Safety Data Sheet (SDS) for Sodium Hydroxide 10% Solution
1. Identification
Product Name Sodium Hydroxide 10% Solution Chemical Formula NaOH CAS Number 1310-73-2 Manufacturer [Insert Manufacturer Name] Emergency Contact [Insert Emergency Contact Information]
Sodium hydroxide, commonly known as caustic soda or lye, is a highly alkaline compound used in various industrial applications, including pH regulation, cleaning products, and in the manufacturing of soaps and detergents. The 10% solution is a diluted form, which is less concentrated and does not pose the same level of hazards as its stronger counterparts.
2. Hazard Identification
Sodium hydroxide is classified as a hazardous substance by the Occupational Safety and Health Administration (OSHA). Below are the potential hazards associated with this compound
- Corrosive Contact can cause severe skin burns and eye damage. - Toxicity Ingestion or inhalation can be harmful. - Reactivity Reacts violently with acids, releasing heat and potentially creating hazardous conditions.
3. Composition/Information on Ingredients
- Chemical Name Sodium Hydroxide - Concentration 10% - Impurities May contain minor quantities of sodium chloride or other sodium salts.
4. First-Aid Measures
In the event of an exposure, it is crucial to act swiftly to minimize any potential injuries
- Inhalation Move the affected person to fresh air immediately. If breathing is difficult, administer oxygen and seek medical attention. - Skin Contact Rinse the affected area with plenty of water for at least 15 minutes. Remove contaminated clothing and seek medical help if burns occur. - Eye Contact Rinse immediately with plenty of water or an eye wash solution for at least 15 minutes. Get medical attention immediately. - Ingestion Do not induce vomiting. Rinse mouth and give water to dilute the substance if the person is conscious. Seek medical help immediately.
5. Fire-Fighting Measures
Sodium hydroxide does not burn; however, it may produce flammable hydrogen gas upon contact with certain materials
. In case of a fire involving sodium hydroxide- Use water, foam, dry chemical, or carbon dioxide to extinguish the fire. - Wear self-contained breathing apparatus and full protective gear to avoid exposure to harmful fumes.
6. Accidental Release Measures
In the event of a spill or leak
- Evacuate the area and eliminate all sources of ignition. - Wear appropriate personal protective equipment (PPE) including gloves and goggles. - Absorb the spill with inert material (e.g., sand or vermiculite) and place it into a suitable container for disposal. Do not flush down the drain.
7. Handling and Storage
When handling sodium hydroxide, the following precautions should be taken
- Always wear PPE including gloves, goggles, and face protection. - Avoid contact with incompatible materials such as acids or moisture. - Store in a cool, dry location in a tightly closed container. Ensure that containers are clearly labeled and specify that they contain caustic material.
8. Exposure Controls/Personal Protection
Occupational exposure limits for sodium hydroxide indicate that the following should be adhered to
- TLV (Threshold Limit Value) 2 mg/m³ (as a ceiling limit). - Ensure adequate ventilation in work areas. - Use appropriate PPE gloves resistant to caustic materials, chemical goggles, and aprons.
9. Physical and Chemical Properties
- Appearance Clear, colorless liquid - pH Approximately 13 - Density Variable based on concentration - Solubility Miscible with water
10. Stability and Reactivity
Sodium hydroxide is stable under normal conditions, but it should be kept away from acids, aluminum, and other reactive materials.
Conclusion
In summary, while sodium hydroxide 10% solution is less hazardous than its concentrated forms, appropriate precautions must be taken to ensure safety during handling, storage, and disposal. Always refer to the SDS prior to using the substance to familiarize yourself with all safety and emergency procedures.
