Answer (1)
Toxic and infectious substances is a hazard classification of dangerous goods. These pose unique biological and chemical threats. Toxic substances may harm through chemical action, while infectious substances can spread diseases and even start epidemics if not contained properly.These substances need strict containment, often including double packaging, refrigeration, or labeling for biohazard risks. Transporters must know exactly how to handle spills or leaks, which differ greatly from handling flammable or corrosive goods. Mishandling can cause legal liabilities, workplace shutdowns, or international alerts, especially with contagious biological agents.Exposure can result in severe poisoning, contamination, or disease outbreaks. For instance, a leak of a toxic gas like phosgene is life-threatening, and a broken vial of Ebola virus can risk public health. Under the United Nations classification system for the transportation of dangerous goods, Class 6 refers to Toxic and Infectious Substances.6.1 – Toxic SubstancesThese are materials that can cause death, injury, or harm to human health if swallowed, inhaled, or in contact with skin.Ars/enic compounds (e.g., ars/enic trioxide)Cyanides (e.g., sodium cyanide, potassium cyanide)Mercury compounds (e.g., mercuric chloride)Chloropicrin – a toxic pesticideAniline – a toxic organic compound used in dyesNicotine – in concentrated forms, used in pesticides6.2 – Infectious SubstancesThese contain pathogens (bacteria, viruses, parasites, fungi, or other microorganisms) that can cause diseases in humans or animals.Ebola virus samplesAnthrax spores (Bacillus anthracis)Salmonella culturesHIV specimensTuberculosis cultures (Mycobacterium tuberculosis)Swine fever virus samples
