The Safety Data Sheet (SDS) of Sodium Hydroxide

Sodium hydroxide (NaOH), commonly known as caustic soda or lye, is an inorganic compound that is widely used across various industries for its strong alkaline properties. This article delves into the importance of the Safety Data Sheet (SDS) associated with sodium hydroxide, providing essential information regarding its hazards, handling practices, and safety measures to ensure safe usage.

Overview of Sodium Hydroxide

Sodium hydroxide is a white, odorless solid that can be encountered in various forms, including flakes, pellets, and solutions. It is highly soluble in water, generating exothermic heat upon dissolution. Due to its strong alkaline nature, sodium hydroxide is widely utilized in applications such as chemical manufacturing, food processing, papermaking, textile production, and water treatment. However, its corrosive nature necessitates the strict adherence to safety protocols.

Understanding the SDS

The Safety Data Sheet (SDS) for sodium hydroxide is a vital resource that provides comprehensive information regarding its properties, potential hazards, safe handling and storage practices, and first aid measures in case of an exposure incident. The SDS is structured in a standardized format consisting of 16 sections, making it easier for users to find relevant information.

1. Identification The first section outlines the chemical's name, synonyms, and uses, along with contact information for the manufacturer or distributor. 2. Hazard Identification This section details the potential hazards associated with sodium hydroxide, including its corrosive properties and the risks it poses to skin, eyes, and respiratory systems.
