Frank B. Gilbreth, Fatigue Study: The Elimination of Humanity's Greatest Unnecessary Waste (1916)
“ Put the goggles or nostril-guard, or other device, on the worker, that will insure to him clean air and decent working conditions. Make a scientific attack upon the problem later, but put in a safety device now, even if you have to change some of it next week. You will gain the immediate return that will make the investigation pay from every standpoint in the changed attitude of your workers, if in nothing else. The Museum of Safety Devices, with its energetic and enthusiastic secretary, will show you what has been done and what can be done in the line of safety. ”
