Safety Data Sheet (SDS) for Sodium Bisulfate

Introduction

Sodium bisulfate, also known as sodium hydrogen sulfate, is an important chemical used in various industrial applications. With the CAS number 7681-38-1, this compound is a white crystalline powder that is hygroscopic in nature. Primarily used as a pH adjuster, it finds applications in the food industry, water treatment, textile manufacturing, and as a laboratory reagent. Understanding the safety data associated with sodium bisulfate is crucial for ensuring safe handling and use.

Chemical Properties

Sodium bisulfate has a molecular formula of NaHSO4 and a molar mass of 120.06 g/mol. It is highly soluble in water, producing an acidic solution, which highlights its efficiency as a pH regulator. The substance is characterized by a low melting point, approximately 315 °C, and can decompose when heated, releasing harmful gases. This emphasizes the importance of storage conditions and handling protocols to prevent any potential hazards.

Health Hazards

The safety profile of sodium bisulfate indicates that it can pose health risks if not handled properly. According to the Safety Data Sheet (SDS), exposure to sodium bisulfate can cause serious health effects.

- Inhalation Breathing in sodium bisulfate dust may result in respiratory tract irritation. Chronic exposure can lead to more serious respiratory issues.

- Skin Contact Contact with the skin may lead to irritation or burns, especially in sensitive individuals. Proper protective gear such as gloves and clothing is recommended when handling this chemical.

- Eye Contact Sodium bisulfate is a severe irritant to the eyes and can cause permanent damage. In case of contact, it is crucial to rinse the eyes with plenty of water and seek medical attention immediately.

- Ingestion Ingesting sodium bisulfate can cause gastrointestinal irritation, including nausea, vomiting, and abdominal pain. It is critical to avoid eating or drinking in areas where sodium bisulfate is handled to minimize the risk of accidental ingestion.

Environmental Hazards

Sodium bisulfate is considered hazardous to the aquatic environment. It can lead to pH changes in water bodies, which in turn may adversely affect aquatic life. It is important to prevent the release of sodium bisulfate into the environment by adopting appropriate disposal methods and spill management practices.

Handling and Storage

When working with sodium bisulfate, it is essential to follow strict safety protocols to minimize risks

- Personal Protective Equipment (PPE) Always use appropriate PPE, including safety goggles, gloves, and protective clothing. A face mask or respirator may also be necessary in poorly ventilated areas to prevent inhalation of dust.

- Ventilation Ensure adequate ventilation in the workspace. Using fume hoods or working in well-ventilated areas can help reduce inhalation risks.

- Storage Sodium bisulfate should be stored in a cool, dry place, away from incompatible substances such as strong bases and powerful oxidizers. Containers should be tightly sealed to avoid moisture absorption.

- Disposal Disposal of sodium bisulfate should be carried out in accordance with local regulations. It is advisable to consult the local waste disposal authority for guidance on the proper disposal of hazardous materials.

Emergency Procedures

In case of an emergency involving sodium bisulfate, it is important to have clear procedures in place

- Spills In the event of a spill, evacuate the area and use appropriate spill containment methods. Neutralize the spill with a compatible material, and ensure proper cleanup and disposal.

- First Aid Measures Familiarize yourself with first aid measures for exposure. If inhaled, remove the person to fresh air. For skin contact, rinse thoroughly with water for at least 15 minutes. In case of eye contact, flush with water for at least 15 minutes and seek medical attention.

Conclusion

Sodium bisulfate is a versatile chemical with a wide range of applications. However, with its utility comes responsibility. Understanding the hazards associated with sodium bisulfate and adhering to safety guidelines is vital for protecting both human health and the environment. Always consult the Safety Data Sheet before handling this chemical to ensure a safe working environment. By taking the necessary precautions, we can safely utilize the benefits of sodium bisulfate while minimizing its associated risks.
