A couple of people here have posted about evacuating as if it is no big deal. It is a big deal, and as I poster earlier in a link, could lead to permanent injuries.
The people who commented, me included, I think would see it as risk management -- with the context of being told to shut the aircraft down on the runway, which based on the information available at that time to the crew, I wouldn't be surprised if they agreed with.
A refusal of that and delay to taxi to an isolated area at a large airport -- for stairs -- would seem a substantial risk. But hey maybe everyone else disagrees.
Of course, once told by a fire crew that there is a fire, one will evacuate which is what the Air Transat crew did(based on fire crew analysis error).
But here is how it should work and what I would consider to be the way things are handled to avoid an unnecessary evacuation(competent fire crew are required, of course) with no delay involved. One can shut down an engine on the right side( or both and then restart)...
G-ZZZA, a Boeing 777-200 aircraft operated by British Airways, was conducting flight BAW174
from New York/John F. Kennedy Intl (KJFK), NY to London/Heathrow (EGLL), UK with 13 crew
members and 196 passengers on board. During cruise flight at FL370, at approximate location
51°05' N, 043°31' W, the flight crew received a CARGO FIRE FWD EICAS message. The
emergency checklist was executed, and a MAYDAY was declared. The flight crew descended off
the North Atlantic Tracks (NAT), and offset their route for a diversion to St. John’s Intl (CYYT), NL.
The cargo hold fire extinguishing bottles were discharged, however the fire warning persisted. The
aircraft landed in CYYT and was met by ARFF. No heat or smoke was detected by emergency
services, and the aircraft was cleared to taxi to the gate.
Maintenance personnel subsequently inspected the aircraft and found no evidence of heat or fire.
The fire warning system detector was considered faulty, and was replaced. The fire extinguishers
were also replaced.`
Pretty much answers the question in this post...

And only if there is any secondary evidence of a fire(smoke, etc), whether before or after the firefighters analysis....evacuate.
