A new online portal allows residents to use their mobile phone, tablet or desktop computer to lodge their notifications about planned hazard reductions or burn offs 24 hours a day, seven days a week.

NSW RFS District Manager, Superintendent Kam Baker said by using the new tool users can help prevent unnecessary emergency calls.

"As we approach the bush fire season, many landholders are taking the opportunity to burn off - but it's important they do it safely and let us and their neighbours know," Mr Baker said.

"Landholders need to make sure they've obtained any required permits and permissions, as well as notifying neighbours and fire authorities 24 hours before lighting up.

The tool makes it easier to notify the NSW RFS before conducting a burn.

"If fire services know about it, it can help prevent unnecessary emergency calls and firefighters from being responded," Superintendent Baker explained.

By using the new tool, landholders will be notified of any Total Fire Bans and will be advised to not proceed with their burn.

"While landholders are encouraged to reduce fuel loads on their property, it is imperative that it is done so safely and legally," Superintendent Baker said.

Before lighting any fire you need to have adequately prepared fire breaks and have firefighting equipment on hand to ensure the fire does not escape.

"Every landholder has a responsibility to prevent fire spreading from their property and there can be serious consequences for people who light fires and leave them unattended," Superintendent Baker said.

To notify of your intent to burn off, use the new online burn notification tool at www.rfs.nsw.gov.au/notify.

Landholders can still notify the NSW RFS by contacting their local Fire Control Centre.
