Safety Data Sheet Summary for Sodium Hydrogen Sulphate

Chemical Identity and Composition

Sodium hydrogen sulfate, also known as sodium bisulfate, is an inorganic compound with the formula NaHSO₄. This white crystalline solid is highly soluble in water, forming an acidic solution. Its molecular weight is approximately 120.06 g/mol. Sodium hydrogen sulfate is commonly used in various industrial applications, including pH regulation, cleaning agents, and as an intermediate in chemical synthesis.

Physical and Chemical Properties

Sodium hydrogen sulfate appears as a white or yellowish crystalline powder. It has a melting point of about 150°C, at which it decomposes. The compound is hygroscopic, meaning it can absorb moisture from the environment. With a pH of approximately 1 to 2 in aqueous solutions, it is considered acidic. This property makes it useful in applications requiring pH control or adjustment.

Health Hazards

When handling sodium hydrogen sulfate, it is crucial to be aware of its potential health hazards. The compound can cause irritation to the skin, eyes, and respiratory tract. Inhalation of dust or mist may lead to respiratory problems. Prolonged exposure can result in severe skin burns and eye damage. It is advisable for individuals handling this substance to wear appropriate personal protective equipment (PPE), including gloves, goggles, and respiratory protection if necessary.

Environmental Impact

Sodium hydrogen sulfate can be harmful to aquatic life if released into water bodies. Its acidity can lower the pH of natural water systems, negatively impacting aquatic organisms. Therefore, it is essential to manage its disposal properly and prevent spillage during transportation or storage. Companies must adhere to local environmental regulations regarding disposal and report any uncontrolled releases to the relevant authorities.

First Aid Measures

In case of exposure to sodium hydrogen sulfate, immediate action is crucial. For skin contact, remove contaminated clothing and gently wash the affected area with soap and water for at least 15 minutes. If the skin becomes irritated, seek medical attention. In the event of eye contact, rinse the eyes with water for at least 15 minutes and seek medical help. If inhaled, move the individual to fresh air and seek medical attention if respiratory distress occurs. Ingestion of the substance can cause severe harm; do not induce vomiting and seek immediate medical assistance.

Handling and Storage

Sodium hydrogen sulfate should be stored in a cool, dry, well-ventilated area, away from incompatible substances such as strong bases and oxidizing agents. Containers should be tightly sealed when not in use to prevent moisture absorption and contamination. During handling, it is important to minimize dust generation and use appropriate PPE. Use mechanical ventilation or local exhaust to keep airborne concentrations below permissible limits.

Regulatory Information

Sodium hydrogen sulfate is regulated under various local and international standards. Users must familiarize themselves with the relevant regulations related to chemical handling, storage, and disposal. Material Safety Data Sheets (MSDS) should be readily available to all employees handling this substance, ensuring that safety protocols are followed.

Conclusion

Sodium hydrogen sulfate is a valuable compound widely used in many industries. However, its safety hazards and environmental impact necessitate careful handling and adherence to regulatory guidelines. By implementing proper safety measures and ensuring that personnel are well-informed, the risks associated with this substance can be minimized, promoting a safe working environment while leveraging its benefits in industrial applications.
