Safety Data Sheet (SDS) for 50% Sodium Hydroxide

Introduction Sodium hydroxide, commonly known as lye or caustic soda, is a highly versatile chemical compound with a wide range of industrial and domestic applications. A 50% sodium hydroxide solution is particularly significant due to its efficacy in various processes, including cleaning, chemical manufacturing, and pH adjustment. However, it is critical to handle sodium hydroxide with extreme care, given its highly caustic nature.

Chemical Identification - Chemical Name Sodium Hydroxide - Synonyms Lye, Caustic Soda - CAS Number 1310-73-2 - Molecular Formula NaOH - Concentration 50% w/w in water

Physical and Chemical Properties - Appearance Clear, colorless liquid with a viscous texture. - Odor Odorless. - pH Highly alkaline, typically around 13-14. - Solubility Completely miscible in water; exothermic reaction occurs upon dilution. - Boiling Point Approximately 1400°C (2552°F). - Density About 1.5 g/cm³.

Hazards Identification Sodium hydroxide is classified as a corrosive substance. The following hazards are associated with its use - Skin Contact Can cause severe burns and tissue damage upon contact. - Eye Contact Exposure may result in serious eye damage, potentially leading to blindness. - Inhalation Dust or aerosol can cause respiratory tract irritation and damage to the mucous membranes. - Ingestion Highly toxic; can cause severe injuries to the mouth, throat, and stomach.

First Aid Measures In case of exposure to sodium hydroxide, immediate action is essential - Skin Contact Rinse affected skin with copious amounts of water for at least 15 minutes and seek medical attention. - Eye Contact Rinse eyes immediately with water for at least 15 minutes while holding the eyelids open. Consult a physician immediately. - Inhalation Move the affected individual to an area with fresh air. If symptoms persist, seek medical attention. - Ingestion Do not induce vomiting. Rinse mouth with water and seek medical attention immediately.

Fire Fighting Measures Sodium hydroxide is not flammable; however, it can react with certain metals and generate hydrogen gas, which is flammable. The following measures should be taken during a fire - Use water spray to cool containers. - Extinguish using foam, dry chemical, or carbon dioxide. - Wear self-contained breathing apparatus and protective clothing.

Accidental Release Measures In the event of a spillage, specific procedures should be followed - Evacuate the area and ensure proper ventilation. - Wear appropriate personal protective equipment (PPE). - Contain the spill with inert material (e.g., sand, earth) and collect into compatible containers for disposal. - Neutralize remaining residue with dilute acid before cleaning the area thoroughly.

Handling and Storage To ensure safety when handling sodium hydroxide - Always wear appropriate PPE (gloves, goggles, and protective clothing). - Store in a cool, dry, well-ventilated area away from incompatible materials (e.g., acids, metals). - Ensure containers are tightly sealed and labeled correctly.

Exposure Controls and Personal Protection The following exposure controls are recommended - Use engineering controls such as fume hoods or local exhaust ventilation to minimize inhalation. - Personal Protective Equipment (PPE) should include chemical-resistant gloves, goggles, and face shields. - Ensure that safety showers and eye wash stations are readily accessible in the workplace.

Conclusion While 50% sodium hydroxide is an invaluable chemical for various applications, it poses significant hazards that require diligent safety precautions. Understanding its properties, potential effects, and emergency responses is crucial for ensuring a safe working environment. Always adhere to proper handling and storage guidelines, and prioritize personal safety when working with this hazardous substance.
