Since the dawn of the industrial revolution—and particularly within the last 50 years— there has been marked, continuous improvement in workplace safety. Companies have invested in personal protective equipment (PPE), such as hard hats, safety masks and eyewear, flame-resistant clothing, chemical-resistant gloves and earplugs. They’ve also developed safety management systems to identify hazards and control risks. In addition, the formation of the Occupational Safety & Health Administration (OSHA) 45 years ago has helped dramatically improve workplace safety.
