Focused inspection campaign – risk of hazardous gases

We’re running an inspection campaign focusing on hazardous gases on class 1 and 4 vessels in NSW from Sep-Dec 2024. To prepare, include hazardous gas risks in your SMS.

Focused inspection campaign (FIC) summary

Purpose: To ensure domestic commercial vessel (DCV) owners, operators and crew have considered the risks associated with hazardous gases in their safety management system (SMS).

Location: NSW

Timeframe: 16 September until 31 December 2024

Target:

  • Class 1 passenger vessels  
  • Class 4 hire and drive vessels  

Expect to be inspected.

Why we're inspecting vessels

In August 2023, a new version of Marine Order 504 (MO504) came into effect. The revised marine order requires DCV owners to:

  • include potential risks of hazardous gases from sewage systems and other sources in their vessel’s SMS risk assessment
  • strengthen training and drill requirements related to emergency procedures.  

Inspectors will check compliance with these new operational safety requirements.  

Focus areas  

If we inspect your vessel, we will look for:  

  • evidence of a risk assessment to identify the potential risks of hazardous gases
  • written procedures for managing hazardous gases and maintaining sullage tanks and plumbing
  • instructions on how to identify and respond to hazardous gas incidents  
  • proof that you are providing hazardous gases information to hirers of class 4 vessels.  

How to prepare
