Safety Precautions

Handle with appropriate PPE including chemical-resistant gloves, splash goggles, and lab coat. Store in a cool, dry place away from direct sunlight in HDPE or glass containers; ensure containers are properly labeled and sealed to prevent contamination. Maintain ventilation during handling to minimize inhalation exposure and avoid contact with bases and oxidizers, which can compromise solution integrity and safety.

Avoid ingestion or contact with skin and eyes. In case of exposure, follow SDS guidance: for eyes, rinse immediately with water for several minutes; for skin, remove contaminated clothing and rinse; in case of inhalation, move to fresh air; if ingested, rinse mouth and seek medical attention. Transport as UN 1805, Phosphoric acid solution, Class 8, PG II. Emergency procedures include eyewash stations and accessible emergency showers in working areas.

Benefits
