It's part of the issue for igniting prescribed burns....it's the igniting agency that caused it and may be held liable not just for burn damages but indirect effects. The US uses a position called the "Burn Boss" who signs off that the burn is valid, within paramaters for weather, fuel conditions, and has the needed support...and there are several court cases going on currently where the Burn Boss has been arrested and/or charged with negligence due to escapes/becoming an uncontrolled wildfire.
Canada tends to use the role of an Incident Commander but most agencies again use a series of checks. Burns may be cancelled not due to conditions on site for example but due to forecasted wind events coming in, fires breaking out in other area that would put response in conflict (support burn or new starts), or new intelligence coming in last minute.
With the authority/legal power to light a fire also comes with the responsibility to contain and control it.
