Hazardous substances and dangerous goods: the difference explained simply

Dangerous goods labelling on a transport container

Key points at a glance

Hazardous substances are substances or mixtures with hazardous properties as defined by chemicals legislation (CLP Regulation, Hazardous Substances Ordinance). This relates to labelling, storage and occupational health and safety. Dangerous goods is a term used in transport legislation (e.g. ADR) and relates to transport. A product may be a hazardous substance without being a dangerous good. Both are covered in the safety data sheet: Section 2 and Section 14.

Key messages

  • Legislation on hazardous substances protects people and the environment when handling chemicals.
  • The legislation on dangerous goods governs the safe transport of such goods by road, rail, water and air.
  • The safety data sheet contains both: classification (Section 2) and transport information (Section 14).
  • Many Eco-Nova cleaning products are not classified as hazardous and are not classified as dangerous goods.

Contents

‘Hazardous substances’ and ‘dangerous goods’ sound almost the same and are often confused. Both terms describe hazardous properties, but originate from different areas of law: ‘hazardous substances’ from chemicals and health and safety legislation, and ‘dangerous goods’ from transport law. For businesses that use, store and order cleaning products, this distinction is important.

Hazardous substances: safe handling

Hazardous substances are substances and mixtures with hazardous properties, such as being flammable, corrosive, toxic or hazardous to aquatic environments. The CLP Regulation governs how they are classified and labelled. The label features hazard pictograms as well as H-statements (hazard statements) and P-statements (precautionary statements). The safety data sheet provides the health and safety officer with information on the properties and ingredients of the substance or mixture, enabling them to carry out a risk assessment and determine the necessary protective measures.

Dangerous goods: safe transport

Dangerous goods are substances and articles that may pose a hazard during transport. They are classified in accordance with dangerous goods regulations, transported in approved packaging and labelled with hazard labels and a UN number. The consignment is accompanied by a transport document. There are exemptions for small quantities, such as for ‘Limited Quantities’. We explain what the UN markings on packaging mean in this article UN authorisation.

One without the other

A product may be classified as a hazardous substance without being classified as dangerous goods. An example from our range: the release agent Antistick 130 bears the GHS08 pictogram (health hazard), but according to the safety data sheet, it is not classified as dangerous goods under ADR. Conversely, a substance may be subject to stricter regulations during transport than when being handled in the workplace. It is therefore always essential to consult the safety data sheet: Section 2 for classification, Section 14 for transport.

What this means for your cleaners

If a cleaning product is neither a hazardous substance nor a dangerous good, many things become much simpler: no hazard pictograms, less effort required for storage and training, and transport is not subject to dangerous goods regulations. Many of Eco-Nova’s cleaning products are not classified as hazardous and are not classified as dangerous goods. However, for certain tasks, cleaning products containing hazardous substances are still required today. In such cases, we ensure the correct classification, suitable packaging and the necessary documentation.

FAQ

Frequently Asked Questions

What is the difference between a hazardous substance and dangerous goods?
The term ‘hazardous substance’ refers to the risks associated with handling it, for example in the workplace. The term ‘dangerous goods’ refers to the risks associated with their transport. A product may be classified as such without being classified as dangerous goods.
Where can I find the shipping details?
In the safety data sheet, Section 14: UN number, class, packaging group and, where applicable, environmental hazards.
What are H- and P-statements?
H-statements describe hazards (Hazard Statements), whilst P-statements provide safety advice (Precautionary Statements). Both are set out in the CLP Regulation.
Can a hazardous substance not be classified as dangerous goods?
Yes. The release agent Antistick 130, for example, bears the GHS08 pictogram, but according to the safety data sheet, it is not classified as a dangerous good under ADR.
