Safety Precautions

Sodium hydroxide is a highly corrosive material that must be handled with caution. Avoid direct contact with skin, eyes, and respiratory pathways. Always use chemical-resistant gloves, safety goggles, and full protective clothing. Work in a well-ventilated environment or under a fume hood to prevent inhalation of dust or fumes. Store in a dry, cool, and secure location away from acids, organic materials, and moisture. In case of contact, flush affected areas with plenty of water and seek immediate medical attention.
