Safety Data Sheet (SDS) for Sodium Hydroxide 10%

Introduction Sodium hydroxide, commonly known as caustic soda or lye, is a highly versatile chemical used widely across various industries including chemical manufacturing, food processing, and wastewater treatment. In its 10% solution form, sodium hydroxide retains its highly corrosive properties while being manageable for various applications. This article provides an overview of the safety data sheet (SDS) for sodium hydroxide 10%, emphasizing important safety, handling, and emergency response information.

Sodium hydroxide is a strong base and readily dissolves in water, releasing heat in an exothermic reaction. The 10% concentration is often used for applications that require moderate causticity while reducing the hazards associated with higher concentrations.

Hazard Identification Sodium hydroxide 10% poses several hazards - Corrosive Causes severe skin burns and eye damage. - Harmful if inhaled Can cause respiratory issues if aerosols or mists are generated. - Environmental Risk May cause long-term adverse effects in aquatic environments.

Handling and Storage To ensure safe handling of sodium hydroxide 10%, follow these recommendations - Storage Store in a cool, dry, well-ventilated area away from incompatible materials such as acids. Use corrosion-resistant containers, preferably made of plastic or glass. - Personal Protective Equipment (PPE) Wear appropriate gloves (nitrile or neoprene), goggles, and face shields to protect against splashes. An apron or protective clothing should be worn to avoid skin contact. - Ventilation Ensure adequate ventilation in work areas to minimize exposure to vapors or dust.

First Aid Measures In case of exposure, follow these first aid steps - Skin Contact Immediately remove contaminated clothing and rinse affected skin with plenty of water for at least 15 minutes. Seek medical attention if irritation persists. - Eye Contact Flush eyes immediately with water for at least 15 minutes while holding eyelids open. Get medical attention immediately. - Inhalation Move the affected person to fresh air. If breathing is difficult, administer oxygen and seek medical assistance. - Ingestion Do not induce vomiting. Rinse mouth with water and seek medical attention immediately.

Fire Fighting Measures Sodium hydroxide is not flammable, but the heat generated during its dissolution in water can ignite combustible materials. In case of fire - Extinguishing Media Use appropriate extinguishing agents for the materials involved in the fire. Water can be used to cool containers to prevent pressure build-up. - Protective Equipment Firefighters should wear self-contained breathing apparatus (SCBA) and full protective gear.

Accidental Release Measures In the event of a spill - Personal Precautions Wear appropriate PPE and evacuate non-essential personnel from the area. - Containment Stop the leak if safe to do so. Absorb the spill with inert material and dispose of it in accordance with local regulations. - Cleanup Neutralize residues with a weak acid (e.g., vinegar) before cleaning up.

Exposure Controls/Personal Protection To minimize exposure - Occupational Exposure Limits Follow local regulations and guidelines for permissible exposure limits. The American Conference of Governmental Industrial Hygienists (ACGIH) recommends using engineering controls, such as fume hoods or local exhaust ventilation. - Monitoring Conduct regular air monitoring and health assessments for workers who may be exposed to sodium hydroxide.

Environmental Considerations Sodium hydroxide can pose risks to aquatic environments. It is essential to avoid discharge into water bodies. In the event of an environmental release, notify local authorities and follow all regulatory requirements for environmental protection.

Conclusion Sodium hydroxide 10% is a useful yet hazardous chemical that requires strict adherence to safety practices outlined in its safety data sheet. Proper storage, handling, and emergency preparedness are critical to ensuring safety. By following these guidelines, workers and employers can mitigate risks associated with sodium hydroxide and maintain a safe working environment. Always refer to the latest SDS for detailed information and guidance tailored to specific situations.
