dangerous goods explained

They are goods which pose any type of hazardous threat to either people, property or the environment. Anything which is flammable or could explode, be poisonous, corrosive or have the possibility of sudden decomposition should be considered a dangerous good or a hazardous material. These goods are usually present in some form in most business regardless of their size.

If you are unsure then you should ask us about your concerns

Each individual dangerous goods class has different properties. These properties need to be taken into account for a proper storage design and separation distances apply both between storages and also to other buildings and places on a site. In some cases there are also flammable vapours which will affect a design both in storage ventilation, and also where proximity to sconces of ignition can have an effect.

A consultant specialising in dangerous goods storage who is accredited with a recognised body such as the AIDGC will know how to avoid the pitfalls associated with the dangerous goods storage.

Generally every dangerous goods storage should be designed in accordance with a relevant standard or code of practice. Whilst each state is subtly different, the same principles apply everywhere. The design should be documented and compliance noted. This is the basis for a risk assessment or the way to go in order to manage hazards and risks for the storage.

In some states if more than minor quantities are to be stored, yes, in other states, notification only is required.

Diesel fuel in transport situations ( in a tanker on the road, or on a rail system ) is not considered to be a DG, however in most states, in static storage situations it is considered a DG and should be treated as such.

  • Class 2.1 Flammable gas
  • Class 2.2 Non Flammable non-toxic gas
  • Class 2.3 Toxic gas
  • Class 3 Flammable liquid
  • Class 4.1 Flammable solid
  • Class 4.2 Spontaneously combustible
  • Class 4.3dangerous when wet
  • Class 5.1 Oxidising agent
  • Class 5.2 Organic Peroxide
  • Class 6.1 Toxic
  • Class 6.2 Infectious substance
  • Class 7 Radioactive
  • Class 8 Corrosive
  • Class 9 Miscellaneous dangerous goods

Note that some dangerous goods that fall in these classes may have more than one class. These are referred to as "sub risks".

Bulk dangerous goods are generally more than minor quantities and advice from a consultant who specialises in these designs should be sought. Each design is different and, depending on such things as quantity, other dangerous goods storage, location etc will make a difference to the type, method and sitting requirements of the design.
