Corrosive acidic organic liquid, N.O.S. - UN 3265Transport code 88 / 3265
Corrosive acidic organic liquids play an important role in various industrial processes. These substances are identified by the UN number 3265 and require special precautions. In the following we will explain some important representatives of this group, their properties and applications as well as safety measures.

Examples of UN 3265 substances

Acetic anhydride

  • Properties: Acetic anhydride is a colorless, corrosive liquid that is used in particular in chemical synthesis for the production of acetic acid esters and acetates.
  • Use: Its application extends to the production of chemical compounds in industry, where it acts as a reagent and catalyst.

Methanesulfonic acid

  • Properties: Methanesulfonic acid is a highly corrosive, clear liquid.
  • Uses: This acid is often used as a catalyst and plays an essential role in electroplating, where it helps to improve conductivity and efficiency.

Trifluoroacetic acid

  • Properties: Trifluoroacetic acid is a colorless, fuming liquid with a pungent odor.
  • Use: In organic chemistry, it is used as a solvent and reagent. Its special property of dissolving easily in water and organic solvents makes it versatile.
UN 3265: Classification and safety measures

These substances fall under classification UN 3265, which includes highly corrosive acidic organic liquids.

Substance: Corrosive acidic organic liquid, N.O.S.
UN number: 3265
Hazard number: 88
ADR Class: 8 (Corrosive substances)
Classification code: C3
Packing group: III
ERI-Card: 8-28

Properties and dangers

  • These substances are highly corrosive and can cause serious damage to the skin, eyes and respiratory tract.
  • They have a flash point above 60°C or are non-flammable.
  • Exposure to heat can lead to an increase in pressure and explosion. The resulting vapors are irritating and can corrode metals, resulting in the release of hydrogen gas.

Protective measures

  • Wear a chemical protection suit (CSA full protection) to avoid direct contact.
  • If the substance escapes: Close the leaks, collect the liquid and absorb it with suitable materials.
  • In case of fire: Cool container with water and knock down fire gases with a spray jet.

First aid

  • Eyes: Rinse immediately with water for at least 15 minutes and seek medical attention.
  • Skin: Remove contaminated clothing and rinse affected skin thoroughly with water.
  • Inhalation: Supply fresh air and seek medical help.

The correct classification

The correct classification of substances for transportation, especially in the context of dangerous goods transportation, requires specialist knowledge and experience in the field of dangerous goods regulations. There are various experts and resources that can help with the classification of substances:

  • Dangerous goods officer: Many companies that transport dangerous goods have specially trained dangerous goods officers. These persons are responsible for the safe handling, labeling and documentation of dangerous goods.
  • Dangerous goods consultants: External dangerous goods consultants are experts who can support companies in the proper classification, labeling and documentation of dangerous goods. They have specialist knowledge of the applicable regulations and can help with the classification of substances..
  • Authorities and regulatory bodies: The relevant national and international authorities and regulatory bodies, such as the Federal Office for Logistics and Mobility (BALM) in Germany or the United Nations Economic Commission for Europe (UNECE), provide guidelines and regulations for the transportation of dangerous goods. They can also answer questions about the classification of substances.
  • Databases and resources: There are databases and resources that provide information on various hazardous substances and their classification according to international regulations. These can be used as reference works.
  • Training courses and seminars: Participation in training courses and seminars on the subject of dangerous goods transportation can help companies and individuals to acquire the necessary knowledge for the correct classification of substances.

It is important to consult the relevant national and international regulations and guidelines and always consult experts in case of uncertainty or questions to ensure that dangerous goods are transported safely and legally. The classification of substances is crucial to avoid accidents and hazards.

Conclusion

The safe handling of corrosive acidic organic liquids, which fall under UN number 3265, is essential to avoid serious damage to health and the environment. The combination 88 / 3265 indicates particularly hazardous substances that have strong corrosive effects and specific safety requirements. Correct labeling, the use of suitable protective measures and compliance with first aid measures will ensure safe handling. Invest in appropriate warning signs and protective equipment to maximize safety when handling these hazardous substances.
