A man who died from burns sustained while trying to extinguish a grassfire in northwest NSW last week is being remembered as "a true gentleman" who would do anything for his tight-knit community.
Warwick "Wokka" Ranclaud, 36, was driving a front-end loader to help extinguish a blaze off Coonabarabran Road in Caroona, near Tamworth, when he was surrounded by flames on Thursday.
The fire broke out at the JBS Australia Caroona Feedlot, where Mr Ranclaud was working, just before 6pm.
He was airlifted to Sydney's Royal North Shore Hospital in a critical condition after sustaining third-degree burns to 60 per cent of his body, according to the Northern Daily Leader, but died on Saturday.
Residents of the nearby town of Spring Ridge, with a population of around 400, have taken to social media to mourn the death of one of their own.
"You were one true gentleman Warwick. You always helped in every which way that you could for anyone. You will be very sadly missed. Our condolences to your heartbroken family," Sonia Green wrote on a Facebook post.
Phil Wilson said: "RIP Wokka you were a great bloke and will be sadly missed."
"A true Gentleman, you were the most gentle soul I've ever met," Kristine Lynnette added.
The Rural Fire Service was called out to the fire just before 7pm, with the 10-hectare blaze extinguished by 11pm, an RFS spokesman confirmed on Monday.
Safework NSW is investigating the incident.
"Initial inquiries indicate the incident occurred when a farm vehicle that was being used to assess grazing land sparked a fire," the workplace regulator said in a statement.
"A 36-year-old man working in a front-end loader nearby attempted to assist workers to extinguish the fire but sustained burns to his body."
AAP understands Mr Ranclaud had been working at the feedlot as a contractor for JBS Australia.
The company has been contacted for comment.
