Sodium nitrite should be stored in a cool, dry place, away from direct sunlight and sources of heat. It is best kept in airtight containers made of inert materials such as glass or polyethylene to prevent contamination and moisture absorption. Due to its corrosive nature, it is important to handle it with appropriate personal protective equipment, including gloves, goggles, and a lab coat. Avoid contact with skin, eyes, and respiratory system to prevent irritation. In case of spillage, neutralize with an appropriate chemical and clean up thoroughly. Proper labeling and storage in designated chemical cabinets are essential to ensure safety and compliance with laboratory protocols.
