What are Dangerous Goods?
Dangerous Goods are articles or substances which are capable of posing a risk to health, safety, property, or the environment when transported. If not handled correctly, Dangerous Goods could harm you, the driver, receiver, other shipments or the environment.
If you’re not sure whether your shipment is dangerous or not, ask the manufacturer or supplier for a Material Safety Data Sheet (MSDS). If it contains a United Nationals (UN) number, it is a dangerous good.
Types of Hazmat Classes
Products that are considered Hazardous Materials:
- Class 1: Hazardous Materials – Explosives
- Can be identified by an explosive tag.
- “Explosive substance” refer to a solid or liquid substance, or a mixture of solid, liquid or solid and liquid substances, which —
- (a) by chemical reaction, is capable in itself of producing gas at such a temperature, pressure and speed as to cause damage to its surroundings; or
- (b) is designed to produce an effect by heat, light, sound, gas or smoke, or any combination of these, as a result of non-detonative self-sustaining exothermic chemical reaction;
- Examples: Grenades, dynamites and fireworks.
- Class 2: Hazardous Materials – Gases
- Split into 3 divisions.
- Flammable (also called combustible)
- Examples: Aerosols, insecticide gases
- Split into 3 divisions.
- Class 3: Hazardous Materials – Flammable Liquids
- Any liquid that has an ignition point at or above 37.8°C and below 60.5 °C.
- Examples: Acetone, Gasoline, Paints, Ethanol etc.
- Class 4: Hazardous Materials – Flammable Solids
- Any solid that readily combusts when exposed to a heating agent
- Examples: Activated carbon, sulphur, matches etc.
- Class 5: Hazardous Materials – Oxidizing Agents and Organic Peroxides
- An oxidizer is a chemical that readily yields oxygen in reactions, thereby causing or enhancing combustion.
- Examples: Ferric nitrate, hydrogen peroxide, fertilizer etc.
- Class 6: Hazardous Materials – Toxic and Infectious Substances
- Poisonous material is a material, other than a gas, known to be so toxic to humans that it presents a health hazard during transportation
- Examples: Pesticides, medical/blood trials, motor fuel anti-knock mixtures, and tear gas.
- Class 7: Hazardous Materials – Radioactive Substances
- Radioactive substances are materials that emit radiation.
- Examples: Uranium, radioactive ores, isotopes and some medical equipments or parts.
- Class 8: Hazardous Materials – Corrosive Substances
- A corrosive material is a liquid or solid that causes full thickness destruction of human skin at the site of contact within a specified period of time.
- Examples: Sulfuric acid, strong bases such as sodium hydroxide, batteries and bleach.
- Class 8: Hazardous Materials – Miscellaneous
- The miscellaneous hazardous materials category encompasses all hazardous materials that do not fit one of the definitions listed in Class 1 through Class 8.
- Examples: Magnets, lithium ion batteries, electronic devices, air bag modules and motor engines.
PSA Dangerous Goods Standards
PSA adheres to their own set of standards for dangerous goods:
- PSA Standards: 1, 1D, 1S, 2, 2A, 2B, 2S, 3
Dangerous goods in this classifications are recommended for 24H storage:
- 1S, 2S, 2A, 2B, 2F, 3
Dangerous goods in this classifications are not recommended for storage:
- 1D, 2

What are some vehicles that can transport Hazmat goods?
Any vehicle that is used for the transportation of petroleum or flammable materials must be issued with a transport license. This license needs to be shown in the driver’s cabin at all times.
All drivers of hazmat transport vehicles need to have a valid Hazmat Transport Driver Permit (HTDP). As to safeguard other road users will be able to recognize hazmat transport vehicles, it is a must for tracked vehicles to carry orange-colored license plate. Prior to the approval of the license, vehicle is to undergo a third party inspection to meet the required safety standards.

How do I get a Hazmat License?
Anyone who engaged in petroleum storage, dispensing or transportation without license may face a maximum fine of $10,000 and / or imprisonment of 6 months.
What if I am transporting small amounts of hazmat goods?
The transportation of petroleum and flammable materials in the following quantities are exempted from licensing:
- Less than 130 kg (gross weight) in not more than 2 cylinders;
- Less than 20 litres of Class I petroleum; or
- Less than 200 litres of Class II and Class III petroleum.
- Less than 130 kg (gross weight) in not more than 2 cylinders of flammable gases;
- Less than 20 litres of flammable liquids; or
- Less than 10kg of flammable solids.
