OSH alert – Chlorine Cylinder Trailers – Placarding Requirements (May 2016)

Key learnings from a high potential incident.

HPI OSH Alert #476

It has come to our attention that many trailers used for chlorine cylinder transportation are in breach of the Dangerous Goods Safety (Road and Rail Transport of Non-explosives) Regulations 2007. This includes recently supplied trailers across the state. As such, drivers are at risk of being fined $10,000 and the Water Corporation being prosecuted.

Regulatory requirements 

In brief, the Regulations require the following placarding requirements for chlorine cylinder transportation:

  • All placards shall be a minimum dimension of 250mm x 250mm.
  • Placards shall only be displayed when transporting 250 litres (liquid capacity) or greater (One 33kg cylinder equals 29 litres, and one 70kg cylinder equals 59 litres).
  • Placards are required even if cylinders are empty (Regulators will treat empty cylinders as full).
  • Placards must be removed or concealed when carrying less than 250 litres (liquid capacity).
  • Placards must be displayed vertically.
  • Placard placement for vehicles towing a trailer must be as follows:

When displaying placards it is also important to ensure the following:

  • Must be positioned vertical on the front of the vehicle (e.g. not roof mounted or placed on bonnet).
  • Must not obscure headlights, indicators or vehicle licence plates.
  • Must not impede drivers vision, and
  • Not restrict airflow around the engine, which could impact on the vehicle operating temperatures.

Actions:

Regional and Alliance Managers  

  1. Please distribute this safety alert and communicate these changes in your region or area. 

Dangerous Goods Coordinators

  1. Review Chlorine Trailers in your area of responsibility and ensure Chlorine Cylinders are safely transported in accordance with these requirements.
  2. Where these requirements are unable to be met:
    • as an interim solution, please remove all placards from Chlorine trailers and limit the movement of Chlorine Cylinders to no more than 250 litres (liquid capacity).            
    • develop and implement a plan to ensure compliance requirements are met.

The Safety, Environment and Aboriginal Affairs (SEAA) Branch are working with Fleet Management to update design criteria to ensure all new trailers are supplied without placarding. Placarding will be required to be fitted post production by the relevant Region if it is deemed a necessary requirement. 

If you have any questions about these placard requirements, please contact Kathryn Doncon, Manager High Risk Work, on (08) 9420 2101.
