What Are The Hazards And Safety Precautions Associated With Handling Sodium Hydrosulfite?

Sodium hydrosulfite is a white crystalline powder commonly used as a reducing agent in various industrial applications, such as textile and paper industries. However, it can pose several hazards if not handled properly.

Firstly, sodium hydrosulfite is highly reactive with water, acids, and oxidizing agents, which can result in the release of flammable and toxic gases, including sulfur dioxide. Therefore, it should be stored in a cool, dry, and well-ventilated area away from any incompatible materials.

Secondly, sodium hydrosulfite can cause severe skin and eye irritation upon contact and inhalation of its dust or fumes. Hence, personal protective equipment (PPE), including gloves, safety goggles, and respiratory protection, must be worn when handling this compound.

Thirdly, sodium hydrosulfite can decompose at high temperatures, producing hydrogen sulfide gas, which is highly toxic and can cause serious health effects. Therefore, it is crucial to avoid exposing this compound to heat sources, direct sunlight, or open flames.

In conclusion, proper handling of sodium hydrosulfite requires good ventilation, appropriate storage conditions, and the use of PPE. It is also essential to avoid any contact with incompatible materials and prevent exposure to high temperatures.
