recommended to use a first-in-first-out (FIFO) system to ensure that older batches are consumed first. Regular quality checks can help confirm product stability.
