Just the other day I was sitting in one corner of the MRT
train.... Then I noticed a change in the fire extinguisher on
display for emergency usage... So it has been changed (I think?) to
a much larger one.... And somehow I have to agree that it might
sounds logical to have a larger one as if a fire is to break out on
a MRT.. I bet it won't be an easy one to fight....
YET, on the other hand I was thinking... The fire extinguisher
looks like something of at least 10 kg or so.... Holding it up
efficiently (bringing it quick to a fire point) during an emergency
would certainly be a problem for most smaller built teens, females
and older folks... And to fight with it (meaning you'll have to
hold the hose with 1 hand (for many people it has to be effectively
the master hand) and manipulate the 'monster' using the other hand
alone (you'll have to move closer to the fire to fight it or back
away when it gets too fierce?) could be really quite a challenge
for someone who may even be moderately fit...
Hence, I suggest why not put up more smaller fire extinguishers
instead of just one such a large one which might not even be
practical for usage during emergency
