WITH temperatures this week reaching the low to mid 30s, the Snowy Monaro Rural Fire Service is urging residents and visitors to take care when operating machinery or undertaking activities that could cause a spark.

Inspector Langdon Gould said on Monday, ahead of the forecast high temperatures, it is vital that people reduce the risk of potential ignition events.

"Ignition management, and stopping these from turning into fires, is the number one priority," he said.

Four points Inspector Langdon emphasised include:

1. No lighting of fires without a permit - apart from cooking fires;

2. Take great care in driving any vehicles, especially those with a hot exhaust, through dry grass;

3. Slashing activities should take place only in the early morning or late afternoon; and

4. Have water on hand when undertaking hot work, such as grinding or welding, and avoid the hottest part of the day.

"We urge everyone to be careful over this holiday period to avoid starting any fires," Inspector Gould said.

"Visitors and residents over the Christmas and New Year break who may be celebrating in and around our lakes and national parks, must ensure campfires are fully extinguished, not left burning, so we don't have any avoidable fires over this busy time.

"The Monaro Rural Fire Service thanks the volunteer members of the rural fire brigades for their ongoing efforts and dedication in keeping our community safe from fires.

"We wish everyone a safe and merry Christmas and please heed our advice to be careful over this holiday period with starting fires."
