Sodium Bisulfate (Sodium Hydrogen Sulfate) - Safety Data Sheet (MSDS)

Safety Data Sheet Overview for Sodium Bisulfate

Sodium bisulfate, also known as sodium hydrogen sulfate, is a chemical compound with the formula NaHSO₄. It is a white to off-white crystalline powder that is hygroscopic and soluble in water. It is commonly used in various applications including as a cleaning agent, food additive, pH control agent in swimming pools, and in industrial processes. Understanding the safety and handling of sodium bisulfate is crucial, and that is where the Material Safety Data Sheet (MSDS) comes into play.

Chemical Identification

The MSDS for sodium bisulfate provides essential information about the chemical's identity, including its name, CAS number (7681-38-1), and molecular structure. Such details are important for proper identification and for safety while handling the compound in different environments.

Hazard Identification

Sodium bisulfate is classified as a corrosive substance. Ingesting sodium bisulfate can cause severe damage to the respiratory tract, skin, and eyes. The MSDS highlights that exposure can lead to respiratory distress, skin irritation, and severe eye damage upon contact. Proper labeling and clear hazard warnings must be followed to ensure safety.

Composition/Information on Ingredients

The MSDS provides comprehensive information on the chemical composition of sodium bisulfate, typically highlighting that it is composed of sodium (Na), hydrogen (H), sulfur (S), and oxygen (O). Understanding the molecular composition helps in different scientific and industrial applications and ensures safe and effective use.

First-Aid Measures

In any case of exposure, the MSDS outlines the appropriate first-aid measures. If sodium bisulfate comes into contact with skin, it should be washed immediately with plenty of water. For eye contact, flush the affected eyes with water for at least 15 minutes and seek medical attention if irritation persists. In cases of inhalation, moving to fresh air and seeking medical assistance is crucial, particularly if breathing becomes difficult.

Fire Fighting Measures

Although sodium bisulfate is not flammable, in the event of a fire, it may release harmful fumes. The MSDS advises using appropriate extinguishing agents, such as water spray or dry chemical, and personal protective equipment such as self-contained breathing apparatus should be employed as necessary.

Handling and Storage

The MSDS emphasizes safe handling practices, which include using gloves and goggles to avoid direct contact with skin and eyes. Sodium bisulfate should be stored in a cool, dry place in tightly closed containers to prevent moisture absorption, which can impact its stability.

Exposure Controls/Personal Protection

To minimize exposure, the MSDS recommends implementing engineering controls such as adequate ventilation in areas where sodium bisulfate is used. Personal protective equipment (PPE) such as gloves, goggles, and respirators may also be necessary depending on the exposure limits and operational circumstances.

Conclusion

In conclusion, the MSDS for sodium bisulfate is an essential document that provides vital information regarding its safe use, potential hazards, and first-aid measures. It is critical for manufacturers, users, and response teams to understand this information to ensure safety in handling this versatile compound. Adhering to the guidelines outlined in the MSDS can help prevent accidents and ensure a safe working environment when using sodium bisulfate in various applications. Always consult the MSDS before engaging with chemical substances to uphold the highest safety standards.
