Hazard Classification and Standard Operating Procedures for Sodium Hydrosulfide Application

Sodium Hydrosulfide belongs to dangerous chemical with corrosive and irritating properties, and it will produce toxic hydrogen sulfide gas when encountering acid water. Therefore, it is necessary to strictly abide by hazard classification standards and standardized operating procedures in use, storage and handling processes.

 

According to international GHS hazard classification standards, Sodium Hydrosulfide is classified as corrosive substance and environmental hazardous substance. It has strong irritation to human skin, eyes and respiratory tract, and improper operation may cause safety accidents. All operators must receive professional safety training before taking post.

 

In daily operation, staff must wear acid-base resistant gloves, protective goggles, dust masks and protective clothing. The operation site must be equipped with ventilation equipment and emergency flushing devices. Avoid mixing Sodium Hydrosulfide with acidic chemicals to prevent toxic gas overflow.

 

During material feeding and mixing, slow feeding and uniform stirring are required to avoid local excessive concentration and chemical reaction surge. The operation area is strictly prohibited from open fire and high temperature to eliminate potential safety hazards.

 

In case of accidental leakage or contact, emergency treatment shall be carried out in accordance with standard procedures. Leaked materials shall be covered with sand for sealing treatment instead of direct water flushing. Standardized operation can effectively ensure personal safety and production stability.
