Engineers do have an important role in reducing risks posed to society by modern technology, its products, and its wastes. Although engineers cannot bear the total blame for safety and health risks, they are able to help reduce them to levels acceptable to society. In planning, design, operations, maintenance, or management activities, engineers should know how to eliminate, reduce, or control safety and health risks within their sphere of responsibility. Every engineer must know when and how to use other professions, including safety professions, in analyzing and reviewing their procedures and design decisions.
