Most companies have limited budget and need to be prudent on what monies they spend, even for safety. Your company averages $4,500 costs per worker's injury. Your company uses a rate of 9% per year return on investment. You have two projects. Project A costs $13,000 and you estimate you could save one injury per year of the next 12 years. Project B costs $18,000 and you estimate you could save 18 injuries over the same period. Which project do you recommend? (Assume equal distribution of injuries.)
