Fire chiefs are considering the future of as many as 356 fire stations as a strategic view launches.
The Scottish Fire and Rescue Service (SFRS) say "nothing is off the table" as the job of the service evolves.
The number of fires has fallen by 56% since 1990, while the numbers of fatalities has dropped from 116 in 1990 to 42 last year.
However, the number of wildfires and floods has risen in the last decade.
And the service says some stations are in the wrong place to deal with weather-related issues, while others are no longer fit for purpose or too expensive to fix.
"Risk in Scotland has changed dramatically," Deputy Chief Officer Stuart Stevens said.
Speaking to BBC News, he added: "It is now incumbent on us to make sure our resources are aligned to that risk, having the right people in the right place at the right time."
The review suggests that firefighters could be deployed to back up other emergency services, including the ambulance service.
Financial concerns
The SFRS has received £32.5m of funding each year for the last seven years from the Scottish Government, with an additional £10m provided in 2023/24.
But the service says it'll need nearly double what it gets - £60m in total - to address concerns with buildings and bring equipment up to standard.
In 2019, 14 stations in Scotland were identified with RAAC, while other stations rely on wet wipes to clean equipment.
The service also wants more investment into training with younger firefighters less experienced in fighting fires due to how few there is now.
As well as fires, under the current remit, the SFRS delas with road accidents, transport incidents, flooding, building collapse and chemical incidents.
