Safety Data Sheet for Caustic Soda (Sodium Hydroxide) 50%

Caustic soda, or sodium hydroxide (NaOH), is a highly corrosive chemical widely used in various industrial applications, including manufacturing, cleaning agents, and water treatment. When handling concentrated solutions—such as 50% caustic soda—it's essential to observe stringent safety precautions to mitigate health risks and environmental concerns.

Chemical Properties

Sodium hydroxide is a white solid that is hygroscopic, meaning it readily absorbs moisture from the air. In its concentrated form, it forms a highly caustic solution that can cause severe chemical burns and eye damage. The pH level of a 50% solution typically exceeds 13, indicating its strong alkaline nature.

Health Hazards

Exposure to caustic soda can occur through skin contact, inhalation of aerosols, or ingestion. Acute exposure can result in serious injuries, including

- Skin contact Can cause severe burns and irritation. Immediate washing with water is crucial. - Eye contact May result in permanent eye damage or blindness. Eye protection must be worn. - Inhalation Can lead to respiratory irritation, pulmonary edema, and other severe lung conditions. - Ingestion Ingesting caustic soda can cause serious internal damage and requires immediate medical attention.

Protective Measures

To ensure safe handling, it is critical to use appropriate personal protective equipment (PPE), including

- Chemical-resistant gloves and protective clothing. - Safety goggles or face shields to protect eyes. - Respiratory protection if adequate ventilation cannot be ensured.

Storage and Spillage

Caustic soda should be stored in a cool, dry place, away from incompatible materials such as acids or oxidizers. Containers must be labeled clearly and kept tightly sealed. In the event of a spill, evacuate the area, and use appropriate neutralizing agents (e.g., vinegar or citric acid) to mitigate the spill, following local hazardous waste disposal regulations.

Emergency Measures

In case of exposure, perform the following

- For skin contact Rinse immediately with copious amounts of water for at least 15 minutes and seek medical assistance. - For eye contact Flush the eyes with water for at least 15 minutes, lifting the eyelids occasionally, and seek immediate medical care. - If inhaled Move the affected individual to fresh air and seek medical attention if respiratory problems arise.

In summary, while caustic soda is a vital chemical in many industries, its safe handling and storage are paramount to prevent accidents and ensure the safety of workers and the environment. Adhering strictly to the guidelines outlined in the Safety Data Sheet is essential for all personnel involved in its use.
