Safety data sheet for sodium hydroxide providing hazard information, handling, storage, and emergency measures.
This document presents the chemical identification of sodium hydroxide (NaOH) and its hazardous properties, including strong corrosivity, health hazards, and environmental impact. It details the composition, purity (≥98.0%), and regulatory identifiers such as CAS No. 1310-73-2.
The sheet also outlines first‑aid measures, fire‑fighting instructions, accidental release procedures, safe handling and storage practices, personal protective equipment requirements, physical‑chemical properties, stability, transport guidelines, and disposal methods. This manual is written in Chinese.
