www.truckandtrack.com Autumn 2026 Truck and Track 67 DANGEROUS GOODS is an essential medical tool (administering gaseous Oxygen to the infected’ What is the term “Oxygen Cleaned’? Equipment used with Oxygen, such as regulators, hoses, pipework, and measuring instruments/apparatus etc must be ‘Oxygen Cleaned’. This term refers to the removal of any dirt, hydrocarbon-based lubricants, greases and waxes from surfaces that may come into contact. Oxygen will react with these materials aggressively, especially if under pressure (or subject to elevated temperature). The Oxygen cylinder and liquid vessels always have the ‘Use no Oils or Greases’ warning labels. Because of the ubiquity of the Oxygen Cylinder as GOX (and Nitrous Oxide NOX) as well as LOX (cryogenically liquefied O2) in medical use, there have been serious incidents in hospitals, when a dab of (hydrocarbon based) moisturising hand-cream (from a nurse) or paramedic is inadvertently smeared on a valve when cylinders are being changed. Incidents in welding occur when Oxygen and Acetylene (an energetic hydrocarbon) come into contact in an accidental manner, usually by an untrained operator. Security There are security concerns in our current geo-political situation, regarding Oxygen as LOX and GOX; as well as the Oxidising Agents (class 5.1) and Organic Peroxides (class 5.2) which when consigned in bulk are termed High Consequence Dangerous Goods (HCDG) under ADR/IMDG regulations. These products can be used nefariously (in-conjunction with other products) to pose a significant threat to society. Other Oxidising Agents Gases: fluorine, chlorine, bromine, ozone, nitrous oxide Liquids: hydrogen peroxide, nitric acid, perchloric acid, bromine, sulphuric acid Solids: nitrites, nitrates, perchlorates, chromates, dichromates, picrates, permanganates, hypochlorites, bromates, iodates, chlorites, chlorates, persulphates. Other Problematical Reactivity Hazards ■ Compounds containing the functional groups: azide, acetylide, diazo, nitroso, haloamine, peroxide, and ozonide are shock and heat sensitive and can explode violently. ■ Some organic compounds such as ethers, tetrahydrofuran (THF), and dioxan can react with oxygen (from the air) forming unstable peroxides which can result in explosion and fire. ■ Some compounds (e.g. GP 1 alkali metals, GP 2 alkaline earth metals, carbides, hydrides, inorganic chlorides, nitrides, peroxides, and phosphides) react with water or moisture in the air releasing heat or flammable, toxic gases. ■ Toxic gases such as Arsine, Hydrogen Cyanide, Chlorine, Phosphine, Hydrogen Sulphide, Nitrogen Dioxide, Carbon Monoxide, Carbon Dioxide, Hydrogen, Hydrogen Azide, Hydrogen Telluride, and Hydrogen Selenide among many others) may be evolved following the inadvertent mixing of some chemicals. This listing is not comprehensive as there are many other dangerous reactivity hazards when you are working with Dangerous Goods – you must always discuss technical matters with your own Dangerous Goods Safety Advisor and Competent Person(s) regarding the vagaries of your specific operations.
