UN 2468: TRICHLOROISOCYANURIC ACID, DRY IMDG Class: 5.1 / Packing Group: II CAS:87-90-1

TRICHLOROISOCYANURIC ACID "TCCA" is mainly used to disinfect and sterilize drinking water, industrial water recycling, swimming pools, restaurants, hotels,?public places, homes, hospitals, and eggs, as well as to prevent fish diseases. It kills almost all fungi, bacteria, viruses, and spores. It is also?used as a bleaching agent in the textile industry.

Properties and Observations

• Colourless powder or granules.
• Chlorine odor.
• Mixtures with combustible material are sensitive to friction and are liable to ignite.
• In contact with nitrogen compounds, fumes of nitrogen trichloride can be formed, which are very explosive.
• Harmful by inhalation.
• Irritating to skin, eyes and mucous membranes.

Stability:

• Chemical Stability:?Stable under normal temperatures and pressures.
• Hygroscopic and may decompose in contact with moisture.
• Contact with combustible material may lead to fire.
• Incompatible with acids, reducing agents, water, and?strong oxidizing agents.
• Hazardous Decomposition Products: Hydrogen chloride, nitrogen oxides, carbon monoxide, irritating and toxic fumes and gases, carbon dioxide, nitrogen.

Please keep it as dry as you can.

• In a fire, exposed cargoes may explode, or their containment may rupture.

One example is the irresponsible handling and storage of chemical products, which can lead to unsafe situations and pose risks to the surrounding environment.

One manufacturing facility in Conyers, US, releases chlorine, chloramines, and chlorine compounds from a small rooftop fire on 29 September. The fire activated a sprinkler system and doused water-reactive TRICHLOROISOCYANURIC ACID (TCCA) inside the building, triggering a chemical decomposition reaction that released chlorine gas into the atmosphere, posing a potential danger to the area.

Thousands of residents evacuated and kept indoors as smoke and gas clouds persisted for days.

An ongoing threat?is that the cloud of smoke, chlorine, and other decomposition products continues to drift across the area. Rising levels at night are keeping residents confined indoors, highlighting the persistent danger.

The facility's history of similar incidents has raised serious concern among local authorities. This has led to several new class action lawsuits against the facility and affiliates. State lawmakers and local activists are now advocating for the plant's permanent shutdown, emphasizing the need for a lasting solution.
