- Skin Protection: Use gloves (nitrile or latex)and long sleeves if prolonged exposure is expected.
- General Hygiene: Avoid inhalation and ingestion. Wash hands after handling.
Handling & Storage
- Store in a cool, dry, well-ventilatedarea away from acids.
- Keep containers tightly closedto prevent moisture absorption.
- Minimize dust generation; use local exhaust ventilationif necessary.
- Avoid contact with strong acids(can release CO₂ gas).
Spill Management
- Sweep up spills (avoid dust generation) and dispose of properly.
- Wash contaminated surfaces with water.
Inhalation
- Move to fresh air
- If breathing difficulties occur, seek medical attention.
Skin Contact
- Wash affected area with soap and water.
- If irritation develops, seek medical advice.
Eye Contact
- Rinse immediately with plenty of water for 15 minutes, lifting eyelids occasionally.

Aluminium sulphate Alum Rock
Aluminium sulphate, also known as alum, is a chemical compound made up of aluminium, sulphur and oxygen. It has the chemical formula Al2(SO4)3 and is commonly used in water treatment plants as a coagulant to remove impurities such as suspended particles, organic matter, and bacteria from water.
Alum is a white crystalline substance that dissolves in water to form a colourless solution. It has a variety of other applications, including in the manufacturing of paper, textiles, and in various industrial processes. In addition, alum has medicinal uses as an astringent and as a component of antiperspirants.
Ammonium bicarbonate
Ammonium bicarbonate is a white, crystalline compound with the chemical formula NH4HCO3. It is a type of inorganic salt that is commonly used in the food industry as a leavening agent for baking, as well as in the production of ceramics, dyes, and other chemicals. When heated, ammonium bicarbonate decomposes into ammonia, carbon dioxide, and water vapor, which causes dough to rise and become light and fluffy. It is also known as hartshorn or baker's ammonia.
Ammonium sulphate
Ammonium Sulphate [(NH₄)₂SO₄] is a white crystalline salt widely used as a high-efficiency fertilizer, providing 21% nitrogen and 24% sulfur for optimal plant growth. It improves soil fertility, lowers pH in alkaline soils, and enhances crop yields. Beyond agriculture, it serves as a flame retardant, protein purification agent in labs, dough conditioner (E517) in food processing, and dye auxiliary in textiles. Soluble in water, it’s also used in water treatment, leather tanning, and industrial chemicals. A cost-effective dual-nutrient source, it’s ideal for sulfur-deficient soils.
