An important consideration in engineering is ethics. Whether it is a product or a manufacturing process, there are ethical decisions to be made. How many safeguards does the process need to have? How safe does the product need to be? Can the product contain a toxic material because it is cheaper than the alternative?
Many times, guidelines from powerful organizations, such as OSHA, are available that enforce ethical decisions and to what degree they are to be enforced. Without these powerful organizations there would be little incentive for companies to develop enhanced safety features, other than normal market competition. Certainly the market could use safety features as a competitive advantage, and that does exist, but without harsh protocols and penalties, it is hard to believe that safety features would be implemented as readily as they are today. The reason is simply this: developing and implementing safety features costs money and creates many engineering problems that require solving, such as what feature is to be made, where to install it, and how effective it is. A company has little incentive to self-impose higher costs. Business decisions are made based on needs and profits; if there is no “need” for a feature and it costs more to implement, then there is no reason for it to exist. Safety protocols and laws provide the need in many cases.
