My husband works in a geothermal plant. Every year, their company supplies them with safety products such as safety shoes, hats, eyeglasses, gloves and more. Here at home, he already has two safety shoes and next year he will have another one.

Speaking about safety products, I don’t have any idea how the business runs. If companies who use safety products change their issues per year, how does this become profitable as a business? Idea, anyone?
