Site alarms and what they mean

Site alarms and what they mean

We regard the safety of our staff, neighbours and surrounding community as our top priority. Our goal is to keep you safe and it is important that we keep you informed about our operations.

From time to time you may hear alarms or sirens from the site.

The important thing for all our neighbours to remember is that if you hear an alarm; do not be alarmed and do not approach the site. Emergency Services Personnel (Police, Fire or SES) will contact neighbours in the event that you need to take action such as staying indoors. Through our Neighbour Direct service, we can also provide you with up to the minute information in the unlikley event of an incident. This is an additional safeguard we offer to our neighbours to ensure that you have the right information at the right time. To find out more about Neighbour Direct click here

The purpose of our alarms is to inform our workforce that the workplace is to be vacated to an assembly area. The table below describes the department sirens and what they mean. It also shows the time of the weekly department siren test.

An overall site evacuation alarm is currently being tested and information about the site evacuation alarm will be provided here following community consultation.

If you would like to discuss our site alarms please contact us on 03 6278 4444 and ask to speak with the Safety Superintendent.
