When I joined the fire service in 1963 fires in houses usually involved woollen fabrics and upholstery, when we arrived the furniture was only smouldering and there was little smoke. Milkmen were famed for daring early morning rescues. Crews rarely used breathing apparatus and 2 firemen with a low pressure hose reel quickly dealt with the fire. Clean out the room and you could be using it again tomorrow.
Those times are long past, the fire load in modern homes and domestic workshops is incredibly high due to the huge quantities of man made materials, fires develop and spread very quickly while creating large volumes of toxic smoke. Firefighting now is at least 4 B.A. and high volume, high pressure jets; the building will require a complete restoration.
Fire extinguishers etc may be effective if you are in the room at the time, know how to operate it and more importantly know not to waste it the flames. A one litre unit will be empty before you have aimed it properly. Fire extinguishers etc instil false re-assurance and may cost you your life.
Many people carry a fire extinguisher in their car. Modern cars have a fire load of 25Mw, you calculate how much water is needed to quench that. I will run away.
Do what firefighters do at home, install 10year fire alarms throughout the premises, you can't react until you know there is a fire. Every locked exit door should have its key on a hook on the hinge side of the door and you should check it's there every night.
When a fire alarm sounds, quickly gather your family together and leave by the shortest route. Do not try to find out what is on fire and never try to put it out.
Firefighter's families always laugh at them when staying in hotels. When we reach our room we don't check the bathroom, we come back out and trace our escape routes left and right. 10 steps to fire door, turn right , 12 steps to staircase, 13 stairs to the first flight....etc until we reach the final exit door, which we open.
Get out and Stay out. I know firefighters are far more wary of fire than you are.
