Recommendations:

For FBC $(90\%$ efficiency$)$

a$.$ Analyze each country's current risk state for fatalities using the ALARP model.

b$.$ Cost per life

i$.$ Step $1$: Employ the cost per life ALARP method using the investment $($installation $+$ maintenance$)$ cost only

ii$.$ Factor in savings from avoiding fatalities as well as the human capital $($using $50\%$ of the lost income for $40$ years$)$ in your calculations and recompute the ALARP cost per life.

c$.$ Calculate the cost per event saved.

d$.$ Based on all of the above, decide which countries

i$.$ must implement $($as a mandatory requirement$)$

ii$.$ should implement based on ALARP cost per life and how many barriers

iii. should implement based on ALARP cost per event and how many barriers

e$.$ Order the results by the level of their importance.

For $HBC$

a$.$ Perform the same steps $($duplicate the sheet in the excel file and replace the efficiency of $90\%$ with $50\%,$ the one$-$time installation cost of $290K$ cost with $80K$ and the yearly maintenance cost of $7K$ with $0\mathrm{.}8K)$

Based on the above, formulate a conclusion.
