Why, when a person of higher rank, comes in do they solute? is it for respect?
depends. If you have those that monitor the windows for being broken. A loud enough sound can cause a pressure wave to hit a window and trigger it. Its not easy, but its possible. Sometimes mine go off, because of extreme cold which is very unpleasant at 3am.
For a fire to start you need 3 things (known as the fire triangle): fuel - in a condition where it can burn oxygen usually from the air heat/ignition source - to start the fire and keep it going To extinguish the fire you remove 1 or more of these 3 things remove the fuel - eg close the tap and shut off the gas remove oxygen - a CO2 extinguisher or a fire blanket remove heat - spray with water
components of fire: fuel air heat without any of these, there is no fire.
