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
  • Neutralize with dilute acid (under professional supervision)
  • Collect material and place in appropriate disposal containers
  • Flush area with water after cleanup

Nitric Acid (HNO3) is a highly corrosive, strong acid with a colorless to pale yellow appearance, depending on concentration. It is one of the most important industrial chemicals. Here’s a general description and summary of its usage.

Nitric Acid (HNO3) is produced by the reaction of water with nitrogen dioxide (NO2). Nitric acid is a strong toxic mineral acid and has extremely high corrosive properties. It has the chemical formula HNO3. Nitric acid is also recognized as the spirit of aqua fortis and niter. Nitric acid is colourless in pure form but if it gets older then it will turn into a yellow cast.

Nitric acid could cause severe skin burn if it came under human contact. It reacts with oxides, hydroxides, and metals to form nitrate salts.

Nitric acid is utilized as a powerful oxidizing agent. Approximately the pH of nitric acid is 3.01. Nitric acid is associated with the group of inorganic acids.
