NINGBO INNO PHARMCHEM CO.,LTD. is committed to promoting the safe and responsible use of chemicals, and Sodium Hydrosulfide Hydrate (CAS 207683-19-0) is no exception. Due to its corrosive nature and the potential for releasing toxic hydrogen sulfide (H₂S) gas, understanding and implementing proper safety protocols is non-negotiable for anyone working with this compound.

Hazard Identification: Sodium Hydrosulfide Hydrate is classified as a hazardous substance. It is corrosive and can cause severe skin burns and eye damage. The primary inhalation hazard stems from the release of hydrogen sulfide gas, which is toxic and has a characteristic rotten egg odor at low concentrations, but can rapidly cause olfactory fatigue and be fatal at higher concentrations. This makes adequate ventilation and respiratory protection critical.

Personal Protective Equipment (PPE): When handling Sodium Hydrosulfide Hydrate, it is imperative to wear appropriate PPE. This includes chemical-resistant gloves (such as nitrile or neoprene), safety goggles or a face shield to protect the eyes, and protective clothing, including a lab coat or apron. In situations where dust or aerosols might be generated, respiratory protection, such as a respirator with appropriate cartridges, should be used.

Safe Handling Practices: Always handle Sodium Hydrosulfide Hydrate in a well-ventilated area, preferably under a fume hood, to minimize inhalation exposure to H₂S. Avoid contact with skin, eyes, and clothing. Use non-sparking tools when handling the solid form to prevent ignition, as H₂S is flammable. When preparing solutions, add the solid slowly to water, avoiding splashing. Never add water to the solid, as this can cause a vigorous reaction.

Storage Requirements: Sodium Hydrosulfide Hydrate should be stored in tightly sealed, corrosion-resistant containers in a cool, dry, and well-ventilated area. It is crucial to keep it separated from incompatible materials, particularly acids, oxidizing agents, and moisture, which can trigger the release of hazardous H₂S gas. Containers should be clearly labeled with hazard warnings.

Emergency Procedures: In case of skin contact, immediately wash the affected area with plenty of soap and water for at least 15 minutes. For eye contact, flush eyes with copious amounts of water for at least 15 minutes, holding eyelids open, and seek immediate medical attention. If inhaled, move the person to fresh air and seek medical attention if breathing difficulties arise. In the event of a spill, contain the material and neutralize it carefully using an appropriate agent, such as dilute acid (e.g., acetic acid), in a well-ventilated area before disposal.

NINGBO INNO PHARMCHEM CO.,LTD. encourages all users to consult the Safety Data Sheet (SDS) for Sodium Hydrosulfide Hydrate before use. Proper training and adherence to these safety guidelines are essential to ensure a safe working environment.
