I think as far as possible, is what is literally should be, because the human life is worth more than anything. We shouldn’t worry too much about cost of making product because people will pay more money with higher qualities than pay less for a product that could be harmful for you. It will also end up costing you too much money if you get caught. The best example is ford pinto case, where they had to spend millions because they were too stingy to spent $11 per car, after that they had to spend even more per car.
