Excellent post. Mostly good advice.
If the door is hot at all, or the hallway is smoke filled, and you have an easily accessible second way out, even if it is a window, use it. With the materials found in common household products being mostly plastic, read solid oil, the intensity of fire and fire spread is so rapid today that it may change so fast that you get caught and die attempting to escape. Hydrogen cyanide is a common combustion by-product and it lingers long after the fire has been extinguished, carbon monoxide is another. Both are incredibly toxic and deadly in the right quantities.
Flashover, the state of the fire spread where everything in a room is heated to its ignition temperature and they all burst in to flames simultaneously, is occurring much early than when homes had natural fiber interior finishings. Temperatures in a modern house fire easily exceed 1000 degrees F and temps over 1500 degree F are entirely realistic today.
I have to say, in my opinion, that the only way I would wrap myself in a blanket is if it were made of natural fibers, particularly wool. Synthetics melt and would just add to your misery from burns.
If you close your door, and no smoke is infiltrating the room, it probably would be okay to open your window to make it easier to be spotted and to breath. If you think you are going to pass out try not to position yourself right under the window sill. Remember those coming in to rescue you will be coming through that window to get you and if they have to move you before they come in it simply adds to your exposure time to heat and smoke. Be close to the window so you are easy to find, but not in the entry way.
Have a meeting place outside for your family to gather at so you can take a head count and know for sure who is out. Report this information to the first arriving fire truck officer. Believe me it makes a difference how we do things if we know everyone is out versus knowing someone is still inside. If someone is inside yet, firefighters and equipment primarily focus on the rescue attempt and suppressing the fire may be given less resources initially. If everyone is out then the resources all go to extinguishing the fire as rapidly as possible. If you can identify who is missing and then tell the fire officer their most likely location that can save a ton of time finding them.
Smoke detectors and Caron monoxide detectors do indeed wear out and we go on plenty of CO detectors sounding that are malfunctioning because the are worn out. Replacing them in a timely manner may just save your life.
I have a love/hate relationship with fore extinguishers and the reason is the instructions on everyone of them is wrong. the first instruction should say "CALL THE FIRE DEPARTMENT!" The number of fires every year that get out of hand because people wait to call the fire department is simply unacceptable. Call first, or get some one else to call while you use the extinguisher. When i teach non-firefighters how to use extinguishers I always tell them this: 1) If the extinguisher is having no effect on the fire it is time to leave, 2) If you are having difficulty breathing it is time to leave, 3) If you are having trouble seeing it is time to leave. You are not expected to die using a fire extinguisher.
Good advice on the using the back of your hand. We add in the fire training world that there is always the possibility that wiring overhead had fallen on the door knob on the other side and electrified the door knob. Using the back of your hand the natural muscle reaction is for the hand to close and pull away, if you use your palm and your hand closes you may be stuck to the door knob.
My last addition would be this, if you live in the rural have the fire chief come out and do a walk around with you on your property. he doesn't have to go into any buildings but the look around to see if there is room for fire apparatus to maneuver and work, if there is an alternative water supply like a pond or river, trees, terrain and anything else pertinent may make the difference in saving your home or out buildings in case of fire.
Excellent post BlackBlade. I hope you don't mind my additional comments from a firefighter's perspective.
