Seven people have died during 842 residential fires during this winter and 78 people have been injured.

A blitz on smoke alarms in Warren last weekend had a dual goal: improving community fire safety and highlighting the work of the local Warren Brigade, with a hope to attract more members.

Fire and Rescue NSW (FRNSW) crews visited all 785 homes in Warren last weekend, offering residents crucial home fire safety advice and checking for working smoke alarms.

Residential fires in 2023 have seen a five per cent increase in deaths and a 21 per cent rise in injuries, compared to winter last year.

In almost half the home fires this winter, a smoke alarm either wasn't fitted or didn't activate.

Following a similar recent safety blitz at Merriwa in the Hunter Valley, crews are keen to ensure households in Warren are protected from fire and have current home safety escape plans.

Firefighters from the district joined FRNSW to check, install or replace smoke alarms in homes.

FRNSW Duty Commander, Acting Inspector Chris Cusack, said he hopes the home fire safety blitz will safeguard the town's residents and possibly attract new members to the Warren brigade.

"Our objective (was) to visit every home in area, ensuring every home has a working smoke alarm installed. For those homes without smoke alarms we installed one free of charge," he said.

"I'm hoping that this home fire safety blitz will improve our profile in the town, improve fire safety and attract new members to the brigade."

Renee Scott, captain of Warren 491 Fire and Rescue said Brigade work was rewarding.

"I have been on the brigade for six years," Ms Scott said. "I joined to be more involved in our community and to help out those who can't help themselves."

Current Warren Brigade member Angela Muir joined the Fire and Rescue team over 15 years ago.

"I grew up around the organisation," Ms Muir said. "I'm passionate about helping and giving back to my community and I think that’s why if you were to join it would be a rewarding career. There's lots of opportunities out there available through fire and rescue."

After the door knock, crews hosted a community fun day event at Saunders Park on Saturday to encourage potential FRNSW On-call (retained) recruits.

"(It was) an opportunity to for local people to engage with firefighters, check out the type of equipment we have on our trucks and get an idea of what it's like to be a firefighter," Mr Cusack said.
