There is a saying that where there is smoke, there is fire. This means that if there is evidence of something happening, then it is likely that there is a fire, or cause, for it. This saying can be applied to many situations in life. For example, if there is smoke coming from a building, it is likely that there is a fire inside. If there is smoke coming from a car, it is likely that the engine is on fire. In both of these cases, the smoke is evidence of a fire, or cause.
a lamp uses electricity and a light bulb, a torch is fire
The answer is in the name. A Proximity suit is only used to get close to the fire, while an entry suit is used to walk through fire.
Almost always oxidation,the speed of the reaction is the big difference between fire and explosions(and slower yet - the "respiration" reactions that keep you alive).
Smoke comes from a fire at it's base. Hot air rises so the smoke is carried upward by the heated air
the fire door is usually rigged with an alarm that in some cases immediately calls the fire department
Fire rated doors comply with certain standards (NFPA 80) and building codes so that the door functions to reduce the spread of fire and smoke.
(ZHLS) :- Zero Helogen Low Smoke. (FRLS) :- Fire Retardant Low Smoke.
FR --> Fire Retardant FRLS-->Fire Retardant low smoke When ever wire gets fire Fr wire emit more smoke where as FRLS wire emits low smoke than the FR wires...
A front door is usually at the front of a house. The back door is kind of like a fire exit at the back of the house.
B-15 door has insulation that in case of fire can hold temperature raise up to 15 minutes. B-0 door doesn't have insulation.
its the frame on the door at the bottom which under the circumstances would block out smoke in the case of a fire :)
Yes
It has to be a fire rated door.
you use fire doors for when there is fire . fire door is for stop a smoke and fire for a few minuts for get people out and firer man to come and stop fire by water for stop fire not become bigger.
Assuming your question relates to life safety in building construction, and not to parts of a wood burning device- Smoke dampers are intended to limit the movement of smoke within a building, or section of a building. They are not intended to inhibit FLAME spread. A fire damper will inhibit smoke movement, but is also insulated to stop fire. A simple smoke damper might be light weight sheet metal- but that is not enough to stop very high temprature. A fire damper is heavier, may be insulated, built of fire resistive material, etc.
