Gas leak

If there is a gas leak, do not activate building alarms, use mobile phones, hand held radios, electronic equipment or light flammable material in the area.

If the leak is significant or not localised then call 000 immediately from a landline or on a mobile a safe distance away from the contaminated area.

Gas or hazardous chemical vapour leak

  • If you discover a gas leak, shout a warning to alert those nearby.
  • Do not activate the building alarms – pass the alarm by word of mouth or send someone for help.
  • Ensure the immediate safety of anyone within the vicinity of the contaminated area.
  • Evacuate the immediate area around the leak, avoiding the area of contamination as best as possible and close doors.
  • If safe to do so, turn off the ventilation, machinery and ensure that naked flames are extinguished and check that the nearest gas isolator switch is off.
  • Do not switch any electrical equipment (including light switches) ON or OFF, as these may spark and become an ignition source.
  • After you have evacuated the area, in a safe area away from the source, call Security on 1800 646 501, If it is necessary to use a mobile phone, move several metres away from the immediate area before using the mobile phone - if you haven't already done so.
  • Tell Security you have a “gas leak” giving exact location and type of material involved.
  • Follow internal procedures after activating the above.
  • Anyone who has been exposed must, if safe to do so, be moved to a safe decontamination area. The treatment of serious injury must take precedence over decontamination and containment.
  • It may be necessary to turn off the air conditioning to restrict the spread of gases and vapours. Call Facilities Management to shut down or isolate the airconditioning to that area.

Evacuation due to a gas leak

  • Evacuate the building as instructed to do so by staff/emergency services
  • Walk quickly and calmly to the assembly area or as advised by staff/emergency services
  • Remain in the assembly area in groups.


Every effort must be made to prevent undue spreading of contamination - however, fire fighting must take precedence over the control of contamination.

Lecture theatres and laboratories

It is the responsibility of the lecturer or tutor to ensure that their class is evacuated and to maintain control of the students during the emergency until released by a member of the ECO or emergency services.

Clean up

Do not re-enter the area until it has been decontaminated by personnel trained and equipped specifically in chemical safety.

For any clean-up activities there must be a minimum of two people.
