Safety Information & Handling

⚠️ WARNING: Highly Corrosive Material

Sodium Hydroxide is a highly corrosive substance. Proper safety precautions must be followed during handling, storage, and use. Always refer to the complete MSDS before handling.

Personal Protection Equipment (PPE)

Eye Protection: Chemical safety goggles or face shield (mandatory)
Hand Protection: Chemical-resistant gloves (rubber, neoprene, or PVC)
Body Protection: Chemical-resistant apron or full protective suit
Respiratory Protection: Use in well-ventilated areas; respirator if required
Footwear: Chemical-resistant safety boots

First Aid Measures

Eye Contact: Immediately flush with plenty of water for at least 15 minutes. Seek medical attention immediately.
Skin Contact: Remove contaminated clothing. Wash affected area with plenty of water and soap. Seek medical attention if irritation persists.
Inhalation: Move to fresh air immediately. If breathing is difficult, give oxygen. Seek medical attention.
Ingestion: Do NOT induce vomiting. Rinse mouth with water. Give water or milk to drink. Seek immediate medical attention.

Fire Fighting Measures

Non-combustible. However, contact with water generates heat and may cause spattering. Use dry chemical, CO₂, or water spray to fight fires involving caustic soda. Wear full protective equipment including self-contained breathing apparatus.

Spill & Leak Procedures

Evacuate area and ventilate thoroughly
Wear appropriate PPE before cleanup
Contain spill to prevent environmental contamination

Product Description

Calcium Chloride (CaCl₂) is a highly versatile chemical compound made up of calcium and chlorine. It is commonly found as a white, odorless salt in both anhydrous and hydrated forms.

Calcium Chloride is a ready-to-use white powder. It is non-toxic, odorless, extremely hygroscopic, and easily soluble in water to form a slightly acidic solution. It can be used to achieve rapid density increase with minimum volume addition. It also provides inhibition, preventing the hydration and migration of swelling clays and can be used in packer fluids. Calcium Chloride is available in anhydrous (CaCl2) and dihydrate (CaCl2•H2O) in forms of prills, powder, granule or flakes.

Technical Specifications

Parameter	Specification	Test Method
Appearance	White, odorless crystalline solid or granules (in anhydrous form), and may appear as a colorless or white crystalline substance in its hydrated form.
Solubility	Highly soluble in water, which releases a large amount of heat. It is also deliquescent, meaning it absorbs moisture from the air.
Chemical Formula	CaCl₂
Melting Point	Around 772°C (1422°F)
Boiling Point	Decomposes rather than boiling at around 1,935°C (3,515°F)
Hygroscopic	Absorbs water from its surroundings, which is a key property used in several applications.

Industrial Applications

De-icing and Anti-icing

Calcium chloride is widely used for melting ice on roads, sidewalks, and runways in winter due to its ability to lower the freezing point of water.

Dust Control

It is used for controlling dust on unpaved roads and construction sites by absorbing moisture and binding dust particles together.

Food Industry

Used as a food additive (E509) for improving texture and firmness, especially in canned vegetables and fruits. It is also used in cheese making and as a pickling agent.

Construction

Used as a setting accelerator in concrete, helping to speed up curing time in cold weather.

Desiccant

Anhydrous calcium chloride is used in desiccators to remove moisture from gases or liquids and is also used in some packaging to keep items dry.

Water Treatment

It is used in water treatment plants to help with softening water by replacing sodium ions with calcium ions, which reduce water hardness.

Agriculture

It’s used in some cases for soil conditioning or for providing calcium to plants in certain soils.
