Door...

My 1st post here... just wondering how come the bus has only 1 emergency door at the right... what if the bus falls on the right how to escape??
-
still got 2 doors on the left mah.....

What if also cant open?Originally posted by BearBear®:still got 2 doors on the left mah..... -
Not all buses have emergency exit doors. The new generations of superbuses and all bendy buses (plus other model of buses) do not have any emergency exit doors, when in emergency, passengers are to break the glass windows with the hammers provided or use any hard objects.Originally posted by KrU:My 1st post here... just wondering how come the bus has only 1 emergency door at the right... what if the bus falls on the right how to escape??
If the bus fell to the right, then exit via the front or rear windscreen by breaking the glass, it's quite difficult to get out from the left side in this situation, as the left side become the "roof" of the bus. -

However in the case of double deckers, if the stairway is obstructed in an accident, I wonder how the upper deck passengers escape. Wait for rescue or just jump down? What if there is a fire on the upper deck and stairway is obstructed?Originally posted by KrU:Oya hor... icic... -
Jump down should be ok... at most broken hand or leg...Originally posted by tranquilice:However in the case of double deckers, if the stairway is obstructed in an accident, I wonder how the upper deck passengers escape.

Maybe...Originally posted by the Bear:burn to death? -
But it can happened that a person jumped down from the upper deck, before he can get up, the bus fall on him and crushed him to death.Originally posted by KrU:Jump down should be ok... at most broken hand or leg... -
Then the person suay loh...Originally posted by tranquilice:But it can happened that a person jumped down from the upper deck, before he can get up, the bus fall on him and crushed him to death. -
Jump. The most one could suffer is a broken arm or leg, small considering your life is still intact.Originally posted by tranquilice:However in the case of double deckers, if the stairway is obstructed in an accident, I wonder how the upper deck passengers escape.

rgd the newer buses with breakable emergency exit windows:
Some windows are not labelled with the word Emergency Exit, although there is a hammer next to it...I wonder if the Emergency Exit glass panel is manufactured differently from the rest...coz during an emergency, passengers will panick and if they hit the wrong window and it doesn't break, it could be very disesterous.. -
I was thinking all the windows are manufactured similarly. The material used could vary, though.Originally posted by SBS3688Y:rgd the newer buses with breakable emergency exit windows:

It should be the same. Though there aren't stickers on all windows, I don't think that implies that the other windows are not meant for emergency exits. The materials used for the windows should also be the same.Originally posted by SBS3688Y:rgd the newer buses with breakable emergency exit windows:

Erm, actually the emergency windows are made differently. They are far stiffer and more brittle. Go observe it, tap on the windows desginated as emergency and normal windows, you'll realize that the emergency window is much stiffer. Also, if you observe, when the bus is in motion, the normal windows actually flex while the emergency ones a lot less.
I think the normal windows are far tougher then the emergency windows, they won't break as easily as the escape ones.
And if you are a fit person who is normally agile, not obese, you should be able to jump from the second deck with no injuries at all. It's actually quite a short drop of only 2.8 meters, less if you hang off the edge before letting go. -

Hi all,
Regarding the Emergency Exit windows on the newer buses, I enquired about this to TIBS and they have since replied. Following is the excerpts:-
Dear Mr XXX
Thanks for your email message. We wish to take this opportunity to assure you that all the windows are breakable and can be used as emergency exits. The emergency hammers are placed at different locations for easy access.
Have a nice day.
Warmest Regards
XXX XXX
Hopes it enlightens everyone.
Cheers and warm regards -

I think so too....the hammers are not the usual plastic hammers....they are rather heavy and weighted inside with a sharp pointed tip at the end to increase its momentum during the swing...
Physically, i dun want to go into the proof, but it is entirely possible to knock the entire window out nicely, any of them as they are tempered so there is no risk of glass shards or powder. In fact, a normal person exerting a decent 50N of force on it can easily make a rather huge dent on the aluminium body, depending how much the hammer goes into the material and the struts.
Sorry to whoever it was i dun think your logic would hold water and shatter, the only and precise reason why it vibrates less is because it has a large sticker on it that binds the upper surface of the solid mixture of molecules of the glass together, hence, the movement of adjacent particles would be restricted or rather reduced as the vibration we observe is the temporary shifting of the molecules, thus the glass would appear to be "stiffer". As a result, as the glass pane is subjected to the same deformation force as the others, the energy that is not done to vibrate the molecules due to the restricted vibration is transferred to other parts or lost as very minute amounts of heat as the particles gain internal energy, according to the first and second law of thermodynamics
The elasticity constant of tempered glass is lower than that of the normal lead glass that we use normally, hence a large force would cause a minimal expansion of the glass and the force transmitted is sufficient to cause the resin or mixture the molecules are bonded to to shatter and crack, causing the resin, and the resin with the attached molecules and particles with fall collectively, thus there is no , or very minimal glass powder when broken, thus it is also known as safety glass. -

Sorry...duplicate post -
Mr 1186Z, I don't think you need to show off your Chemistry skills from our "shared" Chemistry teacher!
Yes, I half-expected all the windows to be breakable in case of emergency. It just isn't logical to mount the hammers on every pillar. -

I thought what he said involves the principles of Physics.

BTW send my regards to her....
Superbus is correct.....all that i had said came straight out of my lecture notes on a Physics option topic called Deformation of materials.....at A level the boundary between Physics and Chemistry is very fuzzy..... -
Somehow your explaination is rather hard for people who don't study A Level sciences to understand. Hope to hear them, if possible, in layman terms.Originally posted by TIB1186Z:I dun think i am showing off......just that using scientific explanations is the best and foolproof way to comment on something without anyone doubting it.
