What are the 5 hazard classes?

When it comes to hazardous goods/commodities, the hazard class is represented either by the class (or division) number or by the product’s name. Placards are used to distinguish between different types of divisions of a material. If appropriate, this information is necessary for both significant and subsidiary danger classes and divisions.

Explosives 

Explosives are materials or substances that have the capability of conflagrating or detonating fast as a result of a chemical reaction occurring inside them.

Go Hazmat Hub can service any client demands connected to the logistics of explosives, including but not limited to packing, packaging, compliance, freight forwarding, and training requests.

When a chemical reaction takes place, explosives can create gasses at temperatures, pressures, and speeds that are high enough to inflict catastrophic destruction by force and produce additional dangerous levels of heat, light, sound, gas, or smoke.

Munition or cartridges, fireworks or pyrotechnics, flares, blasting caps/detonators, fuse, primers, explosive charges are all examples of items that fall into this category (blasting, demolition etc.)

Gases 

A gas is defined under the Dangerous Goods Regulations as any material with a vapor pressure of more than 300 kPa at 50°C. Compressed gasses, liquefied gasses, dissolved gasses, chilled liquefied gasses, mixes of one or more gasses with one or more vapors of imports from other groups, items charged with a gas, and aerosols are all included in this category.

Go Hazmat Hub can serve all client demands connected to the logistics of gasses, including but not limited to packing, packaging, compliance, freight forwarding, and training needs. A gas’s flammability and toxicity or corrosiveness to people make it a potentially dangerous substance.

 Natural gas, oil, and petrochemicals Gasses derived from petroleum Butane, Propane, Ethane, Methane, Dimethyl ether, Propene/propylene, and Ethylene are some of the more common hydrocarbons.

Flammable Liquids

Liquids that give off a flammable vapor (have a flashpoint) at temperatures greater than 60-65°C are classified as flammable liquids. Flammable liquids are also substances transported at elevated temperatures in a liquid state and give off a flammable vapor at a temperature greater than or equal to the maximum transport temperature are classified as combustible liquids well.

Because of their volatility, combustibility, and capacity to cause or propagate major conflagrations, flammable liquids may pose a substantial threat to human safety.

Adhesives, Acetone/acetone oils, Acetone/acetone oils, Paints, lacquers, and varnishes are all types of finishes. Alcohols, Products relating to perfumery Petrol (gasoline) are petroleum products. 

Spontaneous combustibles that are “dangerous when wet.”

Flammable solids are materials that, when exposed to the conditions encountered in transportation, are readily combustible or can cause or contribute to fire through friction. They include self-reactive substances capable of undergoing a highly exothermic reaction and solid desensitized explosives, among other things. 

In addition, substances that are prone to spontaneous heating under normal transport conditions or heating up when in contact with air and are thus prone to catching fire, as well as substances that emit flammable gases or become spontaneously combustible when in contact with water, are included in this classification.

Because of their volatility and combustibility, flammable solids have the potential to cause or spread major conflagrations, presenting a substantial threat to human life and the environment.

Alkali metals, metal powders, aluminium phosphide, Sodium batteries, Sodium cells, firelighters, matches, and other similar items are all available. 

Oxidizers and organic peroxides 

Oxidizers are classified under hazardous goods rules as compounds that can cause or contribute to combustion, often by releasing Oxygen as a consequence of a redox chemical reaction (redox reaction). Organic peroxides are compounds that are derivatives of hydrogen peroxide.

 Organic peroxides are thermally unstable and may release heat due to the exothermic autocatalytic breakdown that occurs in their presence. Furthermore, organic peroxides may be prone to explosive decomposition, burn swiftly, be sensitive to touch or friction, react severely with other compounds, or cause harm to the eyes if they come into contact with them.

Sodium nitrate, Sodium persulphate, Potassium permanganate are examples of oxidizers.
