Safety Data Sheet (SDS) for Sodium Hydroxide 10%

Introduction

Sodium hydroxide (NaOH), commonly known as caustic soda or lye, is a highly versatile chemical used extensively in various industries. In its 10% solution form, it serves multiple applications, including pH adjustment, cleaning agents, and the production of soaps and detergents. Given its corrosive nature, understanding the safety and handling procedures associated with sodium hydroxide is crucial for ensuring safety in both occupational and laboratory settings.

Chemical Identification

- Chemical Name Sodium Hydroxide - Synonyms Caustic Soda, Lye - CAS Number 1310-73-2 - Molecular Formula NaOH - Concentration 10% Solution

Hazard Identification

Sodium hydroxide is classified as a hazardous substance. It poses significant risks through direct contact, inhalation, and ingestion. The primary hazards associated with the 10% sodium hydroxide solution include

- Corrosive Contact with skin or eyes can cause severe burns and damage. Inhalation of vapors may harm the respiratory tract. - Environmental Hazards Sodium hydroxide can cause harm to aquatic life due to its high alkalinity.

Composition/Information on Ingredients

- Ingredient Sodium Hydroxide - Concentration 10% by weight - Water Content 90% (as the solvent)

First Aid Measures

In case of an accident involving sodium hydroxide, immediate action is crucial

- Inhalation Move the affected person to fresh air immediately. If breathing difficulties develop, seek medical attention. - Skin Contact Rinse the affected area with copious amounts of water for at least 15 minutes. Remove contaminated clothing and seek medical help if irritation persists. - Eye Contact Rinse eyes with water or saline for at least 15 minutes, ensuring that the water flows away from the unaffected eye. Seek immediate medical attention. - Ingestion Do not induce vomiting. Rinse the mouth with water and seek medical assistance immediately.

Fire Fighting Measures

Sodium hydroxide is not flammable; however, it can react exothermically with acids and certain organic materials. In the event of a fire involving sodium hydroxide

- Use appropriate extinguishing agents such as foam, dry chemical powder, or carbon dioxide. - Wear self-contained breathing apparatus and protective clothing to avoid exposure to harmful fumes or vapors.

Handling and Storage

When working with sodium hydroxide solutions, adhere to the following guidelines

- Personal Protective Equipment (PPE) Always wear protective eyewear, gloves, and clothing. Consider face shields and respirators based on the task. - Storage Store in a cool, dry, well-ventilated area, away from incompatible materials such as acids, organic compounds, and metals. Utilize corrosion-resistant containers.

Exposure Control/Personal Protection

To minimize exposure, implement the following control measures

- Engineering Controls Ensure adequate ventilation in workspaces where sodium hydroxide is used. - Personal Hygiene Wash hands thoroughly after handling. Avoid eating, drinking, or smoking in the work area.

Environmental Considerations

Sodium hydroxide can significantly alter the pH of water bodies, impacting both aquatic life and ecosystems. Always follow local regulations regarding the disposal of sodium hydroxide and its solutions.

Conclusion

Sodium hydroxide 10% solution is a powerful and useful chemical, but its handling requires careful consideration of safety protocols. Awareness and adherence to the guidance outlined in the Safety Data Sheet (SDS) can mitigate risks and protect health and safety in environments where sodium hydroxide is used. Always stay informed and prepared when working with this hazardous material.
