Safety Data Sheet (SDS) for Sodium Hydroxide Solid

Sodium hydroxide (NaOH), commonly known as lye or caustic soda, is a highly alkaline compound with a wide range of uses in various industries, including chemical manufacturing, food processing, and soap making. Given its corrosive properties, it is essential to understand the safety measures and handling protocols associated with sodium hydroxide solid to prevent health hazards and ensure safe usage.

Chemical Identification

Sodium hydroxide is an odorless, white solid that is highly soluble in water, generating a strongly alkaline solution. The chemical formula for sodium hydroxide is NaOH, and it typically appears as pellets, flakes, or granules. Its primary uses include pH regulation, grease removal, and as a key reactant in the production of biodiesel, paper, and textiles.

Hazards Identification

The significant hazards associated with sodium hydroxide include its corrosivity and the potential for severe injuries upon contact with skin or eyes. It can cause chemical burns, tissue damage, and respiratory issues if inhaled as dust or aerosol. Ingestion can lead to severe internal burns and necessitates immediate medical attention. Additional hazards include environmental risks if released into water bodies, as sodium hydroxide can severely alter the pH levels, adversely affecting aquatic life.

Composition/Information on Ingredients

- Chemical Name Sodium Hydroxide - CAS Number 1310-73-2 - Ingredients Sodium hydroxide (100%)

First-Aid Measures

In case of an exposure incident, it is crucial to follow specific first-aid measures

- Inhalation Move the affected individual to fresh air immediately. Seek medical attention if breathing difficulties arise. - Skin Contact Rinse the affected area with plenty of water for at least 15 minutes. Remove contaminated clothing and seek medical advice. - Eye Contact Rinse eyes cautiously with water for several minutes. Remove contact lenses if present and easy to do. Continue rinsing and seek immediate medical help. - Ingestion Do not induce vomiting. Rinse the mouth and seek medical attention promptly.

Fire-Fighting Measures

Sodium hydroxide is non-flammable; however, it may react with certain materials to produce heat. In the event of a fire involving sodium hydroxide, use dry chemical, carbon dioxide, or foam extinguishing agents. Stress the importance of wearing appropriate protective gear, including self-contained breathing apparatus (SCBA) and full protective clothing, to prevent exposure to hazardous fumes.

Handling and Storage

When handling sodium hydroxide, it is essential to adopt appropriate safety precautions

- Personal Protective Equipment (PPE) Wear eye protection, face shields, gloves, and protective clothing. - Storage Store sodium hydroxide in a cool, dry, well-ventilated area, away from incompatible substances such as acids and metals. Containers should be tightly sealed and labeled clearly.

Exposure Controls/Personal Protection

Employ engineering controls to reduce exposure to sodium hydroxide in the workplace. This may include the use of exhaust ventilation systems or local exhaust hoods. Regular monitoring of workplace air quality can also help ensure that exposure levels are within acceptable limits.

Environmental Considerations

Sodium hydroxide poses a risk to aquatic environments due to its high pH levels. In case of a spill, neutralize the compound with a weak acid before disposal, following all relevant local regulations regarding hazardous waste. Always report any large spills to the appropriate environmental authorities.

Conclusion

Understanding the safety data sheet (SDS) for sodium hydroxide solid is crucial for safely handling and storing this substance. With its wide uses across several industries, proper knowledge and adherence to safety protocols can effectively mitigate risks associated with its hazardous nature, ensuring a safer working environment for all.
