Safety Data Sheet for Sodium Hydroxide 25%

Sodium hydroxide, commonly known as caustic soda or lye, is a highly versatile chemical widely used in various industries, including manufacturing, food production, and laboratories. The 25% solution of sodium hydroxide is particularly significant due to its concentrated nature, requiring careful handling and awareness of its safety data sheet (SDS).

Physical and Chemical Properties

Sodium hydroxide appears as a clear, colorless liquid with a strong alkaline pH, typically around 13. The chemical formula is NaOH, and its molecular weight is 40.00 g/mol. It is highly soluble in water, releasing a considerable amount of heat during the dissolution process. This exothermic reaction can lead to burns if proper precautions are not taken.

Hazards Identification

Sodium hydroxide 25% is classified as a corrosive substance. Direct contact with skin and eyes can cause severe burns and damage tissues. When inhaled, it can irritate the respiratory tract, leading to coughing or difficulty in breathing. Ingestion of sodium hydroxide can cause serious harm to the gastrointestinal tract. Consequently, it is essential to always wear appropriate personal protective equipment (PPE), including gloves, goggles, and face shields when handling this chemical.

First Aid Measures

In case of exposure, quick action is essential. For skin contact, immediately rinse the affected area with plenty of water for at least 15 minutes and seek medical attention. If sodium hydroxide enters the eyes, flush them thoroughly with water while keeping the eyelids open, and seek emergency medical assistance. If inhaled, move the individual to fresh air and provide artificial respiration if breathing has stopped. Ingestion requires immediate medical attention; do not induce vomiting.

Handling and Storage

To minimize risks, sodium hydroxide should be stored in a tightly sealed container in a cool, dry place away from incompatible substances such as acids and organic materials. It should always be handled in a well-ventilated area to prevent inhalation of vapors. Moreover, all containers should be clearly labeled to indicate the chemical and its hazards.

Conclusion

Understanding the safety data sheet for sodium hydroxide 25% is crucial for anyone who handles this substance. By adhering to recommended safety practices and procedures, the risks associated with this powerful alkalizing agent can be effectively managed, ensuring a safer working environment. Regular training and awareness are essential components in fostering a culture of safety when working with hazardous materials.
