DANGEROUS CARGO

Class 1 explosives are substances or articles that can explode by chemical reaction, releasing massive gas and heat suddenly. Divided into 6 divisions (1.1–1.6) by hazard level, they include ammunition, fireworks, detonators, and blasting explosives. In international logistics, they require strict packaging, separate stowage, and special transport permits, with rigid limits on loading quantity and handling procedures to prevent ignition or detonation during transit.

Class 2 covers compressed, liquefied, or dissolved gases under pressure, split into flammable (2.1), non-flammable non-toxic (2.2), and toxic (2.3) gases. Examples are LPG, oxygen, chlorine, and acetylene. These gases are transported in pressure cylinders, with packaging complying with pressure test standards. Logistics operations need leak detection, temperature control, and separation from incompatible goods; toxic gases demand extra protective measures and ventilation.

Class 3 includes liquids with a flash point ≤ 60°C, which easily vaporize and ignite when exposed to heat, sparks, or open flames. Typical goods are gasoline, ethanol, paint, and solvents. They require sealed, corrosion-resistant packaging and are stored/transported away from ignition sources. Ventilation and static elimination are critical in logistics; liquid level monitoring and spill response kits are mandatory to avoid fire or explosion risks.

Class 4 has three divisions: flammable solids (4.1), spontaneously combustible substances (4.2), and water-reactive substances emitting flammable gases (4.3). Examples include matches, phosphorus, sodium, and camphor. These goods need moisture-proof, fire-resistant packaging. Logistics operations ban mixing with oxidizers; temperature monitoring is essential for Division 4.2, and dry stowage is compulsory for Division 4.3 to prevent contact with water.

Class 5 includes oxidizing substances (5.1) that release oxygen to intensify combustion, and organic peroxides (5.2) prone to exothermic decomposition. Examples are hydrogen peroxide, potassium permanganate, and benzoyl peroxide. They require shockproof, temperature-controlled packaging and must be isolated from flammables, organics, and acids. Logistics handling prohibits friction or heating; organic peroxides often need low-temperature transport to avoid decomposition.

Class 6 comprises toxic substances (6.1) causing death or injury via inhalation, ingestion, or skin contact, and infectious substances (6.2) containing pathogens. Examples are cyanide, pesticides, and clinical waste. They use leak-proof, tamper-evident packaging with clear hazard labels. Transport needs isolated stowage, protective gear for handlers, and strict waste disposal protocols; infectious substances follow WHO and IATA packaging instructions.

Class 7 includes substances emitting ionizing radiation, categorized by activity level (I–III). Examples are uranium, radium, and medical radioactive isotopes. Packaging follows three-tiered standards (Type A/B/C) to contain radiation. Logistics requires radiation monitoring, limited transport speed, and separate stowage from passengers and food. All handlers must wear dosimeters, and transport documents include radiation activity certificates.

Class 8 substances destroy living tissues or corrode metals, including acids (sulfuric, hydrochloric) and alkalis (sodium hydroxide). They use corrosion-resistant, sealed containers with secondary leak-proof liners. In logistics, they are isolated from oxidizers, flammables, and foodstuffs. Handling requires acid/alkali-resistant protective equipment; spill response uses neutralizers, and storage areas have anti-corrosion flooring to prevent environmental contamination.

Class 9 covers dangerous goods not fitting other classes, posing risks like environmental harm, magnetism, or elevated temperature. Examples include lithium batteries, dry ice, asbestos, and magnetized materials. Packaging and stowage follow specific IMDG provisions; lithium batteries need insulation to prevent short circuits, dry ice requires ventilation for CO₂ dissipation. Transport documents must specify hazard characteristics and special handling requirements.
