Calcium Hydroxide(Hydrated lime) , also known as hydrated lime, is a chemical compound with the formula Ca(OH)2. It is a white, odorless, and alkaline substance that is produced by adding water to calcium oxide, also known as quicklime. The resulting reaction produces calcium hydroxide and releases a large amount of heat.
Hydrated lime is commonly used in various industrial applications such as water treatment, construction, agriculture, and food processing. It is also used as a pH regulator and a flocculant in wastewater treatment plants. Additionally, it is used in the production of cement, as a soil stabilizer, and in the manufacture of chemicals such as calcium stearate and calcium hypochlorite.
In summary, calcium hydroxide, or hydrated lime, is a chemical compound with various industrial applications, produced by adding water to calcium oxide.

Personal Protection
- Respiratory Protection: Use a dust mask (NIOSH N95 or higher)when handling powder to prevent inhalation of dust particles.
- Eye Protection: Wear safety gogglesto prevent eye irritation from dust or splashes.
- Skin Protection: Use impermeable gloves (nitrile or neoprene)to avoid skin contact, especially with concentrated solutions.
- General Hygiene: Avoid ingestion and prolonged skin exposure. Wash hands thoroughly after handling.
Handling & Storage
- Store in a cool, dry, well-ventilatedarea, away from moisture and incompatible chemicals (e.g., strong oxidizers).
- Keep containers tightly sealedto prevent absorption of moisture (hygroscopic).
- Use non-sparking toolswhen handling large quantities.
- Avoid contact with water(exothermic dissolution, may cause splattering).
Spill Management
- For dry spills: Sweep up carefully (avoid dust generation) and dispose of in a sealed container.
- For liquid spills (solution): Absorb with inert material (e.g., vermiculite, sand) and clean with water.
- Large spills: Contain and prevent entry into drains or waterways (may be harmful to aquatic life).
Inhalation
- Move to fresh air
- If breathing difficulties occur, seek medical attention.
Skin Contact
- Remove contaminated clothing.
- Rinse affected area with plenty of water for at least 15 minutes.
- If irritation or burns develop, seek medical attention.
Eye Contact
- Rinse immediately with lukewarm water for at least 15 minutes, holding eyelids open.
