IMO Classification

Class 1: Explosive substances and articles



Class 1: Explosive substances and articles

Materials or objects by means of a chemical reaction off gas temperature or speed may damage which; or materials capable of producing exothermic reactions.

Class 2: Gases



Class 2.1: Flammable gases

Gas at 20 ° C and at a pressure of 101.3 kPa:

  • They are flammable in a mixture of equal to or less than 13 % by volume.
  • It has a flammable range with air of at least 12 %
  • Class 2.2: Non-toxic, non-flammable gases

    Gases which:

  • Diluted, replace or displace oxygen producing air asphyxiation.
  • You have oxidizing properties. Combuctión favor further the air.
  • They can not atribuirsen any of the other classes.
  • Class 2.3: Toxic gases

    If inhaled, cause acute or chronic or irritant effects, and even death. These gases can be flammable, corrosive or oxidizing.

    Class 3: Flammable liquids



    Class 3: Flammable liquids

    These liquids have a flashpoint of 60 ° C. These materials have toxic or corrosive.

    Class 4: Materials by reacting



    Class 4.1: Flammable solids, self-reactive substances and solid desensitized explosives

    They react spontaneously. They are solid under normal conditions of transport are flammable and can promote fire by friction.

    Class 4.2: Materials in contact with water emit flammable gases

    Materials in contact with water, emit flammable gases. The hazard signs usually carry an X preceding the identification of the hazard.

    Class 5: Oxidizing substances



    Class 5.1 Oxidizing substances

    Liquids or solids which may cause or contribute to combustion. Therefore contact with other materials increase the risk of fire occurring and/or favor them.

    Clase 5.2 Organic peroxides

    These are substances which are susceptible to exothermic decomposition at normal or elevated temperatures. Decomposition occurs by heat, contact with impurities, friction or impact.

    Class 6: Toxic substances



    Class 6.1: Toxic substances

    They are materials in small quantities, can damage the health of a human being or cause death by inhalation, skin absorption or ingestion.

    Class 6.2: Infectious substances

  • Materials known or pathogenic agent is believe, that can cause disease or death in living things.
  • Biological products derived from living organisms that require special treatment for transport.
  • Crops laboratory for the study of human or animal disease.
  • Specimens of patients: human or animal materials taken from patients.
  • GMM: any organisms that have been genetically engineered.
  • Medical or clinical wastes disposable items of clinical practice in humans or animals or biological research.
  • Class 7: Radioactive materials



    Class 7: Radioactive materials

    Are objects or materials containing radioisotopes in which both the activity concentration and the total activity in the consignment exceed the minimum values.

    Class 8: Corrosive substances



    Class 8: Corrosive substances

    Materials to contact attack epithelial tissue of the skin, mucous membranes or eyes, also by contact with other materials may result in damage to other goods or property.

    Class 9: Materials and articles which have different hazards



    Class 9: Materials and articles which have different hazards

    Are materials or objects that represent some kind of danger not contemplated among the above dioxins, fine dust that can cause airway Danor, lithium batteries, hazardous substances to the environment, among others.
