Precautions

Store in a dry, clean, well-ventilated warehouse with a room temperature below 30°C. Keep away from fire, heat and direct sunlight. Pay attention to moisture and rain. Keep containers tightly sealed and labels intact. When handling, load and unload with care to prevent damage to packaging and containers, and pay attention to maintaining normal pressure relief in the container. It is not suitable to transport on rainy days. It should be divided equally with flammable or combustible substances, reducing agents, sulfur and phosphorus.
Because thiourea dioxide is a reducing agent, avoid contact with oxidants such as chlorine-based bleach, percarbonate soda, perborate soda, persulfate and other substances. If it is mixed with water, the reaction will be accelerated.
