Safety Data Sheet (SDS) for sodium hydrosulfide
Sodium hydrosulfide, with the chemical formula NaHS, is an important chemical raw material and reagent. Due to its specific chemical properties, strict compliance with safety regulations is required during use and handling. This document provides a comprehensive and clear SDS for sodium hydrosulfide, covering key information such as physical and chemical properties, hazard identification, emergency measures, handling and storage, and waste disposal to ensure personnel safety and environmental compliance.
1. Chemical and Company Identification
Chemical Name: Sodium hydrosulfide
CAS Number: 16721-80-5
Molecular Formula: NaHS
Molecular Weight: 56.06
2. Hazards Identification
Main Hazards:
Health Hazards: Highly corrosive and irritating to the skin, eyes, and respiratory system. Decomposes in contact with acids or humid air to release hydrogen sulfide (H₂S), a highly toxic gas with a rotten-egg odor. At high concentrations, it can cause olfactory fatigue, leading to acute poisoning and even death from respiratory paralysis.
Environmental Hazards: Toxic to aquatic organisms.
GHS Pictograms: Corrosive, Acute Toxicity, Environmental Hazard
Signal Word: Danger
Hazard Statements: Causes severe skin burns and eye damage. Fatal if inhaled. Very toxic to aquatic life.
