Precautions

Thiourea dioxide is the same as general chemicals. If you pay attention to avoid heat, moisture and external pollution, you can maintain long-term stability. Please observe the following items during operation:

Store in a dry and clean warehouse with good ventilation and room temperature below 30℃. Keep away from fire, heat sources and direct sunlight. Pay attention to moisture and rain. Keep the container sealed, and pay attention to the integrity of the label. Handle with care when loading and unloading to prevent damage to the packaging and the container, and pay attention to keeping the pressure discharge of the container normal. Not suitable for transportation on rainy days. It should be equally divided with flammable or combustible materials, 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, etc. The reaction will accelerate if water is mixed.

Thiourea dioxide is a unstable compound to heat. When it comes into contact with heat sources such as steam pipes, heating appliances, welding sparks, and other electric heaters, it produces an irritating odor and decomposes. Or heat conduction caused by friction and mixing are more dangerous, so please avoid it. Once decomposed, the heat generated promotes decomposition.

Thiourea dioxide cannot be returned to the original bag once it has been removed from the bag or leaked. Because it is contaminated by stolen goods, rust, water and other pollutants, it is accelerated to decompose. The leaked things are dissolved in a lot of water and thrown away.

Wear rubber gloves and masks when contacting thiourea dioxide. Although it is not toxic to the body, a small number of people with allergies are prone to eczema. After contact, pay attention to the skin exposed to the skin and wash thoroughly with water.

When handling or storing thiourea dioxide products or aqueous solutions, plastic utensils are most suitable. Stainless steel, porcelain, and glass utensils can also be used. When the aqueous solution is left, thiourea dioxide will slowly decompose to generate sulfuric acid, and the pH value will decrease. Please be careful to avoid the use of iron, copper, aluminum containers.
