$($a$)$ A $300kg$ tank of butane has been installed at MVL Sdn$.$ Bhd$.$ The tank is about $00$ meters from the administration building.

$($The energy of explosion of TNT is $4686k\frac{J}{k}g.$ The heat of combustion for butane; Lower: $-2657\mathrm{.}5$ kJ$/$mol$,$ Upper: $-2877\mathrm{.}5$ kJ$/$mol$.$ MW: Carbon $-12$; Hydrogen $-1).$

i$.$ Compute the side$-$on peak overpressure, if the explosion is occurred on the air and assume the explosion efficiency is $2\%.$

ii$.$ Based on your answer in a$($i$),$ determine the percentage of asset loss due to the explosion occurred.

$($a$)$ Administration control $($AC$)$ and personal protective equipment $($PPE$)$ are the two types of control measures can be used to mitigate hazard. These often found to be less effective. Point out the reason for its less effectiveness.
