Assistant Commissioner Ian Mitchell said the service had received reports of door-to-door sales people claiming to be from the QFRS trying to inspect and sell fire safety products.
"Let me be clear that the QFRS does not proactively sell fire safety products including smoke alarms or fire blankets,” Mr Mitchell said.
“In fact QFRS personnel do not doorknock to sell any products and therefore, the public should be aware of any door-to-door sales people claiming to be from the service.
“We strongly advise if you are approached by anyone purporting to be from the QFRS, you do not let them into your home.
“We urge you to immediately report the incident to the Australian Competition and Consumer Commission or the Queensland Office of Fair Trading.”
A sales person must leave a private property if asked to do so.
