Trichloroisocyanuric Acid (TCCA) is a white, crystalline, or granular solid with a strong chlorine odor. It is a powerful chlorinating agent commonly used for water treatment, sanitation, and disinfection. The “90” refers to its high concentration of available chlorine, typically around 90%, making it one of the most efficient chlorine sources for various applications.

Applications:

1. Water Treatment:
   • Swimming Pools: Used for disinfection, controlling algae growth, and maintaining proper chlorine levels in swimming pools.
   • Drinking Water: Acts as a disinfectant in water treatment plants for potable water systems.
   • Industrial Water Treatment: Applied to sanitize cooling towers, wastewater treatment plants, and other industrial water systems.
2. Disinfection:
   • Public Sanitation: Used for sanitizing public spaces, hospitals, and disinfecting surfaces.
   • Food Processing: Employed to disinfect equipment, storage areas, and surfaces in the food and beverage industry.
3. Bleaching Agent:
   • Textile Industry: Used for bleaching and whitening fabrics.
   • Paper Industry: Applied as a bleaching agent in the paper pulp manufacturing process.
4. Algaecide and Fungicide:
   • Agriculture: Utilized as an algaecide and fungicide in agricultural irrigation systems and ponds.
5. Household Use:
   • Found in household cleaning and disinfectant products due to its strong bactericidal, virucidal, and algicidal properties.

Handling and Safety:

• Personal Protection:
  • Wear protective clothing, gloves, goggles, and a mask to prevent contact with the skin, eyes, or inhalation of dust or fumes.
  • Work in a well-ventilated area, preferably using a respirator if chlorine gas is a risk.
• Hazards:
  • Inhalation: Chlorine gas released from TCCA can cause respiratory irritation, coughing, and difficulty breathing.
  • Skin Contact: Causes irritation or burns upon direct contact with skin.
  • Ingestion: Toxic if swallowed, leading to severe internal damage.
  • Reactivity: Avoid contact with water during storage, as it can release hazardous chlorine gas. TCCA also reacts violently with ammonia, ammonium salts, and organic materials, potentially causing fires or explosions.
• Spill Response:
  • In case of spillage, avoid raising dust and use non-combustible absorbent material. Ventilate the area and collect spilled material for disposal according to local regulations.
  • Do not let it enter water systems directly without treatment.

Storage:

• Storage Conditions:
  • Store in a cool, dry, and well-ventilated area away from direct sunlight, moisture, heat, or any reactive substances like acids or alkalis.
  • Keep containers tightly sealed to prevent moisture from entering, which could lead to decomposition and chlorine gas release.
• Container Requirements:
  • Store in non-metallic containers made of plastic or other compatible materials. Metal containers may corrode over time.
• Stability:
  • TCCA is stable under dry conditions. However, it decomposes when exposed to moisture or heat, releasing chlorine gas and other hazardous by-products.

By following these handling and storage guidelines, TCCA 90 can be used safely and effectively for a wide range of disinfection, water treatment, and bleaching applications.
