1. Sodium tetrafluoroborate is used as a flux in the soldering and brazing of aluminum and other metals in metallurgy.
2. Sodium tetrafluoroborate serves as a component in electroplating baths for tin, lead, and other metal plating.
3. Sodium tetrafluoroborate is employed as a reagent in organic synthesis, including the Schiemann reaction for preparing aryl fluorides from diazonium salts.
4. Sodium tetrafluoroborate is also used in the production of other fluoroborates, in metal surface treatment, and as a laboratory reagent.

1. Store sodium tetrafluoroborate in a tightly sealed container to protect sodium tetrafluoroborate from moisture, air, and contamination.
2. Keep sodium tetrafluoroborate in a cool, dry, and well-ventilated area, away from heat sources and direct sunlight.
3. Avoid contact between sodium tetrafluoroborate and strong acids or strong bases, which may release hazardous hydrogen fluoride.
4. Keep the container clearly labeled and stored in a secure location, out of reach of children and incompatible materials.

1. Sodium tetrafluoroborate may cause irritation to the eyes, skin, and respiratory tract upon direct contact or inhalation of its dust.
2. Sodium tetrafluoroborate may be harmful if swallowed, and on heating or contact with strong acids, sodium tetrafluoroborate may release toxic hydrogen fluoride fumes.
3. Chronic or prolonged exposure to fluoride compounds such as sodium tetrafluoroborate may affect bones and teeth.
4. Sodium tetrafluoroborate may be harmful to aquatic life if released into the environment.

1. Sodium tetrafluoroborate is not classified as a known carcinogen, but sodium tetrafluoroborate is not safe to handle without precautions.
2. Sodium tetrafluoroborate poses low risk during short, well-controlled use when proper protective measures are applied.
3. Safe handling of sodium tetrafluoroborate requires good ventilation, protective gloves, goggles, and avoidance of dust inhalation and ingestion.
4. In summary, sodium tetrafluoroborate is manageable under controlled conditions with proper protective equipment and environmental controls.
