The fire was fought by 1,680 firefighters from throughout the country, and was put out by 16:00 local time. Several anecdotes indicate that the poorly equipped fire crews and access difficulties (especially at Rua do Carmo) combined with the extensive flammable contents (including gas bottles for sale on the stores) meant the firefighters struggled to cope with such a large scale urban fire. Two people were killed, and 73 were injured (60 of them firemen). Between 200 and 300 people lost their homes, and close to 2000 people lost their jobs. In terms of the extent of the city affected and number of destroyed buildings, the Chiado fire is often considered the worst disaster to strike the city since the 1755 Lisbon earthquake. Although it is known that the fire started with a slow combustion on the top floor of the Grandella building (which is unlikely in the event of intentional fire, that typically spreads quickly) the cause was never fully determined.
